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 recep-
tion. All HP 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:
NOTE: 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 digi-
tal apparatus does not exceed the Class A limits for radio noise
emissions from digital apparatusas set out in theRadio 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 require-
ments 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 there-
from.
Electrostatic Discharge (ESD) Precautions Electrostatic
charges can damage the integrated circuits on printed circuit
boards. To prevent such damage from occurring, observe the fol-
lowing precautions during board unpacking and installation:
• Stand on a static-free mat.
• Wear a static strap to ensure that any accumulated elec-
trostatic charge is discharged from your body to ground.
• Connect all equipment together, including the static-free
mat, static strap, routing nodes, and peripheral units.
• Keepuninstalledprintedcircuit boardsintheirprotective
antistatic bags.
• Handle printed circuit boards by their edges, once you
have removed them from their protective antistatic bags.
