Root Cause
This issue is due to either a faulty or disconnected power cable, or a power supply failure.
Solution
Check the output of the show env power detail command and research the power supply status. In this
example output, both chords are connected but the second shows only 1200W capacity instead of 3000W and
it needs to be for the 220V AC on the N7K−AC−6.0KW. The power source tested OK. Replace the power
supply.
