extending power switch from pc?

<< < (2/2)

ghettodish:
The top pin in each column (above picture) is what you want to use. I wrapped a wire around the base of each of those pins, then taped them in place. I then reinstalled the ribbon cable and routed the wires through a hole I drilled under the floppy drive.

Optiplex GX 260

I think that this is your complete pinout:



From the pin-side:

PIN ---- DESCRIPTION --> CONNECTS TO FNT_PNL Pin #

1 Removed and blocked on the connector

2 PWR SWITCH LEFT SIDE (Both) --> 20

3 GND --> GND

4 HDD LED NEG --> 22

5 PWR LED GREEN POS --> 23

6 HDD LED POS --> 5 thru R19

7 GND --> GND

8 ESUP SWITCH RIGHT SIDE (Both) --> 28

9 PWR LED YELLOW POS --> 27

10 N/C

11 GND --> GND

12 N/C

13 ESUP LED NEG --> 24

14 ESUP LED POS --> 5 Thru R20

15 GND --> GND

16 GND --> GND


I've rewired some Dells (270N) previously for some projects.  I did some documentation of the pinouts etc. as I was hacking the front panels a lot.  For more information one what it all means, try clicking the picture or the link below.

Cheers, Zebidee ;D

Good info, but that pinout seems to be mirrored. Your picture is for the I/O card inside the computer(behind front USB ports), not the one on the front panel under the power button.

It is good to know what all the other pins are for!

Yeah, that's right.  It is exactly what you need, the same cable & wires, just that the pinout is laid out for the pin header on the "I/O card" rather than the power-switch card.  You can simply mirror it to work out what the pins do from the power-switch card's perspective.

I worked this out as I wanted to redirect the USB and audio to USB & audio ports I built into the front door of the cabinet.  Turned out to be a real pain, but I got there in the end.

BTW, you can use the LED pins to wire-up your own cabinet LEDs! This adds a professional touch.  Have an LED on whenever mains power is present, another indicating hard disk activity, etc.
