Following these steps to remove an AC power supply from the Cisco ASR 1004 Router.
Step 1 Slip on the
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 four power supply captive screws and grasp the handles on both sides of the 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.
