    Damage due to servicing that is not authorized by Dell is not covered by your warranty. Read and follow the safety instructions that came with the product.

  • Page 8: Electrostatic Discharge-Esd Protection

    ESD protection is an increasing concern. Due to the increased density of semiconductors used in recent Dell products, the sensitivity to static damage is now higher than in previous Dell products. For this reason, some previously approved methods of handling parts are no longer applicable.

  • Page 9: Transporting Sensitive Components

    It is recommended that all field service technicians use the traditional wired ESD grounding wrist strap and protective anti-static mat at all times when servicing Dell products. In addition, it is critical that technicians keep sensitive parts separate from all insulator parts while performing service and that they use anti-static bags for transporting sensitive components.

Due to the increased density of semiconductors used in recent Dell products, the sensitivity to static damage is now higher than in earlier Dell products. For this reason some previously approved methods of handling parts are no longer applicable.
  • Page 67 Figure 9. Intermittent (Latent) Damage to a Wiring Trace Do the following to prevent ESD damage: ● Use a wired ESD wrist strap that is properly grounded. The use of wireless anti-static straps is no longer allowed; they do not provide adequate protection. Touching the chassis before handling parts does not ensure adequate ESD protection on parts with increased sensitivity to ESD damage.
  • Page 68 Figure 11. ESD Field Service Kit The anti-static mat is dissipative and should be used to safely place parts on during service procedures. When using an anti-static mat, your wrist strap should be snug and the bonding wire should be connected to the mat and to bare-metal on the system being worked on.
  • Page 69 Table 27. Wrist Straps Wrist Strap and Bonding Wire Wireless ESD Strap (Unacceptable) ESD Wrist Strap Tester The wires inside of an ESD strap are prone to damage over time. When using an unmonitored kit, it is best practice to regularly test the strap prior to each service call, and at a minimum, test once per week.

Placement of Insulator Elements Unacceptable — DIMM lying on an insulator part (plastic Acceptable — DIMM separated from the insulator part heat sink shroud) Consider the Working Environment Before deploying the ESD Field Service kit, assess the situation at the customer location.
