I have a PowerEdge 1800 server that was given to our office by a customer after the system failed and would not power on. I diagnosed the issue as a failed power supply. However the customer who was unwilling to pay $500+ for one from a 3rd party vendor went with using a PC with raid to satisfy there needs thus giving our company the server.
The business here would LOVE to get the server functioning and using it for an excellent file server or small webhosting server so we purchased a 3rd party Antec TP-650 power supply that matches the same wattage and connectors that the originial psu had. But when I plugged the psu in (all PCI cards removed, 2 cpu's installed, all drives disconnected) the front light began flashing repeatedly blue as well as the rear system information light also blinked blue. I noticed a green LED on the motherboard was flashing in sequence with the blue lights as well.
When having the rear CPU / CASE fan plugged in I noticed that I could hear slight 'pulses' in the rotation of the fan while the front case fan, simply did not move. This type of hearing the rear CPU/CASE fan pulse with a slight spin up, spin down very repeatedly made me wonder if the power supply I bought new was failing. When connecting my voltmeter into a 4 pin Molex connector I was reading 4.5v & 9.2v when I should have been getting 5.0v and 12.0v respectively. After that I tried the antec PSU on a Vostro PC and it worked beautifuly giving the full 5.0 and 12.0 outputs.
I have swapped surge strips, power cables, and tried different outlets to no avail. Can someone tell me if it's possible for a PE 1800 to support a 3rd party PSU? Is it possible certain pins inside the 24+4 pin PSU cable are different on the Antec than on the originial OEM psu?? Or should I assume the motherboard is toast at this point??
I greatly appreciate ANY assistance here.
Thanks!!
