Powering On the System

Caution – 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.
Caution – These devices are equipped with a 3-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.
After turning off the power to replace a part, restarting the system is relatively
simple:
1. Reconnect the cables.
See Section 7.5 "Reconnecting the External Cables" on page 7-7.
