AC-Input Power Shelf Overview

There are two AC-input power shelves available for the Cisco 12016 GSR:

Both power subsystems use the same Cisco 12016 GSR AC-input power supply.


Figure 1: Standard and Optional AC-Input Power Subsystems (Front Covers Removed)


Note Under normal operating conditions, the power shelf and its power modules are partially hidden by the chassis front cover shared between the upper blower module and the power shelf.

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.

Either the standard or optional power 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).


Figure 2: Back Panel of the Standard AC-Input Power Shelf


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).


Figure 3: Back Panel of the Optional AC-Input Power Shelf


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.

Safety with Equipment

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.

Safety with Electricity

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:

Preventing Electrostatic Discharge Damage

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.

Checking System Operation after Replacing the Power Shelf

To check system operation after replacing either the standard or optional AC-input power shelf, follow these steps:

Step 1 Verify each of the following:

Each power cord should be connected to a dedicated AC power source, if possible. Each AC-input power supply operating in the nominal range of 200 VAC to 240 VAC and requires a minimum service of 20A, North America or 13A, international.

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.
