Static Precautions - NEC Express 5800 TM700 User Manual

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 troubleshoot-
ing checklists and procedural steps that help you isolate specific system problems. The
last section includes BIOS and system user information.
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 sys-
tem 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. Fail-
ure to disconnect power before opening your system can result
in personal injury and equipment damage
Operating your system with the cover removed can damage
your system components. For proper cooling and airflow,
always replace the right side panel 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.
