Mini USB Type B Connector
The BlueField-2 BF2500 DPU Controller uses a Mini USB 2.0 Type B device. The purpose of the USB connector is debugging and loading new versions of the
operating systems and firmware.
External PCIe Power Supply Interfaces
The BlueField-2 BF2500 DPU Controller consumes power from two power sources; an external+12V through an 6-pin ATX connector (reference #9) and an
additional+12V through the PCIe x16 edge connector. The BF2500 DPU Controller’s special circuitry balances the power consumption between these two
power sources. Each power source must be capable of supplying up to 75W of power. The 3.3V AUX from the card’s PCIe edge connector is used for logics
on the BF2500 DPU Controller. This logic includes power for buffering logic for signals to the card’s edge connector, power for the FRU EEPROM, and
