238850-003.book Page 2 Friday, December 21, 2001 2:53 PM Removal and Replacement Preliminaries Plastic Parts Using excessive force during disassembly and reassembly can damage plastic parts. Use care when handling the plastic parts. Apply pressure only at the points designated in the maintenance instructions. Cables and Connectors 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.
238850-003.book Page 3 Friday, December 21, 2001 2:53 PM Removal and Replacement Preliminaries ■ Before handling a drive, ensure that you are discharged of static electricity. While handling a drive, avoid touching the connector. ■ Handle drives on surfaces that have at least one inch of shock-proof foam. ■ Avoid dropping drives from any height onto any surface. ■ After removing a hard drive, CD-ROM drive, or a diskette drive, place it into a static-proof bag.
238850-003.book Page 4 Friday, December 21, 2001 2:53 PM Removal and Replacement Preliminaries 4.4 Preventing Electrostatic Damage Many 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 the discharge contains enough power to alter device parameters or melt silicon junctions.
238850-003.book Page 5 Friday, December 21, 2001 2:53 PM Removal and Replacement Preliminaries ■ Place reusable electrostatic-sensitive parts from assemblies in protective packaging or non-conductive foam. ■ Use transporters and conveyers made of antistatic belts and roller bushings. Ensure that mechanized equipment used for moving materials is wired to ground, and that proper materials were selected to avoid static charging. When grounding is not possible, use an ionizer to dissipate electric charges.
238850-003.book Page 6 Friday, December 21, 2001 2:53 PM Removal and Replacement Preliminaries 4.7 Grounding Equipment and Methods Grounding equipment must include either a wrist strap or a foot strap at a grounded workstation. 4–6 ■ 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 snug against the skin at all times.
