If a user broadcasts information on the LAN, every other user on the LAN receives the broadcast. A router prevents broadcast messages from leaving a LAN, which reduces collisions and improves performance. A network manager can create smaller broadcast domains and reduce network broadcasts by logically segmenting a LAN into different broadcast domains. These broadcast domains are called Virtual Local Area Networks (VLANs). Workstations on a VLAN do not have to be located together because they are segmented logically, not physically. VLANs offer a number of advantages over traditional LANs including: • Performance • Security • formation of virtual workgroups • cost reduction All ports on a switch are configured for a default VLAN (usually VLAN1). When a switch receives data from a workstation, it tags the data with a VLAN identifier indicating the originating VLAN. The switch sends the data to the ports inside the VLAN where it originated. It also sends the data to a trunking port if one is available. Network Administrators create VLAN groups and place backbone network devices into the VLAN group to simplify administration and increase security of the devices. VLAN tagging allows network administrators to add AirPair nodes to the administrative network. VLAN tagging restricts administrative access to devices that are members of the VLAN group. If you program an AirPair node with an IP address but do not enable VLAN tagging, the node responds to Ping, Telnet and SNMP commands from any device on the network. Telnet and SNMP require a username and password, the proper IP address and community string, respectively. If you enable VLAN tagging, the AirPair nodes respond to ping commands but do not respond to Telnet and SNMP commands unless the packet has the correct VLAN tag. The Telnet and SNMP requests must have the correct VLAN tag and come from a device within the VLAN domain. The Institute of Electrical and Electronic Engineers (IEEE) is working on a draft standard 802.1Q for VLANs. Currently, most products are proprietary and anyone wanting to install VLANs has to purchase all products from the same vendor. DragonWave implements AirPair VLAN Tagging using the 802.1Q standard. For more information on the Standard, see the web page: http://grouper.ieee.org/groups/802/1/pages/802.1Q.html AirPair 100 UL 24 GHz Product Manual Description 33 Procedure 4-6 Setting VLAN Tag Note If you set the VLAN tag to the incorrect value, you can lose remote access to the AirPair.

Version 1.0 DragonWave Inc. 46 6.3. Fine-adjust alignment of the radios This section describes how to perform fine-adjust alignment of the radios. When you prepare to align the radios, you must consider two important factors: • Main Lobe and Side Lobes of Radio Waves • Clear Line of Sight (LOS) 6.3.1. Main Lobe and Side Lobes of Radio Waves When you align the radios, make sure you align to the Main Lobe of the transmission. If you mistake a Main Lobe for a Side Lobe during installation, there can be a 20-30 dB loss of signal strength. For example, if the Calculated RSSI = -42 dB then the side lobe would be at approximately -62 dB, or 20 dB lower than the calculated level. The size of the beamwidth for the 24 GHz AirPair systems is approximately 2 degree, which is approximately equivalent to a thumb's width when the arm is fully extended. Align as closely to the centre of the 2-degree beamwidth as possible. It takes very little adjustment to swing past the main lobe, as can be seen in Figure 6-7. A beamwidth of 2 degrees is narrow and alignment errors can occur when you lock on to a Side Lobe instead of onto the Main lobe. If you align to a Side Lobe and miss the Main Lobe, your signal strength is reduced. Make sure you align the antenna to the Main Lobe. Note: Verify the RSSI is within 2 dB of the calculated value. Figure 6-7 2 Degree Beamwidth AirPair 100 UL 24 GHz Product Manual Installation of Radio and Antenna 47 Figure 6-8 Main and Side Lobes - Radio Signal Using 12″/30 cm Antenna Version 1.0 DragonWave Inc. 48 6.4. Clear Line of Sight Caution There can be no obstructions in the Fresnel zone. If there are obstructions within this broad beam or Fresnel Zone, some of the signal is diffracted off the obstruction, with an accompanying phase shift. The AirPair must have a clear line of sight. Use caution and make sure there is proper Fresnel Zone clearance. The size of the beam grows as it propagates towards the destination. The beam must have no obstructions in its path. Obstructions within the path of the beam can decrease the signal quality by diffracting the signal. When you consider Fresnel Zone clearance, you must consider both the height above and the lateral distance from obstructions Figure 6-9 show trees within the Fresnel zone that obstruct the signal. Do not allow any obstruction of the Fresnel Zone. AirPair 100 UL 24 GHz Product Manual Installation of Radio and Antenna 49 Figure 6-9 WRONG! Obstruction of the Fresnel Zone Figure 6-10 WRONG! Trees within the Fresnel Zone Obstruct the Signal Fresnel Zone Version 1.0 DragonWave Inc. 50 6.5. Fine-adjust align the radios Caution Alignment of the radios requires power to be supplied to the modem. Caution Proper alignment results in increased signal quality! Once the radios have been visually aligned, fine adjust alignment can begin. Pan across the entire beamwidth to ensure the alignment corresponds to the Main Lobe and not to a Side Lobe. Caution Transmission of radio signals results in a primary signal (Main Lobe) and secondary signals (Side Lobes) being sent towards the destination. During installation the Side Lobes can be mistaken for the Main Lobe, resulting in a 20-30 dB loss of signal strength. On a 12”/30 cm antenna, the entire beamwidth typically lies within a 5 degree span so it is critical to ensure alignment targets the Main Lobe and not the Side Lobes. Larger antennas have a narrower beam. For a 24”/60 cm antenna, the entire beamwidth lies within a 3 degree span. Note: It is recommended that you use the DragonWave’s DragonPair PDA software when aligning 24 GHz AirPair systems. DragonWave’s software runs on a Personal Digital Assistant (PDA) with Palm OS V3.1 or higher. The software provides an Antenna Alignment Indicator that shows relative signal strength. It retains the peak value that was reached. This allows for multiple panning attempts. AirPair 100 UL 24 GHz Product Manual Installation of Radio and Antenna 51 Figure 6-11 Modem Procedure 6-6 Fine-adjust Align Radios Use this procedure to fine-adjust the alignment of the radios. At the first end: (a) Pan or move the antenna horizontally at one end across the entire beamwidth to identify the Main Lobe and the two side lobes. See Figure 6-8. Place a mark on the radio bracket to identify Main Lobe and each of the Side Lobes. The Main Lobe is approximately 2 degrees in width. The two Side Lobes are approximately 5 degrees apart. (b) Tilt or move the antenna vertically and locate the strongest receive signal reading. (c) Pan or move the antenna horizontally and locate the strongest receive signal reading. (d) Tighten the bolt to lock the antenna in place. At the other end: (a) Pan or move the antenna horizontally at one end across the entire beamwidth to identify the Main Lobe and the two side lobes. (b) Tilt or move the antenna vertically and locate the strongest receive signal reading. (c) Pan or move the antenna horizontally and locate the strongest receive signal reading. Version 1.0 DragonWave Inc. 52 (d) Tighten the bolt to lock the antenna in place. At the first end: (a) Pan or move the antenna horizontally at one end across the entire beamwidth to identify the Main Lobe and the two side lobes. (b) Tilt or move the antenna vertically and locate the strongest receive signal reading. (c) Pan or move the antenna horizontally and locate the strongest receive signal reading. (d) Tighten the bolt to lock the antenna in place. (e) Repeat these steps as necessary to obtain maximum signal strength. Notes: 1. While Horizontal Alignment is being performed, ensure the Vertical Alignment lockdown bolts are securely tightened to prevent movement, and vice versa for Vertical Alignment. 2. The RSSI level should be within 2 dB of predicted levels. Factors that contribute to low RSSI levels are: • incorrect antenna alignment - aligned to side lobe and not main lobe; • improper polarization of antennas - horizontal vs. vertical. • path issues • obstructions such as trees, hills, or buildings within the beamwidth • path clearance issues such as diffraction, partial obstruction, earth curvature 3. Ensure alignment corresponds to the Main Signal Lobe and not to the Side Lobes. 4. The connectors (Power cable, IF cable, Serial cable, and Ethernet cable) on the AirPair units are of a weatherproof design. Sealing of connectors is not necessary. 5. Once the radios and modems have been installed and aligned, you need to ensure that the grounding cables at the radio and modem are properly sealed using potting compound, rubberized tape or other waterproof material. Cable corrosion can result in decreased quality of grounding connections, and therefore present greater risk of personal or equipment damage during lightning strikes. AirPair 100 UL 24 GHz Product Manual Installation of Radio and Antenna 53 6.5.1. Perform a Data Test This section describes how to perform a data test. Procedure 6-7 Perform a data test Perform this procedure to confirm the network link is working properly. It is assumed that you are using an Ethernet traffic-generating device. 1. Connect the device to the Ethernet cable at either end. 2. Confirm data can be passed within desired error rates. This will ensure the network link is working in a satisfactory manner prior to running applications over the link. 6.5.2. Connect to the LAN This section describes how to connect the system to the LAN with an Ethernet cable. Caution The Ethernet Cable is meant to be connected to a Server and therefore the signal pairs on the cable must be switched in order to connect to a router or a switch. Once alignment, sealing of cables and data test have been completed, connect the Ethernet cable to your network device. Ensure optimum throughput. The Ethernet connection to the modem is intended to operate at 100 Mbps Full Duplex for AirPair 100 and at 50 Mbps Full Duplex for AirPair 50. Version 1.0 DragonWave Inc.

For example, you can set the sysContact in MIB -II (RFC 1213) using your MIB browser, e.g., HP OpenView Node Manager. save mib Saves the MIB to FLASH. Perform this command save setting changes to FLASH. This command does not restart the system and does not put any new settings into effect. Sequence: save mib press Enter The system responds: Mib saved successfully. AirPair 100 UL 24 GHz Product Manual Setting Up SNMP 57 7.1.1. AirPair Enterprise Management Information Base A Management Information Base (MIB) contains information about a network device that is managed by SNMP. AirPair supports industry standards MIB I and MIB II. In addition, DragonWave provides an enterprise MIB for AirPair. For a list of objects and their definitions refer to the AirPair MIB definition file on the DragonWave Toolkit CD-ROM. You must load the AirPair MIB onto your own MIB browser or Network Management Station (NMS). HP OpenView is an example of network management software to be used on the NMS. The AirPair Enterprise MIB is provided in a standard MIB format that allows a more direct method of loading the definitions onto the NMS. On some NMS systems, it is as straight-forward as placing the AirPair MIB into the proper NMS directory and then enabling it by adding it to the MIB list. Please consult the instructions provided with your NMS for details on loading the Enterprise MIBs. 7.1.2. Traps A trap is a message that reports a problem or a significant event. Traps are defined in AirPair MIB definition file. For a complete list of traps, refer to the MIB definition file on the AirPair Toolkit CD-ROM. Procedure 7-2 Enable traps Perform this procedure to enable traps. Required Action Steps telnet Telnet to the AirPair. Note: You may also connect using a serial cable. get snmp trap hosts Displays a list of receivers of SNMP traps.

AirPair 100 UL 24 GHz Product Manual 64 Appendix A – Frequency Channel Plans This appendix describes frequency channel plans. Table A- 1 lists the FCC Channel Plans for 24 GHz. Note: Either of the two radios may be programmed at the GO frequency. The other radio must then be programmed at the matching RETURN frequency for coupled (paired) operation. Therefore, using the table below, if one radio is set to transmit at 24080 MHz, then other radio must be set to transmit at 24150 MHz. Refer to the section below for decoupled (unpaired) operation. Table A- 1 Available Standard Frequencies GO RETURN Frequency (MHz) Frequency (MHz) 24080 24150 24090 24160 24100 24170 24110 24180 24120 24190 24130 24200 24140 24210 24150 24220 Should many 24 GHz systems be deployed in the same small geographical footprint, then DragonWave’s 24 GHz system allows full control of the frequencies. Normally, the frequencies are paired according to the table above, however unpaired frequency operation is allowed. Note the frequencies must differ by a minimum of 70 MHz. For example, if one radio is set to a frequency of 24080 MHz, then the other radio must be set to a minimum offset of 70 MHZ and therefore must be set to 24150 MHz or higher. There are no other restrictions on frequency selection that is to say that any frequency combinations may be selected as long as the spacing is a minimum of 70 MHz. Therefore, if one radio is set to 24150 MHz then the other radio may be set to a frequency of 70 MHz higher (24220 MHz), or 70 MHz lower (24080 MHz).
