Safety Guidelines
You must take precautions to prevent electrostatic discharge (ESD).
•
Static Electricity – A charge stored in any body.
•
Electrostatic Discharge – A sudden transfer of electrostatic charge between bodies at different
electrostatic potential – usually as a spark as the bodies approach one another.
ESD is a major concern when handling components, especially expansion cards and system boards. Very
slight charges can damage circuits. Damage from ESD can occur immediately or it may not become
apparent for some time. ESD may also result in intermittent problems or a shortened product lifespan.
You can minimize the chances of a discharge by wearing the wrist‐grounding strap:
•
While the system is plugged into the Earth circuit via the power socket, attach the wrist‐grounding
strap to your wrist and clip the other end to a ground object. If a wrist‐grounding strap is not
available, you can discharge the static electricity in your body by touching an unpainted metal
surface, such as the computer chassis.
•
Unplug the system.
