Power supply pin configuration

We have pulled the stock power supply out of our ML370 servers and replaced them with the reduntant (3 power supply) version. This has left us with numberous stock power supplies that we would like to use on a project that we are working on.

We have done extensive research into the ATX12V power supply specifications but find that your power supplies do not conform to that specification exactly. We could really use your assistance in identifying the pin-configuration of these power supplies.

1. The pin coloring on the standard 10 pin ATX connection does not mirror that of the normal configuration, could you please confirm that the actual connections are the same or send us a spec sheet on what the pin configuration is.

2. There is a 14 pin connector on the power supply (only 9 are used) that we have no data on.

The primary problem we are having is that we cannot get the power supply to turn on. This is done by grounding the Pwr_on wire on the 10 pin ATX connection with normal ATX power supplies, but it doesn't do the trick with yours. We figure it must have something to do with the 14 pin connector.

All we need off of this power supply is a good 12V, 5v & 3.3v power source.

Thank you for your time.
