FCC Class A Compliance
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 users will be
required to correct the interference at their own expense.
You can determine whether your equipment is causing interference by turning it off. If the interference
stops, it was probably caused by the Cisco equipment or one of its peripheral devices. If the equipment
causes interference to radio or television reception, try to correct the interference by using one or more
of the following measures:

card into the network module or router chassis, you must turn off electrical power and disconnect
network cables.

Place a removed board component-side-up on an antistatic surface or in a static shielding container.
If you plan to return the component to the factory, immediately place it in a static shielding
container.
Avoid contact between the printed circuit boards and clothing. The wrist strap only protects
components from ESD voltages on the body; ESD voltages on clothing can still cause damage.
Never attempt to remove the printed circuit board from the metal carrier.
Turn the television or radio antenna until the interference stops.
Move the equipment to one side or the other of the television or radio.
Move the equipment farther away from the television or radio.
Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is,
make certain the equipment and the television or radio are on circuits controlled by different circuit
breakers or fuses.)
