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:
• 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.
Warning
For safety, periodically check the resistance value of the ESD strap. The measurement should be
between 1 and 10 megohms.
Required Tools and Equipment
You need the following tools and parts to remove and install ATM line cards:
• Flat-blade or Phillips screwdriver
• ESD-preventive wrist or ankle strap and instructions
• Interface cables to connect the ATM line card with another router or switch
See the “Fiber-Optic Network Interface Cables” section on page 24 for cable details.
