I have an ASRock ROMED8-2T/BCM motherboard. I bought it new. It has been working correctly for a year and a half with 4 x 32Gb 2933Mhz ECC RDIMMs and an epyc 7282 and a corsair AX 1600i as PSU. Then when I turned on this morning it didn't work as expected. I have no POST, no debug codes, no bmc heartbeat leds, I plugged both the motherboard LAN1 and BMC to the router as usual. Neither is detected, the ethernet port is blinking orange on one side for the LAN1. But it is blinking from both sides on the BMC port. Still not detected by the router,, not trying to receive a DHCP lease. The weirdest thing is when I try to turn it off by holding the power button it doesn't turn off. Even a minute later. I cleared the CMOS battery, now I can reach the BMC. But I cannot update BIOS (gives me verify bios error). I downloaded 3.80 from the asrock website. Nor can I turn on the server, it appears as "Powered Off" in KVM of the BMC. Clicking on "Power On Server" does nothing. And I still have no way of turning it off by holding the power button, only by turning off the PSU. ------------- ASRock fatal1ty B350 itx/ac AMD Ryzen 1300X I211 Gigabit Ethernet |

Try disconnect the system from power, press and hold the power button, pull out the CMOS battery and clear CMOS. Leave the system like this for about 10mins then replace the CMOS battery and try to power back on. It sounds like you could have some corrupted firmware values from an improper shut down or possibly a dying CMOS battery. Next I would try a new CMOS battery to rule that out. If you have one available to test with you should also try a different PSU, if it has a bad rail it could be causing all your issues. If none of that helps then you can open a support ticket with ASRockRack: https://event.asrockrack.com/tsd.asp" rel="nofollow - https://event.asrockrack.com/tsd.asp -------------

Thanks for your reply. I followed the same steps to actually get the BMC to work. It didn't work before. I didn't even get the BMC heartbeat LED. Then once inside the BMC I didn't see anything in logs. I tried the PSU self test which was green. I don't know what else to try. I'll change the CMOS battery and let you know. ------------- ASRock fatal1ty B350 itx/ac AMD Ryzen 1300X I211 Gigabit Ethernet |

Good luck  Just a bit of a caution, the PSU's self test is very rudimentary, I highly doubt it checks for out of spec ripple for example. AFAIK it only checks voltage with a light artificial load applied. Odds are, its probably fine but I wouldn't rule it out based on a self diagnostic, those tend to be more of a gimmick than a useful troubleshooting tool. -------------

Thanks for your insight? Any other stuff I can do to rule something else out? Changing CMOS battery did nothing. And I didn't know dead CMOS batteries caused issues like this. I thought the system would still boot or at least try to. ------------- ASRock fatal1ty B350 itx/ac AMD Ryzen 1300X I211 Gigabit Ethernet |

Dead CMOS battery + momentary power loss can cause corrupted data in the firmware. Typically it makes no difference aside from losing time and date and BIOS settings when you lose power to the system. I am afraid I am out of my area of experience with ASRock's workstation/server boards. I have never used them so I can't think of much else to try. It may be worth trying the system with everything non essential disconnected. Reseat RAM, CPU etc and power up with just the monitor connected, no keyboard, mouse or USB devices. I have seen systems experience all kinds of issues caused by a faulty USB device. Bit of a long shot but worth a try. -------------
