Electrostatic Discharge

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 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.

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 a Compaq
authorized reseller install the part.

NOTE: For more information on static electricity or assistance with product installation, contact your
Compaq authorized reseller.
