Powering Off the System
This section provides step-by-step instructions for powering down your
Model 745.
CAUTION: If you have an internal disk, do not turn off power to the system without first
shutting down the operating system software according to the following
procedure. Turning off the power for your system without first doing the
shutdown procedure may result in damage to data on your disk. Always
execute the shut-down process to completion first.
1 Exit all processes currently running.
2 Enter the following command to bring the system to a halted state
reboot -h
This gives a zero-length “grace period” before the system goes down to
the halted state.
3 After completing several shutdown procedures, the system eventually dis-
plays the following message:
Halted, you may now cycle power.
4 At this time the system no longer responds to keyboard input and you may
turn off the power. Turning the system back on initiates the boot sequence.
5 Once the operating system is shut down, press either the switch on the
front of the system or the switch on the rear of the system.
The green LED next to the switch is not lit, showing that the system
power is OFF.
If you want to shutdown and reboot automatically, instead of the above pro-
cedure, simply enter the reboot command with no options.
See reboot(1M) for various other options.
