Software Release 4.1
NOTE: Canopy products offer no software utility for alignment of APs or Backhaul timing
master modules.
4. Align the AP 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 Canopy 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 Canopy 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 that one or more APs require to each cover the intended 60° sector.
c. Apply the appropriate degree of downward tilt. (The Canopy System Calculator
page
DowntiltCalcPage.xls automatically calculates the angle of antenna
downward tilt that is required.)
d. Ensure that the nearest and furthest SMs that must register to this AP are within
the beam coverage area. (The Canopy System Calculator page
BeamwidthRadiiCalcPage.xls automatically calculates the radii of the beam
coverage area.)
5. Using stainless steel hose clamps or equivalent fasteners, lock the AP in the proper
direction and downward tilt.
One AP in each AP cluster must be connected to a CMM. For a module that is connected
to a CMMmicro, the Sync Input parameter in the Configuration web page must be
configured to Sync to Received Signal (Power Port). For a module that is connected to a
CMM2, the Sync Input parameter in the Configuration web page must be configured to
Sync to Received Signal (Timing Port).
6. For a single AP that is collocated with a CMM, connect the module to an Ethernet/Power
port on the CMM, as shown in Figure 25.
RESULT: When power is applied to a Canopy 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. See Diagnostic LEDs on
Page 62.
