Hi, today I got these log:

So, Is there some problem ?

Problem Description:


%C6KPWR-SP-4-PSOUTPUTDROP: Power supply [dec] output has dropped
A drop in output power was detected in the specified power supply. The input power may be offline or has changed from 220V to 110V.

Recommended Action: Reseat the input power cable and verify that the input line voltage is adequate. Enter the show power command to display the power status.

In order to investigate the real problem and root cause, we need to check the input line outage issue first.
But show power command line outputs shows PSU 1 still fine at this time.

Action plan:
1. check the if there is any power outage.
2. if power system reports input power still ok at that time period, It indicated PSU operational fail. I need to be RMA.

Hi, Thank you so much.

It is power issue. We make a RMA.

I've seen this alarm before.  A lot of times.

Each PSU has two power input.  If one of the power input source is flakey or loose, you'll get errors like this.  Alternatively, if one of the power input connectors in the PSU is faulty, same thing.
