C Electrostatic discharge and grounding recommendations
Electrostatic discharge recommendations
CAUTION: To prevent damaging 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 can
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 parts on a grounded surface before removing them from their containers.
• Avoid touching pins, leads, or circuitry.
• Always make sure you are 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 ground cord to a grounded workstation or 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.
• 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 HP authorized reseller install
the part.
NOTE: For more information on static electricity, or for assistance with product installation,
contact your HP authorized reseller.
