UART
The conga-HPC/EVAL-Server provides four UART ports:
•
two BMC UARTs (X67 and X68)
•
two module UARTs (X65 and X66)
4.4.1
BMC UART
The conga-HPC/EVAL-Server provides two RS232 compliant UARTs on D-SUB9 connectors X67 and X68 from the BMC. Connector X67 supports
full flow control and functions as a BMC UART port while connector X68 functions as a BMC debug console port.
