This section contains specifications and port pinout information for the base I/O ports of your system and system head node, as follows:
The system auto-selects the Ethernet port speed and type (duplex vs. half-duplex) when the server is booted, based on what it is connected to. Figure A-1 shows the Ethernet port.
Table A-5 shows the cable pinout assignments for the Ethernet port operating in 10/100-Base-T mode and also operating in 1000Base-T mode.

Each system head node has a 9-pin serial interface connector. These ports are capable of transferring data at rates as high as 230 kbps. Other features of the ports include the following:
Programmable data, parity, and stop bits
Programmable baud rate and modem control
Figure A-3 shows an example serial port.
