CAUTION: Observe the following cautions when removing or replacing a processor:
— 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: To prevent damage to the workstation, observe the following Electrostatic Discharge
(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.
Service considerations
The following sections describe service considerations that you should review and practice before
removing and replacing system components.
WARNING! Do not use the front bezel as a handle or lifting point when lifting or moving the
workstation. Lifting the workstation from the front bezel, or lifting it incorrectly, could cause the
workstation to fall, causing possible injury to you and damage to the workstation. To properly and safely
lift the workstation, use the handles. If your workstation is not equipped with handles, lift from the bottom
of the workstation.
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.
ESD information
A sudden discharge of static electricity from your finger or other conductor can destroy static-sensitive
devices or microcircuitry. Often, the discharge is neither felt nor heard, but damage occurs nonetheless.
An electronic device exposed to 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.
