About The Sc> Prompt - Sun Microsystems Sun Fire V440 Diagnostics And Troubleshooting Manual

For all the preceding reasons, the best practice is to leave the system console in its
default configuration.
You change the system console configuration by setting OpenBoot configuration
variables. See "Reference for System Console OpenBoot Configuration Variable
Settings" on page 196.
You can also set OpenBoot configuration variables using the ALOM system
controller. For details, see the Advanced Lights Out Manager (ALOM) Online Help.
Accessing the System Console Through a Graphics Monitor
The Sun Fire V440 server is shipped without a mouse, keyboard, monitor, or frame
buffer for the display of bitmapped graphics. To install a graphics monitor on the
server, you must install a frame buffer card into a PCI slot, and attach a monitor,
mouse, and keyboard to the appropriate back panel ports.
After starting the system, you might need to install the correct software driver for
the PCI card you have installed. For detailed hardware instructions, see "How to
Access the System Console via a Local Graphics Monitor" on page 192.
Note – Power-on self-test (POST) diagnostics cannot display status and error
messages to a local graphics monitor.
About the sc> Prompt
The ALOM system controller runs independently of the Sun Fire V440 server and
regardless of system power state. When you connect a Sun Fire V440 server to AC
power, the ALOM system controller immediately starts up, and begins monitoring
the system.
Note – To view ALOM system controller boot messages, you must connect an
alphanumeric terminal to the serial management port before connecting the AC
power cords to the Sun Fire V440 server.
You can log in to the ALOM system controller at any time, regardless of system
power state, as long as AC power is connected to the system and you have a way of
interacting with the system. You can also access the ALOM system controller prompt
