This server was working fine when we took it out the rack, now it seems lifeless.
I have tried all the normal checks, booted off one cpu, changed memory.
When you put power to the board, it turns on it self. It will not turn off with the switch. The CPU fan will be on full speed and it does 3 long beeps. However on the 3rd beep it cuts short.
On the sys_sts LEDS, it is orange
I'm not sure what else to try.

According to the manual for that model of motherboard, three beeps indicate a memory error. So, you've probably had a DIMM go bad or work itself loose. Track down the bad DIMM(s) by seeing which ones prevent the system from booting and replace it/them.
