2.1 How to Power Off the System
Caution - Before turning off system power, halt the operating system as described
below. Failure to halt the operating system properly can result in loss of disk drive
data.
Note - If the system "hangs" and you cannot issue an operating system command to
turn the system power off, turn the keyswitch to the Standby position. This turns off
power to all internal system components. For further information on keyswitch
positions, see Section 2.9.1 “Keyswitch Settings” on page 72.
2.1.1 What to Do
1. Notify users that the system will be powered down.
2. Back up the system files and data, if necessary.
3. Halt the operating system using the appropriate commands.
Refer to the Solaris Handbook for Sun Peripherals that corresponds to your
operating system.
4. Wait for the system halt messages and the ok prompt.
5. Turn the keyswitch on the front panel of the system to the Standby position.
