System Shut-down
The shutdown or init command is executed by the super user to change the
operational state of the machine. By default, it brings the system to a state where
only the console has access to the operating system.
The shutdown command sends a warning message and a final message before it
begins shutdown activities. Refer to shutdown(1M) and init(1M) for further
information.
You can also use the following commands:
After shutting down the system, move the ON/STBY switch at the front of the
system cabinet to the STBY position and immediately release it.
To start the system again and begin the automatic booting sequence, you must set
the ON/STBY switch to the ON position and immediately release it.
