IBM x3650 M2 Power Issue

I have an IBM x3650 unit with redundant power supplies. The two units are plugged in. If the left unit is unplugged, the server shuts down meaning power does not fail over to the 2nd unit. On a closer look, I noticed that the DC light on the 2nd unit is off. Does this mean that the unit is faulty.

I looked up the Light Path Diagnostics but did not find any pertinent info.

I believe its faulty.
What happens if you let only the 2nd unit plugged.
Can you start the server ?

I did a UPS battery swap a while back and the server went down when I pulled cable 1.
It's a high profile server and I don't want to request downtime just to test the power unit.
I'm hoping someone may have seen this before and can tell if it's bad.
I ordered a spare power unit just in case but just need to confirm I won't get the same issue after replacement if it has something to do with configuration

You could check IBM Power Configurator / IBM Director

Looks like the AC LED is off as well as the DC one in the photo, if there is no AC going into it then no DC will come out. I'd try plugging it into the mains with a known good power lead.

The AC lights are on, There is AC in the unit
The flash on my phone makes it look like it's off. Without the flash, the picture is very dark.
The power outlets are coming from a UPS unit which powers all the servers.
The 2nd picture is the goo unit with both AC and DC on, but appears off due to flash

I'm not very good with a camera either ;)

Assuming you have swapped the PSUs around to eliminate a faulty one the next thing to go for is the power distribution board. That assumes a single PSU will run the thing rather than it needing both of them combined of course.

Rephrasing the question.
Could a DC LED in an off state indicate missing configuration or bad PSU?
Please skip all troubleshooting steps

Bad PSU to me.
No possibility to check IBM Power Configurator / IBM Director ?
