MCX542B-ACAN/MCX542B-ACUN Specifications
NVIDIA 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.
Please note that in standby mode, only port0 is available.
