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.

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
