PCI Express Interface

The table below describes the supported PCIe interface in ConnectX-5 and ConnectX-5 Ex adapter
cards.

ConnectX-5
ConnectX-5 Ex

FRU EEPROM

FRU EEPROM allows the baseboard to identify different types of Mezzanine cards. MEZZ FRU EEPROM
is accessible through MEZZ_SMCLK and MEZZ_SMDATA (Connector A18 and A19). MEZZ FRU EEPROM
address is 0xA2 and its capacity is 4Kb.

Heat Sink Interface

A heatsink is attached to the ConnectX-5 IC in order to dissipate the heat from the ConnectX- 5 IC. It
is attached either by using four spring-loaded push pins that insert into four mounting holes.
ConnectX-5 IC has a thermal shutdown safety mechanism which automatically shuts down the
ConnectX-5 card in cases of high-temperature event, improper thermal coupling or heatsink
removal.

SMBus Interface

ConnectX-6 technology maintains support for manageability through a BMC. ConnectX-6 OCP 3.0
adapter can be connected to a BMC using MCTP over SMBus or MCTP over PCIe protocols as if it is a
standard NVIDIA OCP 3.0 adapter. For configuring the adapter for the specific manageability solution
in use by the server, please contact NVIDIA Support.
Supported PCIe Interface
PCIe Gen 3.0 (1.1 and 2.0 compatible)
through x16 edge connectors
PCIe Gen 3.0/4.0 (1.1 and 2.0 compatible)
through x16 edge connectors
