Removing and Installing a Line Card

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. Cisco recommends using an ESD-preventive strap
whenever you are handling network equipment or one of its components.
The following are guidelines for preventing ESD damage:
For safety, periodically check the resistance value of the ESD strap. The measurement should be

between 1 and 10 megohms.

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 ATM 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 ATM 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.
Avoid contact between the ATM line cards and clothing. The wrist strap only protects the board from
ESD voltages on the body; ESD voltages on clothing can still cause damage.
