UART Interface Connectivity
A UART debug interface is available on the DPU cards via the NC-SI connector. The below table describes the UART interface location and connectivity per
the NC-SI connector type on the DPU you have purchased.
NC-SI Connector Type UART Interface Location and Connectivity
30-pin For DPUs with onboard BMC, the UART interface is that of the BlueField-2 device. For DPUs without onboard BMC, the UART
interface is that of the NIC BMC device.
