HP 840Z 96-A thunderbolt card was found in the system but the cable is not connected

[abbottwhite]

HP 840Z 96-A thunderbolt card was found in the system but the cable is not connected, the thunderbolt cable has come out of the socket and I do not know where to plug it back into on the motherboard. I am using a HP840z work station Dual core. and HP THUNDERBOLT-2 PCIE 1-PORT 1/0 CARD

look at the attached image for the internal connections for the TBolt 2/3 cards on the HP zx20/x40 lines of workstations

you may also need the optional external "Video Passthrough Cable" cable that connects from the tbolt card to the video card

For the Z840, here is the installation manual: HP Thunderbolt 2 PCIe Card installation (Z840/640/440/230)

Hi, thanks fr getting back to me , but i am unable to locate that connector e72, I found e73 which has the correct configuration and another two connectors (see attached) , is it any of these ? Can you point me to a pdf or diagram which  has all the connectors marked clearly in it. the pdf sent is rather vague. Thankset of pins please see pics for details.

the cables used to connect the TBolt card to the motherboard varies depending on the workstation model "z" x20/x40 series

you MUST install the TBolt card in slot number #5 or it will not work

HP THUNDERBOLT 2 SIGNAL CABLE Only part# (751366-001) for the z440/z840

FOR HP Z840 / ZX40 WORKSTATIONS
- 15 INCH cable, 5 PIN TO E73 on motherboard 7 PIN END To HEADER on TBolt card

Z840: E72 TBT1 (Thunderbolt Card Header), E73 [no label, 5 pin Thunderbolt Header]

Note:
in an HP Z840 with two CPUs and BIOS 1.0, turn the computer off, and then
move the E3 jumper from the default 2-3 position to the override 1-2 position.

Thank you all for the help. i was able to find the pin connectors  thanks to the manual you provided. for the Z840. it was quite  hard to find them as the pins were covered by another cable, very hard to get at too not a lot of room to get your fingers in there. 

The reason the cable came out was because i had to turn off the fans to do a manual Bios update as this Workstation not connected to the internet. I guess i must have dislodged the  cable when disabling the fans.

For others looking for the location of the HP TB-2 and -3 card's GPIO cable attachment on the Z440/Z640/Z840 motherboards below is a picture I found in my stash from the HP Japan official document related to this. By the way, yes there is a solved forum post on using the HP TB-3 card in the ZX40 workstations.

Hi SDH,

you mentioned there is a solved forum post reagrding the HP TB3 card in Zx40 workstations.

Would you mind posting a look to that solution? I can get the TB2 card to work, but not the TB3 card.

Cheers

I'm unable to find the post I thought I had about that, and now worry that it was false information I provided.

Our friend DGroves here is the person I consider a HP Thunderbolt 2 and 3 expert given that he has worked with those PCIe cards for years now both personally and as a high level enterprise IT specialist. He would know... 

HERE is a post I found related to the old info I had... it indicates that HP had been working on the TB3-in-ZX40 project but later moved on to officially use that TB3 card in their ZX G4 workstation family:

yes, the HP TBolt 3 card does/will work in a z840 and was a official HP supported configuration

the HP TBolt3 card itself is a reference intel "Alpine Ridge" based card 

i suspect the issue is driver related, the TBolt 3 card uses newer and slightly different drivers than the TBolt 2 card

also you absolutely must uninstall the existing drivers before install the TBolt 3 card and then run the  sp74948 pkg

also don't forget to install the card in the supported slot (#5)

official TBolt2/3 card driver pkg  sp74948.exe

the intel "Nuc" uses a compatible TBolt 2/3 driver that is a later driver revision
