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:
• 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.
To avoid damaging card mechanical components, never carry an Route Switch Processor (RSP), modular
port adapter, or line card by the captive installation screws or ejector levers. Doing so can damage these
components and cause card insertion problems.
Caution
• 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.
