Has anyone else experienced the board randomly deciding it doesn’t want to turn on? Or am I the only lucky one?
BIOS = 2.06
BMC = 2.07
What I did so far…
The power button was not responsive; I did the typical stuff and pulled the power for the PSU, assuming it was locked up, but I also noticed that none of the fans were spinning. I waited a while and plugged it back in, and it still will not power up, nor will the BMC respond (it seems flakey anyway on a typical day, or when you reboot the host, it sometimes resets). So I removed it from the rack and put it on my workbench, assuming something must have failed. I removed all the PCIe cards (Two highpoint x4 NVMEs (Bottom two slots as they are 16x), a dual 25Gb SFP28 (Top slot), and two Samsung 990 Pro NVMEs installed on the motherboard. I even disconnected all the fans. Swapped PSU, thinking it could be the PSU that decided to quit. Same thing, nothing happens, but I do see the LEDs and looked at the manual PDF on Asrock’s site, and it seems that it is waiting for a power event; I then tried to connect a benchtop ATX Front Panel switch in the off chance that I grabbed the only screwdriver that couldn’t create a circuit for the ATX power switch. Still nothing. Checked and inspected all of the power cables, ensuring the pins were seated correctly. I then went a tested the PSUs and all power was well within it’s operating range, both PSUs checked out fine. I looked to ensure that the 24-pin to 4-pin ATX signal cable included with the box was seated correctly and that a pin didn’t get pushed out or was somehow damaged from sitting in the 4U case and not moving. I started removing the memory and testing the DIMMs in different configurations. I also tested them in a SuperMicro board with an Xeon; nothing was wrong with any DIMM. According to the manual, I installed just one, two, and four in the slots indicated. Nothing, just some green LEDs.
What has worked…
So, I decided to disable the BMC using the jumper pin, and as soon as I did, it fired up. So it seems that the BMC just decided to perform self-immolation; I’m very disappointed with this right now. I figured I’d reach out to Asrock Support. This will be the second time I’ve contacted them since I got this board, and they never responded to the first one. That first issue involves the OpenBMC randomly disconnecting when rebooting the host. Since support is non-existent, I wanted to see if anyone here has experienced anything similar. Given that I run it headless, having out-of-band management is essential for me, and with that possibly not working anymore and no GPUs (A380, A750, T400, 3090 non-Ti, 6950XT) that I’ve tried will display POST, I don’t even want to use it as a workstation.
Does anyone know how to flash the BMC without the BMC being enabled? I never thought I’d have to ask something like this, but I can’t find any information, and ASRock Rack doesn’t reply to support requests. I did look at Newegg to see if I can return It, but since I’m past that window, I’m stuck trying to get this working properly again.
