Fru Eeprom; Smbus Interface; Voltage Regulators; Cpld Interface - Nvidia ConnectX-6 User Manual

FRU EEPROM

FRU EEPROM allows the baseboard to identify different types of Mezzanine cards. FRU EEPROM is accessible through SMCLK and SMDATA. FRU EEPROM
address is defined according to SLOT_ID0 and SLOT_ID1 and its capacity is 4Kb.

SMBus Interface

ConnectX®-6 Lx technology maintains support for manageability through a BMC. ConnectX®-6 Lx 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.

Voltage Regulators

The voltage regulator power is derived from the OCP 3.0 edge connector 12V and 3.3V supply pins. These voltage supply pins feed onboard regulators that
provide the necessary power to the various components on the card.
CPLD Interface
The adapter card incorporates a CPLD device that controls the networking port LEDs, as well as an implementation of the OCP 3.0 host scan chain. It draws
its power supply from 3.3V_EDGE.
