What the System Console Does
The system console displays status and error messages generated by firmware-based
tests during system startup. After those tests 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 Sun Netra T5440 Server Service Manual
for your server.
Once the operating system is booted, the system console displays UNIX system
messages and accepts UNIX commands.

Initially, you might have to configure that hardware, and load and configure
appropriate software as well.
You must also ensure that the system console is directed to the appropriate port on
the server's back panel. Generally, the one to which your hardware console device is
attached (see
). You do this by setting the input-device and
