Safety and Regulatory Statements

See the Owner’s Guide that came with your system for safety informtion.

Emissions Regulations

Federal Communications Commission (FCC)

The Federal Communications Commission of the U.S. government regulates the radio

frequency energy emanated by computing devices through published regulations. These

regulations specify the limits of radio frequency emission to protect radio and television

reception. All HP Apollo nodes and peripherals have been tested and comply with these

limits. The FCC regulations also require that computing devices used in the U.S. display

the agency’s label and that the related documentation include the following statement:

NOTICE: This equipment has been tested and found to comply with the limits

for a Class A digital device, pursuant to part 15 of the FCC rules.

These limits are designed to provide reasonable protection against

harmful interference when the equipment is operated in a

commercial environment. This equipment generates, uses, and can

radiate radio frequency energy and, if not installed and used in

accordance with the instruction manual, may cause harmful

interference to radio communications. Operation of this equipment

in a residential area is likely to cause harmful interference in which

case the user will be required to correct the interference at his own

expense.

Canadian Department of Communications (CDC)

This digital apparatus does not exceed the Class A limits for radio noise emissions from

digital apparatus as set out in the Radio Interference Requirements of the Canadian

Department of Communications.

Preface

Emissions Regulations Compliance

Any third-party I/O device installed in HP system(s) must be in accordance with the

requirements set forth in the preceding Emissions Regulations statements. In the event

that a third-party noncompliant I/O device is installed, the customer assumes all

responsibility and liability arising therefrom.

Electrostatic Discharge (ESD) Precautions

Electrostatic charges can damage the integrated circuits on printed circuit boards. To

prevent such damage from occurring, observe the following precautions during board

unpacking and installation:

•Stand on a static-free mat.

•Wear a static strap to ensure that any accumulated electrostatic char

ge is

discharged from your body to ground.

•Connect all equipment together, including the static-free mat, static strap, routing

nodes, and peripheral units.

•Keep uninstalled printed circuit boards in their protective antistatic bags.

•Handle

printed circuit boards by their edges, once you have removed them from their

protective antistatic bags.

Installation Notice

Products designated in the applicable Hewlett-Packard price list as customer-installable

can be installed by computer-knowledgeable customers who carefully read and follow the

instructions provided. Customers who elect to have the product installed by our field

personnel are charged the applicable field installation charge, as covered under the

standard terms and conditions. For more information, please contact your local sales
