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 GRP. Cisco recommends using a ESD-preventive strap whenever you are handling a router or one of its components.

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 router chassis.

•Handle the GRP by the card carrier and by the left-side spring-loaded screw (horizontal view). Avoid touching board components or connector pins.

•Place a removed GRP 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 GRP and clothing or jewelry. The wrist strap protects the board only from ESD voltages on the body; ESD voltages on clothing or jewelry can still cause damage.

Working with Electrical Equipment

Follow these basic guidelines when working with any electrical equipment:

•Before beginning any procedure requiring access to the chassis interior, locate the emergency power-off switch for the room in which you are working.

•Disconnect all power and external cables before moving a chassis.

•Do not work alone when potentially hazardous conditions exist; never assume that power has been disconnected from a circuit; always check.

•Do not perform any action that creates a potential hazard to people or makes the equipment unsafe.

•Carefully examine your work area for possible hazards such as moist floors, ungrounded power extension cables, and missing safety grounds.
