Preventing Electrostatic Discharge Damage
Many of the components discussed in this chapter are sensitive to electrostatic discharge (ESD) damage,
which can occur when electronic cards or components are handled improperly, results in complete or
intermittent failures.
To prevent ESD damage, follow these guidelines:
•
Always use an ESD wrist or ankle strap and ensure that it makes good skin contact.
•
Connect the equipment end of the strap to an unfinished chassis surface.
•
Place the removed memory card on an antistatic surface or in a static shielding bag. If the card will
be returned to the factory, immediately place it in a static shielding bag.
•
Avoid contact between the card and clothing. The wrist strap protects the card from ESD voltages
on the body only; ESD voltages on clothing can still cause damage.
•
Do not remove the wrist strap until the installation is complete.
Cabling Guidelines
Follow these guidelines for using cables with the router:
•
Position cables so that they do not place strain on the router connectors.
•
Organize cables into bundles when necessary to avoid intertwining.
•
Inspect cables to ensure adequate routing and bend radius.
•
Install cable ties that comply with your site requirements.
