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:

Preventing Electrostatic Discharge
Required Tools and Equipment
Keep the work area clear and dust free during and after installation. Do not allow dirt or debris to
enter into any components.
Do not wear loose clothing, jewelry, or other items that could get caught in the router while working
with line cards or components.
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 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 a removed line 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 line card and clothing. The wrist strap only protects the board from ESD
voltages on the body; ESD voltages on clothing can still cause damage.
