Installing the Power Supply

•OUTPUT FAIL LED is green

Step4 If the LEDs indicate a power problem, see the Chapter5, “Troubleshooting”for troubleshooting

information.

Step5 If you are installing a redundant power supply, repeat these steps for the second power source.

Note If you are installing a redundant AC power supply, ensure that each power supply is connected to a

separate power source in order to prevent power loss in the event of a power failure.

Removing and Replacing the AC Power Supply

This section describes how to remove and replace the AC power supply.

Note The Cisco ASR 903 Router power supplies are hot-swappable. If you have installed redundant power

supply modules, you can replace a single power supply without interrupting power to the router.

Caution To avoid erroneous failure messages, allow at least 2 minutes for the system to reinitialize after a power

supply has been removed or replaced.

Warning

When you install the unit, the ground connection must always be made first and disconnected last.

Statement 1046

Warning

Before performing any of the following procedures, ensure that power is removed from the DC circuit.

Statement 1003

Warning

Only trained and qualified personnel should be allowed to install, replace, or service this equipment.

Statement 1030

Warning

Installation of the equipment must comply with local and national electrical codes.

Statement 1074

Follow these steps to remove and replace the AC power supply:

Step1 Disconnect the power cord from the power source. Do not touch the metal prongs on the power cord

when it is still connected to the power supply.

Step2 Remove the power cord from the power connection on the power supply. Do not touch the metal prongs

embedded in the power supply.

Step3 Loosen the captive installation screws.

Step4 Grasp the AC power supply with one hand, and slide it part of the way out of the chassis. Place your

other hand underneath the power supply, and slide it completely out of the chassis.
