Hi folks, I am having the exact same issue as described in another post that is currently closed. (Unfortunately I can’t post a link to that post. so i have quoted it below.

Hi,
I Just have received my new Supermicro H12SSL-i MB to build my home server. Unfortunately seems that my system is broken as I am not able to start the machine.
After I turn on the power supply the LE1 LED blinks quickly until the LEDM1 (BMC) starts to blinks quickly and then if off. The BMC then goes in the heart beat mode that I find normal from manual, however the LE1 should stay lit.
I have access to BMC through IPMI interface, but the CPU and the RAM amount is not correct as I am using Epyc 7262 and 4x Samsung 3200 stick’s. I need to mention that I have re-seated the CPU several times.

Anyone ahs any idea what might be wrong?
Thank you for your support.

@gvi70000 I was wondering if you ever resolved this? I replaced my motherboard and the 2nd one is doing the exact same thing. I called SuperMicro about the 1st board and they said it was a faulty motherboard which is why I went for a replacement. Any idea what could be causing the board to not power on at all? I am able to access the BMC but both board report an incorrect CPU and RAM regardless of what I have installed and the powering on via the header pins or the BMC does nothing.

Thanks!

BMC is basically a separate computer, so it can be accessible with broken MB.

Other than disconnect everything but 1xCPU and 1x ram stick - I have no idea.
Probably faulty MB/CPU/PSU.

Never had a SuperMicro server, but had similar problem with dell - had to replace MB.
