I have an old server with S1200BTL with E3-1220 and 2x2 GB ram.
The server worked fine for a while, after that was discontinued. Now i'm trying to use it again, but it doesn't boot.
It powers on just fine, coolers start, but then i can hear 5 beeps, and nothing happens.
The diagnostics LEDs are lit in an OOOO OXXO pattern, which does not exist in the manual.
I've tried resetting the CMOS, but still the same.
As i said earlier, the server was fine when pulled offline few months ago.
Any idea if i could do something before RMA?
I checked the set of lights and it is indicating an undefined error. This means that the unit is not reaching far enough to understand what's wrong with it.
I would suggest following our http://www.intel.com/support/motherboards/server/sb/CS-029657.htm troubleshooting guide for Boot Issues.
