Chapter 1 Configuring the System Console 3
What the System Console Does
The system console displays status and error messages generated by firmware-based
tests during system startup. After those tests have been run, you can enter special
commands that affect the firmware and alter system behavior. For more information
about tests that run during the boot process, refer to the Netra 440 Server Diagnostics
and Troubleshooting Guide.
Once the operating system is booted, the system console displays UNIX system
messages and accepts UNIX commands.
Using the System Console
To use the system console, you need some means of getting data in to and out of the
system, which means attaching some kind of hardware to the system. Initially, you
might have to configure that hardware, and load and configure appropriate software
as well.
A local graphics monitor (frame buffer card, graphics monitor,
mouse, and so forth). See the following:
•“Accessing the System Console Through a Local Graphics
Monitor” on page 29
✓
•“System Console OpenBoot Configuration Variable Settings”
on page 31
✓
*After initial system installation, you can redirect the system console to take its input from and send its output
to the serial port TTYB.
