Also I'm hearing 4 short beep after POST - Recovery failed.
And system status LED is blinking amber.
Could you please give me the Serial Number and PBA number of the server board?
I regret to inform you that based on the details provided seems to be a corrupted BMC issue. Unfortunately, the markings you sent me are showing the board out of warranty. The best suggestion here if the BMC update and forced update are not working, will be to replace the server board.
Is there any other question or help needed?
