  • Page 47: Cables And Connectors

    Cables and connectors CAUTION: When servicing the computer, be sure that cables are placed in their proper locations during the reassembly process. Improper cable placement can damage the computer. Cables must be handled with extreme care to avoid damage. Apply only the tension required to unseat or seat the cables during removal and insertion.

  • Page 48: Grounding Guidelines

    Grounding guidelines Electrostatic discharge damage Electronic components are sensitive to electrostatic discharge (ESD). Circuitry design and structure determine the degree of sensitivity. Networks built into many integrated circuits provide some protection, but in many cases, ESD contains enough power to alter device parameters or melt silicon junctions. A discharge of static electricity from a finger or other conductor can destroy static-sensitive devices or microcircuitry.

  • Page 49: Packaging And Transporting Guidelines

    Packaging and transporting guidelines Follow these grounding guidelines when packaging and transporting equipment: ● To avoid hand contact, transport products in static-safe tubes, bags, or boxes. ● Protect ESD-sensitive parts and assemblies with conductive or approved containers or packaging. ● Keep ESD-sensitive parts in their containers until the parts arrive at static-free workstations.

  • Page 50: Equipment Guidelines

    Equipment guidelines Grounding equipment must include either a wrist strap or a foot strap at a grounded workstation. ● When seated, wear a wrist strap connected to a grounded system. Wrist straps are flexible straps with a minimum of one megohm ±10% resistance in the ground cords. To provide proper ground, wear a strap snugly against the skin at all times.

  • Page 51: Unknown User Password
