Hp z840 Thunderbolt card Internal Connectors

Hello All

Can not find the internal connector cable for Hp Z840 Workstation. part number for "751366-001".

At least I can find a picture of the wiring diagram will be enough.

I'm having problems with the machines Z840 for the Thunderbolt cable has changed. Unfortunately I do not have it in changed cable.

the HP thunderbolt carrd (F3F43AT) uses a specific slot and will not work in any other slot (for my z820 it's slot 5)

 

no other cable is needed to use the hp card  unless you require video passthrough option

(IE-push monitor display through thunderbolt. which requires a thunderbolt compatable monitor)

 

please read the link below and note the section:

 

Use with a range of devices that support the Thunderbolt™ and Thunderbolt™ 2 standards without requiring a cable adapter.3

the optional  DisplayPort to DisplayPort cable is part of the offical HP kit, so i'm guessing you have aquired just the card only from somewhere?

Sorry, I should have been more explicit. I am after the GPIO cable that connects the card to the mainboard. Any suggestions as to where i might be able to get my hands on a replacement?
As per original poster, the part number is 751366-001. Thanks

what you call the "GPIO cable part number " is the optional video passthrough cable and can be found at numerous resellers

the thunderbolt 2 card (falcon ridge) was used by HP, Dell,Supermicro and others. i suspect what you want/need is the internal GPIO cable that connects the cards header to the motherboard thunderbolt I/O pins this cable is diffrent for each vendor

 

 

you might want to contact supermicro, if hp parts is unable to help they might be able to give you a pinout of the cards header pins

Not optional im afraid, not video either. When card is installed without, you are prompted that "Thunderbolt PCIE card is inserted but not plugged in".

Have tried sellers mentioned and more however they no longer stock the part. Supermicro only sell connectors for their own mainboards which is a straight connector.

Was really hoping that HP spares might be able to sell me another but no luck there either...

here's half the battle, this link has the pinout from the ASUS mb to the card,

 

you will need to change/map the asus motherboard pin location to the HP MB pin location

 

go to page 45

Great find! I think your right, might have to fabricate my own cable. That diagram is awesome help though, will just need to find the same connector diagram for my HP Z440 mainboard connector now.

Yeah, i was thinking the same. If it was going to be anywhere, it'd be there.... Unfortunately not, just trawled through the doco and no detailed pin layout
