  1. Install the ConnectX-6 Dx OCP 3.0 card in a PCIe slot that is capable of supplying the power levels mentioned below for the appropriate use case.
  2. ConnectX-6 Dx adapters supplement the auto-negotiation specification to get better bit error rates and longer cable reaches. This supplemental feature only initiates when connected to another NVIDIA Ethernet product. 

  3. In Standby mode only port0 is available.

Power numbers are provided for passive cables only. For board power numbers while using active cables, please add the outcome of the following formula to the passive cables' power numbers stated below. 

Power while using Active Cables = Card Power with Passive Cable + Active Module Power x Number_of_Modules / 0.9 (efficiency factor).
