Electrostatic Discharge
Electrostatic discharge (ESD) is a common problem and may cause data loss,
system down time, and other problems. The most common source of static
electricity is the movement of people in contact with carpets and clothing. Low
humidity also increases the amount of static electricity. You must discharge all
static electricity prior to touching electronic equipment. Follow the precautions in
the “Electrostatic Discharge Precautions” given in the Preface whenever you are
installing any component.
