Serial connectors
Your server has two standard serial connectors: Serial connector A and Serial
connector B.
Some application programs require specific connectors, and some modems function
properly only at certain communication connector addresses. You might need to use
the Configuration/Setup Utility program to change communication connector
address assignments to prevent or resolve address conflicts.
Viewing or changing the serial-connector assignments:
Complete the following
steps to view or change the serial-connector assignments:
1.
Restart the server and watch the monitor screen.
2.
When the message Press F1 for Configuration/Setup appears, press F1.
