The operating system warns other users of your system of the impending
shutdown, and then halts itself after a one-minute delay. If you wish to provide a
longer delay, see the man page for
shutdown(1)
.
The system responds with system halt messages followed by an
ok
prompt. When
the
ok
prompt appears, you can safely turn off the power in the proper sequence.
4. When the
ok
prompt appears, turn off the power to the system components in this
order:
1. System unit
2. Monitor
3. External drive units (if you have any)
6.1.2 When the System Does Not Respond Normally
To halt a system that is hung, or frozen, and unresponsive to commands:
1. If your system is on a network, wait a few minutes before proceeding.
Your system’s slow response may be due to network problems or delays. Check with
the person in charge of your network. If the response is not due to the network, go
to the next step.
2. Press Stop-a (or Break).
If you use a Wyse®™ WY-50™™, VT-100™™, or compatible terminal as the console
with your system unit, press Break instead of Stop-a.
