External Pcie Power Supply Connector - Nvidia BlueField-2 InfiniBand/VPI DPU User Manual


For DPUs with integrated BMC: 1GbE OOB Management can be performed via the
BlueField-2 device or the integrated BMC.
1GbE OOB Management LEDs Interface
There are 2 OOB management LEDs, one green and one amber/yellow. The following table describes
LED behavior for DPUs with or with onboard BMC.

External PCIe Power Supply Connector


Applies to FHHL P-Series DPUs only, OPNs MBF2H516A-CEEOT and MBF2H516A-CENOT.

FHHL P-Series DPUs require supplementary power from a 6-pin ATX power supply connector
in addition to a minimum of 75W power through the x16 PCIe interface. The power cable
should be supplied by the customer.
The FHHL DPUs incorporate an external 12V power connection through a 6-pin ATX connector. The
DPU includes a special circuitry that provides current balancing between the two power supplies;
the 12V from the PCIe x16 standard slot and the 12V from the ATX 6-pin connector. Since the power
provided by the PCIe golden fingers is limited to 75W, a total maximum of up to 150W is enabled
through both the ATX 6-pin connector and the PCIe x16 golden fingers. The actual power
consumption is in accordance to the mode of operation of the DPU and is split evenly between the
two power sources.
For the external PCIe power supply pins, please refer
RTC Battery
The DPU incorporates a COIN TYPE LITHIUM BATTERY CR621 for RTC (Real Time Clock).
