Electrostatic Discharge Precautions
Static electricity collects on all nonconducting material, such as paper,
cloth, and plastic. An electrostatic discharge (ESD) can easily damage a
controller or other subsystem component even though you may not see
or feel the discharge. Follow these precautions whenever you’re
servicing a subsystem or one of its components:
n Always use an ESD wrist strap when servicing the controller or
other components in the subsystem. Make sure that the strap
contacts bare skin, fits snugly, and that its grounding lead is
attached to a bus that is a verified earth ground.
n Before touching any circuit board or component, always touch a
verifiable earth ground to discharge any static electricity that may
be present in your clothing.
n Always keep circuit boards and components away from
nonconducting material.
n Always keep clothing away from circuit boards and components.
n Always use antistatic bags and grounding mats for storing circuit
boards or components during replacement procedures.
n Always keep the ESD cover over the program card when the card is
in the controller. If you remove the card, put it in its original
carrying case. Never touch the contacts or twist or bend the card
while you’re handling it.
n Never touch the connector pins of a cable when it is attached to a
component or host.
