Nvidia BlueField-2 InfiniBand User Manual

NVIDIA BlueField-2 InfiniBand/Ethernet DPU User Guide 40
Having a trusted onboard BMC that is fully isolated from the host server ensures the
highest security for the DPU boards.
For more information, please refer to Connecting to BMC Interfaces.
1GbE OOB Management Interface
The DPU incorporates a 1GbE RJ-45 out-of-band port that allows the network operator to
establish trust boundaries in accessing the management function to apply it to network
resources. It can also be used to ensure management connectivity (including the ability to
determine the status of any network component) independent of the status of other in-
band network components.
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.

10Mb/s and 100Mb/s modes are not supported on this interface.
Warning
For DPUs with integrated BMC: 1GbE OOB Management can be
performed via the BlueField-2 device or the integrated BMC.
