System Console Openboot Configuration Variable Settings - Fujitsu SPARC Enterprise T2000 Administration Manual

System Console OpenBoot
Configuration Variable Settings
The SPARC Enterprise T2000 system console is directed to the serial management
and network management ports (SER MGT and NET MGT) by default. However,
you can redirect the system console to a local graphics monitor, keyboard, and
mouse. You can also redirect the system console back to the serial management and
network management ports.
Certain OpenBoot configuration variables control from where system console input
is taken and to where its output is directed. The table below shows how to set these
variables in order to use the serial management and network management ports, or
a local graphics monitor as the system console connection.

* POST output will still be directed to the serial management port, as POST has no mechanism to direct its output
to a graphics monitor.
The serial management port does not function as a standard serial connection. (If
you want to connect a conventional serial device (such as a printer) to the system,
you must connect it to ttya not the serial management port.)
It is important to note that the sc> prompt and POST messages are only available
through the serial management port and network management port. Note that the
ALOM CMT console command is ineffective when the system console is redirected
to a local graphics monitor.
In addition to the OpenBoot configuration variables described in
other variables that affect and determine system behavior. These variables are
discussed in more detail in
