How to Power Off the System
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 front panel keyswitch is in the Normal or Diagnostics 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 this method only as a last resort.
5. Wait for the front panel Power/OK LED to turn off.
6. Turn the keyswitch fully counterclockwise to the Forced Off position.
