Precautions

Follow these precautions when you’re carrying out the procedures in this book.

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:

Always use an ESD wrist strap when servicing the controller or other components in the subsystem. Make sure that the strap contacts bare skin and fits snugly, and that its grounding lead is attached to a bus that is a verified earth ground.

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.

Always keep circuit boards and components away from nonconducting material.

Always keep clothing away from circuit boards and components.

Always use antistatic bags and grounding mats for storing circuit boards or components during replacement procedures.

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.

Do not touch the connector pins of a cable when it is attached to a component or host.

Component Precaution

System components referenced in this manual comply to regulatory standards documented herein. Use of other components in their place may violate country standards, negate regulatory compliance, or invalidate the warranty on your product.
