5-2 Problem Solving
This chapter helps you identify and solve problems that may occur
during system installation or while using your system. The first section
of this chapter tells you how to reset your system in the event of
problems. The next few sections provide troubleshooting checklists and
procedural steps that help you isolate specific system problems. The
last section includes BIOS and system and disk status user
information.

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
!
CAUTION
Operating your system with the side panels removed can
damage your system components. For proper cooling and
airflow, always replace the side panels before powering on
your system.
Static Precautions
An electrostatic discharge (ESD) can damage disk drives, option boards,
and other components. You can provide some 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.
