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 Hewlett Packard
Enterprise authorized reseller install the part.
NOTE:
For more information on static electricity, or for assistance with product installation,
contact your HP authorized reseller.
