Thanks,
Will look into it. But without the pinout scheme would be difficult to fire up the board…
All I am trying to do is to play with PCI to PCIexpress adapters with VGA.
DELL don't seem to publish the pinout anywhere themselves, but it's not difficult to make an educated guess based on online searches...
...the actual front panel only serves 4 functions - power on, reset, power LED and activity / storage LED, all of which are built into a small PCB and cable attached to the server case

The cable from this plugs into a header on the motherboard near the memory slots, with the red cable edge nearest the processor sockets

The circuit traces on the front panel PCB give clues about where the likeliest pinouts for each function are but as there are so few likely combinations, it wouldn't take long to safely test & confirm for each.
Also, if you haven't already noticed, another thing to mention about this board is that the installation of a second processor requires the addition a voltage regulator module (VRM) in the dedicated slot. There seems to be two different part numbers for this, depending on whether you're using a redundant power supply or not - 0M495 for redundant PSUs or else 7G041 for any others (obviously worth double-checking).
