Electrostatic discharge

Attention: Electrostatic discharge (ESD) damage can occur when there is a difference in charge between the part, the product, and the service person. No damage occurs if the service person and the part being installed are at the same charge level as the product.

ESD damage prevention

Whenever 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 must be placed in ESD protective containers. No other object should be allowed inside the ESD container with the logic card. Attach all tags or reports that must accompany the card to the outside of the ESD container.
