Revision 2.0 General 3-13.1. GeneralThis chapter explains how to install and set up the FibeAir 1500 system. Forbest results, perform all operations in the sequence in which they arepresented in this chapter.3.2. Unpacking EquipmentThe FibeAir 1500 is shipped in 5 crates. Upon delivery, make sure that thefollowing items are included:■ Two indoor units and accessories■ Two outdoor units■ Two antennas and pole mounts■ One user manual■ One management software (CD).Unpack the contents and check for damaged or missing parts. Should therebe any parts that are damaged or missing, contact Giganet’s localdistributor.3.3. Site RequirementsThe first and most important consideration when choosing a prospective sitefor the ODU is that the point can provide an acceptable “line of sight” withthe opposing ODU. A site with a clear, unobstructed view is required.When considering a site, it is important to check for current and futureobstacles. Possible future obstacles are: trees, new buildings, windowcleaners on the roof, snow that may accumulate in front of the antenna, etc.The site should be accessible to certified personnel only.As with any type of construction, a local permit may be required beforeinstalling an antenna. It is the owner’s responsibility to obtain any and allpermits.
Chapter 3. Installation FibeAir 1500 Installation & Operation Manual3-2 Before Installing the ODU Revision 2.03.4. Before Installing the ODUDANGERWATCH FOR WIRES! Installation of this product near power lines isdangerous. For your own safety, follow these important safety rules.■ Perform as many assembly functions as possible on the ground.■ Watch out for overhead power lines. Check the distance to the powerlines before starting installation.■ Do not use metal ladders.■ If you start to drop the antenna or mast assembly, move away from itand let it fall.■ If any part of the antenna or mast assembly comes in contact with apower line, call your local power company. DO NOT TRY TO REMOVEIT YOURSELF! They will remove it safely.■ Make sure that the mast assembly is properly grounded.WARNING!Assembling antennas on windy days can be dangerous. Because of theantenna surface, even slight winds create strong forces. Be prepared tosafely handle these forces at unexpected moments. Giganet Ltd. is notresponsible or liable for damage or injury resulting from antennainstallation.3.5. Required Components and Equipment3.5.1. Required System ComponentsThe following FibeAir 1500 components are needed to install one radio link:■ Antenna mount and accessories■ Antenna■ ODU■ Cable■ Headset■ BNC headset adaptor■ BNC DVM adaptor.

Once you attain the highest audible tone, disconnect the BNC headsetadapter.This completes the initial alignment of the system.3.10.3. Alignment Verification − Checking Actual Receive LevelWhen pivoting the antenna ±2° in azimuth and elevation during antennaalignment, three distinct lobes are probable: the two side lobes and thecenter (main) lobe. To ensure optimum system performance, the centerlobe of the antenna must be aligned with the center of the opposing antennain the link.The initial alignment procedure explained in the previous section allows youto align the system to the peak of a lobe. However, it is difficult to make surethat the system is aligned to the center lobe using the tone heard throughthe headset. Therefore, following the initial alignment procedure you mustperform the final alignment verification explained below in order to makesure that the system is aligned to the center lobe by verifying that the actualreceived signal level corresponds to the expected receive signal level.When the antenna is aligned to a side lobe, the expected RSL is at least25dB less than the calculated unfaded RSL.Loosen nuts andadjust elevationLoosen nuts
Chapter 3. Installation FibeAir 1500 Installation & Operation Manual3-36 Installation Instructions Revision 2.0Figure 3-35 Antenna Alignment − Main and Side Lobes1. Connect a DVM (Digital Voltmeter) - BNC adapter to the ODU.2. Set the DVM to 2 VDC.3. Turn the DVM on.The reading on the DVM indicates receive signal level.For example, if -1.44V is displayed, receive signal level is -44 dBm.4. Compare the value displayed on the DVM to the expected valuedetermined in section 3.9.11, step 2.5. If the received signal level matches the expected level, tighten all boltedjoints and remove the safety assembly.ImportantIt is important to verify that the antenna is aligned to the center lobepeak. Proper alignment reduces the sensitivity to antenna movement,which can be due to strong winds or any other forces.3.10.4. Final CheckWhen the antenna is installed, make sure that all aspects of the installationinstructions have been followed. Check that all bolted joints are tightlylocked, and connect and cover the coax cable connector as follows:1. Connect the coaxial cable between the IDU and ODU using theN-Type connector on the IDU and the ODU.
FibeAir 1500 Installation & Operation Manual Chapter 3. InstallationRevision 2.0 Installation Instructions 3-372. Make sure that the fittings and the coax cable are clean and dry.3. Peel approximately 6 inches of COAX-SEAL from the paper backing.4. Wrap isolation tape over the coax cover. Start winding from coax covertowards fitting with one half overlap with each winding making sure alljoints are well covered.Figure 3-36 Steps 1, 2 & 35. After entire fitting and coax cable are covered with approximately 3/16"thick layers, mold and form COAX-SEAL with fingers to make a smoothsurface and force out any air.Figure 3- 37 Step 46. If more COAX-SEAL is necessary to complete seal simply cut theneeded amount and add to existing COAX-SEAL, molding and press intothe other material. COAX-SEAL adheres to itself with slight pressure.Carefully inspect seal to make certain that all joints are covered

Safety and GroundingThe pole, antenna mount assembly and feed cables must be grounded inaccordance with current national and local electric codes to protect fromsurges due to nearby lightning strikes. The following figure illustrates atypical grounding method.Clamps that provide a solid connection between ground wire and groundsource should be used.Figure 3-38 Grounding the ODU AssemblyThe ODU installation and initial alignment is now complete. Repeat thisprocedure for the opposing ODU.

Using the Headset and BuzzerConnect a headset to the headset connector on the IDU (both sides), verifycommunications and test the buzzer (also on IDU front panel). Note that touse the headset, the Engineering Order Wire option must be set to active.The Engineering Order Wire is an audio connection between the two indoorunits.3.11.1.1. Verifying Activation of Engineering Order Wire (EOW)To verify that the Engineering Order Wire (EOW) option is activated, followthese steps:1. Select Configuration ½ Sonet/SDH.The Sonet/SDH Configuration window is displayed.Figure 3-39 Sonet/SDH Configuration Window2. In the first line of the RSOH Function section of the window, next toEOW, click on Active (radio button should be filled ♦).3. Click Apply.4. Click Cancel.The Sonet/SDH Configuration window is closed and you are returned tothe Work Area window.

Select Configuration ½ ODU.The ODU Configuration window is displayed.Figure 3-41 ODU Configuration Window2. Verify that the remote side of the ODU Configuration window is active(values can be changed).3. Verify that the Monitored Rx displayed is as previously measured by theDVM (Unfaded RSL).If any problems were encountered during the checks described above, referto Chapter 6 - Troubleshooting & Diagnostics.
