Nvidia BlueField-2 InfiniBand User Manual

NVIDIA BlueField-2 InfiniBand/Ethernet DPU User Guide 42
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 to External PCIe Power Supply
Connector Pins.
RTC Battery
The DPU incorporates a COIN TYPE LITHIUM BATTERY CR621 for RTC (Real Time Clock).
eMMC Interface
The DPU incorporates an eMMC interface on the card's print side. The eMMC is an x8
NAND flash and is used for Arm boot, operating system storage and disk space. Memory
size is either 64GB or 128GB, where 128GB is effectively 40GB with high durability.
MMCX RA PPS IN/OUT Interface
through the x16 PCIe interface. The power cable should be supplied
by the customer.
Warning
Applies to the following OPNs: MBF2H516C-EECOT, MBF2H516C-
EESOT, MBF2M516C-EECOT, MBF2M516C-EESOT.
