ESD Damage Prevention
Anytime a service action involves physical contact with logic cards, modules,
back-panel pins, or other ESD sensitive (ESDS) parts, the service person must be
connected to an ESD common ground point on the product through the ESD wrist strap
and cord.
The ESD ground clip can be attached to any frame ground, ground braid, green wire
ground, or the round ground prong on the AC power plug. Coax or connector outside
shells can also be used.
Handling Removed Cards
Logic cards removed from a product should be placed in ESD protective containers. No
other object should be allowed inside the ESD container with the logic card. Attach tags
or reports that must accompany the card to the outside of the container.
