Question about Compaq ProLiant 3000/5500 Redundant (306558B21) Fan Assembly
I am wondering if you had been doing some work to this when this problem started. Did you take the wires off for the power switch? I have noticed that sometimes if you pull the wires off of the motherboard and put them back on and you put the connector on backwards (assuming that its a 2 wire cable for the front panel) it may not work. Also, if you have a screwdriver handy which Im sure you do, take the plug off of the motherboard and jump the 2 pins that start the system. If it makes the system work then change the switch. If that does not work then try checking the power supplies. Just because the light is no does not mean that the power supply is working correctly. Will the system work with just one power supply hooked up. If so try one at a time. I have also had luck with re-seating the processor and the system then booted correctly. Try reseating the ram. Bad drives, cards and cables can make the system not start. Unplug everything that you can and if it starts, plug one thing in at a time and see if you can eliminate the bad part. Hope this helps...
