Regulatory Compliance Information and Safety
electrically connected to earth ground. Wear an ESD-preventive wrist strap,
ensuring that it makes good skin contact. Connect the clip to an unpainted surface
of the chassis frame to safely channel unwanted ESD voltages to ground. To
properly guard against ESD damage and shocks, the wrist strap and cord must
operate effectively. If no wrist strap is available, ground yourself by touching the
metal part of the chassis.
Caution For safety, periodically check the resistance value of the antistatic strap, which
should be between 1 and 10 megohms (Mohms).
FCC Class B Compliance
Note FCC Class B compliance applies only to the Cisco 1600 and Cisco 1700 series
routers, and to the Cisco ICS 7750. The Cisco 2600, Cisco 3600, and Cisco 3700
series routers are Class A compliant. See the platform regulatory compliance and
safety information documents for more information.
The equipment described in this document generates and may radiate
radio-frequency energy. If it is not installed in accordance with Cisco installation
instructions, it may cause interference with radio and television reception. This
equipment has been tested and found to comply with the limits for a Class B
digital device in accordance with the specifications in part 15 of the FCC rules.
These specifications are designed to provide reasonable protection against such
interference in a residential installation. However, there is no guarantee that
interference will not occur in a particular installation.
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:
• Turn the television or radio antenna until the interference stops.
• Move the equipment to one side or the other of the television or radio.
