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:

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 SIPs 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 SIPs 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 SIPs and clothing. The wrist strap only protects the board from ESD
voltages on the body; ESD voltages on clothing can still cause damage.
