OK, Please forgive me if this sounds like a stupid basic question.
I have a Poweredge 2900 with redundant power supplies. This was a standby unit, ready to go. However upon doing a check today, we find that the unit is totally dead. No LED's on the PSU (although we varified power is on both power supplies), no display on the front... nothing ... dead! Can it be that both PSUs are dead? One is off UPS and other is plain old mains supply. One I would expect - but both dead? I am stumped by this.
Does anyone have any idea about this? I dont even get power available LEDs on the PSUs... nothing.
Any sort of idea would be very helpful. Thanks in advance.
