Electrostatic discharge information
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 products in static-safe containers such as conductive tubes,
bags, or boxes.
• Keep electrostatic-sensitive parts in their containers until they arrive at static-free stations.
• Cover workstations with approved static-dissipating material. Provide a wrist strap connected to
the work surface and properly grounded (earthed) tools and equipment.
• Keep work area free of nonconducting materials such as ordinary plastic assembly aids and
foam packing.
• Place parts on a grounded surface before removing them from their containers.
• Avoid touching pins, leads, or circuitry.
• Make sure that you are properly grounded when touching a static-sensitive component or
assembly.
• Place hard drives with the Printed Circuit Board (PCB) side down.
• Use conductive field service tools.
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% 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 Authorized HP
Reseller install the part.
NOTE:
For more information on static electricity or assistance with product installation, contact your HP
Authorized Reseller.
