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 SPARCstation 5 system unit, press Break instead of Stop-a.
Note – If the system does not respond to the mouse and keyboard, pressing
Stop-a will not be effective. You may have to turn the power off, wait at least
10 seconds, and turn the power on again. Then try pressing Stop-a once more.
3. When the ok prompt appears, boot the operating system.
Enter boot at the ok prompt.
4. When you see the login prompt, log in to the system with your user
name and password.
5. Halt the operating system.
See the documentation supplied with your operating system for instructions
on how to halt it.
