Cisco Product Number: PWR-GSR16-AC4-SH(=) (spare shelf), PWR-GSR16/AC-UPGR (Upgrade Kit)
This publication describes how to remove a standard single-level AC-input power shelf from the Cisco 12016 Gigabit Switch Router (GSR) and replace it with the optional two-level AC-input power shelf. This publication also includes instructions for verifying the operation of the system after you perform the power shelf upgrade.
The following sections are included in this publication:
Your router and the Cisco IOS software running on it contains extensive features and functionality, which are documented in the following resources:
The standard Cisco 12016 GSR AC-input power subsystem consists of a one-level AC-input power shelf with bays for three AC-input power supplies (see Figure 1a). This power shelf can be removed and replaced with the optional two-level AC-input power shelf (see Figure 1b), which provides bays for four AC-input power supplies. Both power subsystems use the same Cisco 12016 GSR AC-input power supply.
In the full redundant standard power subsystem, the three power supplies participate in an N+1 redundant current-sharing scheme in which current sharing is divided among all three power supplies. If one power supply fails, the GSR continues to operate temporarily on the two remaining power supplies.
In the full redundant optional power subsystem, the four power supplies participate in an N+2 redundant current-sharing scheme in which current sharing is divided among all four power supplies. If two power supply fail, the GSR continues to operate temporarily on the two remaining power supplies.
Despite the differences in size and weight required to accommodate the fourth power supply in the optional AC-input power shelf, both power shelves are nearly identical in the way they are removed and replaced.
The shelf is a modular sheet-metal enclosure that attaches to the top of the Cisco 12016 GSR chassis and is secured to the chassis at both the front and back of the power shelf. A captive jackscrew under the power shelf extends from the front panel of the power shelf to the back panel. The jackscrew is threaded to fit an insert on the chassis power interface panel. If it becomes necessary to remove the power shelf from the chassis, you use the captive jackscrew to unseat the connectors on the back panel of the power shelf from the connectors on the chassis power interface panel, and to reseat the power shelf in the connectors when you reinstall the power shelf.
Two captive screws on each of the power shelf front flanges fasten the power shelf to the rack-mounting flanges on each side of the Cisco 12016 GSR chassis. Guide pins on the power interface panel insert into holes on the back panel of the power shelf to provide support for the back of the power shelf and ensure correct insertion alignment between the connectors on the back panel of the power shelf and the connectors on the chassis power interface panel.
The back panel of the standard AC-input power shelf (see Figure 2) has three AC power cord receptacles, one for each power supply bay. Each AC-input power cord receptacle represents one of the power module bays and is connected by an AC power cord to a dedicated AC power source. Electrical connections between the power shelf and the chassis backplane are made through two connectors located on the back panel of the power shelf (not shown).
The back panel of the optional AC-input power shelf (see Figure 3) has four AC power cord receptacles, one for each power supply bay. Each AC-input power cord receptacle represents one of the power module bays and is connected by an AC power cord to a dedicated AC power source. Electrical connections between the power shelf and the chassis backplane are made through two connectors located on the back panel of the power shelf (not shown).
Modular 14-ft (4.3-m) AC-input power cords (three for the standard AC-input power shelf; four for the optional AC-input power shelf) connect the power shelf to the site AC power sources. Figure 4 shows the different styles of AC-input power cords that are available for North America and various international locales. Table 1 lists the power cord options and Cisco product numbers. A spring clip secures the power cord appliance coupler in the receptacle on the back panel of the power shelf.

The following guidelines will help ensure your safety and protect the equipment. This list is not inclusive of all potentially hazardous situations, so be alert.
In addition, observe the following guidelines when working with any equipment that is disconnected from a power source but still connected to telephone or network wiring:
Many router components can be damaged by static electricity. Some components can be damaged by voltages as low as 30V, while static voltages as high as 35,000V can be generated just by handling plastic or foam packing material, or by sliding assemblies across plastic and carpets. Not exercising the proper electrostatic discharge (ESD) precautions can result in intermittent or complete component failures. To minimize the potential for ESD damage, observe the following guidelines:
 | Caution You should periodically check the resistance value of the ESD-preventive strap. The measurement should be between 1 and 10 megohms. |
You need the following tools and parts to remove the standard AC-input power shelf and install the optional AC-input power shelf:
This section contains the following procedures:
Make sure the system is powered down before replacing the AC-input power shelf:
Step 1 Make sure that network administrator is aware that the Cisco 12016 GSR will be removed from operation for a short while.
Step 2 If there are any circuit breakers that control the AC power outlets to which the GSR's AC power cords are attached, turn them off.
Step 3 Disconnect the three AC power cords from the AC-input receptacles on the back panel of the power shelf. Use Figure 6 as a reference and follow these steps:
(a) Disconnect the AC power cords from their source AC outlets.
(b) Pull back the retention clip holding the AC power cord coupler in the AC power cord receptacle on the back panel of the power shelf.
(c) Pull the AC power cord coupler from the AC power cord receptacle on the back panel of the power shelf.
Figure 7 shows the steps in removing an AC-input power supply from the power shelf.
To remove an AC-input power supply, use Figure 7 as a reference and follow these steps:
Step 1 Grasp the outside edges of the front cover over the upper blower module bay and power shelf and pull it straight out to detach the four ball studs on the front cover from the ball stud sockets on the front of the upper blower module bay and power shelf.
Step 2 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. (See Figure 5.)
Step 3 To turn off the power supply and eject it from the power 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 7a.)
(b) Pivot the ejector lever away from the power supply faceplate to eject the power supply from the power shelf backplane connector. (See Figure 7b.)
Step 4 Grasp the power supply handle and pull the power supply halfway out of the bay. (See Figure 7c.)
| Caution The AC-input power supply weighs 12.7 lb (5.7 kg). Because of the weight of the power supply and the elevated position of the power shelf, you should use two hands when handling the power supply. |
Step 5 Use your free hand to support the power supply while you slide the power supply completely out of the bay. (See Figure 7c.)
Step 6 Set the power supply safely aside.
Repeat Step 3 through Step 6 for the remaining power supplies.
To remove the standard AC-input power shelf from the chassis, 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. (See Figure 5.)
Step 2 Loosen the captive screws (two on each side) that fasten the two power shelf front flanges to the rack-mounting flanges on the chassis. (See Figure 8.)
Step 3 Use the flat-blade screwdriver to turn the ejector jackscrew on the front panel of the power shelf (see Figure 8) counterclockwise to unseat the power shelf connectors from the connectors on the chassis power interface panel.
Step 4 Grasp the front flanges on the power shelf and pull the power shelf half way out of the rack. (See Figure 9.)
| Caution An empty AC-input power shelf weighs 20.9 lb (9.5 kg). Because of the rack-mounted height of the chassis, you should be especially careful while lifting and removing the power shelf. To prevent injury, keep your back straight and lift with your legs, not your back. Avoid sudden twists or lateral moves. |
Step 5 Grasping the power shelf flanges with both hands (see Figure 9), slowly lift the power shelf off the chassis and pull it out of the rack.
Step 6 Set the power shelf safely aside.
If you plan to return the standard power shelf to the factory, repackage it in the shipping container you received with the replacement optional power shelf.
To install the optional AC-input power shelf, 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. (See Figure 5.)
| Caution An empty optional AC-input power shelf weighs 41.8 lb (19.0 kg). Because of the rack-mounted height of the chassis, you should be especially careful while lifting and installing the power shelf. To prevent injury, keep your back straight and lift with your legs, not your back. Avoid sudden twists or lateral moves. |
Step 2 Grasp the power shelf front flanges with both hands, lift the power shelf to the top of the chassis, and set the bottom edges of the power shelf sides into the tracks on the sides of the chassis top. (See Figure 10.)
Step 3 Slide the power shelf onto the top of the chassis until the connectors on the power shelf back panel are within approximately three inches (7.6 cm) of the connectors on the chassis power interface panel.
Step 4 Seat the power shelf in the chassis power interface panel connectors. Use Figure 11 as a reference and follow the steps outlined below:
(a) Verify that the two guide pins on the chassis power interface panel are correctly aligned with the two holes on the back of the power shelf and that the ejector jackscrew aligns with the insert on the chassis power interface panel.
(b) Carefully push the power shelf until the two connectors on the back of the power shelf contact the two connectors on the chassis power interface panel.
(c) Use the flat-blade screwdriver to turn the ejector jackscrew clockwise to seat the power shelf connectors in the connectors on the chassis power interface panel.
When you cannot turn the ejector jackscrew any farther, the connectors are completely seated and the power shelf front flanges should be against the rack-mounting flanges on the chassis.
Step 5 Insert and tighten the captive screws (two on each side) on each power shelf front flange to secure the power shelf to the rack-mounting flanges on the chassis.
Figure 12 shows the steps in installing an AC-input power supply in the standard power shelf, but the steps are exactly the same for the optional power shelf. The only difference is that you install two power supplies in the two upper bays of the optional power shelf and two power supplies in the two lower bays.
| Caution The AC-input power supply weighs 12.7 lb (5.7 kg). Because of the weight of the power supply and the elevated position of the power shelf, you should use two hands when handling the power supply. |
To reinstall an AC-input power supply, 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. (See Figure 5.)
Step 2 Lift the ejector lever spring clip on the replacement power supply and pivot the ejector lever until it is perpendicular to the power supply faceplate. (See Figure 12a).
| Caution To prevent damaging 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 just makes contact with the connector on the backplane of the power shelf. (See Figure 12b.)
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 12c.)
Repeat Step 2 through Step_4 for the remaining power supplies.
Figure 13 shows how to reconnect AC power cords to the AC input receptacles on the back of the optional AC-input power shelf after it has been installed on top of the Cisco 12016 GSR chassis.
To reconnect source AC to the optional power shelf, use Figure 13 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. (See Figure 5.)
Step 2 Beginning with the far right AC receptacle on the back of the power shelf (when facing the back of the power shelf), pull back the retention clip and plug the AC power cord coupler for that receptacle into the AC receptacle. (See Figure 13.)
Step 3 Release the retention clip over the power cord coupler to secure the power cord coupler in the AC receptacle. (See Figure 13.)
Step 4 Repeat Step 2 and Step 3 for the remaining AC power cords.
Step 5 Verify that the source AC circuit breakers servicing the source AC receptacles for the power shelf are switched on.
To check system operation after replacing the AC-input power shelf, follow these steps:
Step 1 Verify each of the following:
Step 2 Verify that the green LED labeled PWR OK on the power supply faceplate is on. This indicates that the source AC voltage is within the nominal operating range of 200 VAC to 240 VAC.
If the LED labeled PWR OK is off, verify the following:
Step 3 Verify that the three amber LEDs labeled FAULT, TEMP, and ILIM are off.
If the LED labeled FAULT remains on, replace the existing power supply with a spare power supply. If the LED labeled PWR OK on the spare power supply goes on, return the faulty power supply for replacement.
If the LED labeled FAULT on the spare power supply remains on, suspect a faulty power shelf backplane connector in that power shelf bay.
If the power supply fails to operate properly after several attempts to power it up, contact a Cisco service representative for assistance.
Because of the increased height of the optional power shelf, the upgrade kit includes a replacement snap-on front cover for the upper blower module bay and optional power shelf.
To install the replacement front cover, follow these steps:
Step 1 Hold the front cover by its outside edges and align the four ball studs on the back of the cover with the sockets on the front of the chassis.
Step 2 Push the front cover until all four ball studs snap into their sockets and the front cover is flush against the front of the chassis.
