Grounding System
Direct grounding of the antenna mast, Avaya Wireless Outdoor Router bridge
and Avaya Wireless Surge Arrester is very important.
A safety grounding system is necessary to protect your Avaya Wireless Outdoor
installation from lightning strikes and the build-up of static electricity.
!
WARNING:
The antenna mast, Avaya Wireless Outdoor Router and Avaya Wireless
Surge Arrester must be connected to the same ground, using an
equipotential bonding conductor.
A good electrical connection should be made to one or more ground
rods, using at least a 10AWG ground wire and non-corrosive hardware.
The grounding system must comply with the National Electrical Code
and safety standards that apply in your country. Always check with a
qualified electrician if you are in doubt as to whether your
Avaya Wireless Outdoor installation is properly grounded.
Antenna Alignment
For optimal performance of your wireless link, make sure that the antennas are
properly aligned (facing one another “eye-to-eye”). To align the antennas:
■
Use a pair of binoculars and/or a map of the area and compass to point the
antennas to one another.
■
Use the Wireless Link Test option of the OR Manager as described in the
"Avaya Wireless OR Manager - User’s Guide" to analyze the radio link
quality.
The Wireless Link Test option will enable you to display the strength of the
Avaya Wireless radio signal related to the noise that may be appear in the
signal path.
Looking at the Wireless Link Test screen, you can interactively optimize
antenna alignment if required, by making small modifications in the antenna
orientation.
■
Alternatively, consult a professional Antenna Installation Service to optimize
the antenna alignment.
Omni-directional antennas are characterized by a wide radiation pattern.
Therefore alignment of this type of antennas is less critical than for directional
antennas.
