About Communicating With the System
To diagnose problems with your server, you need some way to enter system
commands and view output. There are three ways to do this.
1. If console output is not redirected to the RSC console, attach an ASCII character
terminal to serial port A.
You can attach a simple terminal or modem line to serial port A. For instructions,
see “How to Attach an Alphanumeric Terminal” on page 38.
2. Establish a tip connection from another Sun system.
The tip utility establishes a full-duplex terminal connection to a remote host.
Once the connection is established, a remote session using tip behaves like an
interactive session on a local terminal. For information about establishing a tip
connection, see “How to Set Up a tip Connection” on page 180.
3. Install a local graphics console on your server.
The server is shipped without a mouse, keyboard, monitor, or frame buffer for the
display of graphics. To install a local graphics console on a server, you must
install a graphics frame buffer into a PCI slot, and attach a mouse, monitor, and
keyboard to the appropriate back panel ports. See “How to Configure a Local
Graphics Console” on page 39 for detailed instructions.
