Electrostatic discharge
Overview
To prevent damage to the system, be aware of the precautions you need to follow 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.
To prevent electrostatic damage, observe the following 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-free workstations.
• Place containers on a grounded surface before removing the contents.
• Avoid touching pins, leads, or circuitry.
• Always be properly grounded when touching a static-sensitive component or assembly.
Grounding methods
There are several methods for grounding. Use one or more of the following methods when handling or installing
electrostatic-sensitive parts:
• Use a wrist strap connected by a grounded cord. 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.
• Use heel straps, toe straps, or boot straps. 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 HP authorized reseller install the
part.
NOTE: For more information on static electricity or assistance with product installation, contact your HP
authorized reseller.
