Note Using a tie wrap for the AC power cable is optional and not necessary. However, if you do attach the AC power cable

to a power supply tab and then you remove the AC power cable for some reason, check for any damage to the cable

after you cut the tie wrap off. If the power cord is damaged, replace it immediately.

Note Turn the power supply switch to On (I) after both sides of the power cord are connected.

Step 6 Plug the AC power supply cable into the AC power source.

Step 7 Place the AC power supply switch to the On (I) position.

Step 8 The power supply LEDs light when power is supplied to the router.

This completes the procedure for connecting an AC power supply in the Cisco ASR 1002 Router. You have completed a live

change-out procedure (that is, removing and replacing an AC power supply) for an AC power supply not operating properly in

the Cisco ASR 1002 Router within five minutes.

Removing the DC Power Supply

Before you can remove a DC power supply from the Cisco ASR 1002 Router, you must remove power from the power supply.

Caution Make certain that the chassis ground is connected before you begin removing and installing the power supply.

To remove the DC power supply from the Cisco ASR 1002 Router, follow this procedure:

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

Step 2 Place the power supply switch in the Standby position.

Step 3 Turn off the branch circuit breaker before touching terminal screws. Then start loosening terminal block screws to

remove wires.

Step 4 Remove the ground leads from the terminal block in this order.

a. Negative ground lead

b. Positive ground lead

c. Ground lead

Step 5 Unscrew all of the power supply captive installation 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.

Step 6 Grasping the power supply handles, pull the power supply from the chassis.
