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 to use an
ESD-preventive strap whenever you handle network equipment or one of its components.
Following are guidelines for preventing ESD damage:

Keep the work area clear and dust-free during and after installation. Do not allow dirt or debris to
enter into any laser-based components.
Do not wear loose clothing, jewelry, or other items that could get caught in the router while working
with MSCs, PLIMs, or their associated components.
Cisco equipment operates safely when used in accordance with its specifications and product-usage
instructions.
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 connection socket on the router or to
a bare metal surface on the chassis.
Handle a card by its ejector levers, when applicable, or the card's 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 only from ESD
voltage on the body; ESD voltage on clothing can still cause damage.
