Chapter 8 Replacing Cisco ASR 1000 Series Routers Field-Replaceable Units
Removing and Replacing a Cisco ASR 1006 Router Power Supply
Removing the AC Power Supply from Cisco ASR 1006 Router
Because of the power supply redundancy, there is no need to power off the Cisco ASR 1006 Router
before removing one of the AC power supplies.
The Cisco ASR 1006 Router has two of the same type power supplies in power supply slot 0 and power
supply slot 1.
To remove a Cisco ASR 1006 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 Before you turn off a power supply, make certain the chassis is grounded.
Step 3 Turn the power supply Standby switch to the Standby position.

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.
