1027145–0001 Revision D 3–2 Installing mast mounts Hub installationTypically, the installers assemble a nonpenetrating roof mount foreach ODU to be installed. In some cases, a different type of mastmount may be used, or an existing structure may be used.The mount supports the mast in a vertical position, and the ODU ismounted on the mast, as shown in figure 3-1.Figure 3-1 Mast mount supporting mast and ODUT00060013.1Overview
1027145–0001 Revision D Installing mast mounts 3–3Hub installationDANGERIf you have to walk on a roof or use a ladderto access an installation site or equipment,follow these precautions to prevent personalinjury or death:•Do not walk near the edge of the roof.•Watch out for overhead power lines.Stay at least 6 meters (20 feet) frompower lines.•Walk only on sound roof structures.•Do not work on a roof or ladder inhigh wind, rain, lightning, or otheradverse weather conditions.•Follow all safety precautions from theladder or antenna manufacturer.•Do not walk on a roof if a storm isvisible—even if the storm is distant.Lightning can travel and strike inadvance of a storm.Site preparation personnel specify the ODU location as part ofpreparing the hub rooftop drawing.1. Use the hub rooftop drawing to determine where to installthe ODU.2. Make sure the roof penetration or entry point for the IFL issuitable.Important: The location(s) used for ODU installation must meetthe requirements listed in the Hub and Remote Terminal SitePreparation Guide. Key considerations include:•Line of sight•IFL entry location•Sources of interference•Safety•Ground point location•Access•SecurityFor details, see the Site Preparation Guide.3.2Roof and laddersafety3.3Mount location
1027145–0001 Revision D 3–4 Installing mast mounts Hub installationDepending on the installation location, you may have to hoist themount kit, ballast (concrete blocks), IFL cable, and tools to therooftop as shown in figure 3-2. Using two or more people for thistask will save considerable time.hbph001Figure 3-2 Hoisting materials to the installation locationWARNINGIf you need to hoist materials to theinstallation location, observe theseprecautions to avoid personal injury:•Use a rope strong enough to supportall of the materials that need to behoisted.•Never stand under the rope whilematerials are being hoisted.•Hoist one concrete block at a time.•Pass the rope through the center holeof each concrete block. If you use thehole on either end, the end can breakoff, allowing the concrete block to fall.•Be advised that the contents of themount kit can fall through the end ofthe box if the box is tilted—especiallyif the box has been damaged.•Use a back brace.If possible, avoid hoisting the ODU transceiver and antenna on arope. If possible, carry these components in a backpack or paddedbag.3.4Handling materials
1027145–0001 Revision D Installing mast mounts 3–5Hub installationMany roof types are suitable for AIReach Broadband ODUinstallations. Mount installation procedures for the followingcommon roof types are described later in this chapter:•Rubber cap sheet/glued rubber cap sheet•Loose gravel on rubber cap sheet•Corrugated metalThe roof type is a factor in the type of mast mount selected. Also,some mount installation steps may be different, depending on theroof type.The following options are available for mounting a mast tosupport the ODU:•Nonpenetrating roof mount – This mount, essentially aflat platform assembled from a kit, is suitable for mostapplications. It can be used on various flat roof types. Fordetails, see section 3.7.•Existing structure – An existing structure such as anantenna tower can be used as a mast, or a mast can bemounted to the structure, if the structure meets therequirements given in the Hub and Remote Terminal SitePreparation Guide.3.5Roof types3.6Mast mount types
1027145–0001 Revision D 3–6 Installing mast mounts Hub installationThe standard nonpenetrating roof mount, HNS 9200375–0001, is aflat, metal–frame mount assembled from a kit. It requires a6.5–by–6.5–foot space (1.98 by 1.98 meters) and includes a 7–foot(2.1–meter) mast. You install the mount on a rubber pad; concreteblocks are added for ballast.The standard mount can be used on a variety of flat roof types, asdetailed below.Instructions are given below for various types of roofs. See alsothe manufacturer’s instructions, which are included in the mountshipping carton.Most flat roofs are topped with:•Glued rubber cap sheet or•Rubber cap sheet with gravelFollow these instructions for either type of roof:1. If the cap sheet is covered with gravel, use a push broom orsnow shovel to clear the gravel from the area where themount will be installed, as shown in figure 3-3.hbph005Figure 3-3 Clearing gravel from the installation location2.

Place the concrete blocks on the mount so they are evenlyspaced, with the ends of each block anchoring both theinner and outer base angles, as shown in figure 3-9.Figure 3-9 Proper placement of concrete blocks on the mountrtph01010. When the mount installation is complete, if the roof iscovered with gravel, replace gravel up to the outside edgesof the mount. See figure 3-9.Do not replace gravel in the area inside the mount base.Leave the rubber pad exposed.This section explains how to install the standard nonpenetratingroof mount on a corrugated metal roof.Special requirements:•Pressure treated lumber, as specified in step 1 below,and•Twelve 1–inch–long (2.5–centimeter) lag bolts.1. Obtain five pieces of pressure treated lumber, each 4 inchesby 4 inches by 8 feet long (10 centimeters by 10 centimetersby 2.44 meters long).2. Important: Select an area of the roof that is supported by ametal I–beam to install the mount.3. Cut the rubber pad into strips 4 inches wide by 8 feet long(10 centimeters wide by 2.44 meters long).4. Use 5–penny shingle nails to nail one strip of rubber pad toone surface of each piece of lumber. See figure 3-10.Corrugated metal

Failure to observe thesewarnings could result in personal injury ordeath.WARNINGPotential radio frequency (RF) hazard:•Keep away from the front of theoutdoor unit (ODU) antenna while theODU is operating. Note that you cannottell from outward appearance whetherthe ODU is operating or not.•Be careful with respect to the ODU youare installing and ODUs that mayalready be operating in the installationarea.Failure to observe these warnings couldresult in injury to eyes or other personalinjury.Safety warnings
1027145–0001 Revision D Installing ODUs 4–5Hub installationBefore you can install the outdoor equipment, the mast must beinstalled.The mast must have an outside diameter of 2.0 to 4.5 inches (5.0to 11.4 centimeters) and must be securely mounted in a vertical orhorizontal position. If the mast is not installed, you will need toinstall it before you proceed. For additional details concerningthe mast, see the AIReach Broadband Hub and Remote TerminalSite Preparation Guide.Before starting, make sure you have:•Antenna mount•Antenna•Transceiver•3/8–inch torque wrench with 13–millimeter deep socket•5/32–inch (4–millimeter) hex key wrench You will also need the following tools to plot HT alignments:•Detailed local map – Must show true north, streets,buildings, and landmarks. It is helpful if the map showsmagnetic declination, or magnetic north versus true north. AU.S. Geological Survey map is recommended. A travel mapwill suffice if it shows sufficient detail.•Ruler or straight edge•Protractor with markings from 0° to 180°.•Pencil or broad–tip pen•Compass•Chalk or other marker to mark lines on the roof•Optional: chalked plumb line (the type you snap toleave a straight chalk line)Unpack the ODU transceiver and antenna before going up to theroof. Carry the transceiver and antenna to the roof (in separatetrips) in a backpack or padded bag. Make sure the transceiver orantenna is secured in the backpack or bag.Prerequisites4.2Transporting theODU
1027145–0001 Revision D 4–6 Installing ODUs Hub installationTo install and align the ODU, you must know the assigned HTalignment direction and where this direction is relative to the HTlocation. Plot the planned sectors on a local map as explained inthis section—then you will know the alignment direction for eachHT to be installed.1. Obtain the HT alignment direction for each HT to beinstalled (for example, 45°, 135°, and so on) from the SiteData Record (prepared by the site survey team).2. Find true north on the map.3. Find the hub site on the map, and clearly mark its location.4. Carefully plot lines for true north (0°), south, east, and west,with the hub site at the intersection, as shown in figure 4-3(page 4–7).5. Plot the assigned alignment direction for each sector, andidentify the sectors, using figure 4-3 as an example.Figure 4-3 shows four sectors for 90° ODUs. Sectors for45° or 22.5° ODUs are 45° and 22.5° wide, respectively. Insome cases, a full 360° coverage range is not required.6. On the roof, determine where true north is.You may be able to determine true north using only the mapand landmarks.If you use a compass to determine magnetic north, youmust adjust for magnetic declination (deviation fromtrue north) to determine true north. Some maps showmagnetic declination; some show magnetic north versustrue north.If you are west of the north–to–south line where declinationis 0°, the declination is east (or positive). If you are east ofthe 0° declination line, the declination is west (or negative).To correct a magnetic compass reading to true north,subtract east (positive) declination values from themagnetic north reading. Add west (negative) declinationvalues. For example:S If the declination is east, 14°, subtract 14° from themagnetic reading.S If the declination is west, –14°, add 14° to themagnetic reading.4.3Determining the HTalignment direction

1027145–0001 Revision D 4–8 Installing ODUs Hub installationMagnetic declination changes over time, so use only currentdeclination values.A compass on a roof may be unreliable, due to metalreinforcing rods in concrete and other metal. Stay awayfrom metal if possible. Take several readings. If readingsare not consistent, take readings on the street and mark truenorth (accounting for declination) on the street where youcan see it from the roof. Use a compass only forverification; do not rely on a compass alone to align theantenna.It may be helpful to mark true north, south, east, and weston the roof using a chalked plumb line or some othermarking method.Once you know true north (0°) you can easily determinesouth, east, and west (at 90° intervals), as shown in figure4-3. You can use the map, protractor, and landmarks todetermine any other direction (angle) on the map or withrespect to the actual site.With true north, south, east, and west known, you can alignall HTs at the hub site. You could align them on the basis oftrue north alone, but knowing the other three directions isuseful for reference and verification.7. Use the map and landmarks to verify the directions youhave determined.8. Place the protractor on the map, with its 0° (zero degree)mark on true north. Then determine and plot the angle(s)that corresponds to the HT alignment direction(s).
1027145–0001 Revision D Installing ODUs 4–9Hub installation9. Using the map, directional markings you have made on theroof, the protractor, and landmarks, point the center of theantenna toward the HT alignment direction (i.e., toward thecenter of the sector, or coverage area) as you install theantenna. (See figure 4-4. Installation instructions for theantenna are covered in sections 4.4 through 4.9.)Each sector is defined by a sector angle and coverage angle,as illustrated in figure 4-4. However, to align the antenna,you only need to know the assigned HT alignmentdirection.Figure 4-4 HT sector definition and terminologyThis exampleshows a singlesector fora 45 ODU.°hb082Sector angle - Starting point for thecoverage angle, relative to 0° (north)Coverage angle - Sector coverage (beamwidth)HT alignment direction+22.5:Sector angle 30.0+ 1/2 coverage angle= 52.5°°°52.5°30°Truenorth0°45°Sector (shaded area)ODU22.5°Keep the sector map and protractor handy.

Swing the clamp toward the interface until you can“capture” the clamp by swiveling the free–swinging boltsinto the two slots in the clamp, as shown in figure 4-11.The elevation adjustment arm (shown in figure 4-11) mustbe behind the antenna (not installed yet). This means it willbe on the side of the interface that is farthest from the HTalignment direction (sector direction).In some cases, to align the antenna in the right direction, itis necessary to install the mount upside down, with theelevation adjustment arm at the top of the mast interface.This is acceptable, as long as the mount is installed so theelevation adjustment arm will be behind the antenna.4. Align the mast interface and temporary installation collar sothe rectangular face of the interface is parallel with the flatsurface of the collar, as shown in figure 4-11.5. Finger tighten the four mast clamp nuts so the mastinterface and permanent mast clamp are snug and withoutexcess movement.You should be able to smoothly pivot the mast interfaceand mast clamp around the mast to permit coarse azimuthadjustment.(You fully tighten the mast clamp nuts later, aftercompleting all adjustments.)

Using a torque wrench with a deep socket, verify thatthe torque of the four mast clamp nuts is 20 foot–pounds(27.1 Newton–meters).Figure 4-17 Tightening the mast clamp nutshb0704 mast clamp nuts:20 foot-pounds(27.1 Newton-meters)2. Loosen each nut by one full rotation.(The mount stays in position, but will move when you turnthe azimuth adjuster with a wrench.)3. To determine the actual HT alignment direction with respectto your location on the roof, use the sector map you created(section 4.3), and protractor. Landmarks may also help.4. When the azimuth is properly adjusted, tighten the mast clamp nuts to 20 foot–pounds torque (27.1 Newton–meters).Fine azimuthadjustment
1027145–0001 Revision D Installing ODUs 4–23Hub installationTo adjust the antenna elevation (upward or downward pointingdirection), you rotate the antenna upward or downward, asillustrated in figure 4-18, until the elevation is set as desired.Antenna(front)Side view0elevation°DownwardelevationUpwardelevationT0006006Figure 4-18 Antenna elevation adjustment(upward or downward adjustment)Follow the steps below to adjust the antenna to the elevation anglespecified on the configuration document.First obtain a coarse elevation adjustment:1. Rotate the antenna until its elevation angle (angle fromhorizontal) is approximately the same as the specifiedelevation angle.This is a coarse elevation alignment—for now you canapproximate the antenna’s elevation angle by sight. Usually,the specified elevation is close to horizontal (near 0°).If the antenna does not rotate freely, loosen each of theantenna bracket nuts slightly.2. Finger tighten the reflector bracket locking nuts (again),so the antenna is snug and without excess movement.4.9Adjusting theantenna elevationCoarse elevationadjustment

1027145–0001 Revision D 4–30 Installing ODUs Hub installationGrounding the ODU requires several connections, as shown infigure 4-25. In making the ground connections, follow thesepractices:•For all ODU ground connections, use compressionconnectors (such as compression lugs or compressionclamps).•For all threaded ground connections, use a flat washer andlock washer (with the lock washer next to the nut).Ground the ODU as follows:1. Connect one end of the ground cable (No. 6 AWG orgreater, green) to the ODU ground connector, which isshown in figure 4-25.2. Connect the ground cable to a bolted joint on the mastmount.Important: For this connection, strip the cable but do notcut it. See figure 4-25. The cable continues from the boltedjoint to the ground point.3. Connect the ground cable to a suitable ground point on therooftop.The best ground point for the ODU is an earth–referencedroof ring conductor that follows the perimeter of thebuilding, constructed according to the requirements ofNFPA 780 or a similar regulatory code. However, such aconductor is not always present. Other alternatives areacceptable, as long as they comply with the groundingrequirements detailed in the Hub and Remote Terminal SitePreparation Guide.Building steel can also be used as a ground point. However,before using building steel, verify that the steel structureis electrically continuous throughout the entire buildingand that it is properly connected to earth ground. Fordetailed grounding requirements, see the Hub and RemoteTerminal Site Preparation Guide.4. Apply anti–oxidant (HNS 9008224–0002) to each groundlug (points 1, 2, and 3 in figure 4-25).5. Apply 1/2–inch (13–millimeter) heat shrink tubing (HNS9007488–0005) to each ground lug after the connection iscomplete.Important: You must slip the heat shrink onto the cablebefore you make the connections.Note: A resistance of less than 5 ohms is desirable from theODU to earth, including the earth field.4.11Grounding the ODU

1027145–0001 Revision D 5–4 Installing IFL cables Hub installationDetailed instructions for installing the IFL and lightning arrestorare included in the following sections.Determine the IFL cable route, from IDU to ODU. Consider theguidelines below. Every building and rooftop is unique; for thisreason, some of these guidelines may not apply to yourinstallation:•The most important considerations are the ODU and IDUlocations and the building entry point. The entry pointshould be as close as possible to the ODU. Refer to the HTrooftop drawings.•The maximum IFL cable length is 1000 feet (305 meters).•Where possible, use existing conduit.•You must use a pull box to facilitate pulling cables throughconduits if routing cable through bends totaling more than360°.•If existing conduits can not be used and the cable will beexposed, refer to building codes to determine proper cableinsulation type. For example, plenum rated cable must beused if cable will be run above suspended ceilings.•If you are installing the IFL cable(s) inside a conduitthat contains power cables, you must use plenum–ratedcable.•Look for cable routes that will be easily accessible, such asstacked telco closets etc.•Older buildings may not have stacked telco closets. Youmay have to route the cable back and forth, from one side ofthe building to the other.•Never run the IFL cable across corrugated roofing. Run thecable in the corrugation trough:hb009RoofYes NoCable5.3Determining the IFLcable route
1027145–0001 Revision D Installing IFL cables 5–5Hub installation1. Determine where the IFL cable will penetrate the roof.Refer to the HT rooftop drawings.Before you drill, consider these guidelines:•Important: Do not penetrate any part of the buildingstructure without first making sure you have the explicitpermission of the customer and building owner.•Horizontal penetration is preferable to vertical penetration.(A horizontal hole is less likely to leak.)•Take care not to destroy cabling or wiring under the roof orinside the wall.•Round penetration holes are preferred over square holes.(They are easier to make and seal.)2. Drill a 5–inch (127–millimeter) diameter hole at thebuilding penetration point.BuildingpenetrationpointBuilding surface5 inches(127 millimeters)hb0855.4Penetrating the roof
1027145–0001 Revision D 5–6 Installing IFL cables Hub installationThe IFL cable must be routed through a penetration sleeve beforeit is connected to the lightning arrestor. The lightning arrestor isattached to the penetration sleeve after cable installation.1. Use twelve screws to attach the hub penetration sleeve(sleeve and coupling) to the building surface at the buildingpenetration point. See figure 5-3.The type of screw used depends on the roof thickness andsurface composition. The screws must hold the sleeveassembly securely.Note: The penetration sleeve location is site–specific anddependent on the building penetration point. An optionalsweep, shown in figure 5-3, is available for use with thepenetration sleeve for locations where space is limited.Figure 5-3 Installing the hub penetration sleevert049Screws(12 total)BuildingpenetrationpointPenetration sleeve withoptional sweepSweep2.

1027145–0001 Revision D Installing IFL cables 5–7Hub installationYou install the IFL cable in two segments, as shown in figure 5-1(on page 5–3). To install the first cable segment—from the IDUchassis location to the lightning arrestor—follow the instructionsand guidelines below. Because every building has unique features,it is not possible to give exact instructions.1. Measure the cable run length from the IDU chassis locationto the lightning arrestor location (IFL building entry point).Allow for routing around obstacles and a service loop(excess cable, in case there is any reason to later cut andre–terminate the cable).2. Run the cable from the IDU chassis location, through anexisting conduit if possible, through the hub penetrationsleeve (figure 5-3), to the lightning arrestor location.Use a stand so the cable spool spins freely as it is pulled.Leave a service loop.CAUTIONAvoid making sharp bends in the IFL cable.The minimum bend radius for IFL cable is 2inches (51 millimeters). Sharper bends maycause permanent damage to the cable.3. Cut the cable at the IDU chassis location and at thelightning arrestor.Important: Cut the cable 2 feet (0.6 meters) beyond thelightning arrestor location (building penetration point).4. Terminate the cable end at the IDU chassis location with anN–type connector. For detailed instructions for connectingan N connector, see appendix C.Important: Sound IFL cable connections are critical forproper operation of the AIReach Broadband system.Therefore, be very careful in terminating the cable.

HUB INSTALLATION1027145–0001 Revision D Commissioning HTs 7–1Hub installation Chapter 7Commissioning HTsThis chapter includes:•Prerequisites for commissioning – page 7–2•HT commissioning procedure – page 7–3•HT to RT connection tests – page 7–8Commissioning refers to verification procedures to ensure that thenewly installed hub terminal (HT) is operational.Note: Most references in this chapter are to an HT. A hub mayconsist of one HT but usually consists of multiple HTs. EachHT—an ODU, IFL, and IDU—must be commissioned separately.
1027145–0001 Revision D 7–2 Commissioning HTs Hub installationTo ensure successful commissioning, you must verify that theprerequisites listed below have been accomplished. These tasksmust all be completed prior to commissioning. If any of them hasnot been done, make sure they are completed before you proceedwith commissioning.The HT ODU, IFL, and IDU must be installed andconnected.The Element Management System (EMS) hardware andsoftware must be installed and operational.All physical LAN connections between the HT and EMSmust be completed and operational.If the EMS is remote from the HT, the entire end–to–end linkmust be verified as operational. The EMS must be able toping the hub LAN router and the specific port to beconnected to the HT.The EMS database must be loaded and operational.The EMS operator has to enter the HT MAC address andconfigure the HT in the EMS database.(The HT MAC address is printed on a tag attached to theCCM and can also be read from the CCM LCD—from theMain Menu MAC display.)The CCM must be installed in the IDU. (SSIs are notrequired for commissioning.)Configure EMS and hub routers for EMS–hubcommunication.The hub router boot relay agent must be configured toforward boot requests from the HT to the EMS.If a backup HT has been installed, a CCM redundancy buscable must be connected.7.1Prerequisites forcommissioning
1027145–0001 Revision D Commissioning HTs 7–3Hub installationTo commission the HT, you apply power and observe the CCMLCD while the HT downloads software and configuration datafrom the EMS. This verifies that the HT equipment is operational.(However, the HT is not ready for service until SSIs have beenconfigured by the EMS operator.)To observe software and configuration downloading, you powerup the IDU and observe the LCD on the CCM front panel. TheCCM displays the following sequences:•Startup diagnostics (SUDS)•Boot up•Software loading•Configuration loadingAfter configuration loading, the LCD shows this message:HT Freq 1A1Disabled(Frequency is specific to HT)This display signals that downloading has completed, whichdemonstrates that the equipment is operational. The HT is disableduntil SSIs are installed and configured (through the EMS). When SSIs are installed and configured, the operational status isHT Enabled.7.2HT commissioningprocedureSummary
1027145–0001 Revision D 7–4 Commissioning HTs Hub installationStartup diagnostics (SUDS) begin when the CCM is first poweredup. SUDS test the CCM’s components individually1. Apply power to the IDU/ CCM, and observe the SUDSsequence on the LCD:For test identification details, see chapter 6, section 6.9.SUDS Timer TestSUDS WDT TestSUDS PCI TestSUDS SDPRAM TestSUDS Ser 1 TestSUDS Ser 2 TestSUDS LAN ID TestSUDS CPU Reg OKSUDS DRAM OKIf all diagnostics complete successfully, the SUDSsequence ends with a SUDS Completed message, asshown below. If a test fails, the specific test that fails isshown with a FAILED message, as shown below.SUDS Completed SUDS Ser 2 TestFAILEDorThe LCD remains inactive unless you power the CCM off,then on. This restarts SUDS.If any CCM component fails, replace the CCM.Startup diagnostics(SUDS) sequence
1027145–0001 Revision D Commissioning HTs 7–5Hub installationAfter successful completion of startup diagnostics, the CCMbegins the boot up sequence. A CCM restart (or softreboot—without loss of power) also initiates boot up.2. Observe the boot up sequence:Hardware InitializationInitializing The CCM hardwarecomponents are initialized.Several devices are initialized. If the baseband signalprocessor (BSP) is unable to initialize the device, thehardware is reset and another attempt to initialize occurs. Ifa device fails to initialize, it is reported on the second line ofthe LCD—for example:InitializingPLX FailedThe devices that are checked for initialization are listedbelow. In the event of failure, any of these devices couldappear on the second line of the LCD (with “Failed”).Device name on LCD DeviceHost Cfg Vrc4375 PCI controllerPLX PLX9050PLX IO PLX IO devicesLAN LAN controllerRCC FPGA RCC FPGABSB FPGA Baseband FPGAQPIG FPGA QPIG FPGATim Syn Timing synthesizerIf any CCM component fails, replace the CCM.Sending Boot RequestBoot Boot request is being sent toBOOTP server.If the CCM does not receive a Boot Reply message, theboot up sequence restarts (with hardware initialization). If,for example, the EMS is not operational (and therefore noBoot Reply message can be sent), the CCM will notprogress beyond the Boot display shown above.Boot up sequence
1027145–0001 Revision D 7–6 Commissioning HTs Hub installationWhen the CCM receives a boot reply message from the EMS bootserver, it begins to load its operational software.3. Observe the Loading Software message on the LCD:Loading SoftwareIf the CCM is unable to load its software, the LCD returnsto the boot up sequence.After loading its software, the CCM loads its configuration data.After loading its configuration, the CCM becomes operational.This is indicated by HT Disabled on the LCD.4. Watch for HT Disabled on the LCD: HT Freq 1A1Disabled(Frequency is specific to HT)This display signals that downloading has completed,which demonstrates that the equipment is operational.The HT is disabled, but operational, until SSIs are installedand configured (through the EMS). When SSIs are installedand configured, the HT is ready for service, and theoperational status is HT Enabled.The possible operational states are:Enabled HT is ready for service.Disabled Equipment is operational, but HTis not ready for service.Degraded One or more components is notfully operational.EnabledDegraded HT is ready for service, but oneor more components is not fullyoperational.Enabled In Test All of the HT’s SSI are in testmode.Software loadingConfiguration loadingOperational state
