Socket Direct (2x PCIe x16) Cards Installation Instructions

NVIDIA ConnectX-6 InfiniBand Ethernet Adapter Cards User Manual

The hardware installation section uses the terminology of white and black harnesses to differentiate between the two supplied cables. Due to supply chain variations, some cards may be supplied with two black harnesses instead. To clarify the difference between these two harnesses, one black harness was marked with a “WHITE” label and the other with a “BLACK” label.

The Cabline harness marked with "WHITE" label should be connected to the connector on the ConnectX-6 and PCIe card engraved with “White Cable” while the one marked with "BLACK" label should be connected to the connector on the ConnectX-6 and PCIe card engraved with “Black Cable”.

Warning

The harnesses' minimal bending radius is 10[mm].

Warning

Applies to MCX654105A-HCAT, MCX654106A-HCAT and MCX654106A-ECAT.

Warning

The installation instructions include steps that involve a retention clip to be used while connecting the Cabline harnesses to the cards. Please note that this is an optional accessory.

Warning

Please make sure to install the ConnectX-6 cards in a PCIe slot that is capable of supplying the required power and airflow as stated in Specifications.

Step 1: Slide the black and white Cabline CA-II Plus harnesses through the retention clip while making sure the clip opening is facing the plugs.

Safety Precautions

The adapter is installed in a system that operates with voltages that can be lethal. Before uninstalling the adapter card, please observe the following precautions to avoid injury and prevent damage to system components.

  1. Remove any metallic objects from your hands and wrists.

  2. It is strongly recommended to use an ESD strap or other antistatic devices.

  3. Turn off the system and disconnect the power cord from the server.

Card Removal

Note

Please note that the following images are for illustration purposes only.

  1. Verify that the system is powered off and unplugged.

  2. Wait 30 seconds.

  3. To remove the card, disengage the retention mechanisms on the bracket (clips or screws).
