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.
