HP z600 Motherboard power on pins

[Chris_4]

Hello,

I have an old HP z600 motherboard that I am using as the basis for a home server.  I accidentally powered it on one time by touching the front panel pins with a knife.  It booted fine but didn't have a keyboard so I shut it down only to realize I did not know which pins were to power it on.  I would like to know what the pinout for the front panel pins are so I can hook up a power button or at least turn it on to do a full systems test.  does anyone know the pins that correlate to the power button? 

Thank You.

Image of the motherboard:

shows a collection of pins at top-right.

Note that "shorting" across any two pins will NOT have any BAD effect, because the pins are for:

* system speaker

* front-panel power LED

* disk-activity front-panel LED

* and so on

All "non-critical" to the health of the motherboard.

So, just keep trying different pairs of pins, until the CPU fan starts to spin.

It was the second set of pins.  If you look at the photo I marked them.  Thank you for your responce I was unsure if I could just test them without causing serious problems.
