6.2Powering Off the System Unit

Caution –Prior to turning off the system unit power, exit from the operating system. Failure to do so may result in data loss.

Caution –Wear an antistatic wrist strap and use an ESD-protected mat when handling components. When servicing or removing system unit components, attach an ESD strap to your wrist, then to a metal area on the chassis, and then disconnect the power cord from the system unit and the wall receptacle. Following this caution equalizes all electrical potentials with the system unit.

To power off the system unit:

1.Back up system files and data.

2.Halt the system.

Caution –Pressing the front panel power switch does not remove all power from the system unit; a trickle voltage remains in the power supply. To remove all power from the system unit, disconnect the AC power cord.

3.Set the front panel power switch to the Off position (FIGURE 6-3).
