Before You Begin
WARNING
The DC push-button on/off switch on the front panel does not turn off the system
AC power. Also, +5vdc is present on the system board whenever the AC power cord
is connected between the system and an AC outlet. Before doing the procedures in
this manual, make sure that your system is powered off and unplug the AC power
cord from the back of the chassis. 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.
