Safety Notices
This equipment must be installed in compliance with local and national building codes, regulatory
restrictions, and FCC rules. For the safety of people and equipment, only professional network personnel
should install the equipment, cables, and antennas.
WARNING: Do not install the antennas near overhead power lines, electric light or power
circuits, or where it can come into contact with such circuits. Provide ten feet or more
clearance between the antenna and such power lines or circuits. Do not install the bridge
flush with the rooftop or wall. When installing the bridge, do not come into contact with
such circuits, which can cause serious injury or death. Follow local and national codes for
proper installation and grounding of antennas.
CAUTION: To comply with FCC radio frequency (RF) exposure limits, antennas should be
located at least two meters (six feet) or more from the bodies of all persons.
CAUTION: Do not install the bridge or connect and disconnect cables during periods of
lightning activity.
CAUTION: To avoid possible injury or damage to equipment, you must use either the
provided power supply or IEEE 802.3af compliant power supply equipment that is safety
certified according to UL, CSA, IEC, or other applicable national or international safety
requirements for the country of use. All references to power supply in this document refer
to equipment meeting these requirements.
CAUTION: It is the responsibility of the installer to ensure that the power over Ethernet (POE)
power supply is properly connected. Connection to any other device, such as a standard
Ethernet card or another POE supply, may result in permanent damage to equipment, electric
shock, or fire. Refer to the installation instructions for proper installation.
CAUTION: The 3Com power supply (part number 61-0107-000) input relies on a 16A rated
building fuse or circuit protector for short circuit protection of the line to neutral conductors.
CAUTION: If the antenna is installed outside, you need to use a lightning arrestor. 3Com
recommends the Huber Suhner lightning protector, item number 22652538. For more
information on this product, go to http://products.hubersuhner.com.
A lightning arrestor will not prevent damage from direct lightning strikes. It is extremely
important to ensure that the bridge is installed at least 1 meter (3 feet) below the top of the
grounded pole or mast.
CAUTION: Minimize damage from direct lightning strikes by mounting the antenna at least
1 Meter (3 feet) below the top of the mast.
