Preventing Electrostatic Discharge

Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are
improperly handled, results in complete or intermittent failures. We recommend use of an
ESD-preventive strap whenever you handle network equipment or one of its components.
Follow these guidelines for preventing ESD damage:

Caution When unpacking and setting parts aside, it is important to set them either in their original antistatic
packaging or on an antistatic mat to avoid ESD damage.

Do not wear loose clothing, jewelry, and other items that could get caught in the chassis while
working with the chassis and its associated components.
Use Cisco equipment in accordance with its specifications and product-usage instructions.
Do not work alone if potentially hazardous conditions exist.
Always use an ESD-preventive wrist or ankle strap, and ensure that it makes good skin contact.
Connect the equipment end of the connection cord to an ESD jack or bare metal surface on the
chassis.
Handle a card by its ejector levers, when applicable, or its metal carrier only; avoid touching the
board or connector pins.
Place a removed card board side up on an antistatic surface or in a static-shielding bag. If you plan
to return the component to the factory, immediately place it in a static-shielding bag.
Avoid contact between the card and clothing. The wrist strap protects the board from only ESD
voltage on the body: ESD voltage on clothing can still cause damage.
