A customer called me about this computer and I am trying to troubleshoot this beast. I get the solid green light on the mobo in the top right, and the the BMC LED 1 is blinking, BMC LED 2 is very faint but solid.

The most that I can get is the power LED turning on for about .2 seconds, and the fan just barely starting to spin. I have tried the following but nothing changes

Pulled "right" CPU and memory (I think this is CPU 2?)

Pulled PCIe GPU

Tried 2nd PSU

Pulled CMOS and Cleared CMOS

Switching PSU modes

I thought that I had plugged in a LAN cable to the BMC power (IPMI?) but just found that it is power 5 and not 3 on the diagram. I will try that next.

ANYTHING ELSE? I'm not figuring this out at all.
