Troubleshooting a PCM

A green LED is lit on the power supply when it is operational. When a PCM fails, a yellow LED is lit on the power supply.

You will see a message similar to the following example on your system console when a PCM fails:

WARNING: Core Power Supply 2 Failing
WARNING: Redundant power lost
