Nvidia BlueField-2 InfiniBand User Manual

NVIDIA BlueField-2 InfiniBand/Ethernet DPU User Guide 54
1. Make sure the system is powered off.
2. Determine the correct orientation of the UART connector on the card before
inserting the cable. Pay attention to the UART cable key as it should guide you to the
corresponding mating connector orientation on the board interface.
3. Carefully connect the 30 pin connector on the board to the mating cable.
4. Connect the USB cable to the desired interface master, which can be a motherboard
or any desired server. Do not leave the USB side unattended.
Uninstalling the DPU
The USB 2.0 Type-A to 30pin Flat Socket cable is intended for internal
system use and is sensitive to excessive pulling force and crushing
forces. Therefore, proper care must be taken during the installation
procedure. The best practice is to install the cable properly the first
time around carefully .
Important
Once a cable is plugged into the UART interface, its other side must
be plugged into a USB connector. Leaving the USB side unconnected
might lead to unexpected behavior of the DPU card.
