SMBus Interface
ConnectX-6 technology maintains support for manageability through a BMC. ConnectX-6 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.
