Using the System Console
The system console device can be either a standard alphanumeric terminal, terminal
server, Tip connection from another Sun system, or a local graphics monitor. The
default connection is through the serial management port (labeled SERIAL MGT) on
the chassis back panel. You can also connect an alphanumeric terminal to the serial
(DB-9) connector (as TTYB) on the system back panel. A local graphics monitor
requires installation of a PCI graphics card, monitor, USB keyboard, and mouse. You
can also access the system console through a network connection with the network
management port.
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, see Chapter 8 and Chapter 9.
Once the OS is booted, the system console displays UNIX system messages and
accepts UNIX commands.
