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:

Keep the work area clear and dust free during and after installation. Do not allow dirt or debris to
enter into any laser-based components.
Do not wear loose clothing, jewelry, or other items that could get caught in the router while working
with line cards.
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.
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.
