Electrostatic Discharge

142 Director 2/64 Installation Guide

Precautions Against 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.

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

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

Hewlett-Packard authorized service provider install the part.

Note: For more information on static electricity, or for assistance with product

installation, contact a Hewlett-Packard authorized service provider.
