You can get all of the documentation
here
Also, Judging that the LEDs are not corresponding with the servers actual status (processor LED), This server may have been taken apart and the wires to the status leds were incorrectly reconnected. I would look at the documentation for the motherboard and compare to the wiring diagram. The RAM May be an issue. Depends on whether the machine makes it past POST (Power On Self Test). If it does, The ram is fine. If not, I would inspect that beep code further. It probably has something to do with the memory. If the memory is malfunctioning, you will get no response from the machine other than beep codes and status leds. According to the
documentation, the closest match for your beep code means this:
207-Memory Configuration Warning -
DIMM In Socket X does not have Primary Width of 4 and only supports standard ECC.
Advanced ECC does not function when mixing DIMMs with Primary Widths of x4 and x8.
Audible Beeps: 1 long, 1 short, or none
Possible Cause: Installed DIMMs have a primary width of x8.
Action: Install DIMMs that have a primary width of x4 if Advanced ECC memory support is required.
