Table 18. 68-pin SCSI connector pin-number assignments

Serial ports

The server has two standard serial ports: Serial port A and
Serial port B. The operating system can use and share both
serial ports; however, the integrated Netfinity Advanced Sys-
tem Management processor can use and share only Serial
port A.
Some application programs require specific ports, and some
modems function properly only at certain communication
port addresses. You might need to use the Configura-
tion/Setup Utility program to change communication port
address assignments to prevent or resolve address con-
flicts.
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 Configura-
tion/Setup appears, press F1.
3. From the main menu, select Devices and I/O Ports;
then, press Enter.
Note: The Devices and I/O Ports choice appears only
on the full configuration menu. If you set two lev-
els of passwords, you must enter the administra-
tor password to access the full configuration
menu.
4. Select the serial port; then, use the arrow keys to
advance through the settings available.
5. Select Save Settings; then, select Exit Setup to exit
from the Configuration/Setup Utility main menu.

Serial-port connectors

The following table shows the pin-number assignments for
the 9-pin, male D-shell serial-port connectors on the rear of
the server. These pin-number assignments conform to the
industry standard.
