the server Receives power, IMM responds, and it can be accessed but won’t turn on. The I/O board, midplane have been swapped, and now we’re waiting for the chassis, but I don’t think that will solve the problem. I believe it’s more related to firmware or configuration, but I can’t figure it out. Recently, the system was updated, worked for 3 days, then shut down and never powered on again. If anyone has knowledge and can guide me on what it might be, I’d appreciate it.”
