Warning Because invisible laser radiation may be emitted from the aperture of the port when no cable is
connected, avoid exposure to laser radiation and do not stare into open apertures. Statement 70

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 and the modular port adapter. Cisco Systems, Inc.
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:

components and cause card insertion problems.

For safety, periodically check the resistance value of the ESD strap. The measurement should be

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.
Avoid touching card circuit boards or connector pins. When sliding cards in or out of slots, you
should handle them only by the front panel or metal card carrier.
When carrying a card, carry it only by the metal card carrier or inside a static shielding bag.
Place removed line cards or modular port adapters component-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 cards or modular port adapters and clothing. The wrist strap only
protects the board from ESD voltages on the body; ESD voltages on clothing can still cause damage.
