Hi all,
My shiny new home server has suddenly packed up. I've narrowed it down to the Supermicro X11SSM-F MB (because I've managed to boot another machine using the Seasonic S1211-430 PSU). What test can I run to diagnose further?
The symptoms:
I noticed that I couldn't log on via SSH. So I went to the box and saw that the power-button LED on the case would blink for a second and the case fan would spin for a second, then everything stops. And after a short pause, the same thing happens.
When I took the side of the case off, I could see that the green power LED on the MB turns on for a couple seconds, and the CPU fan spins for a second. Then everything stops. After a 2 second pause, the same thing happens. The BMC led on the MB stays on all the time.
I can log in to the MB via IPMI, but the console unsurprisingly doesn't connect.
I've now disconnected everything from the MB bar the main power supply connector and the CPU power supply connector. The CPU and the CPU fan are both still plugged in. But RAM, drives, USB cables, cards, and now even the connections for the case front panel are removed.
My understanding is that motherboard should beep in order to complain that there's no RAM. But instead there is no change to the behaviour described above.
The only other PSUs and MBs I've got are in a :
* Dell Dimension 3000,
* Dell Dimension 9200
* Dell XPS 8500
None of PSUs have the second 8-pin CPU power cable so I don't think I can test the Supermicro board using those PSUs. I have, however, managed to boot the Dell XPS using the Seasonic PSU (albeit using the 4-pin CPU power connector, rather than the 8-pin CPU connector that I use for the Supermicro MB).
I've written to the Supermicro vendor. But is there anything I can do in the meantime to narrow down the problem?
(edit 1: to clarify LED status)
(edit 2: corrected to reflect that I've booted another system using the PSU)
