Once the system is in a state where the individual power supply bay information is not being reported, the condition can be cleared by gracefully powering the chassis down, waiting AT LEAST 15-20 seconds, and then powering the chassis back up. Please refer to article# 000004789 (How to stop and power down gracefully an X-Series chassis) for steps to gracefully shut down the chassis prior to powering it down.
It will still be possible for the chassis to enter into the failed condition in the future if a very short duration power "hit" or power "glitch" is observed. It is very important to note, however, that although the chassis is still susceptible to this reporting error, there is no loss of actual power supply capacity. This is a cosmetic reporting error only.
