4 Sun Fire V215 and V245 Servers Administration Guide • September 2006
▼ To Power On the Server From the System
Controller
You can power on the server from the system controller by using the poweron
command at the SC console.
● To initiate the power-on sequence, issue the poweron command.
You see an sc> alert message on the system console. This indicates that the system
has reset.
Communicating With the System
To install your system software or to diagnose problems, you need some way to
interact at a low level with the system. The system console is Sun’s facility for doing
this. You use the system console to view messages and issue commands. There can
be only one system console per computer.
The serial management port (SER MGT) is the default port for accessing the system
console upon initial system installation. After installation, you can configure the
system console to accept input from and send output to different devices.
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.
After the operating system is booted, the system console displays UNIX system
messages and accepts UNIX commands.
Using the System Console
To use the system console, you need to attach an input/output device to the system.
Initially, you might have to configure that hardware, and load and configure
appropriate software as well.
