SkyZhone 45 Installation Guide 192 DRAFTPREPARING FOR INSTALLATIONThis chapter explains how to prepare to install the SkyZhone 45 system, and includes the following sections:•Site selection requirements, page 19•Antenna path guidelines, page 19•Received Signal Level and link budget, page 20•Fade margin calculations, page 21•Unit Frequencies, page 21•Powering the units, page 21•Equipment, page 22Site selection requirementsThe performance of the SkyZhone 45 system depends upon its proper installation. A good installation conforms to these guidelines:•The antennas are installed in line-of-sight of each other, with adequate clearance.•The antennas are mounted to stable structures.•There is dependable, protected and easily accessible power at each site.•The coaxial connection between the IDU and ODU is no longer than 300 ft.Antenna path guidelinesThe SkyZhone 45 wireless transport will not operate properly unless you can see each antenna from the other. High frequencies used cannot pass through trees or other obstacles. In general, consider the following when calculating line-of-site between the antennas:•The curvature of the earth.•Buildings and trees.•Future tree growth and construction.

Preparing for Installation20 SkyZhone 45 Installation Guide DRAFTIn addition to line-of-sight clearance, a well-engineered high-frequency path will also incorporate additional clearance. Extra space is needed to compensate for signal loss due to partial obstructions, atmospheric inducting, and multipath reflections.To maximize radio reception•Calculate 0.6 times the first Fresnel zone•Add this distance to the path clearance above the tallest obstacle in the line-of-sight path.A typical Fresnel zone clearance required at mid-path over a 10 mile link is 28 feet at 6 GHz. An on-line resource for Fresnel zone calculations is available at:http://home.infi.net/~allenk/freszone.htmlReceived Signal Level and link budgetThe link budget is used to prevent signal reception problems. An Received Signal Level (RSL) is calculated and compared to the receive threshold of the SkyZhone 45SkyZhone 45 radio when the system is installed.Use the following formula to calculate the RSL:RSL (dBm) = Pout - FL1 + G1 + G2 - FL2 - Lpwhere:Pout is the transmitter output power (in dBm). See Table 14 on page 46 for values.FL1 is the feeder loss of the transmit side (in dB). This is typically -1 dB.G1 is the gain of the transmit antenna (in dB). Use the following values:•+29 dB for the 2 foot antenna •+33 dB for the 4 foot antenna•+37 dB for the 6 foot antenna.G2 is the gain of the receive antenna (in dB). Use the following values:•+29 dB for the 2 foot antenna•+33 dB for the 4 foot antenna•+37 dB for the 6 foot antennaFL2 is the feeder loss of the receive side (in dB). This is typically -1 dB.Lp is the Path loss defined by:Lp (dB) = 96.6 + 20 log10F + 20 log10D where: F= 5.8 (frequency in GHz)D=Distance of path in miles

Fade margin calculations SkyZhone 45 Installation Guide 21 DRAFTFade margin calculationsThe fade margin is the difference between the RSL and the receiver’s threshold. Use the RSL as calculated in “Received Signal Level and link budget”, and compare it to the receive threshold of the SkyZhone 45 radio (-88 dBm for BER of10-8) The fade margin is the difference between the two signal levels.A fade margin of at least 20 dB is suggested for reliable performance, and larger margins may be required over areas with water or thermal inversions.Unit FrequenciesThe SkyZhone 45 radios operate over two 100 MHz channels. The SkyZhone 45 system divides each 100 MHz wide band into seventeen overlapping sub-channels, each about 17 MHz wide. Spectrum reuse is maximized and signal interference is minimized by changing sub-channels, alternating polarization, and changing azimuth.Each system has an “A” and “B” ODU. The radio with ODU variant “A” transmits in the range of 5.725 to 5.825 GHz, and receives in the range 5.250 to 5.350 GHz. The “B” variant is the opposite, transmitting in the range 5.250 to 5.350 GHz and receiving at 5.725 to 5.825 GHz. This frequency split allows full duplex communications. Figure 6: SkyZhone 45 channel allocation For information about channel center frequencies, see “Channel center frequencies” on page 44. Powering the unitsThe SkyZhone 45 system ODU receives power from the IDU. The IDU must have access to a supply of appropriate power, either DC or AC. Do not connect both AC power and DC power to the same IDU.Power requirements are listed in Table 6 on page 16.

Do not place the product where the power cord could be walked on or damaged.

Antenna installation SkyZhone 45 Installation Guide 27 DRAFTAntenna installationWARNING! It is the responsibility of the installer to ensure that the antenna is mounted so that it is not accessible to the public and is not directed where dangerous levels of human exposure could result.Due to the possibility of exposure to Radio Frequency (RF) radiation above the recommended levels, do not stand within five (5) feet of the front of the antenna during system operation.Mechanical installationThe antennas are mounted to a vertical pipe or tower leg that has sufficient rigidity to prevent the antenna being moved by wind. Follow the wind load guidelines in the antenna installation instructions, and design the antenna structure with the wind load guidelines in mind.The antenna assemblies include mounting hardware that provides adjustment in vertical and horizontal planes.The antenna has a type-N style connector with a special sleeve to prevent its being connected except to the short coaxial cable that connects to the ODU.Three different-sized parabolic antennas are available with the SkyZhone 45. Parabolic antennas provide forward gain and protection from in-band interference on other azimuths. The FCC approval is valid ONLY when one of the Zhone Technologies, Inc. antennas are used. Do not use antennas from any other source. Read and use the installation instructions packaged with the antennas. Table 10 describes the instructions that apply to each antenna: Table 10: Antenna installation and adjustment proceduresAntenna version Description SSP2-52B (2 ft) Feed Assembly Plane Polarized Installation InstructionsAdjustable Parabolic Antenna Mount Installation InstructionsSSP4-52B (4 ft) 4’ and 6’ Diameter Microwave Antennas with Vertical Tilt Mount Installation InstructionsFeed Assembly Plan Polarized Installation InstructionsSSP6-52A (6 ft) 4’ and 6’ Diameter Microwave Antennas with Vertical Tilt Mount Installation InstructionsFeed Assembly Plan Polarized Installation InstructionsAll Antennas Weatherproofing the “Type N” Female Connector on Feeds

Installation28 SkyZhone 45 Installation Guide DRAFTAntenna alignmentEach antenna is aimed directly at, and has an optical line-of-sight radio path to, the antenna on the other end of the link. The presence of buildings, foliage or other obstructions within the radio path or the first Fresnel zone will impede performance and could prevent communications. Depending upon the antenna diameter used, the beam width of most of the transmitted signal will be 5 degrees or less, requiring that the antenna be accurately aimed. A quality magnetic compass and spirit level be should be used to aim the antenna. The azimuth of the other site must be known and magnetic deflection considered. You can consult topographical maps to determine the amount of local magnetic deflection.The antenna mounting hardware can be adjusted after the antenna is installed. To use the adjusting points, the clamping bolts must be slightly loose. After the antenna is aligned for maximum signal strength, tighten the mounting bolts.The antenna is connected to earth ground using #6 AWG copper ground wire, in compliance with local and national electrical codes.WARNING! There is no proven link between the low level of RF emitted by this device to any type of injury or disease, however, it is recommended that you follow these precautions to minimize unnecessary RF exposure:•Do not connect power to the IDU and do not install the cable between the IDU and ODU until the antenna and ODU are installed. This will prevent radiation from the antenna when people are within close proximity.•Do not install the antenna where it is possible for a person to stand within five feet of the radiating side.ODU installationThere are two versions of the ODU, labeled A and B. Each SkyZhone 45 system must have one A variant ODU and one B variant ODU. The A version transmits on frequencies between 5.725 and 5.825 GHz, and receives on frequencies between 5.250 and 5.350 GHz. The B version transmits on the lower frequencies and receives on the higher. Either variant can be used at either end of a link, however, it is recommended that the A variant be installed on the end of the link that is nearest the Central Office.

ODU installation SkyZhone 45 Installation Guide 29 DRAFTODU mechanical installationUse the mounting bracket that came with the ODU to install it. Use these guidelines to install the ODU:•The ODU must be installed within six feet of the antenna, or within reach of the 6 ft LMR-600 cable provided (see Figure 10 on page 32). This cable is very rigid and requires sufficient bending radius.•The mounting clamp is designed to secure the ODU to a pole or mast, and should be installed immediately below the antenna. •The ODU must be installed with its connectors pointing towards the ground. See Figure 10 on page 32 for an example of a properly installed ODU.To mount the ODU:1Install the mounting bracket to the pole or mast.2Install the side plates to the mounting bracket. (This ensures correct vertical spacing).3Open the ODU front cover and mount the unit to the side plates using the mounting screws. 4Secure the front cover of the weatherproof cabinet using the fastening tool provided with the system. Use of this tool prevents unauthorized access to the enclosure. See Figure 7 for a detailed view of installing the ODU mounting bracket to the pole or mast.

Installation30 SkyZhone 45 Installation Guide DRAFTFigure 7: ODU mounting installation detailYou can mount multiple ODUs to a single mounting bracket as shown in Figure 8.

ODU installation SkyZhone 45 Installation Guide 31 DRAFTFigure 8: Mounting optionsConnecting the ODU to the antennaThe ODU is has two coaxial connectors, as shown in Figure 9. The larger type N-style connector connects to the antenna, and the smaller TNC-style connector connects to the IDU.Note: The ground stud on the ODU must be connected to earth ground.Figure 9: ODU connector panelConnect the ODU to the antenna as shown in Figure 10.

Installation32 SkyZhone 45 Installation Guide DRAFTFigure 10: Connecting the ODU to the antennaSecuring the connectorsAfter connecting the coaxial cable to the antenna, secure the special N-style connector using an open-end adjustable wrench. Use care not to over-tighten the connectors. Caution: Make sure that the Type N connector to the antenna is properly and securely seated before you secure the connector cover. This connector cover can only be used once, because it strips the threads of the connector to prevent unauthorized or inadvertent removal. Once secured, the connector cover cannot be removed without damaging the antenna connector.Weatherproofing the type N connector After the coaxial cable is connected, wrap the Type N-style connector in butyl rubber sealant, and squeeze it firmly around all of the joints to make a continuous seal. For best weatherability, wrap the butyl seal with several layers of black PVC tape (not supplied).Adjusting azimuth and elevationThe antenna installation instructions explain azimuth and elevation panning. You can use these instructions, and a compass or GPS and a level, to roughly align the antenna. There will be a weak signal.RSSI test points inside the ODU provide a voltage that varies with receive signal strength. See Figure 11. The system must be provisioned and the link

IDU installation SkyZhone 45 Installation Guide 33 DRAFTmade operational before final azimuth and elevation adjustments can be made using the Received Signal Strength Indication (RSSI) test points.Figure 11: RSSI test pointsThe voltage range of the RSSI indication is very small, varying from 0.9 VDC to 1.4 VDC. Use a digital voltmeter capable of resolution at these ranges (for example, a Fluke model 77), and adjust the antenna’s azimuth and tilt until an optimal signal is reached as indicated by the voltage at the RSSI connection. A higher voltage indicates more signal strength. Use care not to “peak” the antenna on a side lobe, which is often about 20 dB below the main lobe in strength. The antenna should be on the approximate azimuth that was calculated using a compass and map.IDU installationThe IDU units are installed inside at each end of the microwave link, within 300 feet of the ODU, and are protected from rain or condensing moisture. Secure the IDU in the rack. Rack mount brackets are provided to install the unit into a 19- or 23-in rack as shown in Figure 12Caution: To prevent damage to the system, use only the screws provided.Note that all of the IDU connections are made on the rear panel. sz0101

SkyZhone 45 Installation Guide 394 DRAFTPROVISIONINGThis chapter explains how to provision the SkyZhone 45. It has the following sections:•Overview, page 39•The management interface, page 41•Provisioning overview, page 43•Verifying the installation, page 49•The QuickStatus command, page 50After the system is provisioned, it will be fully functional and able to transmit data.OverviewThe SkyZhone 45 system is provisioned through the DB-9 (Craft) serial port on the IDU using a VT-100 terminal or a PC running terminal emulation software. Note: The system will not transmit or receive until you complete the provisioning as explained in this chapter. This section gives a provisioning overview and includes these sections:•Provisioning the primary operational frequency, page 39•Provisioning the secondary frequency, page 40•Provisioning transmitter power, page 40•Provisioning the receive attenuator setting, page 40•Provisioning the transmit overlimit regulator, page 40•Enabling the RF power amplifier and LNA, page 40Provisioning the primary operational frequencyThe primary operational frequency is the frequency that the system will operate on when it is initiated. Before choosing this frequency, perform an interference analysis using a spectrum analyzer. The channel should be clear

Provisioning40 SkyZhone 45 Installation Guide DRAFTof interference for the specific azimuth and deployment. Seventeen overlapping channels are available for each of the A and B type systems. Provisioning the secondary frequencyThe secondary frequency is used as a backup if the primary channel become unusable due to interference. Before choosing this frequency, perform an interference analysis using a spectrum analyzer. The channel should be clear of interference for the specific azimuth and deployment. Choose one of the seventeen channels in the channel plan.Provisioning transmitter powerTransmitter power is regulated by controlling the value of an attenuator in the transmit portion of the ODU. There are 32 values from 00 (minimum) to 1F (maximum). Each HEX step changes the attenuation by 1 dB. The default system transmit attenuation is 15 dB.Provisioning the receive attenuator settingThe receive attenuator controls the signal level to the receiver input. Most systems operating over path lengths greater than one mile will require no extra attenuation in the receive path. Some installations, including those with large antennas, may require additional receive attenuation. There are 16 values from 00 (minimum) to 1F (maximum). Each HEX step changes the attenuation by 2 dB. The default receive attenuation is 0 dB.Provisioning the transmit overlimit regulatorThe SkyZhone 45 is equipped with a detector that monitors the actual transmit output level after the transmitter power amplifier. This enables the system to detect saturation of the power amplifier, which could cause the transmitter to exceed FCC maximum emission levels. If the ODU CPU detects the transmitter exceeding this level, the transmitter power amplifier will be shut down. There are three HEX settings for this detector that depend upon the antenna size. Enabling the RF power amplifier and LNAThis step in the provisioning initiates the RF transmission. The RF power amplifier and receive Low Noise Amplifier (LNA) are controlled by this command. Do not enable these amplifiers until the system is fully installed, the antennas are properly positioned, and there are no people in front of the radiating area of the antenna.

The management interface SkyZhone 45 Installation Guide 41 DRAFTThe management interfaceThe SkyZhone 45 IDU has an RS-232 serial (Craft) interface for managing the system. To access the serial port you must first configure your VT-100 terminal (or computer with terminal emulation software) with these settings:•9,600 bps•8 data bits•No parity•1 stop bit•Hardware flow control The IDU processes the configuration instructions and sends them to the ODU.The cable provided by the installer that connects the serial port on the PC or terminal to the RS-232 (Craft) port on the IDU must have continuity between the wires connecting pins 2, 3, 5, 7 and 8 between each connector. Do not use a null modem on this cable. The pin configurations for the IDU and ODU are shown in Table 12: Power-up indicationsWhen power is applied to the SkyZhone 45 system, there is an approximate 45 second wait, and then the following screen displays.Note: The VxWorks System version number, the bootrom version number and the Generic System Image version number are provided Table 12: RS-232 (Craft) port pin configurationPin Number Use1Not used2 Data to terminal3 Data from terminal4Not used5 Ground6Not used7RTS8CTS9 Ground

The following rules apply to the commands:•All of the commands are in uppercase letters.•The first character of the twelve character sequence command is always @. •The last two keystrokes are always an exclamation mark (!) and the Enter key, and look like this: ! <Enter>CommandsSetting the primary frequency This command sets one of the A01 through A17 or B01 through B17 channels as the primary frequency. A system with an A variant ODU will not accept a B channel assignment command, and a B variant ODU will not accept A variant channels.The default channel setting on factory shipped ODUs is channel 03. A variants will be shipped on A03. B variants will be shipped on B03.The following example sets the primary channel as A08:@ S F 0 P A 0 0 8 ! <Enter>The first three characters @ S F begins the command string for set frequency.The fourth character, 0, defines the unit number, which is always zero.The fifth character, P, indicates that the primary channel is being programmed.The sixth character, A, indicates a terminal with an A variant ODU is being provisioned.The seventh character, 0, is has no function.

Commands SkyZhone 45 Installation Guide 45 DRAFTSetting the transmit signal strengthTransmit power output level is controlled by the length of the IDU/ODU connecting cable and by the transmit attenuator setting. The length of the cable that connects the IDU and OCU must be considered when the power setting is selected.Table 14 is based on a 100 ft cable length. If the cable length is 50 ft, transmit power must be decreased by 3 dB. If the cable is 200 ft long, increase the transmit power by 3 dB. If it is 300 ft long, increase the transmit power by 6 dB.This command programs the transmit attenuator in the ODU. The HEX setting 00 is for full power and 1F is for full attenuation. This establishes the antenna output power. Table 14 shows the output in dBm and the resultant Effective Isotropic Radiated Power (EIRP) for all three antenna sizes. EIRP is calculated by substracting 1 dB loss in the antenna cable from the antenna gain. Caution: If a message displays “Not Allowed” then that attenuator setting cannot be used with the antenna. The installer is legally responsible for using an appropriate output power setting.

SkyZhone 45 Installation Guide 535 DRAFTSYSTEM MAINTENANCE This chapter describes basic system maintenance. It contains the following sections:•Physical maintenance, page 53•Diagnostics using the b byte, page 53•IDU LEDs, page 55Physical maintenanceThe SkyZhone 45 system does not require any regular maintenance but it is important that you monitor the radio link at regular intervals to make sure that the radio and all the link components are operating properly and that the link conditions have not changed.Because the antenna and ODU are exposed to the elements and are often in locations where others can access them, they should be inspected on a regular basis. Regularly check these things:•Antenna mounting hardware. This can be vibrated loose by the wind.•Cables. Connecting cables that are exposed on rooftops can be cut when walked on.•Cables that cross rooftops covered in crushed rock over tar can be cut by the sharp stones if someone walks on them. Diagnostics using the b byteAfter each full length command the system is given, the ODU answers with a response that contains the first character of the command. The second character is the b byte, which is a way to measure SkyZhone 45 system status. The response from the ODU looks like this example:> S b 0 0 0 0 0 xThe third character is the b byte. This HEX character displays information about the status of the ODU. The b byte should be 0 (zero) when the system is operating normally. The higher the HEX indication, the more severe the condition. The tenth character in this response is a check-sum digit, which may vary. The other digits in the response are not significant.
