B Electrostatic discharge

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 may reduce the life expectancy of

the device.

Grounding methods

Preventing electrostatic damage

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 be properly grounded when touching a static-sensitive component or assembly. See

the next section.

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 assistance with product installation, contact your HP

authorized reseller.
