On your server, the system console comes preconfigured to allow input and output
only by means of the system controller. The system controller must be accessed
either through the serial management port (SER MGT) or the network management
port (NET MGT). By default, the network management port is configured to retrieve
network configuration using DHCP and to allow connections using SSH. You can
modify the network management port configuration after connecting to ALOM CMT
through either the serial or network management ports. For more information, see
"Activating the Network Management Port" on page

Alternative System Console Configuration

In the default configuration, system controller alerts and system console output
appear interspersed in the same window. After initial system installation, you can
redirect the system console to take its input from and send its output to a graphics
card's port.
For the following reasons, the best practice is to leave the console port in its default
configuration:
In a default configuration, the serial management and network management ports
■
enable you to open up to eight additional windows through which you can view,
but not affect, system console activity. You cannot open these connections if the
system console is redirected to a graphics card's port.
In a default configuration, the serial management and network management ports
■
enable you to switch between viewing system console and system controller
output on the same device by typing a simple escape sequence or command. The
escape sequence and command do not work if the system console is redirected to
a graphics card's port.
The system controller keeps a log of console messages, but some messages are not
■
logged if the system console is redirected to a graphic card's port. The omitted
information could be important if you need to contact customer service with a
problem.
You change the system console configuration by setting OpenBoot configuration
variables. See
