Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) damage to circuit boards can oc cur if proper
grounding is not established. The boards can produce intermit tent or complete
failures if they are mishandled.
When handling circuit boards, observe the following guidelines to prevent ESD
damage:
•Always use an ESD-preventive ankle or wrist strap and ensure that the strap
makes adequate contact with your skin.
•The ankle or wrist strap protects equipment from ESD voltages on the body
only; ESD voltages on clothing can still cause damage to electronic
components.
Attaching an ESD-Preventive Strap
Attach an ESD antistatic strap to your body and to an open metal part of the
chassis on the Cisco XR 12406 Router (Figure 2-1).
