R710 Boot Failure

Hello everyone,

I've got an R710 that will not boot.

At power up, the fans run full speed for perhaps half a second, then the server goes into standby mode.  Attempting to start the server with the power switch results in nothing at all.  If I pull the power I can repeat this same cycle.  If I leave the server plugged in long enough, it tries to reboot but does not succeed.

Nothing is displayed on the screen at all, and there is zero indication from the server as to the nature of the error except every so often the front display will show a System Software Error, but no details are shown.  This error is only shown very briefly before the server shuts down.

I have removed everything down to CPU1, a single DIMM in slot A1 with the same result.

Connecting via DRAC produces nothing in the system logs.

History:

I've been fighting with a failing PERC 6/i in this server, and I have recently replaced the card, replaced two drives (might not have needed to do this, but the original 6/i showed them as failed), and rebuilt the array.  For a few days after doing this, the server seemed fine, but then it started crashing again (but I could still restart the server)

Not being sure what the issue was, I tried another battery on the 6/i, and tested the BIOS battery for the heck of it.  No change.

Can someone please help shed some light on this?  Am I looking at a failed main board?

Thank you,

Scott
