About Setting Up a Console

To install your server or to diagnose problems, you need some way to enter system
commands and to view system output. There are four ways to do this.
1. Attach an alphanumeric (ACSII) character terminal to serial port A.
You can attach a simple terminal to serial port A. For instructions, see
Initiate a Reconfiguration Boot" on page
2. Establish a tip connection from another Sun system.
For information about establishing a tip connection, refer to the OpenBoot 4.x
Command Reference Manual, which is available at http://docs.sun.com, under
Solaris on Sun Hardware. Refer to the Sun Fire V890 Server Product Notes for late-
breaking details.
3. Install a local graphics console on your server.
The server is often 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 card in a PCI slot, and attach a monitor, mouse, and
keyboard to the appropriate rear panel ports. For detailed instructions, see
Configure a Local Graphics Console" on page
Note – Power-on self-test (POST) messages are output to serial port A (ttya) or the
RSC console only.

Icon Description
This setting forces the power-on self-test (POST) and
OpenBoot Diagnostics to run during system startup. The
Power button functions the same as when the keyswitch is in
the Normal position.
This setting forces the system to power off immediately and
enter 5-volt standby mode. It also disables the system Power
button. You may want to use this setting when AC power is
interrupted and you do not want the system to restart
automatically when power is restored. With the keyswitch in
any other position, if the system was running prior to losing
power, it restarts automatically once power is restored.
The Forced Off setting also prevents an RSC console from
restarting the system. However, the service controller card
continues to operate using the system's 5-volt standby power.
