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 and the scan
chain. It draws its power supply from 3.3V_EDGE.
Heatsink
A heatsink is attached to the ConnectX®-6 Dx IC to dissipate the heat. It is connected by four spring-
loaded push pins that insert into four mounting holes.
ConnectX®-6 Dx IC has a thermal shutdown safety mechanism that automatically shuts down the
ConnectX®-6 Dx card in case of a high-temperature event, improper thermal coupling, or heatsink
removal.
