Cisco Systems Cisco CRS-1 manual Preventing Electrostatic Discharge

Chapter 1 Overview

Preventing Electrostatic Discharge

Note Review the safety warnings listed in Regulatory Compliance and Safety Information that are applicable to your router before installing, configuring, or troubleshooting any installed card.

•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 MSCs, PLIMs, or their associated components.

•Cisco equipment operates safely when used in accordance with its specifications and product-usage instructions.

Preventing Electrostatic Discharge

Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are improperly handled, results in complete or intermittent failures. We recommend to use an ESD-preventive strap whenever you handle network equipment 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 a bare metal surface on the chassis.

•Handle a card by its ejector levers, when applicable, or the card’s metal carrier only; avoid touching the board or connector pins.

•Place a removed card 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 card and clothing. The wrist strap protects the board only from ESD voltage on the body; ESD voltage on clothing can still cause damage.
