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.
