Troubleshooting the PEM

Check the following to help isolate a problem with the power subsystem:

• Is the Power LED on each AC PEM on (green)?

–

If yes, the PEM is connected to an active 240 VAC AC power source and is supplying power to

the chassis.

–

If the Power LED is not on, and if no other LEDs are on, verify that the AC power source is

providing valid power. If necessary, try connecting the AC PEM to another wall outlet or power

supply.

• Is the Fault LED on (yellow)?

–

If yes, it indicates that the PEM is connected to an active 240 VAC power source but is not

providing power to the chassis. Check that the AC PEM is properly inserted into the chassis and

that its power switch is on.

• Check the status of the AC PEM using the show environment command.

Note The show environment command provides accurate information on the AC PEM only

when using Cisco IOS Release 12.2(4)XF1, 12.2(4)BC1a, or a later release. If using an

earlier release, the show environment command will not correctly identify the AC

PEM’s error messages.

• If none of the above suggestions correct the problem, the AC PEM could be faulty. Contact a service

representative for further instructions.
