HP Z440 / Z640 Front panel pinpout

HP Recommended
Z440

Hello.

I would like to use my Z440 Mainboard inside a custom case and need the pinout of the front-panel socket.

Does anybody have a schematic of the front panel -header (component 25 in the manual) or did anybody figure out at least which ones are for power on?

Hello @DGroves. 

 

Thank you for your answer. I did a fair amount of a research and found a couple of schematics for the xw Model line and one for z420, too. Unfortunately, I did not see any indication that the pinout on a z440 is identical. The fact that the speaker is connected to a dedicated pin on the motherboard, made me think the pinout on the z440 must have changed compared to the z420 and previous models.

You likely only own a motherboard for the Z440.  Why don't you look at eBay for Z440 bare bones?  Ideally you'd get one with the Windows sticker on the back.  That way you know the motherboard is "branded" to run the HP Windows 10 installer media.  You can download that from HP if yours is a Windows branded motherboard but you need a valid serial number to do that download.  Hence, the value of actually having the case that the motherboard came in... so you know what you are dealing with.  Linux branded motherboard can't do that trick.

 

The front interface unit that screws onto the case can be bought too, as can the 3 cables, but with shipping and individual costs bare bones is the way to go.  Try to get one that has its motherboard still in.  The top USB port in that front interface is a high amperage one that must have some different wiring than all the prior Z workstations.  I think it is the same in the Z440 and the Z640.  It gets blown too easily... I've bought one that way but in it all else works fine.  My guess is that HP has fixed that on new replacements bought directly from them.

 

You won't find pinouts for these I'm quite sure.
