Input/output ports
Input/Ou tput por ts Your server has the following input/output (I/O) ports:
• Two serial ports
• One keyboard port
• One auxiliary-device (pointing device) port
• One Ethernet port
• Two Universal Serial Bus (USB) ports
• Two ISM ports
• One system management port

Note: The illustrations in this document might differ slightly from your hardware.
Future releases of the Integrated System Management (ISM) firmware code will
enable the Integrated System Management processor to communicate using a
modem and the dedicated Serial C port.
Serial ports
Your server has two standard serial ports, Serial port A and Serial port B, and a third,
Serial port C, which is dedicated for use by the Integrated System Management
processor. The operating system can use both serial ports (serial port A and serial
port B).
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.
Viewing or changing the serial-port assignments
To view or change the serial-port assignments:
1. Restart the server and watch the monitor screen.
2. When the message Press F1 for Configuration/Setup appears, press F1.
3. From the main menu, select Devices and I/O Ports ; then, press Enter.
Note: The Device and I/O Ports choice appears only on the full configuration
menu. If you set two levels of passwords, you must type the administrator
password to access the full configuration menu.
