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 use of an
ESD-preventive wrist 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 (Figure 2-5 and
Figure 2-6) or a bare metal surface on the chassis (ensure the chassis is grounded).
• Handle a card by its ejector levers, when applicable, or its 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 a card and clothing. The wrist strap protects the board from only ESD voltage
on the body; ESD voltage on clothing can still cause damage.
Figure 2-5 shows the ESD connection socket on the front side of the chassis.
