3CHAPTERobr3650_ml_01_sd Approved: C.W. 3-13.0 Getting Started with OBR36503.1 Before You BeginThe OBR3650 provides the base station component of the Vecima VistaMAX system. To set up and configure the base station, you require the following:• One VistaMAX OBR3650 base station with a stand-alone Power over Ethernet (PoE) or WES800 Ethernet Switch• One VistaMAX outdoor subscriber station or indoor subscriber station such as the OSR3500C or ISR3510.• One of the following components to provide the DHCP and TFTP server:– Vecima’s Network Management 8000– A third-party DHCP and TFTP server as per the WiMAX standard. This setup is not covered in this manual.Setting up the system using NMS8000Using the NMS8000 as the provisioning tool for all OSR subscriber stations and hosts on the VistaMAX system is the most common scenario. The platinum, gold, silver, or bronze VistaMAX starter kits available from Vecima Networks includes an NMS8000.NOTEIf you wish to connect Internet-accessible hosts to the VistaMAX system, you will need to provide a router witha public IP address and a valid DNS server. When you are connecting to Internet-accessible host and using theNMS8000, Vecima recommends connecting one of the NMS8000 Ethernet interfaces on a public routeable IPaddress.Figure 3-1 Using NMS8000 to Provision VistaMAX System
obr3650_ml_01_sdApproved: C.W.3-23.2 Overview of ConfigurationThe following steps outline the process for configuring a VistaMAX system. This process assumes that you are using an NMS8000.Step 1 Use CAT5 straight-through Ethernet cables to connect the physical components as shown in Using NMS8000 to Provision VistaMAX System.Step 2 Use the Web-based interface to configure the IP addresses for the base station and subscriber station(s).If necessary, configure the IP addresses for the NMS8000.Step 3 Use the Web-based interface to configure the radio parameters for the base station and subscriberstation(s).Step 4 If necessary, use the Web-based interface for the NMS8000 to add the subscriber stations on theNMS8000.Step 5 Establish the link between the base stations and subscriber stations and verify that the subscriber stationsare online.The steps that pertain to the base station are described in more detail below. For more information, refer to the NMS8000 & NMS8000/SSP Network Management Server Installation and Operation Guide or related information listed under Finding Related Documentation on page iii.
obr3650_ml_01_sd Approved: C.W. 3-33.3 Using the Web Based InterfaceThe Web interface of the OBR3650 system may be viewed with a standard web browser such as Mozilla™ or Internet Explorer™, no additional add-ins are required.NOTEIf your Web certificate is invalid or expired, you will be prompted to continue without the certificate or add anexemption to the certificate.The following are the default log on settings for the Base station Web-based interface:• Web-based interface access — https://192.168.101.2• subnetwork mask — 255.255.255.0•username — root• password — vistamaxTo log on to the Web-based interface:Step 1 Open a Web browser and open the Web-based interface by typing https://192.168.101.2 in the address bar. The Network Password page opens:NOTE192.168.101.2 is the default IP address that comes preconfigured from Vecima, but your IP address might be different.

The log on screen displays:
obr3650_ml_01_sdApproved: C.W.3-43.4 Configuring the NetworkYou will need to configure your network to establish communication between the network elements. Figure 3-2 shows an example of a properly configured network. The example shows a network configuration using default values. If you purchased a WiMAX starter kit, these value will already be set.The VistaMAX Base Station is shipped with a default IP address. However, depending upon your network configuration, you may want to change the IP address of your Base Station. Figure 3-2 Network DiagramAs per the WiMAX standard, the subscriber station requires an IP address and TFTP offered to it during network entry. To fulfill this requirement, both a DHCP and TFTP server must be present. It is possible to use a third-party customer-supplied DHCP and TFTP server, but Vecima recommends using the Network Management Server 8000 (NMS8000). Most Vecima starter kits come with an NMS as part of the solution.NOTECustomers who purchased the basic starter kit or who do not have an NMS must use the WiMAX-out-of-the-box(WOOTB) procedure. For more information about WOOTB, contact the Application Engineering Support atVecima Networks.To configure a network using NMS8000:Step 1 Open the base station graphical user interface (GUI) and click Configuration > Network Configuration. The Current Interfaces screen opens displaying the name, IP address, and netmask of the base station’s primary interface. The default value is 192.168.101.2. To modify this value, click br0 to open the BR0 configuration screen and type the new value in the appropriate field. See “To change the base station IP address“ below for a detailed description of this Step.Step 2 Using the NMS GUI, set up and enable DHCP on the NMS, then configure the subscriber stations and hostcomputers as required. NOTEFor more information see the NMS8000 & NMS8000/SSP Network Management Server Installation and Operation Guide.

Aobr3650_ml_01_sd Approved: C.W. A-1APPENDIXA1 Molex® Backshell InstallationA defect was detected with the Ethernet terminating end of the Molex®backshell packaged with the OBR3650. Theterminating modular plug allowed the shielding wire to be improperly grounded, thus making the cable susceptible toradiated interference. Without proper grounding, the presence of interfering radiation can cause the loss of data packetsbetween the OBR base station and the WES800.To fix this problem, Vecima recommends reworking the termination of the Ethernet cable using the JMRJ45S-15modular plug and properly grounding the cablefeed. The cable termination can be repaired in the field at the tower site.Once the Ethernet cable termination is repaired, the cable feed will no longer be susceptible to interfering radiation andthe data will be secured.Figure A-1 JMRJ45S-15 Modular PlugNOTEOther than the risk of data loss due to interfering radiation, there is no safety issues concerning the connectorthat came with the OBR3650. Where loss of data due to the radiating interference is not a concern, reworkingthe terminating end with the JMRJ45S-15 is only necessary as a precaution.If using a pre-made cable assembly (such as a CAT5CABLE/OD/25, CAT5CABLE/OD/50, CAT5CABLE/OD/75or CAT5CABLE/OD/100 from Vecima Networks), then the process described in this document is not necessaryCAUTIONBefore attaching the backshell, it is highly recommended that the user read throughthis entire appendix to become familiar with all of the steps involved to ensure thatnone are missed.

If you happen to take off all the foil,simply remove more of the jacket. When complete, 0.65 inches (or 1.7 cm) of intact foil should be exposedand the wires should extend another 0.85 inches (or 2.2 cm) beyond that. See Figure Figure A-4.Figure A-4 Stripped jacketStep 2 Untwist the wire pairs and separate them. Fold the stranded wire back over the foil. See Figure A-5 belowfor a picture of wires prepared for insertion into the connector sleeve.Figure A-5 Preparing the wires for insertion in connector sleeveStep 3 Insert each wire through the loading sleeve in the precise order shown in Figure A-6. Ensure that the foil isclosed around the wires and that the loading sleeve is pushed as far back on the cable as possible so thatit is close to the foil. Be sure to insert the wires into the open end of the loading sleeve. Trim the wires sothat the they extend from the foil by 0.4 inches (1 cm).

BAppendixobr3650_ml_01_sd Approved: C.W. B-1B1 Installing the Antenna - Points to ConsiderImproperly installed antennas will add cost, time, and frustration to your operation. Taking some time to plan a properinstallation will have long term benefits.B1.1 Planning the InstallationConsider the following points when planning an installation:• The antenna should support proper grounding and lightning protection.It is usually far easier to bring the coax into the building where the AC power enters the building; because this is theeasiest and cheapest way to properly bond the cable entrance to the AC ground (coax is easier and cheaper to workwith than #6 AWG copper). Any lightning energy coming in on the coax will be also shared and spread over to theAC ground system, and there will be no voltage differential between the two ground systems. • The antenna should be able to send and receive a strong signal. The simplest method is to presurvey the proposed location with an antenna and transceiver that are connected viaa temporary string of coaxial cable to a power inserter. The assembly can be mounted to any pole and hand–heldto determine the presence of signal using the integrated beeper.• The antenna should support your plan for cableruns.Cableruns that are too long might decrease the efficiency of signal transmission. Cableruns should be able tosupport proper grounding and surge protection. Make sure that you have determined the entire wiring route & needsbefore drilling holes in the structure and attaching mounting hardware.CAUTIONTo comply with RF exposure requirements, the integrated antenna or any external antenna which isconnected to an OBR3650 requires a minimum distance of 1.5 meters between it and all persons.B1.2 Safety ConsiderationsBefore you begin your installation, read all critical safety warnings. See Safety Precautions for more information.• Do not put the antenna under a power line. The power line can cause interference, and also exposes the Installationto unnecessary site hazards.• All Installations must meet building and electrical codes. Note that some municipalities have restrictions orcommunity covenants regarding towers and antenna structures. Check first.• Do not install the antenna in high winds or in stormy weather, particularly if lightning is present. • Remember to assemble the antenna hardware at a safe location before climbing up to the antenna mount.• Depending on your location, you may need two or more people to install the antenna and mount. B1.3 Evaluating the Mounting LocationYou can mount the antenna to a variety of surfaces.• The antenna should have a clear line-of-sight to the subscriber station. Do not put the antenna where it will beblocked by people, animals or vehicles. Consider how time and the season will affect the line-of-sight. For example, will foilage from growing trees interferewith the line-of-sight? Will wind or ice add strain to the mounting assembly?
obr3650_ml_01_sdApproved: C.W.B-2• The simple arm supplied with the integrated antenna assembly can be mounted to the side of the house if you canlocate the structural studding.The simple arm can also be attached to brick or cinder blocks. If mounting to brick, be sure to put the anchors in thebrick only, as anchors will not hold in joint mortar. If mounting to cinder blocks, use toggle bolts that go into the hollowspace in the block.• The rooftop will often be another spot to fasten to. This usually is the best location for obstruction clearance. Locatingunderlying truss structure can be done with stud finders, looking for nail fasteners through the fascia board, standardsounding techniques, or from the underside of the roof. To prevent the roof from leaking, you should caulk the holeswith silicone sealant around the holes and at the bottom of the antenna foot where it contacts the surface. Apply thesealant before you bolt the foot down tight. Be sure to caulk all holes to prevent leaks.• An independent radio tower can also be used, but the Installation of these towers is beyond the scope of thisdocument, usually involving professional structural engineering. Metal towers can provide some of the best lightningprotection since the large metallic structural elements will best carry lightning energy straight to ground.• Wooden poles are NOT recommended, because the insulating properties of the wooden pole mean that a largepercentage of a lightning stroke will follow the coax towards the terminal end, even when substantial groundingconductors are used. Also, wooden poles will sway in the wind putting the antenna beam in and out of alignment inhigh wind conditions. By the time the pole is re-guyed to minimize the sway; a properly engineered metal tower couldhave been installed.• Wind considerations. The integrated antenna has been engineered to operate in 160 Km (100MPH) winds, andsurvive in 220 Km (135 MPH) winds, but these forces will generate several hundred Kg. of load to the supportingmast. At this point, the mounting structure needs to be very secure.• The Installation should be accessible year round. Ice might build up in the winter or early spring time.TIPWhen the primary coaxial cable is placed, leave approximately 24” of coaxial cable with a 4” to 6” diameter loopwhere the antenna will be installed. This will allow for the required flexibility for adjustment and future servicing.
