Chapter 3 Hardware Installation This chapter sets out the requirements and procedures for the hardware installation and alignment of a RADWIN 1000/2000 link in accordance with the prior planning as set out in chapter 2. It is intended to guide qualified field technicians. Warning Outdoor units and antennas should be installed ONLY by experienced installation professionals who are familiar with local building and safety codes and, wherever applicable, are licensed by the appropriate government regulatory authorities. Failure to do so may expose the end user or the service provider to legal and financial liabilities. RADWIN and its resellers or distributors are not liable for injury, damage or violation of regulations associated with the installation of outdoor units or antennas. Safety Practices Preventing overexposure to RF energy To protect against overexposure to RF energy, install the ODUs so as to provide and maintain minimal separation distances from all persons. When the system is operational, avoid standing directly in front of the antenna. Strong RF fields are present when the transmitter is on. The ODU must not be deployed in a location where it is possible for people to stand or walk inadvertently in front of the antenna. Grounding All RADWIN products should be grounded during operation. In addition: • The ODU should be earthed by a wire with diameter of at least 12AWG. The RADWIN 1000/2000 ODU must be properly grounded to protect against lightning. It is the user's responsibility to install the equipment in accordance with Section 810 of the National Electric Code, ANSI/NFPA No.70-1984 or Section 54 of the Canadian Electrical Code. These codes describe correct installation procedures for grounding the outdoor unit, mast, lead-in wire and discharge unit. It RADWIN 1000/2000 User Manual Version 2.2a 3-1 Protection against Lightning Chapter 3 also lays down the size of grounding conductors and connection requirements for grounding electrodes. The RADWIN 1000/2000 ODU must be grounded to a Protective Earth as described in appendix E and in accordance with the Local Electrical Regulations. • The earth lug on the IDU-C should be connected to the protective earth at all times, by a wire with a diameter of 18 AWG or wider. Rack-mounted equipment should be mounted only in earthed racks and cabinets. Further, you should • Always make the ground connection first and disconnect it last • Never connect telecommunication cables to ungrounded equipment • Ensure that all other cables are disconnected before disconnecting the ground More detailed guidelines are supplied in appendix E. Protection against Lightning The use of lightning protection is dependent on regulatory and end user requirements. All of RADWIN outdoor units are designed with surge limiting circuits to minimize the risk of damage due to lightning strikes. RADWIN recommends the use of additional surge arrestor devices to protect the equipment from nearby lightning strikes. See appendix E for detailed installation instructions of lightning protection devices. General • It is recommended that installation of the outdoor unit be contracted to a professional installer. • Before working on equipment connected to power lines or telecommunication lines, you should remove jewelry or any other metallic object that may come into contact with energized parts. • Use extreme care when installing antennas near power lines. • Use extreme care when working at heights. • When using an AC power source for RADWIN 1000/2000 always use the AC power adapter supplied by RADWIN. • Use the right tools. In addition to standard tools required for any kind of ODU or antenna installation, RADWIN 1000/2000 requires additional specific tools detailed on page 3-5 below.

Outdoor installation Mounting the ODU The ODU can be mounted on a pole or a wall. In both installations, the supplied mounting kit is used to secure the ODU. A mast-sited ODU typically uses a pole attached to the mast. Note A RADWIN 1000/2000 link operates in pairs of two ODUs with the same configuration. Both ODUs must be installed, and the antennas aligned for maximum throughput. RADWIN 1000/2000 User Manual Version 2.2a 3-6 Mounting external antennas Warning Chapter 3 Prior to connecting cables to the ODU, the protective earth terminal (screw) of the ODU must be connected to an external protective ground conductor or to a grounded pole. • Only a qualified person using the proper safety equipment should climb the antenna mast • Only qualified professional personnel should install or dismantle ODUs and masts ¾ To mount the ODU on a pole or a wall: 1. Ensure that the ODU is properly grounded. 2. Mount the ODU onto the pole or wall. Ensure that the unit is oriented so that the cable connectors are at the bottom. (If they are on top, water may penetrate into the unit causing damage.) 3. Refer to Appendix C, Pole and Wall Installation for detailed ODU mounting kit contents and schematics. Do not tighten the ODU to its mounting brackets until the alignment process of the antenna is complete. Note Ensure that there are no direct obstructions in front of the ODU or interference from man-made obstacles. Mounting external antennas If you are using ODU with an integrated antenna, skip to Mounting the Lightning Protection Devices below. The supplied mounting kit is used to mount the antenna onto a pole. The antennas must be aligned for maximum throughput. Do not stand in front of a live antenna. Warning ¾ To mount an external antenna: 1. To mount an external antenna ensure that the antenna is properly grounded and then mount the antenna onto the pole. Refer to Appendix C, Pole and Wall Installation for detailed antenna mounting instructions. 2. Follow the mounting instructions supplied with the antenna. Mounting the Lightning Protection Devices The use of lightning protection is dependent on regulatory and end user requirements. The RADWIN 1000/2000 ODU is designed with surge limiting circuits to minimize the risk of damage due to lightning strikes. RADWIN RADWIN 1000/2000 User Manual Version 2.2a 3-7 Outdoor Connections Chapter 3 recommends the use of additional surge arrestor devices to protect the equipment from nearby lightning strikes. Refer to appendix E for detailed installation instructions of lightning protection devices. Outdoor Connections ¾ To complete the outdoor connections: 1. Connect the ground cable to the ODU chassis as marked on the ODU. 2. Connect the antenna cable(s) to the ODU. 3. Connect the lightning protection device to the ODU (see appendix E). 4. Attach the ODU-IDU cable to the ODU RJ-45 connector (see appendix B for the connector pin-out) 5. Screw in the cable glands to ensure hermetic sealing of the ODU. 6. Secure the cables to the pole, mast or brackets using UV-rated cable ties. Indoor Installation Mounting the IDUs The RADWIN 1000/2000 IDUs are all rack mounted, as shown in figure 16. A front panel keyed schematic of a rack mounted IDU-C is shown in figure 3-7 below. Figure 3-7: IDU-C front panel In figure 3-8 we display a perspective view of the IDU-C: RADWIN 1000/2000 User Manual Version 2.2a 3-8 Mounting the IDUs Chapter 3 Figure 3-8: IDU-C - A perspective view Further description of the keyed items in figure 3-7 is shown in table 3-1 below: Table 3-1: Components of an IDU-C front panel Key Label Remarks Indicator LEDs See figure 3-9.

If the rack already holds other equipment, ensure that it is properly grounded. Do not proceed with installation into a “live” rack unless it is properly grounded. Warning 2. Attach the rack mounting brackets (K) to the IDU. 3. Bolt the IDU into an empty slot in the rack, ensuring that it sits securely. 4. Ground the IDU to the rack using grounding lug I. The IDU should be left permanently grounded. Instead of using the rack mounting brackets, the IDU may be rail mounted using the four screw holes on each of its sides. Note RADWIN 1000/2000 User Manual Version 2.2a 3-10 Connecting power to the IDU Chapter 3 Connecting power to the IDU The IDU-C has redundant power connection circuits (items G and H in figure 3-7 above). An enlarged schematic of the power connectors is shown in below: Figure 3-10: DU-C ower connectors The connectors are 3 pin in line female, with polarities (left to right) minus, ground, plus. To avoid damage to the IDU, always use an AC/DC adapter supplied by RADWIN. Ensure that the IDUs at both sites are powered up. Connecting the ODU to the IDU The ODU-IDU cable conducts all the user traffic between the IDU and the ODU, and also provides power to the ODU. The maximum length of the ODU-IDU cable is 100m (328 ') in accordance with 10/100BaseT standards. The ODU-IDU cable is supplied pre-assembled with RJ-45 connectors, at the length specified when ordering, or as a cable drum with spare connectors. If the ODU-IDU cable was not ordered, use an outdoor class, CAT-5e 24AWG shielded cable. See appendix B for Wiring Specifications. To connect the ODU to the IDU, route the cable from the ODU to the IDU, secure the cable along its path and connect the cable to the ODU RJ-45 connector on the IDU (see item B in figure 3-7 above). Installing a Link using PoE Devices The PoE device is a very simple unit having a power input connector and two Ethernet ports. It is AC powered, and has a power LED. ¾ To prepare a link using PoE devices: 1. To connect the ODU to the PoE device, route the cable from the ODU to the PoE device, secure the cable along its path and connect the cable to the P-LAN-OUT RJ-45 connector on the PoE device. 2. Connect it to AC power. 3. Repeat steps 1 to 2 for the second link. RADWIN 1000/2000 User Manual Version 2.2a 3-11 Connecting User Equipment Chapter 3 Connecting User Equipment ¾ To connect user equipment to the IDU: • Connect user switch/router or any other compatible device to the IDU panel RJ-45 ports designated LAN (see item C in figure 3-7 above). Refer to appendix B, Wiring Specifications, for connector pinouts. Do not connect two LAN ports to the same network, or flooding may occur. Note ¾ To connect user equipment to the PoE device: • Connect a user switch, router or any other compatible device to the PoE device RJ-45 port designated LAN-IN. Refer to appendix B, Wiring Specifications, for connector pinouts. Connecting and Aligning ODUs / Antennas You perform antenna alignment using the ODU's audible tone. To speed up the installation time, alignment of a RADWIN 1000/2000 system should be performed by two teams simultaneously, at site A and at site B. ¾ To align ODUs with integrated antennas or external bipolar antennas: 1. For external bipolar antennas: Using a coax cable with N-Type connectors, connect the vertical polarization connector of the antenna to the ANT 1 connector of the ODU. 2. For external bipolar antennas: Using a coax cable with N-Type connectors, connect the horizontal polarization connector of the antenna to the ANT 2 connector of the ODU. 3. Ensure that power is connected to the IDUs at both sites. 4. Ensure normal operation of the IDUs by the LED indications on the front panel. Provided that site A detects the signal from site B, the ODU starts beeping 20 seconds after power up, and continues beeping until the ODUs are aligned, and the installation is complete. In the following steps, “antenna” refers both to an external antenna and an integrated antenna. 5. Direct the antenna of site B in the direction of site A. This is simplified if a previous site survey has been completed and azimuths are known. When aligning the antennas, do not stand in front of a live antenna. Warning RADWIN 1000/2000 User Manual Version 2.2a 3-12 Connecting and Aligning ODUs / Antennas Chapter 3 6. Make a horizontal sweep of 180 degrees with the site A antenna so that the strongest signal from site B can be detected. 7. Slowly turn the site A antenna back towards the position of site B, listening to the tone until the best signal is reached. See the following figure for audible signal variations. Figure 3-11: Beep Sequence for antenna alignment Note • Three beeps and a pause is 'best signal so far' • Two beeps and a pause is 'signal quality increased' • One beep and pause is 'no change in signal' • Long beep and short pause is 'signal quality decreased' • One beep and a long pause is 'no air link' • Any other signal does not relate to antenna alignment 8. Secure the site A antenna to the pole/wall. 9. Repeat steps 4 to 8 for site B. ¾ To align two external monopolar antennas: The ODU buzzer only works on the radio connected to the ANT 1 connector marked Note . You will therefore need to use ANT 1 to align both antennas in turn. Upon completion of the alignment procedure, you may connect the two antennas to ANT 1 and ANT 2 connectors. 1. Using a coax cable with N-Type connectors, connect one antenna to the ANT 1 connector of the ODU. 2. Follow the steps 3 to 7 above to align the antenna connected to the ODU connector ANT 1 on both sides of the link. 3. On both sides of the link, disconnect the antenna connected to the ODU connector ANT 1. Connect the other antenna to connector ANT 1 and follow the steps 3 to 7 above to align the second antenna. 4. Secure the antennas to the pole/wall. 5. Restore one of the antennas to ANT 2 on both sides of the link.

The procedure required to make the link functional has three phases: 1. Link Installation - which we will detail below. Installation actually gets the link operational by setting the link parameters. It uses a fixed channel at the lowest possible modulation, BPSK at 6.5Mbps and will work under the harsh interference condition. During the installation procedure, the definition of all parameters is automatically applied to both sides of the link. Note 2. Link Configuration - described in chapter 5. Configuration provides much the same functionality as Installation, but for a running link. A fallback to Installation mode is provided for situations which cannot be handled without resetting the link, such as antenna realignment and IDU or ODU replacement. The Link Installation and Configuration phases are both carried out with Wizards, which “walk you through” the processes. The Wizards are visually quite similar and will be described in detail below. RADWIN 1000/2000 User Manual Version 2.2a 4-8 Default Settings Chapter 4 3. Site Configuration - described in chapter 6. Site specific configuration for each side of the link is available at any time - under a running link or under the restricted Installation mode. Site Configuration consists of a set of panels, which may be invoked individually in any order, as needed. An installed and configured link can be returned to installation mode for reinstallation and configuration from last settings or from factory settings. Note • Reversion to installation mode requires a complete break in the link service • Configuration mode may vary the service throughput and quality, but without a service break Default Settings The default settings of the RADWIN 1000/2000 configuration parameters are listed in table 4-3 below: Table 4-3: Default Settings Parameter Default Value ODU IP Address 10.0.0.120 Subnet Mask 255.0.0.0 Trap destination 0.0.0.0 Manager Login password admin Link ID Link Site 1 Site Site 2 Site Link Password wireless-bridge Rate Adaptive Ethernet Configuration Auto Detect Radio Link Failure Actions No action Bridge or Hub mode Hub Mode, Aging time = 300 sec Community values Read-write – netman Read-only – public Front Panel LEDs on the IDU-C The front panel LEDs on the IDU provide basic information about link status.

Installing the Link: Step 4, Tx Power and Antenna Settings The Tx Power and Antenna Parameters dialog appears. RADWIN 1000/2000 User Manual Version 2.2a 4-19 General Chapter 4 Figure 4-15: Transmission Power and Antenna Parameters The choice of Tx power, antenna gain and cable loss determines the EIRP and is affected by such considerations as radio limitations and regulatory restrictions. Before proceeding to antenna installation details, the following background information should be considered: General Each RADWIN 1000/2000 ODU is made of two radio transceivers (radios). The radios make use of algorithms that utilize both polarization and space diversity resulting in enhanced capacity, range and link availability. The number of antennas (i.e. radios) used is determined by user configuration and by automatic system decisions, explained below. Dual Antennas at Both Sites Using dual antennas at both sites (single bipolar antenna or two monopolar antennas) enables the use of MIMO technology. With MIMO the system doubles the link capacity. At the same time, it keeps the same rate and modulation per radio as was used with single antenna, thus increasing capacity, range and availability. RADWIN 1000/2000 User Manual Version 2.2a 4-20 Single Antennas at Both Sites Chapter 4 For example with a dual antenna RADWIN 1000/2000 can transmit at modulation of 64QAM and FEC of 0.83 and get an air rate of 130 Mbps, compared to 65 Mbps with single antenna. To work in this mode, each antenna port must be connected to an antenna, the RSS level in both receivers should be balanced and a minimal separation between the antennas must be maintained. (For example, by using dual polarization antennas a cross polarization separation is attained). Upon selecting Antenna Type as Dual, RADWIN 1000/2000 automatically doubles the air rates. RADWIN Manager indicates a case of unbalanced RSS between the two antennas. Single Antennas at Both Sites By selecting a single antenna at both sites the ODUs operate with a single radio that is connected to the ANT 1 connector. The second radio is automatically shut down. Single and Dual Antennas In this mode one of the sites uses the ODU with a single antenna while the other site uses the ODU with a dual antenna. The advantages in this mode in comparison to using a single antenna in both sites are doubled total Tx power and additional polarization and/or space diversity. RADWIN 1000/2000 automatically switches to this mode if one of the ODUs is connected to a dual antenna or if the RSS at one of the ODU receivers is below minimal level. The air rates used in this mode are same as when using single antennas in both sites. RADWIN 1000/2000 User Manual Version 2.2a 4-21 Considerations for Changing Antenna Parameters Chapter 4 The rates used by RADWIN 1000/2000 are shown in Table 4-5 below: Table 4-8: RADWIN 1000/2000 Transmission rates Radio Modulation FEC Air-Rate [Mbps] Single BPSK 1/2 6.5 Single QPSK 1/2 13 Single QPSK 3/4 19.5 Single 16QAM 1/2 26 Single 16QAM 3/4 39 Single 64QAM 2/3 52 Single 64QAM 3/4 58.5 Single 64QAM 5/6 65 Dual BPSK 1/2 13 Dual QPSK 1/2 26 Dual QPSK 3/4 39 Dual 16QAM 1/2 52 Dual 16QAM 3/4 78 Dual 64QAM 2/3 104 Dual 64QAM 3/4 117 Dual 64QAM 5/6 130 Considerations for Changing Antenna Parameters Let: maxAllowedTx Power denote the maximum Tx Power practically available from an ODU. It appears as Tx Power per Radio in figure 4-16 below. maxRegEIRP denote the maximum EIRP available by regulation. It will be determined by three factors: • per band/regulation • per channel bandwidth • antenna gain It appears in figure 4-16 as Max EIRP. maxRegTxPower denote the maximum regulatory Tx Power for the equipment, also having regard the above three points RADWIN 1000/2000 User Manual Version 2.2a 4-22 Considerations for Changing Antenna Parameters Chapter 4 maxODUTxPower denote the maximum Tx Power of the ODU, itself depending on the air rate used. Then, the following relationship must be satisfied: maxAllowedTxPower ≤ min(maxRegEIRP – AntennaGain + CableLoss, maxRegTxPower) ... (*) These parameters are controlled as follows: ¾ To set Tx power and configure antennas: 1. Click the Configure buttons in turn to configure the antennas on both sides of the link. Each one offers a dialog like this: Figure 4-16: Antenna configuration dialog with opened type selection 2. Choose the antenna type and required transmission (Tx) power for the first site and click OK. Repeat the process for the second site. The Tx power (per radio) indicates the power of each radio inside the ODU and is used for Link Budget Calculations. The Tx power (System) shows the total transmission power of the ODU and is used to calculate the EIRP according to regulations. To see the relationship between Tx Power (radio) and TX Power (system), note that dBm = 10 × log 10milliWatt so that if you double the power in Note milliWatts (for two radios) then dBm will increase by 10 × log 102 ≈ 3 . RADWIN 1000/2000 User Manual Version 2.2a 4-23 Considerations for Changing Antenna Parameters Chapter 4 3. Set the Antenna Gain and Cable Loss. If do this you will receive a warning message: Figure 4-17: Antenna parameters change warning Note • The Max EIRP level will be automatically set according to the selected band and regulation. • The EIRP level is the sum of the System Tx power and the Antenna Gain minus the Cable Loss. If inequality (*) above is violated, then the following warning window is displayed: Figure 4-18: Tx Power Limits The precise relationship between the items in inequality (*) and the window of figure 4-16 is follows: RADWIN 1000/2000 User Manual Version 2.2a 4-24 Installing the Link: Step 5, Services Chapter 4 • Required Tx Power (per radio) will be adjusted down to the lesser of the value entered and maxAllowedTxPower • TxPower (system)is maxAllowedTxPower + 3 (for 2 radios) • Max EIRP is maxRegEIRP. • EIRP is maxAllowedTx Power + Antenna Gain - Cable Loss The table in figure 4-18 only shows rates where the maximum Tx Power is the limitation, rather than regulations. Recall that maxAllowedPower and maxEIRP are regulatory. In an unregulated environment, the only limit is maxODUTxPower. Note When you close the window of figure 4-18, the change you requested will not be honored, and you will need to try again. 4. When you are finished with Tx Power configuration, Click Next.
