Turning the computer off and on
Turning the computer off and on
Use the following procedures to turn the computer off and on.
Turning off the computer
1.Log in to the system as root.
2.Enter:
/usr/sbin/shutdown -y -i0 -g0
This shuts down the system. The ok prompt is displayed at the local console.
3.Press and release the front panel power button to turn off the system. Wait for the front panel Power/OK LED to turn off.
4.Turn the key switch to the Forced Off position. See the following figure.
! DANGER:
Be sure to turn the key switch to the Forced Off position before handling any internal components. Otherwise, it is possible for a user to restart the system remotely while you are working inside it. The Forced Off position is the only key switch position that prevents a Remote System Control (RSC) user from restarting the system.
5.Turn off the system monitor.
6.Turn off any external SCSI devices, starting with the device that is closest to the system and working toward the farthest device.
