I/O Port Specifications

This section contains specifications and port pinout information for the base I/O ports of your system and system head node, as follows:

Ethernet Port

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.
