The heatsink is attached to the ConnectX-6 IC to dissipate the heat from the ConnectX-6 IC. It is attached either by using four spring-loaded push pins that

insert into four mounting holes or by screws.

ConnectX-6 IC has a thermal shutdown safety mechanism that automatically shuts down the ConnectX-6 card in cases of high-temperature events,

improper thermal coupling or heatsink removal.

For the required airflow (LFM) per OPN, please refer to Specifications.

For MCX653105A-HDAL and MCX653106A-HDAL cards, the heatsink is compatible with a cold plate for liquid-cooled Intel® Server System D50TNP platforms

only.

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 protocol as if it is a standard NVIDIA PCIe stand-up adapter. For configuring the adapter for the specific manageability solution in use by the server,

please contact NVIDIA Support.
