PowerEdge 1800 - No Power

Hello,

I have a client who has a PowerEdge 1800 server with redundant power supplies (part# DPS-650BB A).  These are 675W units.  

The server experienced a power outage/surge late yesterday evening.  Both of the server's power supplies were plugged into an APC UPS with the Dell supplied "Y" power cord.  However, upon trying to power the server back on this morning the client was not able to do so.  I see no power LEDs, fans don't spin up, etc.  I have tried different power cords, different power outlets, etc. to no avail.

So a couple of questions:

1. Is there some Dell process to try and get the server to power up? (e.g. I found an old post by someone on another website that said to hold the power button on for 1 minute, press again, etc.).  I tried various things to get it to turn on, but so far it has shown no life.
2. Could the power surge have knocked out both power supplies even while both were connected to the APC UPS?  It seems unlikely to me (albeit possible I suppose).
3. Could it be the power distribution board and not the power supplies?
4. Would it be possible to remove the redundant power supplies and the power distribution board and replace them with just one standard Dell server power supply?  This would be a lot cheaper even though they are losing redundancy.

Any recommendations or help on how best to identify the issue without first ordering $1000 worth of new power supplies and a power distribution board would be most appreciated.  Server was purchased in 2006 so is well out of warranty.

Thank you!
