I just bought a dell t3600 motherboard, and I am making a system to use the cheap xeon 2670. I have assembled it outside of the case, and I am trying to power it on with no success. There is a 28 pin connector with 1 pin removed that is labeled "frontpanel_usb1" and all of the online manuals say something similar. There is nothing printed on the motherboard or any pinout information in the manuals. I have tried shorting out the pins with a screwdriver with no pair working. However, the power supply fan and my cpu cooler fan (plugged into power supply, not motherboard) spin for part of a second when two of the pins are bridged. Clearly the motherboard is sending some sort of signal to the power supply, but it isn't starting the system. I have tested the power supply.
I am wondering if anyone could help me with the pinout of this 28 pin connector, tell me how to determine which two pins are for the power switch by using a multimeter or some other method, or tell me if these are the right pins and something else is wrong with the system.
Thanks.
