How to Power Off the System

Before You Begin

Applications running on the Solaris OS can be adversely affected by a poorly executed system shutdown. Make sure that you have gracefully shut down any applications before powering off the system.

You can also use Solaris commands, the OpenBoot firmware power-offcommand, or RSC software to power off the system. For details, see:

■“How to Get to the ok Prompt” on page 126

■Sun Remote System Controller (RSC) User’s Guide

What to Do

1.Notify users that the system will be powered down.

2.Back up the system files and data, if necessary.

3.Ensure that the system control switch is in the Normal position.

4.Press and release the Power button on the system front panel. The system begins a graceful software system shutdown.

Note – Pressing and releasing the Power button initiates a graceful software system shutdown. Pressing and holding in the Power button for five seconds causes an immediate hardware shutdown. Whenever possible, you should use the graceful shutdown method. Forcing an immediate hardware shutdown may cause disk drive corruption and loss of data. Use that method only as a last resort.

5.Wait for the front panel Power/OK LED to turn off.

6.Turn the system control switch to the Forced Off position.
