I recently purchased a ProLiant DL580 at auction and would like to put it in use as a file server. All drives, memory, processors, SCSI boards...seem to be attached appropriately. When I try to power up and run the "SmartStart" nothing happens. It has one power source that shows 2 green lights, but I get nothing. There is a light flashing right next to the power button, it flashes amber (over the light bulb). What should I try first?
