Hi, recently our hosting provider scheduled a power maintence to replace one of their UPSs. Our DL580 G5 has 4 redundant power supplies. Two were plugged into the A circuit and two were in the B circuit.
When the B side was shut down, the server went down too. I expected the server to stay up. What caused it to go down? If we lost a single power supply, I would expect the server to stay up. Can someone explain it to the newbie?
Thanks,
Mike
