    3D Printed PCIe full height bracket

    I bought half height cards by mistake, and needed some full height pcie brackets. So I made these up in solidworks, and 3D printed them. Hope this helps somebody out there.

    Works on the Mellanox ConnectX-3, which also has product numbers HP 544QSFP 649281-B21. It might work on other cards, or if you send me the dimensions I can tweak it for other cards as well.

    Flashing firmware on HP 544QSFP 649281-B21

    Also for those having trouble with the HP 544QSFP 649281-B21 not detecting any connection while the link lights are on, try updating the firmware. There are a lot of broken links, but I did not need to flash the generic firmware - the latest HP firmware worked great for me.

    I found the guides super confusing... but it was actually easy when I figured out the process. Regardless of whether you want the generic firmware or not, you can still update the HP firmware first and try it out...

    Download the latest HP firmware bin file here:
    Drivers & Software - HPE Support Center.

    Download and install the firmware flashing software here for windows (bottom of page):
    http://www.mellanox.com/page/management_tools

    and then run from an elevated cmd prompt:
    flint -d /dev/mst/mt4099_pci_cr0 -i <path to bin file> burn

    Very nice...

    I'm trying to track down full height brackets for MCX311A-XCAT Mellanox Connectx-3 single port SFP+ NIC and was wondering if this would work for my application (if the 2nd port hole was filled in) - or are there other differences as well (such as light port size and position) and (Infiniband vs SFP port positioning and dimensions)?

    Unfortunately I don't own any other cards. However, the easy way to find out would be to compare images of the half-height cards - if the single-port card port is in the same position as one of the ports on the double-port, half-height cards, or if the single port cards have a blank space on the PCB where the second port would go, then I would imagine it would be very likely that this bracket would fit. Otherwise, if you let me know some kind of dimensional reference, I can make a STL file for your card too.
