6-4 SPARCstation 5 Service Manual—November 1996
6
The operating system warns other users connected to your system from
the network 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 the
ok prompt. When the ok prompt appears, you can safely turn off the
power in the proper sequence.
6. When the ok prompt appears, turn off the power to the system
components in this order:
a. External drive units (if you have any)
b. System unit
c. Monitor
6.2 Powering On the System
Warning – Before turning on power to your system, be sure to close the system
unit. It is not safe to operate your SPARCstation while the system unit is open.
SPARCstation systems are equipped with a three-wire grounded power cord.
To reduce the risk of electrical shock, always plug the power cord into a
properly grounded power outlet.
Caution – Always allow 10 seconds between turning off the power and turning
it back on again. This pause prevents possible damage to power supply
components in your system unit.
To turn on power to the SPARCstation 5 system:
1. If your system uses external drive units, turn on the power to these units
first, starting with the unit that is furthest electrically from the system
unit.
2. Turn on the power to the monitor.
3. Turn on the power to the system unit.
