This chapter helps you identify and solve problems that may occur during
system installation or while using your system. The first part of this chapter tells
you how to reset your system in case of problems. The next several parts
provide troubleshooting checklists and procedural steps that help you isolate

status user information.

WARNING
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 cords are connected
between the system and an AC outlet. Before doing any
procedures, make sure that your system is powered off and
the power cords are unplugged 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 access cover removed can
damage system components. For proper cooling and airflow,
always replace the access cover 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.
Troubleshooting Checklists
The following provides troubleshooting checklists for problems that occur at
initial system startup, when you run new application software, and after the
system hardware and software were running correctly.
