Solving Problems
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 user information.
Warning:
•
The DC push-button on/off switch on the front panel does not turn off
completely the system AC power. +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 cords from the
back of the chassis.
• Not disconnecting power before opening your system can result in
personal injury and equipment damage
• Running your system with the cover removed can damage your system
components.
• For proper cooling and airflow, always replace the covers 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 anti-static 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.
