Microserver Gen8 failed to power on

[shooter556]

I bought a 2nd hand server. There is no storage disk in it originally. I managed to attach an SSD to it using SATA slot.

iLo is 2.80 and BIOS is J06 (2014 or 2015 version I didn't remember it clearly, not the latest one)

I deployed esxi 7.0.3 today, and the server is running well for several hours.

Then I use ESXi to upgrade the iLo from 2.80 to 2.82 successfully. 2.82 iLo can be accessed I'm quite sure about this.

But about 15-20min later, the server suddenly shutdown without any sign. The LED turned to amber.

I try to press the power button, it flashes with green LED for about 10 seconds, then turn to amber again, 5 seconds later, blinking LED again for 10 secends, turn to amber ..... repeatedly.

And iLo cannot be accessed any more.

I tear apart the machine, unplug the SSD, unplug the raid card, remain only 1 DIMM slot (and changed another slot afterwards). Then try to power it again, but no luck, same issue.

Suspecting PSU issue, I try to use another good ATX PSU, still no luck, same issue.

I tried to replace another CPU --- originally it's E3-1220Lv2, I changed it into E3-1265Lv2 (I plan to replace it after doing some test), no luck, same issue.

I also attached monitor to the server, didn't show anything on the screen.

I heard that PSU's fan is spinnning, while green LED is blinking, but the sys fan didn't spin at all.

I also noticed that on the board, when power LED is blinking green, there is a green LED lights on, but shuts after 10 seconds.

Any idea about that?

Because of the 2nd hand, I'm ready the mainborad is fried (or some other parts) somehow.

Hello there, have you tried clearing the NVRAM from the system board?

This is how to do it for Gen8 microserver:

Best regards.

Ok, I tried swith 6 to on, power it, same issue.

Then I unplug the ac cord, trun 6 to off, plug the cord, same issue.

Also tried s1 s5 s6 to on, to use redundent ROM, same issue.

No luck, I think this machine may have some other HW issues, just didn't output any video, and restart repeatedly.
