CAUTION:
precautions while performing the system parts removal/replacement procedures:
— Work on a static-free mat.
— Wear a static strap to ensure that any accumulated electrostatic charge is discharged from your body
to the ground.
— Create a common ground for the equipment you are working on by connecting the static-free mat,
static strap and peripheral units to that piece of equipment.
NOTE:
HP accessories are for use in HP workstation products. They have been extensively tested for
reliability and are manufactured to high quality standards. HP, therefore, warrants only those
accessories that are manufactured or sold by HP.

Electrostatic discharge

Discharge of static electricity from a finger or other conductor can damage system boards or other static-
sensitive devices. This type of damage could reduce the life expectancy of the device.

Preventing electrostatic damage

To prevent electrostatic discharge damage, observe the following precautions:
Avoid hand contact by transporting and storing parts in static-safe containers.
Keep electrostatic-sensitive parts in their containers until they arrive at static-free work areas.
Place parts container on a grounded surface before removing parts from their container.
Avoid touching pins, leads, or circuitry of parts or workstations.
Always ensure you are properly grounded before touching an electrostatic-sensitive component or
assembly.

Grounding methods

There are several methods for grounding. Use one or more of the following measures when handling
or installing electrostatic-sensitive parts:
Use a wrist strap connected by a ground cord to a grounded workstation chassis. Wrist straps are
flexible straps with a minimum of 1 meg. ohm +/- 10 percent resistance in the ground cords. To
provide a proper ground, wear the strap snug against the skin.
Use heelstraps, toestraps, or bootstraps 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 dealer, reseller, or service
provider install the part.
NOTE:
For additional information on static electricity or for assistance with the installation of this
product, contact an authorized dealer, reseller, or service provider.
