Electrostatic discharge alert You must observe proper grounding techniques to prevent the discharge of static electricity from your body into ESD sensitive components.
Packaging materials that contain ESD sensitive components are usually marked with a yellow and black warning symbol.
To avoid damaging ESD sensitive components:
Handle the components only after attaching a wrist strap to your bare wrist. Attach the other end of the wrist strap to a ground that terminates at the system ground, such as any unpainted metallic chassis surface.
Handle a circuit card by the faceplate or side edges only. See How to Hold a Circuit Card.
Keep components away from plastics and other synthetic materials such as polyester clothing.
Do not hand components to another person unless that person is grounded at the same potential level.
Hold devices such as a hard disk drives in the same manner as a large circuit card. The ESD sensitive area of these components is located on the bottom surface.
