Before You Begin

Observe all cautions, warning, and static precautions while working with your
system and while performing any procedures.
The DC push button on/off switch on the front panel does
not turn off system AC power. Also, +5 Vdc is present on the
system board whenever the AC power supply cords are
connected between the system and AC outlets. Before
performing any procedures, first press off the DC push
button switch located on the front panel. Make sure your
system is powered off and all AC power cords are
unplugged from the system. Failure to disconnect power
before opening your system can result in personal injury and
equipment damage.

Static Precautions

An electrostatic discharge (ESD) can damage disk drives, option boards, and
other components. You can provide ESD protection by wearing an antistatic
wrist strap attached to chassis ground when handling system components.
Electronic devices can be easily damaged by static electricity. To prevent
damage, keep them in their protective packaging when they are not installed in
your system.
