XPS 8900 f_panel wiring diagram

Trying to install in a new case and need the f panel wiring diagram to connect the power, reset and hdd light switches to the pin connectors on the motherboard.  Does anybody have a wiring diagram for this.  Called Dell Tech support.  Apparently Dell does not have this or know about how to get one.  I'm kinda of dumbfounded, so I'm turning to anybody on these forums that may have an answer.  Thanks

RE: XPS 8900 f_panel wiring diagram

Dell uses custom connectors between front panels and motherboards. They don't make info about those connectors publicly available, and they differ from model to model.  So unless you can map the wiring yourself or find somebody who already mapped it...

BTW: There's also a top I/O panel and a front USB panel that connect to the motherboard. I don't know if the motherboard will function correctly if those aren't connected if you move to a new case...??

Thanks RoHe.  I eventually mapped this myself through trial and error.  It's just that it would have saved me a bunch of time if Dell would have been more disclosing, but I appreciate your response.

Every company keeps secrets about their hardware...

Glad you got it sorted...

I am undertaking a similar project. Do you have a diagram of the layout that you would be able to provide?

Here's the best I have come up with so far.  I have tested numerous combinations but these are the only ones I can get to work correctly so far. Each connection consists of a red and black wire( at least in my case, assuming black is ground?). The top of the picture matches the top of the board on the XPS 8900 relative to the computer case.

The thread above was for an 8500 and also worked for an 8700 and has a diagram.

The 8900 case looks the same as an 8700 so I would be surprised if they changed it too much.

Thank you for the diagram.

My Dell XPS 8900 front panel connector wires come in different colors from yours. I can connect them in your way and am able to turn up the power. But I encountered " Alert! Power Button Cable Failure" message every time I cold boot. However, after clicking on "Continue", the message disappears, and I am then able to start Windows 10 without other problems.

Does anyone have this Alert message, too? It's annoying!

I'm having the exact same issue! Has anyone figured out how to stop the alert from showing? I do alot of remote work and if I'm not infront of the PC at time of cold reboot, it just hangs at the alert screen.

RE: XPS 8900 f_panel wiring diagram

I had to do a case transplant on my XPS 8900 to support a better graphics card and PSU

I've got the power button and HDD LED connected based on the previous posts diagram, but I am also getting an alert every time I power on the machine.

Does anyone know how to disable the Alert ?

I was thinking about disassembling the power button module and rewiring it for the new case, but that seems a bit excessive.
