i need help with front panel connectors on a dell xps 9100..motherboard 5dn3x

dell xps 9100 case sucks..has bad airflow.. i just got me a nzxt phantom 820 full tower for 115$ i could not past that up.. so im just taking the i7 930 and the motherboard (5dn3x ) and the ram out of the dell to put in the nzxt case with a corsair 600watt and a gigabyte 7950

but how can i hook the power' hdd led etc all up to this dell motherboard?

since all the wirers are in one connector box in the dell xps. and it dont say the lay out on the MB

so im not sure what the pinout is on the motherboard

so how can i find out how to use the nzxt front panel connectors on this motherboard?

Did a manula for the motherboard not gone with the system? If not then the trick would be to find them. Those LED pins are usually marked on the actual circuit board - if abbreviated.

This is the problem with OEM systems like this. Their motherboard is proprietary, so unless you can find someone on a forum that has the pinout, don't mind poking at it with a multimeter, or just trial and error... you're out of luck.

I ran into similar problem with OEM proprietary stuff back in the mid 2000's with Dell's PCs, I'm surprised they still do this kind of nonsense.

Try the Tested forums, you might have more luck.

no manula no markings... what are tested forums?

wire box....left to right top = 2 black wirers red orange

bottom just 2 browns.under the 2 blacks...... as shown in that link

. i have done so much googling on this.. could never find anything

tested.com, but it is pretty dead over there.

some ppl say.. just take the power wire from the nzxt case and put it on the mb pins till i find the one that will work

what would be the harm in that if any??

I did some searching online and found this: http://www.roberthancock.com/dell/fpconn.html. I can't guarantee the accuracy of it in regards to your system.

It looks like Dell uses Foxconn motherboards, when I look at the manuals for one of their more recent boards, I see this diagram:

A smart thing to do would be to get the original front panel PCB from your Dell case, and trace out each of the lines with a multimeter. This would ensure you have everything correct the first time.

Just remember that LEDs are polarity sensitive, so if you hook them up backwards, they will not light up. The switches do not care which way they are connected.

huuum. nicee.. but on my board my pin lay outs are side ways not up and down. so would that still be the same?

also some one postyed this to me

For this type of front panel there's the following pinout:

2468

****

*****

13579

Pins 2 & 4 = Power LED (green)

Pins 6 & 8 = Power switch (orange)

Pins 1 & 3 = HDD LED (red)

Pins 5 & 7 = Reset switch (blue)

For switches polarity is unimportant, for LEDs colored wire is + and solid white or black wire is ground. If wires aren't not color-coded (I think they are all black in NZXT for coolness factor), the little triangle means +, or if that fails, it's usually with the writing downwards (towards the 5 pin row, edge of the board), and anyway the worst that can happen is that LEDs will not light up, so you just reverse them.

ok i have it all set up. pin lay out worked fine

but i had to rig the usb up to get it to boot up right.

it kept saying front usb not detected and it would not load windows

so i had to take out the usb drive out of the dell case and lay/stick it in the dvd tray and use that usb cable and usb drive for it to boot up right.

any way around this? so i can just use the usb from the nzxt case. i have a few of them working but when i unplug F-usb 4 or 5

and hook the nzxt usbs up to it i get usb not detected.. but i can hook up the wire from dell and it works fine..
