Replace a Power Supply in the Cisco ASR 1002 Router

This section provides instructions for removing and replacing the AC power supply and the DC power supply in a Cisco

ASR 1002 Router. Before you begin, make certain the chassis is grounded. Two power supplies must be installed in the chassis

at all times to ensure sufficient cooling. The system fans are inside the power supply units and must spin for cooling. Because

all the system fans can be powered by one power supply, the second power supply unit does not have to be powered on, but it

must be installed.

If a power supply is removed, the system can run with only one power supply for a maximum of five minutes. The router waits

five minutes before shutting down. This five-minute window allows time to replace a failed power supply.

Note Two power supplies must be installed in the chassis at all times to ensure sufficient cooling. The system fans are inside

the power supply units and must spin for cooling. Because all the system fans can be powered by one power supply, the

second power supply unit does not have to be powered on, but it must be installed.

Caution If you remove a power supply, the system can run for a maximum of five minutes before the system shuts down.

The fans and power elements are independent within the power supply. Therefore, it is not required that the

replacement power supply be energized within five minutes. The only requirement is that the power supply be

installed in the chassis, which energizes the fans and maintains proper system cooling.

To remove a Cisco ASR 1002 Router AC power supply that is not operating normally (and then replace the AC power supply

within five minutes), follow this procedure:

Step 1 Slip on the ESD-preventative wrist strap that was included in the accessory kit.

Step 2 Turn the switch to the off (O) position and unplug the AC power cord.

Step 3 Unscrew all of the power supply captive screws.

Step 4 Grasping the power supply handles, pull the power supply from the chassis.

Step 5 Replace the AC power supply within five minutes or the system will shutdown

You have removed an AC power supply from the Cisco ASR 1002 Router and now must replace the AC power supply within

five minutes.

Step 1 Insert an AC power supply in power supply Slot 0 or power supply Slot 1 until it is full seated.

Step 2 Tighten the captive installation screws.

Step 3 At the rear of the router, check that the power switch is in the Off (O) position.

Step 4 Insert the AC power cord into the power inlet and then turn it On (I).

Step 5 To ensure that the AC power cord does not interfere with other cables or wires, dress the AC power cable in one of the

following ways.

a. Leave a small service loop in the AC power cord from the inlet and then secure the power cord through the AC power

supply handle as shown in Figure 14. Or go to 5b.
