Preventing Electrostatic Discharge
Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are
improperly handled, results in complete or intermittent failures. Electromagnetic interference (EMI)
shielding is an integral component of the line card. We recommend using an ESD-preventive strap
whenever you are handling network equipment or one of its components.
The 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 line cards.
Cisco equipment operates safely when it is 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
bare metal on the chassis.
Handle Ethernet line cards by the captive installation screws, the provided handle, ejector levers, or
the line card metal carrier only; avoid touching the board or connector pins.
Place removed Ethernet line cards 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.
