I/O connector locations and ports
The following illustration shows the input/output connectors (ports) that are
supported and the expansion slots on the rear of the server.
This section provides information about the input/output (I/O) ports on your server.
These ports include the following:
• Serial port
• Universal Serial Bus (USB) ports
• Console ports
• Ethernet ports
Serial port
Your server has one standard serial port. Some application programs require specific
ports, and some modems function properly only at certain communication port
addresses. You might need to use the Configuration/Setup Utility program to change
communication port address assignments to prevent or resolve address conflicts. This
serial port is also manually configurable from inside the server. The following table
lists the function of each of the connectors that can be used to manually configure the
serial port. You will also need to refer to the figure in “System board options
connectors” on page 35.
