Service Considerations; Read Cautions, Warnings, And Safety Precautions; Electrostatic Discharge Information - HP Xw9400 - Workstation - 16 GB RAM Reference Manual

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

of the workstation. Also, review the Safety and Regulatory Guide that came with your workstation for
more information.
WARNING!
three to five minutes for them to cool before opening the system access panels or touching internal
components.

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 work
perfectly throughout a normal cycle. The device 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.
