Remove and Replace a Power Supply
This section provides instructions for removing and replacing the AC power supply and the DC power supply in a Cisco
ASR 1004 Router. Before you begin, make certain the chassis is grounded.
Remove and Then Replace an AC Power Supply
To remove a live Cisco ASR 1004 Router AC power supply that is not operating normally (and then replace the AC power supply
within five minutes), follow this procedure:
Slip on the ESD-preventative wrist strap that was included in the accessory kit.
Step 1
Before you turn off a power supply, make certain the chassis is grounded.

Step 3
Step 4
Unplug the power cable from the AC inlet on the back of the power supply and the power source.
Step 5
Unscrew the power supply captive screws.
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.
Grasping the power supply handles, pull the power supply from the chassis.
Step 6
Replace the AC power supply within five minutes or the system will shutdown.
Step 7

Step 2
