    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 7: Safety Precautions

    Standby Power Dell products with standby power must be completely unplugged before the case is opened. Systems that incorporate standby power are essentially powered while turned off. The internal power enables the system to be remotely turned on (wake on LAN), suspended into a sleep mode, and have other advanced power management features.
  • Page 8 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 For this reason some previously approved methods of handling parts are no longer applicable.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 9 • Handle all static-sensitive components in a static-safe area. If possible, use anti-static floor pads and workbench pads. • When handling static-sensitive components, grasp them by the sides, not the top. Avoid touching pins and circuit boards. • When unpacking a static-sensitive component from its shipping carton, do not remove the component from the anti-static packing material until you are ready to install the component.
  • Page 10 Table 1. 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.
  • Page 11 Table 2. 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. For example, deploying the kit for a server environment is different than for a desktop or portable environment.
  • Page 12 Figure 7. ESD Packaging Transporting Sensitive Components When transporting ESD-sensitive components such as replacement parts or parts to be returned to Dell, it is critical to place these parts in anti-static bags for safe transport. ESD Protection Summary It is strongly suggested that all field service engineers use the traditional wired ESD grounding wrist strap and protective anti-static mat at all times when servicing Dell products.
