G5 Front Panel Pinout

I have been working on making a pinout for the front panel connection board that comes in the PowerMac G5 cases.

 

I have NOT verified this by actually hooking anything up. I have only pinned it out with a multi-meter and used the standards for USB, Firewire and Audio to assign the actually pins to something meaningful.

 

I am unsure of the LED and Power Switch because something just does not seem right with what I have found out. I am thinking it might be safer to wire up the LED and Switch seperate from J1. Firewire power is at 30V and that seems like a lot for a LED.

 

Again, use this at your own risk. I take no responsibility for any damage that might incur.

 

EDIT: I have converted this to a PDF and changed my numbering to match what Neo used. Also included in the PDF drawings for USB and FireWire connectors.

For the LED front panel pins just look at this...

Could you make a pic for better understanding?

 

Thanks :P

Neo,

 

I changed my pin number to match yours, added some figures and made it into a PDF. I have left everything blank right now for the LED and Power button assingments because there is some conflict with what I have found and what you have.

 

You have J1-18 as the ground for the power button which is the same connection for the power pin of the Firewire connector. This can't be right.

 

I dont have the power button here with me here at work so I cant do anymore research on this until tonight when I get home.

Is this "Front Panel Board Cable" the one you guys are using? http://www.apple.com/support/powermac/doit.../caseparts.html

 

That cable will not plug into a PC motherboard. What we are talking about is how to connect the front panel pcb to a PC motherboard. You have to cut off one end then wire it up with standard PC connectors so it can hook into a PC mobo.

Hi All!

 

I'm going to give it another shot... my first attempt made my mobo stop booting with the usb connection... I believe it must be related to the cable type I was using... To make it easier to try I'm also using Asus' Quick Connector thing.

 

I'll get back to you... later! Hopefully
