This chapter describes how to install the Cisco 12016 GSR. It contains the following sections:
To prevent problems, before performing any procedures in this chapter, review the following sections in "Preparing for Installation":
In particular, observe the guidelines for preventing electrostatic discharge (ESD) damage described in the Preventing Electrostatic Discharge Damage of "Preparing for Installation,"and use Figure 2-1 in "Preparing for Installation,"as a reference in locating and using the ESD sockets on the front of the Cisco 12016 GSR chassis.
Finally, before you perform any installation procedures for the GSR, also review the safety warnings listed in the Regulatory Compliance and Safety Information for the Cisco 12000 Series Gigabit Switch Router (Cisco publication number 78-4347-xx) that accompanied your GSR.
 | Warning The Cisco 12016 GSR must be installed in a rack that is secured to the building structure. |
A fully-equipped Cisco 12016 GSR with a standard AC-input power shelf can weigh as much as 415 lb (188 kg); a fully-equipped Cisco 12016 GSR with a standard AC-input power shelf can weigh as much as 440 lb (200 kg). Because of the weight and height of the GSR, Cisco provides a rack-mounting system (see Figure 3-1) for the Cisco 12016 GSR that enables a team of two installers to insert a fully-loaded Cisco 12016 GSR into a rack, or extract a fully-loaded Cisco 12016 GSR from a rack, without removing any of the components from the GSR chassis.
The Cisco 12016 GSR rack-mounting system consists of the scissor-jack platform (provided) and rack-mounting platform (provided). You install the chassis in the equipment rack by using the scissor-jack platform to raise the chassis to the height required to insert it into the rack, sliding the chassis into place on the rack-mounting platform, and then securing the chassis to the rack or optional center-mount rack-mounting brackets with screws through holes in the rack-mounting flanges on each side of the chassis. The hole-pattern in the scissor-jack platform was modified slightly to accommodate the eight-rail 12016 chassis which begins shipping in the summer of 2000. (See the "Chassis Overview" section in Chapter 1 for a description of the eight-rail 12016 chassis.)
After it has been removed from the shipping container and shipping pallet, the GSR sits on the scissor-jack platform and is secured to it by four anchor clips that are inserted into slots along the bottom edges of the GSR chassis side panels and secured by four bolts. (See Figure 3-2.) The scissor-jack platform remains attached to the GSR until the GSR is inserted into the equipment rack.
The rack-mounting platform is a sheet-metal platform that is 17.25 in (43.82 cm) wide and 22.75 in (57.59 cm) deep. (See Figure 3-3.) Its height is adjustable from a minimum height of approximately 5.25 in (13.34 cm) to a maximum height of approximately 8.00 in (20.32 cm). For telco-style racks, the bottom edge of the platform can be raised to approximately 6.00 in (15.24 cm) to clear the cross members at the bottom of the rack. The platform is installed at the bottom of the empty rack and acts as a permanent support platform for the chassis. It can be installed in either the front-mounted position or the center-mounted position, to match the installed position of the chassis.
Before you begin the rack-mount installation, you must read and understand the information in the "Rack-Mounting Guidelines" section of "Preparing for Installation," and have the following items on hand:
A fully-equipped Cisco 12016 GSR with a standard AC-input power shelf can weigh as much as 415 lb (188 kg); a fully-equipped Cisco 12016 GSR with an optional two-level AC-input power shelf can weigh as much as 440 lb (200 kg). As an option, you can remove some of the components from the chassis to reduce the top-end weight of the chassis and lower the center of gravity to make the chassis more stable as you move it.
Procedures in the following sections describe the steps for removing some of the Cisco 12016 GSR components:
The Cisco 12016 GSR has front covers over the power shelf and upper blower module, the lower blower module, and each of the integral card cages in the chassis. (See Figure 3-4.) Figure 3-4 illustrates a Cisco 12016 GSR with a standard single-level AC-input power shelf. A Cisco 12016 GSR with an optional two-level AC-input power shelf will have a different power shelf and power-shelf front cover.
The chassis front covers for the power shelf and upper blower module, upper card cage, lower card cage, and lower blower module are fastened to the chassis by ball studs that insert into sockets on the front of the chassis. These front covers are referred to as snap-on front covers.
The partial front cover on the air filter door is fastened to the air filter door by four screws inserted from the back side of the air filter door. This partial front cover is referred to as the air filter door front cover. You do not need to remove the air filter door front cover, because the air filter door can be opened and moved out of the way to gain access to the switch fabric card cage.
To remove the snap-on chassis front covers, use Figure 3-4 as a reference and follow these steps:
Step 1 Observe the appearance and position of each of the snap-on front covers on the front of the Cisco 12016 GSR.
Step 2 Select a front cover, grasp the outside edges of the front cover, and pull it straight out to detach the front cover from the front of the GSR chassis.
Step 3 Set the front cover safely aside.
Repeat Step 1 through Step 3 for the remaining snap-on front covers on the Cisco 12016 GSR.
In a GSR equipped with AC-input power supplies, each power supply weighs 12.7 lb (5.7 kg). By removing the three power supplies from the standard AC-input power shelf, you reduce the top-end weight of the chassis by approximately 38.1 lb (17.1 kg). By removing the four power supplies from the optional AC-input power shelf, you reduce the top-end weight of the chassis by approximately 50.8 lb (22.8 kg).
In a GSR equipped with DC-input power entry modules, each power entry module weighs 6.4 lb (2.9 kg). By removing the four power entry modules from the DC-input power shelf, you reduce the top-end weight of the chassis by approximately 25.6 lb (11.6 kg).
For more information on these subsystems, refer to the "Power Subsystems" section.
 | Caution The Cisco 12016 GSR must be operated with all of its power modules installed at all times for electromagnetic compatibility (EMC). |
This section contains two procedures:
Select the appropriate procedure for your router.
If the Cisco 12016 GSR is equipped with the either the standard or optional AC-input power subsystem, you can reduce the top-end weight and lower the center of gravity of the router by temporarily removing all of the AC-input power supplies from the AC-input power shelf.
| Caution Always wear an ESD-preventive wrist strap when removing and replacing a power supply. For more information, refer to the section "Preventing Electrostatic Discharge Damage" section in "Preparing for Installation." |
To remove an AC-input power supply, use Figure 3-5 as a reference and follow these steps:
Step 1 To turn off the power supply and eject it from the shelf backplane connector, follow these steps:
(a) Lift the ejector lever spring clip to release the ejector lever from the power supply faceplate. (See Figure 3-5a.)
(b) Pivot the ejector lever away from the power supply faceplate to eject the power supply from the power shelf backplane connector. (See Figure 3-5b.)
Step 2 Grasp the power supply handle and pull the power supply halfway out of the bay. (See Figure 3-5c.)
| Caution The AC-input power supply weighs 12.7 lb (5.7 kg). Use two hands when handling the power supply. |
Step 3 Use your free hand to support the power supply while you slide the power supply completely out of the bay.
Step 4 Set the power supply safely aside.
Repeat Step 1 through Step 4 for the remaining power supplies.
If the Cisco 12016 GSR is equipped with the DC-input power subsystem, you can reduce the top-end weight and lower the center of gravity of the router by temporarily removing the four DC-input power entry modules installed in the DC-input power shelf.
| Caution Always wear an ESD-preventive wrist strap when removing and replacing a DC-input power entry module. For more information, refer to the "Preventing Electrostatic Discharge Damage" section in "Preparing for Installation.". |
To remove a DC-input power entry module, use Figure 3-6 as a reference and follow these steps:
Step 1 To turn off the power entry module and eject it from the power shelf backplane connector, follow these steps:
(a) Loosen the ejector lever captive screw to release the ejector lever from the power entry module faceplate. (See Figure 3-6a.)
(b) Pivot the ejector lever away from the power entry module faceplate to eject the power entry module from the power shelf backplane connector. (See Figure 3-6b.)
Step 2 Grasp the power entry module handle and pull the power entry module halfway out of the bay. (See Figure 3-6c.)
Step 3 Use your free hand to support the power entry module, and then slide it completely out of the bay.
Step 4 Set the power entry module safely aside.
Repeat Step 1 through Step 4 for the remaining power entry modules.
Figure 3-7 shows the steps in removing a blower module from the chassis.
To remove a blower module, use Figure 3-7 as a reference and follow these steps:
Step 1 Loosen the two captive screws on the blower module faceplate.
| Caution The blower module weighs 20.5 lb (9.3 kg). Use two hands when handling a blower module. |
Step 2 Grasp the blower module handle and pull it straight out to disconnect the blower module from the chassis backplane connector at the back of the blower module bay. Slide the blower module halfway out of the blower module bay.
Step 3 Use your free hand to support the blower module, and then slide the blower module completely out of the blower module bay.
Step 4 Set the blower module safely aside.
Unless you plan to strip all components to reduce the overall weight of the chassis so you can shift the chassis by lifting it manually, there is no advantage in removing the cards from the card cages. Reducing the overall weight of the chassis is offset by the requirement to store the cards in an ESD-preventive and dust proof (for fiber-optic cards) environment.
| Caution One edge of the card carrier faceplate is lined with an EMI-preventive gasket consisting of many raised, conductive contacts. Be careful not to damage the gasket contacts, because a damaged card carrier gasket can result in reduced EMI performance. |
The upper card cage (see Figure 3-9) has eight slots (numbered 0 through 7, from left to right). Line cards are installed in slots 0 through 6. The master GRP must be installed in slot 7. The upper card cage also has a dedicated, non-configurable slot (far left slot, labeled Alarm 0) for an alarm card. To reduce the weight of the chassis, you can choose to remove the cards from slots 0 through 7. (You can leave the alarm card in the card cage.)
To remove a card from the upper card cage, use Figure 3-9 as a reference and follow these steps:
Step 1 Attach an ESD-preventive wrist strap to your wrist and connect the leash to one of the ESD connection sockets on the front of the chassis or to a bare metal surface on the chassis.
Step 2 Proceeding from left to right, identify each card and write down the card type and card slot number on a piece of paper. When you reinstall the cards in the chassis, install them in the same card slots.
Step 3 Starting from slot 0 (left side of the upper card cage), select a card and loosen the captive screws at the top and bottom of the card faceplate. (See Figure 3-9a.)
Step 4 Place your thumbs on the ejector levers and simultaneously push the ejector levers away from each other to unseat the card from the backplane connector. (See Figure 3-9b.)
| Caution Handle all cards by the metal card carrier edges only; avoid touching the board or any connector pins. |
Step 5 Using the ejector levers, pull the card halfway out of the slot. Avoid touching the board or any connector pins.
Step 6 Grasp the card carrier edge with one hand and place your other hand under the carrier to support it. (See Figure 3-9c.) Slide the card out of the slot and place it directly into an antistatic sack or other ESD-preventive container.
Repeat Step 3 through Step 6 for the rest of the cards in the upper card cage .
The lower card cage (see Figure 3-10) has eight slots (numbered 8 through 15, from left to right) that can support a combination of line cards. If the router is equipped with an optional, redundant GRP, it must be installed in the far left slot in the lower card cage (slot 8). If the router is not equipped with an optional, redundant GRP, a line card can be installed in slot 8 of the lower card cage. The lower card cage also has a dedicated slot for an alarm card (far right slot, labeled Alarm 1). To reduce the weight of the router, you can choose to remove the cards from slots 8 through 15.
Except for the head-down orientation of the cards, cards are removed from the lower card cage in exactly the same way as described in the "Removing the Cards from the Upper Card Cage" section.
Unless you are planning to shift the chassis by lifting it manually, there is no advantage in removing the cards from the switch fabric card cage. Reducing the overall weight of the chassis is offset by the requirement to store the cards in an ESD-preventive environment.
The switch fabric card cage is located below the upper card cage, behind the air filter door on the front of the chassis. (See Figure 3-11.) The switch fabric card cage has five keyed, vertical card slots for the clock and scheduler cards and switch fabric cards. Clock and scheduler cards are installed in the left two card slots (labeled CSC 0 and 1); switch fabric cards are installed in the right three slots (labeled SFC 0, 1, and 2).
To remove or install either type of card, you must first open the air filter door to gain access to the fabric card cage.
To gain access to the fabric card cage, use Figure 3-11 as a reference and follow these steps.
Step 1 Attach an ESD-preventive wrist strap to your wrist and connect the leash to one of the ESD connection sockets on the front of the chassis or to a bare metal surface on the chassis.
Step 2 Loosen the two captive screws on each side of the air filter door.
Step 3 Grasp the sides of the air filter door front cover and swing the door out and down, away from the switch fabric card cage.
The air filter door is attached to the chassis by a pair of spring-loaded arms on either side of the door. When the door is fully extended away from the fabric card cage, it hangs down in front of the lower card cage.
To remove cards from the switch fabric card cage, use Figure 3-12 as a reference and follow these steps.
Step 1 Attach an ESD-preventive wrist strap to your wrist and connect the leash to one of the ESD connection sockets on the front of the chassis or to a bare metal surface on the chassis.
Step 2 Select one of the cards in the switch fabric card cage. Grasp the two card ejector levers and simultaneously pivot both ejector levers 90 degrees away from the front edge of the card carrier to unseat the card from the backplane connector.
Step 3 Touching only the metal card carrier, slide the card out of the slot and place it directly into an antistatic sack or other ESD-preventive container.
Repeat Step 2 and Step 3 for the rest of the cards in the switch fabric card cage, then proceed to Step 4.
Step 4 Grasp the sides of the air filter door front cover and pivot the air filter door up so that it is aligned with the opening of the switch fabric card cage and the four guide pins are inserted in the corresponding holes on each side of the switch fabric card cage.
Step 5 Push firmly on the air filter door until it is seated in the opening of the switch fabric card cage, then tighten the four captive screws.
| Caution The air filter door must be closed and secured at all times to maintain correct EMI performance. |
The Cisco 12016 GSR chassis can be installed in the rack either in a front-mounted position or a center-mounted position. (See Figure 2-3 in "Preparing for Installation." In the front-mounted position, the chassis rack-mounting flanges are secured directly to the rack posts. In the center-mounted position, an optional set of center-mount brackets are secured to the rack posts and the chassis rack-mounting flanges are then secured to the center-mount brackets. The center-mounted position moves the center of gravity of the chassis closer to the vertical axis of the rack posts, which adds to the security and stability of the rack installation.
You mount the chassis in the equipment rack by first raising the chassis to the correct height, setting it in place on the rack-mounting platform (provided), and then securing it to the rack or optional center-mount brackets with screws through holes in the rack-mounting flanges on each side of the chassis. To accommodate racks with different hole patterns in their mounting flanges, the chassis rack-mounting flanges have five groups of eight oblong screw holes. (See Figure 3-13.) The mounting holes in the chassis flanges are spaced so that one mounting hole in each hole group aligns with a mounting hole in the rack or optional center-mount bracket. By using the corresponding mounting hole (in the same group) on the opposite side of the chassis, you can level the chassis in the rack.
| Warning To prevent bodily injury when mounting or servicing this unit in a rack, you must take special precautions to ensure that the router and rack remain stable. |
This section contains the following procedures:
Before you begin the process of installing the Cisco 12016 GSR chassis in the equipment rack, measure the space between the vertical mounting flanges on your rack to verify that the rack conforms to the measurements shown in Figure 3-14.
If you plan to install the Cisco 12016 GSR in the center-mount position, you must first install the center-mount brackets on the equipment rack rails, then secure the chassis to the center-mount brackets. If you do not plan to use the optional center-mount brackets, proceed directly to the "Installing the Chassis in the Rack" section.
The optional center-mount bracket installation kit ships in an accessories box included in the GSR shipping container. The installation kit should include the following pieces:
If any parts are missing, contact a Cisco service representative for assistance.
You need the following items to install the optional center-mount rack-mounting installation kit:
Figure 3-16 shows how to position and install the optional center-mount rack-mounting bracket for the right side of the chassis and rack. The brackets must be installed on the rack relative to the height of the bottom group of rack-mounting holes on the chassis when the chassis is supported by the rack-mounting platform installed in the bottom of the rack. The bottom hole on the center-mount rack-mounting bracket must align with a hole on the rack that is a minimum of 14 in (35.6 cm), above the rack-mounting platform, measured from the top surface of the rack-mounting platform to the center of the hole.
To install center-mount rack-mounting brackets, use Figure 3-16 as a reference and follow these steps:
Step 1 Measure 14 in (35.6 cm) from the top surface of the rack-mounting platform to the center of a hole on the right mounting rail on the rack and mark that hole.
Step 2 Measure and mark the hole at the same height on the left rack post.
Step 3 Measure the distance, hole center to hole center, between the two holes you marked. The distance must be 18.31 inches ± 0.06 inches (46.50 cm ± 0.15 cm).
Step 4 Measure the space between the inner edges of the left front and right front mounting rails on the equipment rack to verify that the opening is at least 17.50 in (44.45 cm). The chassis is 17.25 in (43.8 cm) wide and must fit between the mounting posts on the rack.
Step 5 Repeat Step 3 and Step 4 for pairs of holes near the middle and top of the rack to ensure that the rack posts are parallel.
Step 6 Hold the right bracket against the right mounting rail on the rack and align the bottom screw hole in the bracket with the marked screw hole near the bottom of the mounting rail on the rack.
Step 7 While supporting the bracket against the mounting rail with one hand, use the other hand to insert a screw through a hole in the bottom hole group in the bracket that aligns with a hole on the mounting rail on the rack. (See Figure 3-16.) Use your fingers to tighten the screw.
Step 8 Insert a second screw in the top hole group in the bracket and use your fingers to tighten the screw.
Step 9 Repeat Step 8 for the three middle hole groups in the bracket.
Step 10 Use a screwdriver to tighten the five screws.
Step 11 Measure and mark the location for the left bracket so that it is at the same height as the right bracket.
Step 12 Repeat Step 7 through Step 10 to install the left bracket.
Step 13 Use a level or measuring tape to ensure the tops of the two brackets are level in the rack.
Step 14 Measure the horizontal distance between the inner edges of the bracket flanges that face the chassis. The distance must be greater than 17.25 in (43.8 cm) wide for the chassis to clear the brackets.
Step 15 Adjust the width between the brackets and use the screwdriver to tighten the screws to secure the brackets against the mounting rails on the rack posts.
You have completed the procedure to install the center-mount rack-mounting brackets on the equipment rack. To install the chassis in the rack, proceed to the "Installing the Chassis in the Rack" section.
This section contains the following procedures:
When you have verified that the rack is ready to receive the chassis, you can proceed with the first phase of the chassis installation process: installing the chassis rack-mounting platform. (See Figure 3-17.) The chassis rack-mounting platform ships with the Cisco 12016 GSR.
The rack-mounting platform is a sheet-metal platform that is 17.25 in (43.82 cm) wide and 22.75 in (57.59 cm) deep. Its height is adjustable from a minimum height of approximately 5.25 in (13.34 cm) to a maximum height of approximately 8.00 in (20.32 cm). For telco-style racks, the bottom edge of the platform can be raised to approximately 6.00 in (15.24 cm) to clear the cross members at the bottom of the rack. The platform is installed at the bottom of the empty rack and acts as a permanent support platform for the chassis. It can be installed in either the front-mounted position or the center-mounted position, to match the installed position of the chassis.
To install the chassis rack-mounting platform in the rack, use Figure 3-17 as a reference and follow these steps:
Step 1 Remove the platform from the accessory box.
Step 2 To adjust the height of the platform to match the required rack-mounting height for the chassis, follow these steps:
(a) Use your fingers or a wrench to turn the screw on each of the adjustable feet to approximately the required platform height.
(b) Place the platform in the rack and use a level to determine whether the platform clears any rack cross-members, and is level from side-to-side and front-to-back.
(c) Adjust the feet until the platform clears any obstacles and is level at the required platform height.
Step 3 Determine whether the platform is to be installed in the front-mounted position or in the center-mounted position, and adjust the positioning brackets on the platform. Use Figure 3-17 as a reference and follow these steps:
(a) Locate the hole on the side of the platform that corresponds with the front-mounted or center-mounted position of the table.
(b) Align the side of the bracket with the round hole over the hole of the side of the platform, insert a screw and use your fingers to loosely tighten it.
Repeat these steps to attach a bracket in the same position on the other side of the platform.
Step 4 Align the platform between the rack posts and set it in position so that the sides of the positioning brackets with the oblong holes are flush against the rack-mounting flanges.
Step 5 To secure the platform to the rack, follow these steps:
(a) Locate an open screw hole through the oblong hole in the bracket, then insert a screw and use your fingers to loosely tighten it.
(b) On the other side of the platform, locate an open screw hole through the oblong hole in the bracket, then insert a screw and use your fingers to loosely tighten it.
(c) Verify that the platform is level and seated squarely against the rack, then tighten all four screws.
When the chassis rack-mounting platform has been installed, you can proceed with the task of moving the chassis to the site of the rack.
After the chassis and scissor-jack platform have been removed from the shipping pallet as one piece, the chassis and scissor-jack platform must be shifted onto an appropriate safety hand truck, secured, then carefully moved to the rack site.
To shift the chassis onto a safety hand truck and move it, follow these steps:
Step 1 With one person holding the chassis stable from one side, approach the chassis with the lifting blade of the hand truck from the opposite side.
| Warning Do not attempt to lift the chassis with the handles on the back and sides of the chassis. These handles are not designed to support the weight of the chassis, and should be used only to steady and guide the chassis while it is being inserted into or removed from an equipment rack. To reduce the risk of damage to the chassis and serious bodily injury, do not use these handles to lift or support the chassis. |
Step 2 Tilt the chassis slightly to insert the lifting blade of the hand truck under the bottom of the chassis.
Step 3 Verify that the side of the chassis is flush against the back of the hand truck,
Step 4 Wrap the hand truck's web security strap around the chassis, carefully avoiding any area on the front of the chassis containing any exposed components that might be broken, then lightly but firmly tighten the strap and lock it to secure the chassis to the hand truck.
Step 5 Extend and lock the safety outrigger wheels that hold the hand truck and chassis at a safe angle.
Step 6 While one person holds the base of the chassis to prevent it from shifting, have the second person slowly tilt the hand truck and chassis until the weight is taken up by the safety outrigger wheels.
Step 7 Move the chassis by having one person at the low end of the chassis to guide it around any obstacles, while the second person pushes slowly and carefully from the high end of the hand truck.
Step 8 When the chassis and scissor-jack platform have been positioned in front of the rack, slowly and carefully tilt the chassis upright until it stands on the scissor-jack platform, then remove it from the hand truck.
Step 9 With one person on either side of the chassis, rotate the chassis and scissor-jack platform so that the back panel of the chassis faces the rack opening.
Step 10 Move the chassis and scissor-jack platform so that the back panel of the chassis is aligned with the rack-mounting platform in the rack, and sitting just in front of it. (See Figure 3-18.)
When the chassis and scissor-jack platform have been positioned in front of the rack, with the back of the chassis facing the opening between the rack posts, you must raise the scissor-jack platform to the same height as the rack-mounting platform in the rack.
To insert the chassis into the rack, follow these steps:
Step 1 With one person positioned on the side of the chassis to prevent it from tipping, use the 3/4-in (19-mm) socket and ratchet wrench to turn the scissor-jack screw counterclockwise slowly and expand the scissor-jack platform to raise the chassis to the required installation insertion height. (See Figure 3-19.)
Step 2 Remove the four bolts and chassis anchor clips that secure the base of the chassis to the scissor-jack platform. (See Figure 3-20.)
| Warning Do not attempt to lift the chassis with the handles on the back and sides of the chassis. These handles are not designed to support the weight of the chassis, and should be used only to steady and guide the chassis while it is being inserted into or removed from an equipment rack. To reduce the risk of damage to the chassis and serious bodily injury, do not use these handles to lift or support the chassis. |
Step 3 Use the handle on the back panel of the chassis to pull the GSR carefully off of the scissor-jack platform and onto the rack-mounting platform in the rack while a second person pushes from the front of the chassis. (See Figure 3-21.)
Step 4 Push the GSR into the rack until the chassis rack-mounting flanges are flush against the mounting flanges on the rack (or the optional center-mount brackets, if installed).
The weight of the GSR is now supported by the rack-mounting platform.
Step 5 Remove the scissor-jack platform and set it safely aside.
Step 6 Look at the bottom group of mounting holes (group A) on the chassis. (See Figure 3-13.) Identify one of the holes in group A that aligns with a mounting hole on the mounting flanges of the rack.
Step 7 Hold the GSR in position against the mounting flanges on the rack and have a second person insert and loosely tighten one of the mounting screws provided.
Step 8 Go to the other side of the chassis and adjust the position of the chassis so that the same mounting hole in the bottom group of mounting holes (group A) is aligned with a hole in the mounting flange on the rack.
Step 9 Hold the GSR in position against the mounting flanges on the rack and have a second person insert and loosely tighten one of the mounting screws provided.
Repeat Step 6 through Step 9 for mounting hole groups B through E.
Step 10 Level the chassis as required, and then secure the chassis to the equipment rack by tightening all ten screws (five on each side of the chassis).
Before you connect power to the Cisco 12016 GSR or turn on power for the first time, we strongly recommend that you connect the central office ground system or interior equipment grounding system to the supplemental bonding and grounding receptacles on the Cisco 12016 GSR. Two receptacles are located on the front flanges of the chassis, near the lower corners of the switch fabric card cage (see Figure 3-22) and two receptacles are located on top of the power interface panel on the back of the chassis (see Figure 3-23). Each bonding and grounding receptacle consists of a round bolt hole and an elongated bolt hole, surrounded by an area of bare metal.
For more information on the bonding and grounding cable and connector requirements, refer to the"Supplemental Unit Bonding and Grounding Guidelines" section in "Preparing for Installation."
To attach a bonding and grounding cable lug to a bonding and grounding receptacle on the router, use Figure 3-22 and Figure 3-23 as references and follow these steps:
Step 1 Locate the Cisco 12016 GSR bonding and grounding receptacles you plan to use.
Step 2 Position the bonding and grounding cable lug over the bonding and grounding receptacle holes on the chassis.
Step 3 Insert the two M6 bolts through the holes in the cable lug and chassis, and then install the locking washers and nuts.
Step 4 Ensure that the bonding and grounding cable does not interfere with other router hardware, and then tighten the nuts and bolts to secure the bonding and grounding cable lug to the chassis.
Step 5 Prepare the other end of the grounding wire and connect it to the appropriate grounding point at your site to ensure an adequate earth ground.
Repeat Step 2 through Step 5 for the second bonding and grounding connection (if required).
To attach the vertical cable-management troughs, use Figure 3-24 as a reference and follow these steps:
Step 1 Align the trough so that the access gate opens toward the front of the chassis.
Step 2 Align the screw holes on the inside panel of the trough with the standoffs in the chassis rack-mounting flange near the upper horizontal cable-management tray.
Step 3 Use your fingers to insert screws into the two holes and screw them in to hold the tough in place.
Step 4 Insert a Phillips screwdriver through the access holes in the outer panel of the trough and loosely tighten the two screws.
Step 5 Insert and start screws in the middle two standoffs and the bottom two standoffs.
Step 6 Check the alignment of the trough on all six holes, then use the Phillips screwdriver to tighten all six screws.
Repeat Step 1 through Step 6 for the remaining trough.
If you removed any components to reduce the weight of the chassis before reinstalling it in the rack, you must now reinstall all of the components you removed earlier. This section describes how to reinstall the blower modules, the cards in the card cages, the power input modules, and the front covers. It also describes how to reconnect cables to the line cards, the GRP, and the alarm card. The procedure for reinstalling the power modules is described in the "Reinstalling Power Modules" section.
Procedures in the following sections describe the steps for reinstalling the router components:
| Caution The blower module weighs 20.5 lb (9.3 kg). Use two hands when handling a blower module. |
To reinstall a blower module in the chassis, use Figure 3-25 as a reference and follow these steps:
Step 1 Attach an ESD-preventive wrist strap to your wrist and connect the leash to one of the ESD connection sockets on the front of the chassis or to a bare metal surface on the chassis.
Step 2 Using two hands to support the blower module, position it in front of the blower module bay so that the blower module connector that is recessed into the back of the blower module is aligned with the connector mounted in the back corner of the blower module bay.
Step 3 Slide the blower module on the rails into the blower module bay. Stop when the blower module makes contact with the chassis connector in the back of the blower module bay.
| Caution To prevent damaging the chassis connector, do not use excessive force when inserting a blower module into its bay. |
Step 4 Firmly push on the blower module handle to seat the blower module connector in the chassis connector. (When completely seated, the blower module faceplate flanges make contact with the front of the chassis.)
Step 5 Tighten the two captive screws on the blower module faceplate.
Step 6 Position the front cover of the blower module over the four ball stud sockets around the blower module bay and power shelf.
Step 7 Push firmly on the front cover to snap the front cover into the four ball stud sockets.
Repeat these steps for the other blower module.
After you rack-mount the chassis, you must reinstall any cards that you chose to remove to reduce the weight of the chassis. This section describes how to reinstall the cards in the upper, switch fabric, and lower card cages.
This section contains the following procedures:
Install the clock and scheduler cards in the two far left slots of the switch fabric card cage (labeled CSC0 and CSC1). Install the switch fabric cards in the three far right slots (labeled SFC0, SFC1, and SFC2).
To reinstall the clock and scheduler cards and switch fabric cards in the switch fabric card cage, follow these steps:
Step 1 Attach an ESD-preventive wrist strap to your wrist and connect the leash to one of the ESD sockets on the front of the chassis or to a bare metal surface.
Step 2 To gain access to the switch fabric card cage, loosen the four captive screws on the air filter door and swing the door down, away from the fabric card cage. (See Figure 3-11.)
Step 3 Remove a card from its antistatic sack or ESD-preventive container.
Step 4 Determine the assigned card slot for the card by checking the label attached to the edge of the card carrier (near the bottom ejector lever). Clock and scheduler cards are labeled CSC and are installed in the two far left slots); switch fabric cards are labeled SFC and are installed in the three far right slots.
Step 5 Grasp the card carrier handle with one hand and place your other hand under the carrier to support and guide it into the correct slot. Slide the card halfway into the slot. Avoid touching the card circuitry or any connectors.
Step 6 Pivot both card ejector levers so the openings on the card ejector cams at the top and bottom of the card pass over the tabs on each side of the card cage slot.
| Caution Verify that the openings on the card ejector cams pass over the tabs; otherwise, one or both ejector levers might bind when you attempt to close the ejector levers, damaging or breaking one or both ejector levers. |
Step 7 Continue sliding the card into the card cage slot until the openings on the card ejector cams engage the tabs on each side of the card cage slot.
Step 8 To seat the card in the backplane connector, grasp both card ejector levers and pivot them inward toward the middle of the card carrier until they are flush against the front edge of the card carrier.
Repeat Step 3 through Step 8 for the rest of the cards in the switch fabric card cage, then proceed to Step 9.
Step 9 Pivot the air filter door up so that it is aligned with the opening of the switch fabric card cage and the four guide pins are inserted in the corresponding holes on each side of the switch fabric card cage.
Step 10 Push firmly on the air filter door until it is seated in the opening of the switch fabric card cage, then tighten the four captive screws.
| Caution The air filter door must be closed and secured at all times to maintain correct EMI performance. |
Before you begin reinstalling cards in the upper card cage, identify slot assignments by referring to the written list you prepared when you removed the cards.
To reinstall a card in the upper card cage, follow these steps:
Step 1 Attach an ESD-preventive wrist strap to your wrist and connect the leash to one of the ESD connection sockets on the front of the chassis or to a bare metal surface on the chassis.
Step 2 Remove a card from its antistatic sack or ESD-preventive container.
Step 3 Starting from the right side of the upper card cage, refer to your list of card slots to determine the assigned slot for the card.
Step 4 Grasp the front edge of the metal card carrier with one hand, and place your other hand under the carrier to support and guide it into the card cage slot.
Step 5 Carefully slide the card carrier into the slot until the ejector levers make contact with the front of the card cage, then stop.
Step 6 Grasp the two card ejector levers and pivot them toward each other until they are perpendicular to the card faceplate to seat the card in the backplane connector.
Step 7 Tighten the captive screws at the top and bottom of the card faceplate.
Repeat Step 2 through Step 7 for the rest of the cards in the upper card cage.
| Caution Any unoccupied card slot in the upper or lower card cages must have a blank filler panel installed for electromagnetic compatibility (EMC) and to ensure proper air flow through the chassis. When the faceplate of a line card does not completely fill the card slot opening, a narrow card filler panel must be installed for electromagnetic compatibility (EMC) and to ensure proper air flow through the chassis. |
Before you begin reinstalling cards in the lower card cage, identify slot assignments by referring to the written list you prepared when you removed the cards.
Except for the head-down orientation of the cards, cards are reinstalled in the lower card cage in exactly the same way as described in the "Reinstalling the Cards in the Upper Card Cage" section.
This completes the procedures for reinstalling components in the upper, switch fabric, and lower card cages.
This section describes how to route the network interface cables through the Cisco 12016 GSR cable-management system and attach the network interface cables to the line card ports.
To install the network interface cables in the Cisco 12016 GSR cable-management system and connect the network interface cables to the line cards, use Figure 3-26 as a reference and follow these steps:
Step 1 Attach an ESD-preventive wrist strap to your wrist and connect the leash to one of the ESD connection sockets on the front of the chassis or to a bare metal surface on the chassis.
Step 2 Proceeding from left to right across the card cage, check your written list of network interface cable connections and identify the interface cables that attach to the first line card.
Step 3 One network interface cable at a time, carefully route the identified interface cable across the horizontal cable-management tray to the cable tray finger for the slot of the assigned line card. (See Figure 3-26a.)
Step 4 Proceeding from the port farthest from the cable-management tray (on line cards with multiple ports only), identify the cable that connects to that port.
Step 5 If the card uses copper cables, skip this step and proceed to Step 6. If the card uses fiber-optic cables, install plastic bend-radius clips on the strain-relief ferrule on the connector. Use Figure 3-26a as a reference and follow these steps:
(a) Get the bag of bend-radius clips (Cisco part number 800-06119-01) from the accessories box that shipped with your GSR.
(b) Orient the bend-radius clip so that the large end of the clip is toward the cable connector and insert the fiber-optic cable into the opening on the bend-radius clip.
(c) Slide the bend-radius clip along the cable until it clamps around the strain-relief ferrule on the cable connector.
The curve in the bend-radius clip holds the fiber-optic cable in the appropriate entry curve for the cable connector, minimizes kinking, and protects the fiber-optic cables.
Step 6 Insert the cable connector into its assigned port.
Step 7 Proceeding from the port farthest from the cable-management tray (line cards with multiple ports only), route the cable up the channel in the line card cable-management bracket and carefully press the cable into the channel, so that it is held in place by the cable clips in the line card cable-management bracket, as shown in Figure 3-26b.
Repeat Step 2 through Step 7 for the rest of the line card network interface cables.
This section describes how to connect cables to the console and auxiliary ports (see Figure 3-26), as well as to one of the Ethernet ports on the GRP (see Figure 3-27). GRP Console and Auxiliary Port Connections
| Warning The ports labeled "Ethernet," "10BaseT," "Token Ring," "Console," and "AUX" are safety extra-low voltage (SELV) circuits. SELV circuits should only be connected to other SELV circuits. |
This section contains the following procedures:
The system console port on the GRP is an EIA/TIA-232 DCE DB-25 receptacle for connecting a data terminal, which you will need to perform the initial configuration of the router. The console port is labeled Console. See Figure 3-26 for an example of a data terminal connection.
Before connecting a terminal to the console port, check your terminal's documentation to determine the terminal's data transmission rate, in bits per second (bps). The terminal's transmission rate setting must match the default rate of the GRP console port, which is 9600 bps. Set the terminal to these operational values: 9600 bps, 8 data bits, no parity, 2 stop bits (9600 8N2).
To connect a data terminal to the GRP console port, follow these steps:
Step 1 Attach an ESD-preventive wrist strap to your wrist and connect the leash to one of the ESD connection sockets on the front of the chassis or to a bare metal surface on the chassis.
Step 2 Verify that the data terminal is turned off and disconnected from its power source.
Step 3 Attach the terminal end of the cable to the interface port on the data terminal.
Step 4 Attach the other end of the cable to the GRP console port.
The auxiliary port on the GRP is an EIA/TIA-232 DTE DB-25 plug for connecting a modem or other DCE device---such as a channel service unit/data service unit (CSU/DSU) or another router---to the Cisco 12016 GSR. The port is labeled Auxiliary. Figure 3-26 shows an example of a modem connection. The asynchronous auxiliary port supports hardware flow control and modem control.
Follow these steps to connect an asynchronous serial device to the GRP auxiliary port:
Step 1 Attach an ESD-preventive wrist strap to your wrist and to one of the ESD connection sockets on the front of the chassis or to a bare metal surface on the chassis.
Step 2 Verify that the asynchronous serial device is turned off and disconnected from its power source.
Step 3 Attach the device end of the cable to the interface port on the asynchronous serial device.
Step 4 Attach the other end of the cable to the GRP auxiliary port.
The Ethernet port on the GRP has both a media-independent interface (MII), 40-pin, D-type receptacle and a media-dependent interface (MDI) RJ-45 receptacle. (See Figure 3-27.)
The RJ-45 and MII receptacles on the GRP represent two physical connection options for only one Ethernet interface; therefore, you can use either the RJ-45 connection or the MII connection, but not both simultaneously. The RJ-45 and MII LEDs on the GRP faceplate show which Ethernet receptacle is active when the GRP is operating.
| Warning The ports labeled "Ethernet," "10BaseT," "Token Ring," "Console," and "AUX" are safety extra-low voltage (SELV) circuits. SELV circuits should only be connected to other SELV circuits. |
Use the following procedure to connect a cable to the GRP RJ-45 Ethernet receptacle:
Step 1 Attach an ESD-preventive wrist strap to your wrist and to one of the ESD connection sockets on the front of the chassis or to a bare metal surface on the chassis.
Step 2 Push the modular plug on the Category 5 UTP cable directly into the RJ-45 receptacle on the GRP. (See Figure 3-27.)
The Ethernet interface on the GRP is an end-station device, not a repeater; therefore, you must connect the GRP Ethernet interface to a repeater or hub.
| Caution To prevent problems on your router and network, do not connect RJ-45 and MII cables to the Ethernet receptacles on the GRP at the same time. The GRP can support only one Ethernet connection at a time. Use cables that comply with EIA/TIA-568 standards. For cable specifications and standards, refer to the "GRP Console and Auxiliary Port Connection Guidelines" section in "Preparing for Installation." |
Step 3 Attach the network end of your RJ-45 cable to your transceiver, switch, hub, repeater, DTE, or other external equipment. Be sure to use the appropriate strain relief on the cable connection.
The MII receptacle requires an external transceiver that permits connection to multimode fiber for 100BaseFX or 100BaseT4 physical media. Depending on the type of media you use between the MII receptacle and your switch or hub, the network side of your 100-Mbps transceiver should be appropriately equipped with ST-type connectors (for fiber-optic cables), BNC connectors, and so forth.
Use the following procedure to connect a cable to the MII Ethernet receptacle on the GRP:
Step 1 Attach an ESD-preventive wrist strap to your wrist and to one of the ESD connection sockets on the front of the chassis or to a bare metal surface on the chassis.
Step 2 Attach an MII cable directly to the MII receptacle on the GRP, or attach a 100BaseT transceiver with the media appropriate to your application to the MII receptacle on the GRP. (See Figure 3-27.)
The MII receptacle uses 2-56 screw-type locks, called jackscrews, to secure the cable or transceiver to the MII port. MII cables and transceivers have knurled thumbscrews that you fasten to the jackscrews on the MII connector and tighten with your fingers. Use the jackscrews to secure your MII cable to the MII receptacle.
| Caution To prevent problems on your router and network, do not connect RJ-45 and MII cables to the Ethernet receptacles on the GRP at the same time. The GRP can support only one Ethernet connection at a time. Use cables that comply with EIA/TIA-568 standards. For cable specifications and standards, refer to the"GRP Console and Auxiliary Port Connection Guidelines" section in "Preparing for Installation." |
Step 3 Attach the network end of your MII cable to your transceiver, switch, hub, repeater, DTE, or other external equipment. Be sure to use the appropriate strain relief on the cable connection.
The Cisco 12016 GSR alarm card has one 25-pin D-sub connector, labeled ALARM, on the alarm card faceplate. (See Figure 3-28.)
This connector can be used to connect the router to an external site alarm maintenance system so that any critical, major, and minor alarms generated by the Cisco 12016 GSR also energize alarm relays on the alarm card and activate the external site alarm. The alarm relay contacts on the alarm card consist of standard common, normally open, and normally closed relay contacts that are wired to the pins on the connector labeled ALARM.
Table 2-8 lists the pin-to-signal correspondence between the connector pins and the alarm card relay contacts. Because alarm contact cables are entirely dependent on installation site circumstances, alarm connector cables are not available from Cisco Systems. For information about alarm connector wiring requirements and the pinouts for the alarm connector interface, refer to the "Alarm Card Connection Guidelines" section in "Preparing for Installation."
| Warning The ports labeled "Ethernet," "10BaseT," "Token Ring," "Console," and "AUX" are safety extra-low voltage (SELV) circuits. SELV circuits should only be connected to other SELV circuits. |
This section describes how to connect input power to an AC-input power shelf or to a DC-input power shelf. This section contains two procedures:
Select the appropriate procedure for your router.
| Caution A Cisco 12016 GSR must be operated with all of its power modules installed at all times for electromagnetic compatibility (EMC). |
This section describes how to connect AC power cords to the AC input receptacles on the back of the AC-input power shelf (see Figure 3-29).
To connect AC source to the AC-input power supply shelf, use Figure 3-29 as a reference and follow these steps:
Step 1 Get the three AC power cords from the accessories box.
Step 2 Verify that the AC power cords shipped with the router are the correct type for your site. For more information on AC power cords, refer to the "Power Connection Guidelines" section in "Preparing for Installation."
Step 3 Beginning with the far right AC receptacle on the back of the power shelf, pull back on the power cord retention clip and insert the AC power cord appliance coupler into the AC receptacle.
Step 4 Lower the power cord retention clip onto the power cord appliance coupler to secure the power cord in the AC receptacle.
Step 5 Connect the other end of the AC power cord to the source AC receptacle.
Step 6 Route the power cord across the top of the chassis and down the side to keep it safely out of the way, in case you need to remove the back cover of the chassis.
Repeat Step 3 through Step 6 for the second and third AC power cords.
This section describes how to connect source DC power cables to the DC input terminal connections on the back of the DC-input power shelf. (See Figure 3-30.)
A Cisco 12016 GSR equipped with the DC-input power shelf requires the following cables:
The length of the cables depends on the location of your router in relation to the source of DC power. These cables and the cable lugs used to attach the cables to the router chassis are not available from Cisco Systems. They are available from any commercial cable vendor. For more information on site power and source DC cable requirements, refer to the in "Power Connection Guidelines for DC-Powered Routers" section in "Preparing for Installation."
To connect source DC to the DC-input power entry module shelf, follow these steps:
Step 1 Attach an antistatic wrist strap to your wrist and connect the leash to one of the ESD connection sockets on the front of the chassis or to a bare metal surface on the chassis.
Step 2 To remove the cover over the cable terminal studs on the back panel of the power shelf, use Figure 3-30 as a reference and follow these steps:
(a) Loosen, but do not remove, the screw that secures the cover.
(b) Slide the cover down to free the screw head, and then pull the cover away from the power entry module shelf.
(c) Set the safely cover aside.
| Warning When installing the source DC power cable leads, always make the ground connection first and disconnect the ground connection last. |
Step 3 Remove only the outer nut and locking washer from each of the threaded terminal studs on the back of the power shelf. (See Figure 3-31.)
| Caution To prevent strain on the power shelf terminal studs, allow sufficient slack in the source DC power cable leads and secure the power cable leads to the chassis. |
Step 4 Route the source DC ground cable from the right side of the chassis, across the top of the power shelf, and to the power shelf ground cable terminal studs. (See Figure 3-31.)
Step 5 Fit the holes in the ground cable lug over the ground cable terminal studs on the power shelf, replace the locking washers and nuts, and then tighten them to secure the ground cable lug.
Step 6 Route the source DC (negative) and source DC return (positive) cable leads.
If you are installing the source DC power cable leads on the terminal studs for power supplies in either bay B2 or bay B1, route the source DC power cable leads from the right side of the chassis (facing the back of the chassis), as shown in Figure 3-31.
If you are installing the source DC power cable leads on the terminal studs for power supplies in either bay A1 or bay A2, route the source DC power cable leads from the left side of the chassis (facing the back of the chassis), as shown in Figure 3-31.
Step 7 To install the power module source DC cable leads, use Figure 3-31 as a reference and follow these steps:
(a) For each power entry module cable lead pair, identify the source DC return (positive) and source DC (negative) cable leads.
(b) Select the source DC return (positive) cable lead and fit the holes in the cable lug over the source DC return (positive) terminal studs on the power shelf.
(c) Replace the washers and nuts and tighten them to secure the cable lug.
(d) Select the source DC (negative) cable lead and fit the holes in the cable lug over the source DC (negative) terminal studs on the power shelf.
(e) Replace the washers and nuts and tighten them to secure the cable lug.
Step 8 Verify that the polarity of the source DC wiring from the source DC breaker to the power shelf is correct and that the terminal connections on the power shelf are correct and tight.
Repeat Step 6 through Step 8 for the remaining source DC power cables.
Step 9 Position the power shelf terminal stud cover so that the cable openings are over the cables and the standoff keyhole is over the standoff screw on the power shelf. Slide the cover upward slightly to engage the screw head in the keyhole slot, and then secure the cover by tightening the screw.
This section contains two procedures:
Select the appropriate procedure for your router.
| Caution A Cisco 12016 GSR must be operated with all of its power modules installed at all times for electromagnetic compatibility (EMC). |
Figure 3-32 shows how to reinstall the AC-input power supplies in the power shelf.
| Caution The AC-input power supply weighs 12.7 lb (5.7 kg). Because of the weight of the power supply and the height of the power shelf, you should use two hands when handling the power supply. |
To install an AC-input power supply, use Figure 3-32 as a reference and follow these steps:
Step 1 Attach an ESD-preventive wrist strap to your wrist and connect the leash to one of the ESD connection sockets on the front of the chassis or to a bare metal surface on the chassis.
Step 2 Lift the ejector lever spring clip on the power supply and pivot the ejector lever until it is perpendicular to the power supply faceplate. (See Figure 3-32a.)
| Caution To prevent damage to the power shelf backplane connector, do not use excessive force when inserting a power supply into the bay. |
Step 3 Using two hands to support and guide the power supply, slide it into the power shelf until the connector on the back of the power supply touches the connector on the backplane of the power shelf. (See Figure 3-32b.)
Step 4 Seat the power supply in the power shelf backplane by pivoting the ejector lever to hook the slot on the floor of the power shelf and then pushing the ejector lever until it is flush with the power supply faceplate. (See Figure 3-32c.)
Repeat Step 2 through Step 4 for the remaining AC-input power supplies.
Proceed to the "Reinstalling the Chassis Front Covers" section for procedures for reinstalling the chassis front covers.
Figure 3-33 shows how to reinstall the DC-input power entry modules in the power shelf.
To install a DC-input power entry module, use Figure 3-33 as a reference and follow these steps:
Step 1 Attach an ESD-preventive wrist strap to your wrist and connect the leash to one of the ESD connection sockets on the front of the chassis or to a bare metal surface on the chassis.
Step 2 Loosen the ejector lever captive screw on the power entry module and pivot the ejector lever until it is perpendicular to the power entry module faceplate. (See Figure 3-33a.)
| Caution To prevent damage to the power shelf backplane connector, do not use excessive force when inserting a power entry module into the power shelf. |
Step 3 Using two hands to support and guide the power entry module, slide it into the power shelf until the connector on the back of the power entry module just makes contact with the connector on the backplane of the power shelf. (See Figure 3-33b.)
Step 4 Seat the power entry module in the backplane connector by pivoting the ejector lever to engage the slot in the floor of the power shelf, then pushing the ejector lever until it is flush with the power entry module faceplate. (See Figure 3-33c.)
Step 5 Tighten the captive screw on the ejector lever. (See Figure 3-33d.)
Repeat Step 2 through Step 5 for the remaining DC-input power entry modules.
Proceed to the "Reinstalling the Chassis Front Covers" section for procedures for reinstalling the chassis front covers.
Figure 3-34 shows the four removable, snap-on front covers in the correct top-to-bottom order on the front of the chassis.
To install a snap-on front cover, use Figure 3-34 as a reference and follow these steps:
Step 1 Hold the front cover by its outside edges and align the ball studs with the sockets on the front of the chassis.
Step 2 Push the front cover into the ball stud sockets until all four ball studs snap into their sockets and the front cover is flush with the front of the chassis.
Repeat Step 1 and Step 2 for the remaining front covers, if required.
This completes the hardware installation procedure for the Cisco 12016 GSR. Proceed to the next chapter, "Observing System Startup and Performing a Basic Configuration," to observe the initial router startup and perform basic configuration.
