• Grounding methods
How to prevent electrostatic discharge
To prevent damage to the system, you must follow certain precautions 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 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 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 static-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.
