8. Align the BHM as follows:
a. Move the module to where the link will be unobstructed by the radio horizon
and no objects penetrate the Fresnel zone. (The Cyclone System Calculator
page AntennaElevationCalcPage.xls
automatically calculates the minimum
antenna elevation that is required to extend the radio horizon to the other end
of the link. The Cyclone System Calculator page FresnelZoneCalcPage.xls
automatically calculates the Fresnel zone clearance that is required between
the visual line of sight and the top of a high-elevation object.)
b. Use a local map, compass, and/or GPS device as needed to determine the
direction to the BHS.
c. Apply the appropriate degree of downward or upward tilt. (The Cyclone
System Calculator page DowntiltCalcPage.xls
automatically calculates the
angle of antenna downward tilt that is required.)
d. Ensure that the BHS is within the beam coverage area. (The Cyclone System
Calculator page BeamwidthRadiiCalcPage.xls
automatically calculates the
radii of the beam coverage area.)
9. Using stainless steel hose clamps or equivalent fasteners, lock the BHM into
position.
10. Remove the base cover of the BHM. (See Figure 46 on Page 178.)
11. If this BHM will not be connected to a CMMmicro, optionally connect a utility
cable to a GPS timing source and then to the RJ-11 port of the BHM.
12. Either connect the BHM to the CMM or connect the DC power converter to the
BHM and then to an AC power source.
RESULT: When power is applied to a Cyclone module or the unit is reset on the
web-based interface, the module requires approximately 25 seconds to boot.
During this interval, self-tests and other diagnostics are being performed.
13. Access the General tab of the Configuration page of this BHM.
