The rack-mount kit includes the following parts:
This section describes how to rack-mount the Cisco AS5200 or the Cisco AS5300 chassis. The access server comes with 19-inch rack-mount brackets and larger brackets for use with a 23- or 24-inch rack. (See Figure 3-1.) You can also order telco rack-mount brackets (Figure 3-2) from Cisco. The telco bracket part number is: AS52/3RM-TELCO-19"=.
The following information will help you plan your equipment rack configuration:
|
Warning Before working on a chassis or working near power supplies, unplug the power cord on AC units; disconnect the power at the circuit breaker on DC units. To see translations of the warnings that appear in this publication, refer to the Regulatory Compliance and Safety Information document that accompanied this device. |
To install the chassis in a rack, attach the brackets in one of the following ways:
|
Note Although the installations show the 19-inch brackets, the procedure is the same for the larger brackets. |
After the brackets are secured to the chassis, you can rack-mount the access server. Using the screws that you provide, attach the chassis to the rack as shown in Figure 3-6 and Figure 3-7.
In a typical Cisco AS5800 rack-mount configuration, you mount both the dial shelf and the router shelf together in a rack, with the dial shelf mounted below the router shelf. We do not recommend that you separate the dial shelf from the router shelf when configuring the hardware for this system; however, a 20-foot interconnect cable is available if you need to install the router shelf in an adjacent equipment rack. If you are using AC-input power, you mount the AC-input power shelf below the dial shelf.
There is no clearance requirement for mounting the router shelf directly above the dial shelf; however, if you install anything other than a Cisco 7206 router shelf above the dial shelf, follow the appropriate clearance requirements for the unit you install.
You can stack two access servers in a single equipment rack; however, you must leave a minimum clearance of one rack unit, 1.75 inches (4.28 cm), between the two systems.
You must install the AC-input power shelf one rack unit below the dial shelf to accommodate the DC power cables, the monitor cable, the grounding cable, and the required safety cover.
|
Note One rack unit (1.75 inches or 4.4 cm) is the maximum distance between the dial shelf and the AC-input power shelf that still accommodates the required safety cover. |
Some equipment racks provide a power strip along the length of one of the mounting strips. If your rack has a power strip, consider the position of the strip when planning fastener points to ensure that you will be able to slide feature cards and dial shelf controller cards straight out of their respective slots. If the power strip does impair a rack-mount installation, remove the power strip before installing the dial shelf in the rack, then replace the power strip after the dial shelf is installed.
Figure 3-8 shows a typical 19-inch, 4-post equipment rack with a power strip along one of the back posts.
To use the rack-mounting hardware provided with your Cisco 5814 dial shelf, consider the following guidelines:
When planning your rack installation, consider the following guidelines:

Rack-mounting the Cisco AS5800 takes several steps:
The Cisco 5814 dial shelf is shipped with the blower assembly and all feature cards (trunk and modem cards) and dial shelf controller card installed in the chassis. Fully loaded, the dial shelf weighs 278 lb (126.1 kg).
Before installing the Cisco 5814 in an equipment rack, we recommend that you remove the blower assembly, feature cards, and dial shelf controller cards from the dial shelf, then reinstall them after the dial shelf is mounted in the rack. (If you are using a fork lift or other machinery to lift the dial shelf, you might want to omit this step.)
|
Caution The blower assembly weighs 27.5 lb (12.5 kg). Use two hands when removing or replacing the blower assembly. |
To remove the blower assembly, perform the following steps:
Step 2 Loosen the two captive screws on the blower assembly front panel. (See Figure 3-10.)
Step 3 Grasp the blower assembly handle with one hand and pull the blower assembly straight toward you about halfway out of the slot. (See Figure 3-10.)
Step 4 Place your other hand under the blower assembly as it extends from the dial shelf chassis.
Step 5 Slowly pull the blower assembly all the way out of the slot and set it aside until you are ready to reinstall it.
To remove the feature cards and dial shelf controller cards, perform the following steps:
|
Caution Trunk cards and modem cards weigh 8 lb (3.3 kg) each. Dial shelf controller cards weigh 8.5 lb (3.8 kg) each. Use two hands when removing or replacing cards in the dial shelf. |
Step 2 Attach an ESD-preventive wrist strap between you and an unpainted chassis surface.
|
Caution To prevent ESD damage, handle trunk cards by the carrier edges only, and use an ESD-preventive wrist strap or other grounding device. |
Step 3 Loosen the panel fasteners at the top and bottom of the card front panel using a number 2 Phillips screwdriver.
Step 4 Pull either the upper or lower ejector lever away from the card front panel to disengage the card from the backplane connector, as shown in Figure 3-11.
|
Caution Always use the ejector levers when disengaging or seating the trunk cards, modem cards, or dial shelf controller cards in the dial shelf backplane. Failure to do so can cause erroneous system error messages, indicating a card failure. However, do not use the ejector levers to lift or support the weight of the cards. |
Step 5 Grasp the ejector levers and pull the card partially out of the dial shelf slot until you can grasp the card front panel with one hand. Place your other hand under the card to balance the weight of the card as you pull it out of the slot. (See Figure 3-12.)
Step 6 Pull the card straight out of the slot. Avoid touching the circuitry or any connector pins.
Step 7 Place the removed card on an antistatic mat or foam pad until you are ready to reinstall it in the chassis.
Step 8 Repeat Step 3 through Step 7 for all remaining cards in the dial shelf chassis.
You are now ready to install the rack-mount brackets on the chassis. Proceed to the following section "Installing the Rack-Mount Brackets on the Cisco AS5800 Chassis."
Bracket placement depends on the type of rack you use to install your Cisco AS5800 access server. This section describes both a 4-post rack installation and a telco rack installation.
Threaded holes on the chassis sides are strategically located to position and mount bracket hardware. The dial shelf also has an affixed mounting flange in front for flush-front mounting. If you are mounting the dial shelf in a 4-post rack, you have the option of using two brackets (one on each side) placed toward the lower rear of the chassis (see Figure 3-13, position d) to support the chassis in the back. If you are mounting the dial shelf in a telco rack, you must offset the dial shelf 5 inches beyond the rack center post and use six brackets (three on each side) at positions a, b, and c, as shown in Figure 3-13.
If you are installing your Cisco AS5800 access server in a telco rack, proceed to the next section, "Mounting Forward Brackets for an Offset Telco Rack Installation."
If you are installing your Cisco AS5800 access server in a 4-post rack, you do not need to install brackets on the chassis front; use the permanent metal flanges on the chassis front to install the dial shelf in the rack. (See Figure 3-13.) Proceed to the "Installing the Dial Shelf in the Rack" section.
To install the forward rack-mount brackets on the dial shelf for an offset telco rack-mount configuration, perform the following steps:
Step 2 Align one rack-mount bracket with a set of forward-upper threaded holes (Figure 3-13, position a) in the orientation shown in Figure 3-14, position a.
Step 3 Thread two M5 x 10mm Phillips, flathead screws through the bracket and into the side of the chassis. Tighten the screws using a number 2 Phillips screwdriver.
Step 4 Align the second rack-mount bracket with the forward-lower position threaded holes in the orientation shown in Figure 3-14, position b.
Step 5 Fasten the bracket to the chassis using two screws, as described in Step 3.
Step 6 Repeat Step 1 through Step 5 to mount the two forward brackets on the left side of the chassis.
You are now ready to install the dial shelf in the telco rack. Proceed to the next section, "Installing the Dial Shelf in the Rack."
Use the slotted mounting screws provided to secure the rack-mount brackets to the posts or mounting strips in the rack. Because the brackets support the entire weight of the chassis, be sure to use at least two slotted screws per bracket.
To install the dial shelf chassis in the rack, perform the following steps:
|
Caution To prevent injury, review the safety precautions, "Dial Shelf Safety Precautions" section, before installing the dial shelf in the rack. |
Step 2 Attach one support bracket to each front post or mounting strip using the provided slotted screws and a 1/4-inch, flat-blade screwdriver. Ensure that the support brackets are level. (See Figure 3-15 and Figure 3-16.)
Step 3 Position the dial shelf chassis in front of the rack.
|
Warning Two people are required to lift the chassis. Use the handles on the chassis sides. To prevent injury, keep your back straight and lift with your legs, not your back. To prevent damage to the chassis and components, never attempt to lift the chassis with the handles on the power supplies, the filter module, or on the blower assembly. These handles are not designed to support the weight of the chassis. To see translations of the warnings that appear in this publication, refer to the Regulatory Compliance and Safety Information document that accompanied this device. |
Step 4 Lift and slide the dial shelf chassis into the rack, resting it on the two support brackets. Push the dial shelf back until the forward brackets or chassis mounting flanges meet the mounting strips or posts on both sides of the equipment rack.
|
Note The brackets will support the chassis until you complete the installation. Removing the support brackets is optional. If you leave the brackets installed, they can be used as spacers between the dial shelf and the optional AC-input power shelf. |
Step 5 Insert the 10-32 x 3/8-inch slotted screws (two screws per bracket) through the brackets (or chassis mounting flange) and into the mounting strip. Tighten all the screws using a 1/4-inch flat-blade screwdriver.
|
Note Because the brackets support the weight of the entire chassis, be sure to use at least two slotted screws per bracket. |
To complete the dial shelf rack installation, you must mount the rear set of brackets to the chassis. Proceed to the section "Mounting the Rear Brackets."
This section explains how to mount the rear brackets for telco and 4-post rack installations.
|
Note You must mount the rear brackets after you install the dial shelf in the rack. |
For a telco rack-mount installation, mount the rear bracket as follows:
Step 2 Thread two M5 x 10mm Phillips, flathead screws through the bracket and into the side of the chassis.
Step 3 Tighten the screws using a number 2 Phillips screwdriver.
Step 4 Repeat Step 1 through Step 3 to mount the rear bracket on the other side of the chassis.
Step 5 Insert the 10-32 x 3/8-inch slotted screws (two screws per bracket) through the brackets and into the equipment rack-mounting strip. Tighten all the screws using a 1/4-inch flat-blade screwdriver.
Figure 3-15 shows a dial shelf installed in a telco rack. Bracket positions labeled "a," "b," and "c" correspond to Figure 3-14, positions a, b, and c.
This completes the dial shelf rack-mounting procedures for a telco rack. Proceed to the "Replacing the Dial Shelf Components" section.
For a 4-post rack-mount installation, mount the optional rear brackets to the sides of the chassis as follows:
Step 2 Thread two M5 x 10mm Phillips, flathead screws through the bracket and into the side of the chassis.
Step 3 Tighten the screws using a number 2 Phillips screwdriver.
Step 4 Repeat Step 1 through Step 3 to mount the rear bracket on the other side of the chassis.
Step 5 Position the rear equipment rack-mounting strips flush with the rear rack-mounting brackets of the dial shelf chassis and secure the strips in the equipment rack.
Step 6 Insert the 10-32 x 3/8-inch slotted screws (two screws per bracket) through the brackets and into the equipment rack-mounting strip. Tighten all screws using a 1/4-inch flat-blade screwdriver.
This completes the dial shelf rack-mounting procedures for a 4-post rack. Proceed to the next section, "Replacing the Dial Shelf Components."
This section contains instructions for replacing the blower assembly and the dial shelf components.
Replace the blower module in the dial shelf as follows:
|
Caution The blower assembly weighs 27.5 lb (12.5 kg). Use two hands when removing or replacing the blower assembly. |
Step 2 Align the blower assembly with the chassis opening and slide the blower assembly into the dial shelf chassis.
Step 3 Push the blower assembly all the way into the dial shelf chassis until the connector on the rear of the blower assembly is fully seated in the chassis.
Step 4 Tighten the two captive thumbscrews on the blower assembly front panel.
|
Note All electrical connections are fully operative when the connectors mate. |
Replace the trunk cards, modem cards, and dial shelf controller cards in the chassis as follows:
 |
TimeSaver Your dial shelf arrived with trunk cards, modem cards, and dial shelf controller cards installed in the proper slots. You can refer to your original configuration notes when replacing cards in the dial shelf chassis. |
If you did not note the original card configuration, replace the cards in the dial shelf slots, which are numbered from left to right, as follows:
|
Caution Trunk cards and modem cards weigh 8 lb (3.6 kg) each. Dial shelf controller cards weigh 8.5 lb (3.8 kg) each. Use two hands when removing or replacing cards in the dial shelf. |
|
Caution To prevent ESD damage, handle trunk cards by the carrier edges only, and use an ESD-preventive wrist strap or other grounding device. |
Step 2 Carefully align the card carrier guides with top and bottom grooves in the dial shelf slot. Avoid touching the circuitry or any connector pins.
Step 3 Slide the carrier into the dial shelf slot until the ejector levers make contact with the chassis frame. (See Figure 3-11.)
Step 4 Seat the card in the backplane by pushing the card firmly until the ejector levers fold in toward the trunk card front panel, and the front panel is flush with the chassis frame.
|
Caution Always use the ejector levers when disengaging or seating trunk cards, modem cards, or dial shelf controller cards in the dial shelf. Failure to do so can cause erroneous system error messages, indicating a card failure. However, do not use the ejector levers to lift or support the weight of the cards. |
Step 5 Tighten the panel fasteners on the top and bottom of the card front panel using a number 2 Phillips screwdriver. This prevents the card from becoming partially dislodged from the backplane and ensures proper EMI shielding.
|
Caution Always tighten the panel fasteners on trunk cards, modem cards, and dial shelf controller cards. These fasteners prevent accidental removal and provide proper grounding for the system. |
Step 6 Repeat Step 3 through Step 5 for all remaining cards you want to install.
|
Caution To avoid erroneous failure messages, remove or insert only one trunk card at a time. Also, after inserting or removing a trunk card, allow at least 15 seconds before removing or inserting another trunk card so that the system can reinitialize and note the current configuration of all interfaces. |
Step 7 Install a blank filler card (DS58-BLANK=) in all empty dial shelf card slots to keep the chassis dust free and to maintain proper airflow.
|
Caution To prevent the overheating of internal components, always install blank filler cards in empty dial shelf slots to maintain the proper flow of cooling air across the cards. |
The Cisco 5814 dial shelf ships with a double ground lug attached to two pemnuts in the upper-left corner on the rear of the dial shelf chassis. To ground the dial shelf, perform the following steps:
|
Warning When installing the unit, the ground connection must always be made first and disconnected last. To see translations of the warnings that appear in this publication, refer to the Regulatory Compliance and Safety Information document that accompanied this device. |
Step 2 Attach the double ground lug to your own 6-gauge ground wire.
Step 3 Fasten the ground lug to the dial shelf chassis using the screws you removed.
This completes the procedure for installing the dial shelf in a rack. You are now ready to install the Cisco 7206 router shelf in the equipment rack.
The router shelf is intended to be rack-mounted above the dial-shelf in the same equipment rack; however, you can rack-mount the router shelf in an adjacent rack. The interconnect cable supplied by Cisco, which provides the physical connection between the router shelf and the dial shelf, is available in a 6-ft (6.09-m) or 20-ft (1.83-m) length.
There is no clearance requirement for mounting the router shelf directly above the dial shelf. Use the rack-mounting brackets and cable-management kit that shipped with the Cisco 7206 router shelf to install the router shelf in the rack.
To install the Cisco 7206 router shelf, refer to the chapter "Installing the Router" in the Cisco 7206 Installation and Configuration Guide that shipped with your Cisco 7206 router shelf. After you complete the router shelf installation, you are ready to connect the cables. Proceed to the next section, "Connecting the Dial Shelf to the Router Shelf."
The Cisco 7206 router shelf contains a dial shelf interconnect port adapter with one RJ-45 receptacle, which is used to connect the router shelf to the Cisco 5814 dial shelf. The interconnect port adapter installs in any 7206 router shelf port adapter slot and connects directly to the Cisco 5814 dial shelf controller card using one, full-duplex cable.
The cable used for this connection is available only from Cisco Systems; it is customized with shielding to decrease electromagnetic interference (EMI) emissions, and jackscrews to secure the connection. You must use this specially designed cable that shipped with your interconnect port adapter to connect the dial shelf to the router shelf.

Warning This product is intended for installation in restricted access areas and is approved for connection using 12 or 14 AWG copper conductors only. The installation must comply with all applicable codes. To see translations of the warnings that appear in this publication, refer to the Regulatory Compliance and Safety Information document that accompanied this device. |
See Figure 3-37 and perform the following steps to wire the terminal block:
|
Note For central office installations, it is recommended to use a 6 AWG green ground wire with one end connected to reliable earth. The other end of the wire should be crimped onto the double-hole lug provided in the installation pack. The lug should be secured to the mating holes on either side of the chassis with the two screws included in the accessory pack. |
|
Warning Figure 3-37 shows the DC power supply terminal block. Wire the DC power supply using the appropriate wire terminations at the wiring end, as illustrated. The proper wiring sequence is ground-to-ground, positive-to-positive, and negative-to-negative. Note that the ground wire should always be connected first and disconnected last. To see translations of the warnings that appear in this publication, refer to the Regulatory Compliance and Safety Information document that accompanied this device. |
|
Caution In a DC power supply installation, do not connect the -48 VDC return to chassis ground at the Cisco AS5300. A single-point ground is recommended at the power distribution rack. |
Step 2 Strip off one-quarter of an inch (1/4 in. [0.625 cm]) of insulation on the safety ground, +48 VDC, and -48 VDC input wires.
Step 3 Install the safety ground (green wire) into the terminal block ground connector and tighten the locking screw. Ensure that no bare wire is exposed.
|
Caution Do not overtorque the terminal block contact screws. The recommended torque is 8.2 ± 0.4 in.-lb. |
Step 4 Insert the +48 VDC wire into the terminal block positive connector (+) and tighten the locking screw. Ensure that no bare wire is exposed.
Step 5 Insert the -48 VDC wire into the terminal block negative connector (-) and tighten the locking screw. Ensure that no bare wire is exposed.
Step 6 Secure the power supply cord to the cable strain-relief clamps on the DC power supply with cable ties.
|
Warning After wiring the DC power supply, remove the tape from the circuit breaker switch handle and reinstate power by moving the handle of the circuit breaker to the ON position. To see translations of the warnings that appear in this publication, refer to the Regulatory Compliance and Safety Information document that accompanied this device. |
Step 7 Press the power switch to the ON position.
Verify that the internal power supply fan is on.
This section explains how to connect to a DC power source and power on the system. If you are using AC-input power, refer to the "Connecting to an AC Power Source" section for AC-to-DC power cabling and powering on instructions.
|
Warning Before working on a chassis or working near power supplies, unplug the power cord on AC units; disconnect the power at the circuit breaker on DC units. To see translations of the warnings that appear in this publication, refer to the Regulatory Compliance and Safety Information document that accompanied this device. |
|
Warning Secure all power cabling when installing this unit to avoid disturbing field-wiring connections. To see translations of the warnings that appear in this publication, refer to the Regulatory Compliance and Safety Information document that accompanied this device. |
|
Warning When installing the unit, the ground connection must always be made first and disconnected last. To see translations of the warnings that appear in this publication, refer to the Regulatory Compliance and Safety Information document that accompanied this device. |
If your site has access to a DC power source, you need to provide your own DC power cables. In the United States use 6 AWG stranded or solid copper wire; elsewhere use 16 mm2 solid or 10 mm2 stranded copper wire.
Complete the following cabling instructions:
Step 2 Strip the DC power cable of its outer insulation to expose about 1/2 inch (1.27 cm) of the copper wires.
Step 3 Connect the power cable stripped wires to the DC terminal block on the PEM and securely tighten the terminal block connector screws. (See Figure 3-38.)
Step 4 Connect the other end of your DC power cables to your DC power source.
Step 5 Repeat Step 1 through Step 4 to connect your DC power cables to the second PEM.
|
Note If the two DC conductors entering the PEM terminal block are reversed, a yellow warning LED on the PEM illuminates to indicate a miswire. No damage will occur; however, you must power off the power at the source and reverse the connections. |
If your site has access only to an AC power source, you need to install the optional AC-input power shelf to convert to DC-input power.
AC-input power is accepted by a separate, self-contained AC-input power shelf, that converts AC-input power to DC-output for use by the DC-powered dial shelf. The AC-input to DC-output connection supplies -48V DC-output power to the dial shelf PEMs by two AC-to-DC power cables (DS5800-CAB-ACDC=) supplied by Cisco.
|
Note See the "Supplying Power to a Cisco AS5800" section for detailed instructions on connecting the dial shelf to the AC-input power shelf and connecting to an AC power source. |
The Cisco 5814 dial shelf ships with a double ground lug attached to two pemnuts in the upper-left corner on the rear of the dial shelf chassis. To ground the dial shelf, perform the following steps:
|
Warning When installing the unit, the ground connection must always be made first and disconnected last. To see translations of the warnings that appear in this publication, refer to the Regulatory Compliance and Safety Information document that accompanied this device. |
Step 2 Attach the double ground lug to your own 6-gauge ground wire.
Step 3 Fasten the ground lug to the dial shelf chassis using the screws you removed.
This completes the procedures for installing and cabling your Cisco AS5800.
