3750X Unbalanced power supply message

[cpied]

Had a problem this morning with one switch in the stack had no lights on front panel, check power supply it had green lights, then unplugged switch to no avail. Then got idea to disconnect stacking cables and switch came back and is still working properly. Review the log which showed this message: Mar 24 08:27:53.485: %PLATFORM_STACKPOWER-4-UNBALANCED_PS: Switch 2's power stack has unbalanced power supplies. Do you know what could cause this. Thanks.

This error message UNBALANCED_PS indicates that there is a switch in the power stack (indicated by number in the message) with no supplies while at the same time there is a switch in the power stack with TWO supplies.

If this message only appeared once, you can safely ignore this (this can be seen while you are configuring priorities at the switches).

If it is occuring multiple times, i would like to see following outputs:

1. Show Version

2. Show stack-power

3. Show env all

Can you also have a look at the below bug:
