If your server is configured without a local graphics console, you need to attach an alphanumeric (ASCII) terminal (or establish a tip connection) to the server in order to install the system software and to run diagnostic tests. For background information, see "2.10 About Communicating With the Server".
Alternatively, you can install a local graphics console on the server; see "2.12 How to Configure a Local Graphics Console".
For information about establishing a tip connection, see your Sun Enterprise 220R Server Owner's Guide or the OpenBoot 3.x Command Reference Manual, an online version of which is included with the Solaris System Administrator AnswerBook that ships with Solaris software.
Connect the terminal's data cable to serial port A on the server's back panel.
Connect the terminal's power cable to an AC outlet.
Set the terminal to receive:
At 9600 baud
An 8-bit signal with no parity and 1 stop bit
See the documentation accompanying your terminal for more information.
You can now issue system commands from the terminal keyboard and view system messages. Continue with your service or diagnostic procedure as needed.
