SMBus Interface
ConnectX-6 Dx technology maintains support for manageability through a BMC. ConnectX-6 Dx PCIe
stand-up adapter can be connected to a BMC using MCTP over SMBus or MCTP over PCIe protocols as
if it is a standard Mellanox PCIe stand-up adapter. For configuring the adapter for the specific
manageability solution in use by the server, please contact Mellanox Support.

Voltage Regulators

The voltage regulator power is derived from the PCI Express edge connector 12V supply pins. These
voltage supply pins feed on-board regulators that provide the necessary power to the various
components on the card.

Heatsink

The heatsink is attached to the ConnectX-6 Dx IC in order to dissipate the heat. It is attached either by
using four spring-loaded push pins that insert into four mounting holes, or by screws. ConnectX-6 Dx
IC has a thermal shutdown safety mechanism that automatically shuts down the ConnectX-6 Dx card in
cases of high-temperature event, improper thermal coupling or heatsink removal.
