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.
