Before You Begin
!
WARNING
The DC push button on/off switch on the front panel does
not turn off 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 performing
any procedures, first power off the DC push button switch
located on the front panel. Make sure your system is
powered off and the AC power cord is 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.
