a.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.
For more detailed information seeSpecifications.
