Hardware Requirements
A system with a PCI Express x16 slot (two FCI B2B x8 connectors) is required for installing the card.
ConnectX-5 cards for OCP are complaint with automatic hosts-count detection per OCP Mezzanine
www.opencompute.org/wiki/Server/SpecsAndDesigns
).
Airflow Requirements
ConnectX-5 adapter cards are offered with two airflow patterns: from the heatsink to the network
ports, and vice versa, as shown below.
Please refer to the "Specifications" chapter for airflow numbers for each specific card model.
Software Requirements
See Operating Systems/Distributions section under the Introduction section.
Software Stacks - Mellanox OpenFabric software package MLNX_OFED for Linux, WinOF-2 for
Windows, and VMware. See the Driver Installation section.
Unpacking the Product
Unpack the adapter package and place them on an antistatic surface.
Check the parts for visible damage that may have occurred during shipping.
For proper operation and performance, please make sure to use a PCIe slot with a
corresponding bus width and that can supply sufficient power to your card. Refer to the
Specifications section of the manual for more power
Mellanox recommends populating MCX542B-ACAN in a standard PCIe x8 OCP connector
which exposes PCIe lanes in a straight manner. In case the OCP slot exposes PCIe lanes in a
reversed manner, MCX542B-ACAN supports automatic lane reversal with FW image from April
2019 release and above.
All cards in the system should be planned with the same airflow direction.

The adapter is being installed in a system that operates with voltages that can be lethal.
Before opening the case of the system, observe the following precautions to avoid injury and
prevent damage to system components.
Remove any metallic objects from your hands and wrists.
Make sure to use only insulated tools.
Verify that the system is powered off and is unplugged.
It is strongly recommended to use an ESD strap or other antistatic devices.
