I am working on a Dell Poweredge T320 w/ dual 750W stock PSUs. I shut the server down for routine cleaning and when I plugged it back in, both PSUs started clicking and nothing turned on, not even the indicator LEDs on the PSUs. The server is usually on a Dell UPS but I also tried plugging into the wall and nothing changed. I have seen another thread (about the same server) where the PSU was clicking and they determined it was a PSU failure, but that one only had one PSU, and I find it strange that mine would have both fail at the same time. Does anyone know what could have caused this issue?
