Cisco Systems CISCO10720 manual Attaching an ESD-Preventive Strap

Page 31

Chapter 2 Preparing for Installation

Safety and Compliance

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 bare metal on the router chassis. (See Figure 2-1.)

•Attach an ESD-preventive wrist strap to your wrist, and to the chassis or to a bare metal surface. (See Figure 2-1.)

•The wrist strap protects equipment from ESD voltages on the body only; ESD voltages on clothing can still cause damage to electronic components.

Caution To avoid ESD damage to the equipment, periodically check the resistance value of the ESD-preventive wrist strap. The resistance measurement should be between 1 and 10 megohms (Mohms).

•When installing the card, confirm that the card is fully seated in the midplane and tighten the spring-loaded screws. These screws prevent accidental removal, provide proper grounding for the system, and help ensure that the connectors are seated in the midplane. (See Figure 2-1and the “Figure 3-6Disconnecting the Optical Interface Cable” section on page 3-6.)

•When removing the card, use the spring-loaded screws to unseat the card connector from the midplane. (See Figure 3-10and the “Figure 3-6Disconnecting the Optical Interface Cable” section on page 3-6.)

•Handle the card by the spring-loaded screws only; avoid touching the board or connector pins.

•Place the card board-side-up on an antistatic surface or in a static shielding bag. If you plan to return the card 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 voltages on the body; ESD voltages on clothing can still cause damage.
