ESD precautions

Before you begin any of the procedures, review the following precautions and preventive measures.

Preventing electrostatic discharge

To prevent electrostatic discharge (ESD) from damaging the system, be aware of the precautions to consider when setting up the system or handling parts. A discharge of static electricity from a finger or other conductor may damage system boards or other static-sensitive devices. This type of damage may reduce the life expectancy of the device.

CAUTION Parts can be damaged by electrostatic discharge. Follow these precautions:
  • Avoid hand contact by transporting and storing products in static-safe containers.
  • Keep electrostatic-sensitive parts in their containers until they arrive at static-protected workstations.
  • Place parts in a static-protected area before removing them from their containers.
  • Avoid touching pins, leads, or circuitry.
  • Always be properly grounded when touching a static-sensitive component or assembly.
  • Remove clutter (plastic, vinyl, foam) from the static-protected workstation.

Grounding methods to prevent electrostatic discharge

Several methods are used for grounding. Adhere to the following precautions when handling or installing electrostatic-sensitive parts.

CAUTION Parts can be damaged by electrostatic discharge. Use proper anti-static protection:
  • Keep the replacement CRU in the ESD bag until needed; and when removing a CRU from the enclosure, immediately place it in the ESD bag and anti-static packaging.
  • Wear an ESD wrist strap connected by a ground cord to a grounded workstation or unpainted surface of the computer chassis. Wrist straps are flexible straps with a minimum of 1 megohm (± 10 percent) resistance in the ground cords. To provide proper ground, wear the strap snug against the skin.
  • If an ESD wrist strap is unavailable, touch an unpainted surface of the chassis before handling the component.
  • Use heel straps, toe straps, or boot straps at standing workstations. Wear the straps on both feet when standing on conductive floors or dissipating floor mats.
  • Use conductive field service tools.
  • Use a portable field service kit with a folding static-dissipating work mat.

If you do not have any of the suggested equipment for proper grounding, have an authorized technician install the part. For more information about static electricity or assistance with product installation, contact customer support. For additional information, see www.dell.com/support.
