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 SPARC system while the system unit is open.
Caution – These devices 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 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.
