There are five power rails with the names and source given in the following table. Each QSFP56 uses isolated power, delivered by a dedicated regulator to provide power enable and over-current control per port.

Note: While the card can operate without either AUX power connected, power to the QSFP cages, DDR, and DIMMs requires at least AUX power connector 1 to be connected.
