Service Considerations; Read Cautions, Warnings, And Safety Precautions; Electrostatic Discharge Information; Generating Static - HP Xw6400 - Workstation - 4 GB RAM Reference Manual

CAUTION:
— Installing a processor incorrectly can damage the system board. Have an HP authorized reseller or
service provider install the processor. If you plan to install it yourself, read all of the instructions carefully
before you begin.
— Failure to follow the workstation preparation instructions and these result in an improperly installed
processor, causing extensive system damage.
— Processor socket pins are delicate and bend easily. Use extreme care when placing the processor
in the socket.
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.

Service considerations

The following sections discuss service considerations that should be reviewed and practiced before
removing and replacing any system components.
WARNING!
point. Lifting the workstation from the front bezel or lifting it incorrectly can cause the unit to fall and harm
you and damage the workstation. To properly and safely lift the workstation, lift it from the bottom of the
unit.

Read cautions, warnings, and safety precautions

For your safety, review the cautions, warnings, and safety precautions before accessing the workstation
components. Also, review the Safety and Regulatory Guide that came with your workstation for more
information.

Electrostatic discharge information

A sudden discharge of static electricity from your finger or other conductor can destroy static-sensitive
devices or microcircuitry. Often the spark is neither felt nor heard, but damage occurs. An electronic
device exposed to electrostatic discharge (ESD) might not appear to be affected at all and can function
normally for a while, but it has been degraded in the internal layers, reducing its life expectancy.
Networks built into many integrated circuits provide some protection, but in many cases, the discharge
contains enough power to alter device parameters or melt silicon junctions.

Generating static

The following table shows that different activities generate different amounts of static electricity. Static
electricity increases as humidity decreases.
