Warranty Statement

Hewlett-Packard products are warranted against defects in
materials and workmanship. For Hewlett-Packard Desktop
Computer Division products sold in the U.S.A. and Canada,
this warranty applies for ninety (90) days from the date of
delivery. * Hewlett-Packard will, at its option, repair or replace
equipment which proves to be defective during the warranty
period. This warranty includes labor, parts, and surface
travel costs, if any. Equipment returned to Hewlett-Packard
for repair must be shipped freight prepaid. Repairs
necessitated by misuse of the equipment, or by hardware,
software, or interfacing not provided by Hewlett-Packard are
not covered by this warranty.

HP warrants that its software and firmware designated by HP
for use with a CPU will execute its programming instructions
when properly installed on that CPU. HP does not warrant
that the operation of the CPU, software, or firmware will be
uninterrupted or error free.

NO OTHER WARRANTY IS EXPRESSED OR IMPLIED,
INCLUDING, BUT NOT LIMITED TO, THE IMPLIED
WARRANTIES OF MERCHANTIBILITY AND FITNESS FOR
A PARTICULAR PURPOSE. HEWLETI-PACKARD SHALL
NOT BE LIABLE FOR CONSEQUENTIAL DAMAGES.

Safety Considerations

General
This product and related documentation must be reviewed for familiarization with safety markings and
instructions before operation,

Safety Symbols
Instruction manual symbol: the product may be marked with this symbol. This refers the user
to the instruction manual in order to protect the product against damage,

Indicates hazardous voltages,

Indicates earth (ground) terminal (sometimes used in the manuals to indicate circuit common
connected to grounded chassis),

WARNING

The \" ARNING sign denotes a hazard. It calls attention to a procedure or
practice that, if not cOlTectiy performed or adhered to, could result in personal
injury. Do not pI'oceed beyond a \" ARNING sign until the indicated conditions
are fully undel'stood and met.

CAUTION

The CAUTION sign denotes a hazard. It calls attention to an operating
procedure or practice that, if not correctly performed or adhered to, could
result in damage to or destruction of part or alJ of the product Do not
proceed beyond a CAUTrON sign until the indicated conditions are fully
understood and met.

Grounding

WARNING

SAFETY EARTH GROUND - The computer on which this product is installed
is a safety class I product and is provided with a pJ'otecthre earthing terminal.
An uninterruptible safety earth ground must be pl'ovided from the main power
source to the product input wiring tel'minals, power cord, or supplied power cord
set. Whenever it is likely that the protection has been impaired, the product
must be made inoperative and be secured against any unintended operation.

BEFORE APPLYING POWER - Verify that the computer system is
configured to match the available main ()ower. Consult your system installation
manuals.

Servicing

WARNING

Any servicing, adjustment, maintenance, or repair of this product must be
performed only by service-trained personnel.

Handling

CAUTION

STATIC SENSITIVE DEVICES

When any two materials make contact, their surfaces are crushed on the
atomic level and electrons pass back and forth between the objects. On
separation, one surface comes away with excess electrons (negatively charged)
while the other is electron deficient (positively charged). The level of charge
that is developed depends on the type of material. Insulators can easily build
up charges in excess of 20,000 volts. A person working at a bench or walking
across a floor can build up a charge of many thousands of volts. The amount
of static voltage developed depends on the rate of generation of the charge
and the capacitance of the body holding the charge. [f the discharge happens
to go through a semiconductor device and the transient current pulse is not
effectively diverted by protection circuitry, the resulting current flow through
the device can raise the temperature of internal junctions to their melting
points. MOS structures are also susceptible to dielectric damage due to high
fields.

The resulting damage can range from complete destruction to latent
degradation. Small geometry semiconductor devices are especially susceptible
to damage by static discharge.

THIS PRODUCT CONTAINS STATIC SENSITI VE DEVICES.

Transport or store printed circuit board assemblies in an antistatic container.
When installing or removing the assemblies, do not touch any components.
Hold each board by its edges. Compol1ent replacement operations must be
performed at a static-free workstation using proper antistatic procedures.
