Liberator-V1000 User Manual Rev 04v05 Page 6 of 85 FBN Doc #: FBN-0125_04v05 1. INTRODUCTION 1.1 Revision Fastback Networks & Sub10 Systems reserve the right to revise this User Manual and associated documentation periodically without any obligation to provide notification of such revision or changes. 1.2 Intended Users & Software Version This manual is intended for all installation and service personnel who are involved in the planning, installation, operation and maintenance of the Liberator-V1000 equipment. Although the Liberator-V1000 Link is designed for easy installation and setup, optimum performance can be achieved by following the procedures outlined in this manual. Use of this manual requires that the installer has at least a basic experience and understanding of networking equipment, as well as some familiarity with its configuration and operation. The information covered in this manual should be fully understood prior to installation. This Manual refers to Liberator-V1000 running Software Version 2.1.4.x. Please ensure that the software on the radio terminals is the latest version on the Fastback Networks website: http://www.fastbacknetworks.com Please email: support@fastbacknetworks.com if you encounter any issues. 1.3 Safety Information 1.3.1 Grounding The V1000 radio terminal (outdoor unit) must be properly grounded to protect against lightning strikes. It is the user’s responsibility to ensure that the equipment is installed in accordance with national regulations: USA: Articles 810 & 830 of the National Electric Code ANSI/NFPA No.70-1984 Canada: Section 54 of the Canadian Electrical Code Other countries may require different regulations. It is recommended that the outdoor unit be installed by a professional installer. 1.3.2 Operation in Hostile Environments The rated operating temperature of the radio terminal (that is, the outdoor unit or ODU), is from -40°C to +55°C. In normal operation, the radio terminal will be at a higher temperature than the ambient temperature. For safety reasons, if the ambient temperature at the location proposed for the radio terminal is likely to exceed +40°C, then the radio terminal must be mounted in a Restricted Access Location. The Restricted Access Location must only be accessible to authorised maintenance personnel through the use of a tool, lock and key or other security mechanism. The maintenance personnel must be advised that the radio terminal is hot and that safety precautions must be taken: either disconnect power from the radio terminal 1 hour before undertaking maintenance/repair, or else wear protective gloves when handling the radio terminal if power disconnection takes place less than 1 hour before access. 1.3.3 Exposure to Non-Ionising Radiation All radio transmitters emit non-ionising radiation and have to be assessed for the potential impact of the radiation levels on Human Safety. The radio terminal and antenna should always be mounted in such a way as to prevent human exposure to radio-frequencies, by ensuring that the following minimum safety distances are observed: Safety Distance = 1 metre on boresight. The antennas MUST be positioned to ensure that a minimum separation distance of 1 metre on antenna boresight is maintained between the installer or user and the antennas. The antennas MUST be positioned to ensure that no human being could be reasonably expected to come within 1 metre of the antenna during normal operation of the radio equipment. 1.3.4 Power Supply The Sub10 Systems PoE++ power injector should always be used to power the Liberator-V1000. If the correct power supply is not used, this may invalidate the safety certification and cause a safety hazard. The mains
Liberator-V1000 User Manual Rev 04v05 Page 7 of 85 FBN Doc #: FBN-0125_04v05 power supply is the primary disconnect device for the Liberator-V1000. The installer must ensure that a mains voltage supply cable approved for the country of installation is used. WARNING: It is strongly advised to first disconnect any network cable attached to the “IN” port of the PoE++ supply before:  Connecting or disconnecting the PoE++ supply from the mains power  Connecting or disconnecting the CAT5e cable between the PoE++ supply and the radio terminal (ODU). 1.3.5 Maintenance and Servicing  Always disconnect the primary power source before undertaking maintenance/repair of the radio terminal (Outdoor Unit).  At least once per year, each radio terminal (Outdoor Unit) must be inspected for signs of corrosion. Light corrosion is acceptable in extreme environmental conditions (marine-type deployments), but the structural integrity of the Outdoor Unit must not be in doubt. In the unlikely event that significant corrosion is seen, the radio terminal may need to be replaced: in this case, please contact Sub10 Systems for advice. 1.4 Warranty Sub10 Systems warrants to the original end user (purchaser) that this product is free from any defects in materials or workmanship for a period of up to 24 months (2 years) from the date of shipment to the end user.

Liberator-V1000 User Manual Rev 04v05 Page 8 of 85 FBN Doc #: FBN-0125_04v05 2. SYSTEM OVERVIEW 2.1 Top Level Description The Liberator-V1000 system operates as a data link in the unlicensed 60 GHz band between 57 GHz and 64 GHz. The antenna radome face measures only 18cm x 18cm (7” x 7”), making it ideal for unobtrusive urban deployments. The Liberator-V1000 is a Transparent Layer 2 Wireless Ethernet Bridge, and consists of two radio terminals. Each radio terminal is managed individually through a Web Management Interface or via the SNMP management protocol. 2.1.1 Versions There are two versions of the Liberator-V1000:  The Liberator-V1000 Single-port ODU has a single Gigabit Ethernet copper interface with PoE++ powering.  The Liberator-V1000 Dual-port ODU has an additional GigE copper interface (data only, non-powered), and also a SFP optical port: only one of these two additional data ports may be used at any one time. Figure 2 - Liberator-V1000 Single-port and Dual-port versions Table of differences between Single-port and Dual-port versions of Liberator-V1000: Feature Single-port Dual-port Software version All Software releases may be used Only software releases from 2.1.4.1 onwards may be used Ports Single port (PoE & GigE combined) Primary port: PoE & GigE combined Secondary port copper: GigE data port Secondary port SFP: Optical data port Although both secondary data ports are available on the terminal, only one of the secondary data ports may be used at a time. If both secondary data ports are connected, then the Secondary copper port will have priority and the Secondary SFP port will be inactive. It is not possible to use both secondary data ports at the same time. RJ45 Seal Kit Required to connect onto the flying lead. RJ45 seal kit and rain cover / hood are not needed (not Figure 1 - V1000 radio terminal
Liberator-V1000 User Manual Rev 04v05 Page 9 of 85 FBN Doc #: FBN-0125_04v05 The supplied rain cover / hood should always be fitted over the RJ45 seal kit to prevent water ingress. supplied). The data ports have sockets with water-proof glands instead of a flying lead. Ice bridge The radome requires protection from hailstones: recommend to fit standard single-port ice bridge (unless radio terminal is mounted in an exposed / windy location). The new polycarbonate radome is resistant to hailstone damage. Dual-port ice bridge is an optional accessory. Single-port ice bridge cannot be used. Alignment scope Single-port terminal will accept all versions of alignment scope. Dual-port version will only accept alignment scopes shipped from September 2015 onwards. Older versions of alignment scope are not compatible, and will require a new scope mounting bracket: please contact Fastback Networks Support. Polarization marking Arrows on the back of the radio terminal point either vertically or horizontally, and must be in the same orientation at both ends of the link. Two black dots on the front of each antenna frame: these are either at the top & bottom or else at left & right of the radome, and must be in the same orientation at both ends of the link. Frequency Channels Supports 3 non-overlapping channels in both uplink and downlink. All combinations of uplink and downlink channels are allowed. Supports 4 non-overlapping channels in both uplink and downlink. All combinations of uplink and downlink channels are allowed. Timing Basic SyncE Full SyncE and IEEE 1588v2 Encryption Most Single-port radios are not hardware-capable for encryption. All Dual-port radios are hardware-capable for encryption, which is dormant. Dormant encryption can only be enabled with a software licence key, which must be purchased from Fastback Networks. Inter-operation A Single-port radio terminal will only make a radio link with another Single-port terminal. A Dual-port radio terminal will only make a radio link with another Dual-port terminal. 2.1.2 Features & Benefits • Easy installation – The concept of the Liberator-V1000 Link allows the end user to install it as easily as any other network component. The single cable solution reduces the complexity of the installation. The terminal is connected to the network, monitored and supplied with power through a single outdoor industrial-rated CAT 5e Ethernet cable, which has a solid or multi-braided screen. • A visual alignment tool together with an alignment bracket allows the user to easily line-up the antennas. Subject to correct installation techniques being used, immediate operation without the need for additional configuration is assured. • Network performance – Guaranteed 500Mbps, 700Mbps or 1Gbps full-duplex with Licence Key. • V-band licence-free operation – The system has been approved and can be operated in many countries without needing an individual regulatory licence for each link. Always check in-country regulations which may vary. • System administration – To monitor the status and the traffic, the user can access the link statistics either via the HTML user interface or by integrating it into a network management tool via SNMP. • Security – The coding applied to the proprietary radio interface significantly restricts access to the 60 GHz transmitted data. Additionally a high level of data security is inherent in the product via signal absorption by atmospheric oxygen and the use of high gain/narrow beamwidth antennas. The Dual-port version is hardware-capable for upgrade to AES-256 encryption using a licence key. • The Dual-port version of Liberator-V1000 allows the user to operate with a second data port (either copper or fibre). 2.1.3 Encryption
Liberator-V1000 User Manual Rev 04v05 Page 10 of 85 FBN Doc #: FBN-0125_04v05 AES-256 encryption is available via Licence key upgrade, but only in countries where regulations permit, and only on units already fitted with AES-capable hardware (some Single-port and all Dual-port versions). Maximum encrypted capacity is 700Mbps full-duplex. 2.1.4 Applications • LAN extension • Redundant access • Campus connectivity • Disaster recovery • Wireless backhaul • Centralization of IT infrastructure • Temporary connections during events • Mesh, hub and spoke configuration 2.2 Ethernet Switch Each radio terminal includes an Ethernet switch. The first switch port is connected to the physical Ethernet connection to the terminal. The second switch port is connected to the radio modem and the terminal’s management agent. The switch transparently passes all Layer 3 protocol messages. For example, the switch does not implement any kind of Spanning Tree Protocol (STP): it will simply pass all STP messages transparently over the air, but will not perform any routing of data traffic based on the Spanning Tree. This means that all incoming packets on the Ethernet interface are simply passed over the air, without taking any account of STP, and therefore the installer should ensure that there are no data loops in the system, because the switch will not detect the existence of a loop. The single-port version of Liberator-V1000 does not support MAC address learning, but simply re-directs packets that are addressed to the management agent. All other packets are sent over the radio. In the dual-port version of Liberator-V1000, the switch is capable of learning up to 1024 MAC addresses to switch between the 2 ports. Any packets addressed to the management agent are redirected, and all other packets are sent over the radio. Figure 3 - Network layers of the V1000 system

Each terminal is connected to the network via an Ethernet cable (to outdoor specification) with RJ-45 connectors. Power is supplied to the terminal through the Ethernet cable. Figure 6 (a) V1000 Single-port Terminal (b) V1000 Dual-port Terminal 2.3.2 Alignment Bracket The alignment bracket facilitates easy radio alignment owing to its independent axes. It has a locking nut on each axis, so that once aligned on one axis, the alignment will not be disturbed by adjustments to the other axis.
Liberator-V1000 User Manual Rev 04v05 Page 13 of 85 FBN Doc #: FBN-0125_04v05 Figure 7 – Alignment Bracket 2.3.3 PoE++ Injector The terminal is powered via an Ethernet cable with a high-power Power-over-Ethernet power supply conforming to “Ultra-PoE” or “PoE++” specifications. It is recommended that the Sub10 Systems PoE++ power injector should always be used to power the Liberator-V1000. If the correct power supply is not used, this may invalidate the safety certification and cause a safety hazard. The mains power supply is the primary disconnect device for the Liberator-V1000. The installer must ensure that a mains voltage supply cable approved for the country of installation is used. WARNING: It is strongly advised to first disconnect any network cable attached to the “IN” port of the PoE++ supply before:  Connecting or disconnecting the PoE++ supply from the mains power.  Connecting or disconnecting the CAT5e cable between the PoE++ supply and the radio terminal (ODU). Should the network equipment connected to the Liberator-V1000 Link not offer PoE++, a power injector can be inserted in-line with the Ethernet cable. Figure 8: (a) SL Power PENT 1040B PoE++ power injector (b) PhiHong POE61W PoE++ power injector 2.3.4 Mast Bracket The mast bracket is used to mount the bracket onto a mast. The bracket is suitable for any pole diameter from 50 mm to 115 mm (2” to 4.5”).
Liberator-V1000 User Manual Rev 04v05 Page 14 of 85 FBN Doc #: FBN-0125_04v05 Figure 9 – Mast Bracket 2.4 Accessories and Spares (available to order as additional parts) The parts listed in this section are not included with each link, but must be ordered separately if required. 2.4.1 Optical Alignment Tool The optical alignment tool provided is easily mounted on the terminal using the locator pins and large thumbscrew. It enables both ends of the link to be coarsely-aligned quickly, simply and independently. Note that customers who purchased an optical alignment scope for use with Liberator V320 in the past, may find that the scope does not mount onto the V1000 back-housing. An adaptor plate is available for these early-version optical scopes, please contact your distributor, or else Sub10 Systems Customer Support. The first version of the optical alignment tool only fits the single-port radio. The current version fits both single-port and dual-port radios. Both are shown below. Figure 10 Optical Alignment Tools (a) Single-port only (b) Single & Dual-port 2.4.2 Surge Arrestor The surge arrestor is placed between the radio head and the Ethernet cable connecting to the PoE and any other network infrastructure. This device helps to reduce the risk of damage from lightning or high-tension overhead equipment. Note: Fastback Networks / Sub10 Systems does not supply a surge arrestor with each link, but can recommend one on request.

Liberator-V1000 User Manual Rev 04v05 Page 16 of 85 FBN Doc #: FBN-0125_04v05 3. SITE PLANNING All installers must perform a full site inspection and plan carefully prior to the physical installation of a Liberator-V1000 link. This preparation must include: • Evaluating the most appropriate location for the installation of the terminal. • Identifying an appropriate mounting structure (wall or mast) for each terminal. • Planning the cable routing from the network component to the terminal. 3.1 Terminal Location When selecting the best terminal location the following factors should be considered: • Accessibility (e.g. How to gain access to a roof) • Type of mounting (e.g. wall or pole) • Grounding connection point • Cable runs (max. 100 m / 328 ft) • Human safety: Exposure to Non-Ionising Radiation - The Liberator-V1000 terminal should be mounted so that it is always separated from the location of any human being by a distance of at least 1 metre. 3.2 Line of Sight To ensure a clear line of sight (LOS), there must be no obstructions between the two terminal locations: the first Fresnel Zone should be completely clear of obstacles, see diagram below, with n=1. The required clearance can be established visually, or by using the table below which gives the worst-case clearance at the centre-point of the link. This table is valid for distances greater than about 4 metres from the radio terminal. Note that this is the minimum clearance distance with perfect antenna alignment. It is recommended to use the widest clearance distance around the LOS path as is practically possible. Table 1 - Fresnel zone clearance for different ranges at 60GHz Link Distance Boundary Diameter (2F1) 100 m 328 ft 0.7 m 2.3 ft 200 m 656 ft 1.0 m 3.3 ft 400 m 1312 ft 1.4 m 4.6 ft 600 m 1968 ft 1.7 m 5.6 ft 800 m 2625 ft 2.0 m 6.6 ft 1000 m 3280 ft 2.2 m 7.3 ft The figure below shows required clearance at close proximity to the antenna. Figure 13 – Fresnel Zone Clearance at 60 GHz
Liberator-V1000 User Manual Rev 04v05 Page 17 of 85 FBN Doc #: FBN-0125_04v05 3.3 Link Distance / Link Availability The link distance is directly related to the weather conditions. Optimum link range and availability is influenced by the following environmental conditions: • Rainfall - the lower, the better • Oxygen absorption – This ranges between about 14 and 16 dB/km, depending on temperature and atmospheric pressure An accurate estimation of the total link distance (line of sight) is important in estimating link range and quality. For the rain regions in your country, see appendix A.4. 3.4 Terminal Mounting Options 3.4.1 Wall Mounting The wall mounting location should be strong enough to secure the terminal to the wall, taking into account all foreseeable environmental conditions (e.g. wind, rain, ice). Depending on the material to which the bracket is mounted, differently-sized mounting hardware may be necessary. To mount the terminals onto the bracket use the enclosed M6 bolts. The bracket allows a tilt angle of +/- 50° in both axes. 3.4.2 Pole Mounting The mast mount bracket will be needed to mount the terminal onto poles with diameters from 50 mm to 115 mm (2” to 4.5”). 3.5 Lightning Protection Zones In order to protect against lightning strikes damaging the equipment, it is important to choose a mounting position for the radio terminal (ODU), which is located in a “Protected Zone”. In order to determine the zone of protection against lightning strikes, the rolling sphere method is commonly-used. In this method, an imaginary sphere is rolled-over the top of the building or mast: regions underneath the lower trajectory of the sphere are in the protection zone, whilst areas above this are in danger of a lightning strike which can damage equipment and be hazardous to life. The imaginary rolling sphere can only be elevated by lightning finials, “air terminations” or adequately-grounded metallic structures, (not simply by the edge of a roof which has no earth bond). The radio terminal should always be installed in a Protected Zone. The radius of the rolling sphere depends on the level of lightning protection required, which varies between geographical areas. See the table below for details. A commonly used value for the sphere radius is 45 metres, but this will depend on the level of protection needed. Table 2 - Lightning Protection Levels and Sphere Radius Lightning Protection Level Sphere radius (m) Interception Current (kA) 1 20 2.9 2 30 5.4 3 45 10.1 4 60 15.7
Liberator-V1000 User Manual Rev 04v05 Page 18 of 85 FBN Doc #: FBN-0125_04v05 Figure 14 – Rolling Sphere Method for Determining Lightning Protection Zone 3.6 Cabling The terminal is delivered with an Ethernet cable terminated with a RJ-45 connector. To connect the Liberator-V1000 radio terminal to your network, use a Cat 5e Ethernet cable with a maximum length of 100 metres to the next network node. The recommended cable specifications are: • CAT5e Cable • Outdoor Industrial Rated (includes rating for UV protection) • Solid or Multi-Braided Screen (avoid cables with a metalised plastic foil screen) • Screened RJ45 Connectors Since the power is supplied by the Ethernet cable, please make sure that network equipment used supports power over Ethernet to the “Ultra PoE” or “PoE++” specification. 3.7 Co-located Applications Owing to the compact size of the Liberator-V1000 integrated terminal, it may be used for co-sited applications (see the section titled Co-located Terminals). Return to Table of Contents
Liberator-V1000 User Manual Rev 04v05 Page 19 of 85 FBN Doc #: FBN-0125_04v05 4. Installation Owing to the small size and integrated design of the Liberator-V1000 Link, correct installation and setup is relatively simple. When working on a roof, ladder, mast or staging, please take extreme care, observing all facility and OSHA (or other applicable regulatory agency) required safety precautions. 4.1 Wall Mounts & Mast Mounts 4.1.1 Wall Mount The wall and mounting screws must be able to support a weight of 11 pounds (5 kg), taking into account associated wind and potential ice loading factors. 4.1.2 Mast Mount The alignment bracket with V1000 radio terminal attached is shown below. Figure 15 - Alignment bracket • Ensure that the mast has a diameter of between 50 mm to 115 mm (2” to 4.5”), or else a collar may be required to adapt to the mast bracket. • Fasten the mast bracket onto the mast using the enclosed stainless steel bands • Fasten the alignment bracket onto front part of the mast bracket using the enclosed stainless steel screws, nuts and washer (M6 size screws which require a 4.5mm Allen Key tool which is included). To adjust and lock the bracket using the M8 alignment bolts, a 6mm Allen Key tool is required. NOTE: Do not use zinc-plated screws / bolts as these will corrode and endanger link performance and safety to people and equipment. 4.2 Terminal Installation 4.2.1 Terminal Installation – Polarization It is important to install the terminal on the bracket with the same orientation (antenna polarization) at both ends of the link. The terminals must be mounted on the brackets in such a way that the polarization arrows point in the same direction: either both ends pointing vertical, or else both ends pointing horizontal (these are actually 45 degree slant polarizations). On Single-port versions, the polarization is indicated by an arrow on the backhousing, as shown below. Note that the “A” terminal has the drop cable entry point on a different corner of the radio housing compared to the “B” terminal.

Figure 17 - V1000 Dual-port Backhousing with black dots indicating polarization direction The terminal must be mounted on the bracket using the enclosed stainless steel screws (M6 x 12). NOTE: Do not use zinc-plated screws as these will corrode and endanger link performance and safety to people and equipment. 4.2.2 Terminal Installation – Configuration of Co-located Terminals If radio terminals are sited together in a cluster, configure the links to minimise interference by:  Swapping Tx High / Low (Swap A and B terminals).  Swapping polarization (Rotate radio terminals by 90 degrees so that arrows are swapped vertical / horizontal).  Using different frequencies (Choose from 3 non-overlapping channels on Single-port and 4 non-overlapping channels on Dual-port).  Physically separating the terminals by at least 1 metre. For dense networks, especially with multiple clusters terminating on a single building, it is advisable to perform frequency planning prior to installation of the links: Fastback Networks have a planning tool to help with this, or else an industry-standard tool such as Pathloss may be used. Fastback Networks can supply Pathloss configuration files on request.
Liberator-V1000 User Manual Rev 04v05 Page 21 of 85 FBN Doc #: FBN-0125_04v05 4.3 Grounding The terminal must be properly grounded. Two screws are provided on the rear housing of the terminal to facilitate correct grounding. To fasten the grounding cable onto the terminal, use a screw post and serrated washer combined with an M8 nut. Connect the terminal to the connection points nearest to the building-to-earth ground point. The grounding conductor must be as short as is practical and should not exceed 6 metres (20 ft). For installations in the USA, refer to Articles 810 and 830 of the National Electrical Code. For installations in Canada, refer to Section 54 of the Canadian Electrical Code. For installations in all other countries, refer to the in-country safety standards and regulatory requirements. 4.4 Cable Installation The length of the cable from the terminal to the next network component may be up to 100 metres (328 ft), but should be kept as short as practical in order to reduce voltage drop and signal loss. All Ethernet cables must be CAT 5e compliant and suitable for outdoor use. The cable must be UV stable and UL approved and must comply with local and/or national building codes. Cables should be shielded for outdoor use. 4.4.1 Terminating the Cat5e cable with the cable gland (Dual-port version only) When terminating the Cat5e cable with the Dual-port version of V1000, it is important to follow the correct procedure for attaching the cable gland to the Cat5e cable. a) Attach the RJ45 plug to the Cat5e cable, with the metallic screening foil or braid section exposed, starting at 35mm from the end of the RJ45 plug, right up to 50mm from the end of the plug. Figure 19 - Expose the cable screen starting at 35mm distance, and running up to 50mm from end of plug b) Push the RJ45 plug into the ODU socket, and make sure that it snaps into position c) Support the Cat5e cable, and gently screw the gland body into the ODU enclosure by hand, until the rubber “O”-ring is flush with the metal enclosure. Tighten the gland body with a 24mm spanner. Do NOT fit the back shell of the gland before the main body of the gland is secure. d) Once the main body of the gland is secure, then tighten the back shell of the gland onto the gland assembly, but do not over-tighten, to avoid damaging the inner seal. 4.4.2 Selecting the correct port for PoE Supply (Dual-port version only) The Dual-port version of Liberator-V1000 has 3 ports (2 GigE copper ports, and 1 port for fibre SFP which is the largest port aperture). The PoE supply must ONLY be connected to the port marked “PoE” as shown below. The second GigE copper port cannot be used for powering, as it is for data only. Figure 18 - Grounding post on V1000 terminal
Liberator-V1000 User Manual Rev 04v05 Page 22 of 85 FBN Doc #: FBN-0125_04v05 Figure 20 - Port locations on V1000 Dual-port 4.5 Power Injector The power injector is connected in-line with the data line. The maximum distance between the PoE injector and the Liberator-V1000 Link is 100 metres (328 ft). The PoE injector must be compliant with “Ultra PoE” (PoE++). To check that the injector is functioning correctly, use a PoE Tester. WARNING: It is strongly advised to first disconnect any network cable attached to the “IN” port of the PoE++ supply before: (a) Connecting or disconnecting the PoE++ supply from the mains power (b) Connecting or disconnecting the CAT5e cable between the PoE++ supply and the radio terminal (ODU). Figure 21 (a) - SL Power PENT 1040B PoE++ (b) PhiHong POE61W PoE++ 4.6 Antenna Alignment Accurate antenna alignment is extremely important to achieve the maximum rain fade margin for the link. One of the Liberator-V1000’s biggest advantages is its fast, easy alignment procedure. The terminals can be aligned optically by using an optical alignment tool (shown below). Electrical alignment is then used to optimize performance, using a Digital Voltmeter (DVM) connected to the alignment port on the back housing of the terminal. The first version of optical alignment scope (shown in part (a) of the figure below) can be
Liberator-V1000 User Manual Rev 04v05 Page 23 of 85 FBN Doc #: FBN-0125_04v05 used only with a single-port V1000. The current optical alignment scope (shown in part (b) below) can be used with single-port and dual-port V1000. Figure 22 Optical Alignment Scopes (a) Single-port only (b) Single & Dual-port Graphs in Appendix A give the required alignment voltage for a given RSSI value and a given range. Note that the values of alignment voltage for a given range are only average values, assume clear air conditions, and will vary slightly with geographic location. Therefore for the most accurate voltage prediction, it is strongly encouraged to use the Liberator-Predict Link Calculator, available from the Fastback Networks website. The table below shows alignment tolerance in terms of absolute position. However, it should be noted that since all alignment is dependent on the angle subtended at the alignment bracket, the distance of the link is not a factor in determining the required tolerance on the alignment angle, which should be the same for all ranges. Figure 23 – Alignment Positional Accuracy 4.6.1 Alignment Procedure The following procedure achieves fast, accurate alignment. For mounting onto the pole, the supplied 4.5 mm Allen key can be used. For fine antenna alignment, a 6mm Allen-Key / T-Bar tool is required (not included) to adjust the M8 alignment bolts. (a) Using the Alignment Bracket Use a 6mm Allen-Key / T-bar tool to adjust the M8 bolts on the alignment bracket in azimuth and elevation and repeat until fully aligned. Then lock-off using the M8 locking bolts for azimuth and elevation. These steps are illustrated in the figures below.
Liberator-V1000 User Manual Rev 04v05 Page 24 of 85 FBN Doc #: FBN-0125_04v05 Figure 24 - (a) Horizontal (azimuth) adjustment screw (b) Vertical (elevation) adjustment screw Figure 25 - (a) Locking the horizontal position (b) Locking the vertical position (b) Optical alignment • Place the alignment tool on the most accessible corner of the radio unit and ensure good visibility to the opposite terminal by rotating the viewfinder. • Use a 6mm Allen-Key / T-Bar tool to orientate the bracket in to a position where the alignment scope shows the target location is in the cross hairs. • Once this is completed correctly at both end, you will be able to measure a Voltage via the DC port (Power Level Alignment) (c) Alignment using a voltmeter to read RSSI Following optical alignment, an alignment based on the received power level of each terminal should be performed. Use a voltmeter and cable with a female QMA connector to attach to the QMA connector on the terminal of the procedure for optical alignment, and adjust the alignment bracket to obtain maximum voltage from each terminal.
Liberator-V1000 User Manual Rev 04v05 Page 25 of 85 FBN Doc #: FBN-0125_04v05 Figure 26 - Connection of a voltmeter for fine alignment on Liberator-V1000 The Alignment Interface is to allow the connection of a voltmeter during terminal installation. During installation a DC voltage between 0.5 and 4V is output, which is proportional to the receive signal strength. The higher the voltage, the higher the receive signal strength (RSSI). See Appendix A.2.3 for graphs of the RSSI voltage. Figure 27 - Alignment voltage vs. RSSI (see Appendix A.2.3) Follow the scanning pattern example below to find the peak voltage on the voltmeter; you must follow this pattern fully to ensure that you are not aligning on to a side lobe of the antenna. The main beam is 15 dB higher than the side lobes and in clear line of sight is obvious when found. Figure 28 – Scan Pattern to Use During Alignment
Liberator-V1000 User Manual Rev 04v05 Page 26 of 85 FBN Doc #: FBN-0125_04v05 4.7 Factory-Defaulting a Terminal Factory-defaulting a terminal may occasionally be necessary to regain access to the unit if the master password is lost, or if it is desired to quickly reset all GUI settings to default. Note that any Licence Key which has been applied to the terminal will also be lost on factory default, and will need to be re-entered to re-activate the Licensed features. (a) The reset procedure below only functions when the terminal is in “Normal” Mode, it will not function when the terminal is in “Alignment” mode. If it is suspected that the terminal is in “Alignment” mode, and does not respond to the reset procedure, then it is necessary to ensure that it is definitely not in “Alignment” mode by either: 1. If the GUI webpage is contactable: Make sure that the alignment cap on the terminal case is closed. Browse to the “Home – Administration – Installation” page on the GUI, and if necessary click on “Change Mode” if the display is showing “Alignment mode”. The terminal should now be in “Normal Mode”, and this should be displayed on the GUI webpage. 2. If the GUI webpage is not contactable: Make sure that the alignment cap on the terminal case is closed. Power cycle the radio terminal, and it should now restart in “Normal Mode” if the alignment cap is already closed when the power is re-applied. (b) When it is certain that the radio terminal is in “Normal Mode” (and not “Alignment Mode”), then the following procedure can be used to restore the radio terminal to factory default settings: Short-out the Alignment interface and then remove and re-apply the short four times with 1 second mark space ratio, as shown below. Shorting-out the alignment port can be achieved either by using the protective Alignment Cap fitted, as this acts as an electrical short-circuit when closed, or else by shorting-out the plugs on the voltmeter alignment cable used for installation. If the radio terminal does not reset itself, it may be that the sequence was counted either too slowly or too quickly: there needs to be 1 second between each short-circuit or open-circuit change, as shown in the timing diagram. (c) Note that if the Alignment Cap is disconnected for a period of more than 30 seconds, then the radio terminal will automatically switch into “Alignment Mode”, see (a) above. Therefore it is recommended to always keep the Alignment Cap connected, except when physically aligning the link. Figure 29 - Reset Sequence Using the Alignment Cap
Liberator-V1000 User Manual Rev 04v05 Page 27 of 85 FBN Doc #: FBN-0125_04v05 If the IP address has been lost, then it is possible to re-discover the IP address by using a packet-sniffer tool such as WireShark, and power-cycling the terminal with WireShark running (always take care to have the network cable disconnected during the power cycle, and quickly re-connect it immediately after restoring power). A “Gratuitous ARP” containing the IP address will be sent from the terminal on start-up, which can be seen with WireShark. Please contact Fastback Networks Support for assistance with factory-defaulting a terminal. 4.8 Maintenance Warnings: • Always disconnect the primary power source before undertaking maintenance/repair of the radio terminal (Outdoor Unit). • At least once per year, each radio terminal (Outdoor Unit) must be inspected for signs of corrosion. Light corrosion is acceptable in extreme environmental conditions (marine-type deployments), but the structural integrity of the ODU must not be in doubt. In the unlikely event that significant corrosion is seen, the unit may need to be replaced: in this case, please contact Fastback Networks for advice. Return to Table of Contents

Parameters displayed are: • Transmit Power: Transmit power is only displayed in dBm, but the settings available are limited to “High / Medium / Low”, as in the table below: Tx Power Setting QPSK (700Mbps max) Nominal Average Tx Power into Antenna 8PSK (1Gbps) Nominal Average Tx Power into Antenna High +7.5dBm (FCC) and +6 dBm (Rest of World) +4 dBm Medium +3 dBm -1 dBm Low -5 dBm -5 dBm • RSSI (dBm): Received power at the antenna port (inside the ODU). • Vector Error (dB): This is a measure of the signal quality, and should ideally be lower (more negative) than -10dB (the exact value may vary over time). • MWU Temp (Celsius): This shows the operating temperature of the microwave unit inside the radio • Air Frame Error Ratio: This shows the % error rate over the air • Ethernet Rx / Tx (Mbps): This shows the user traffic rate on the Ethernet interface For each parameter, the local side of the link displays values for the Minimum, Mean, Maximum and Current, while the remote side of the link only displays the Current parameter value. The values may be reset by pressing the “Reset” button (which is useful after a power outage event, for example). The refresh speed can be increased by typing in a smaller number of seconds, as desired, into the “Page Refresh Interval” box, and then pressing the “Change” button.

This page indicates the Ethernet line-rate and whether it is active or not, and the status of the auto-negotiation. The Ethernet port parameters for the remote end of the link are also shown, and are coloured RED if there is no Ethernet cable connected at the remote end. Dual-port versions display a second box for Ethernet Interface 2. Figure 39 - LAN (Ethernet) Interface Note: On Dual-port versions, there is an option to choose the Switch Mode as either “Normal” or “Bypass”. Bypass mode forces frames on both Primary and Secondary ports to be sent over the air interface, and does not allow traffic to be switched between Primary and Secondary ports. The reason for choosing “Bypass mode” is to allow unicast traffic to traverse across the radio link, even if there is no entry in the Switch Address Lookup Engine. For TCP traffic where bidirectional frames will populate the Switch Address Lookup Engine, it is possible to use “Normal” mode which will also allow switching between Primary and Secondary data ports. 5.4.2 Administration – VLAN Configuration
Liberator-V1000 User Manual Rev 04v05 Page 38 of 85 FBN Doc #: FBN-0125_04v05 The user data traffic may be configured to support VLAN tags. Note that for management signalling, the VLAN ID is set on GUI page: “Administration / Management / IP”. When using VLAN’s the VLAN ID may be set to any value from 1 up to 4095. There are 4 possible scenarios when using VLAN’s: Case 1: VLAN’s not used Case 2: VLAN for Management only Case 3a: VLAN for Management + VLAN’s for User Traffic Case 3b: VLAN for Management + VLAN’s for User Traffic with Tag / Untag on Default VLAN NOTE: The “Allowed VLAN’s” table must always list the same set of VLAN ID’s on both ends of the link. 5.4.2.1 Case 1: VLAN’s not used In this case, VLAN’s are not used, and the VLAN table is empty (or the “Enable VLAN Filtering” box is unticked) on both sides of the link. Figure 40 - VLAN’s not enabled (Allowed VLAN tables empty, or not enabled) 5.4.2.2 Case 2: VLAN for Management Only In this case, VLAN is used for Management only (VLAN ID 99). All User Traffic is accepted, (both Tagged and Untagged), while the VLAN ID 99 is only used for Management traffic). The “Enable VLAN Filtering” box is unticked in the second figure below. Although the VLAN filtering is inactive, the Management VLAN ID 99 is still shown in the “Allowed VLAN’s” table for clarity.
Liberator-V1000 User Manual Rev 04v05 Page 39 of 85 FBN Doc #: FBN-0125_04v05 Figure 41 - VLAN 99 used for Management only, with User Traffic both Tagged & Untagged Figure 42 - Management VLAN only, with VLAN filtering not enabled 5.4.2.3 Case 3a: VLAN filtering enabled, with VLAN for management In this case, VLAN’s are used, and the VLAN table must contain the same VLAN ID’s on both sides of the link. Note that in order to enable VLAN filtering, it is first necessary to set-up the Management VLAN, which is set on GUI page: “Administration / Management / IP”. In the figure below, VLAN ID’s 10, 11 and 12 are for User Traffic, and VLAN ID 99 is for Management Traffic, and these VLAN ID’s are set to the same values on both
Liberator-V1000 User Manual Rev 04v05 Page 40 of 85 FBN Doc #: FBN-0125_04v05 ends of the link, also see the GUI screenshot below (the order of VLAN ID’s in the “Allowed VLAN’s” table does not matter). With this VLAN configuration, only user traffic on VLAN ID’s 10, 11 and 12 will be transported across the link, together with Management Traffic on VLAN ID 99, whilst all other traffic will be discarded (packets either untagged or else tagged with any other VLAN ID not listed in the tables). If the Management VLAN 99 is removed from the “Allowed VLAN’s” table, with VLAN filtering enabled, this will still allow management of the local side of the link, but it will prevent management of the remote end of the link, because the Management traffic will be filtered out and therefore not transported over the air to the remote terminal. Figure 43 - VLAN filtering with Management VLAN ID 99
Liberator-V1000 User Manual Rev 04v05 Page 41 of 85 FBN Doc #: FBN-0125_04v05 Figure 44 - VLAN filtering with Management VLAN ID 99 5.4.2.4 Case 3b: VLAN’s used with VLAN for management and default VLAN (Tag / Untag) This case is the same as Case 3a, but with the additional step of performing Tag / Untag manipulation on a single VLAN ID only. In this scenario, one of the User Traffic VLAN’s is also specified to be the DEFAULT VLAN at one end of the link only: at the end where the DEFAULT VLAN is enabled, all incoming untagged frames into the Ethernet port will be tagged with the VLAN ID of the DEFAULT VLAN before sending over the air to the remote side as Tagged frames. All frames Tagged with the DEFAULT VLAN ID which arrive over the air from the remote terminal will be stripped of their VLAN Tag before being sent out on the Ethernet port as Untagged frames. Note that both ends of the link must contain the same list of VLAN ID’s in the “Allowed VLAN’s” table, but the DEFAULT VLAN can only be enabled at one end of the link at any one time. See the figures below, where VLAN ID 99 is used for Management, VLAN ID’s 10, 11 and 12 for User Traffic, with VLAN ID 10 being set as the DEFAULT VLAN, and therefore performing the Tag / Untag operation on Terminal “B”. Note that it is possible to configure a DEFAULT VLAN ID at both ends of the link, (which may not be identical), but this represents an unlikely network configuration and is therefore normally unnecessary.

QoS has 8 priority queues, with queue 7 being the highest priority queue. The priority level of an incoming packet is set by the PCP bits of the VLAN, and it is possible to map multiple values of PCP bit settings to a single QoS queue if so desired. The priority level of an incoming packet is set by the PCP bits of the VLAN. The scheduling algorithm is Strict Priority only.
Liberator-V1000 User Manual Rev 04v05 Page 43 of 85 FBN Doc #: FBN-0125_04v05 Figure 47 - QoS Settings After setting the QoS parameters, it is necessary to click on “Apply”, and then to reboot the terminal for any changes to take effect. This allows both terminals to be set to the correct settings before QoS filtering is performed on the traffic. 5.4.4 Administration – Radio This page is used to control the radio interface: it displays the radio parameters for both the local and remote sides of the link, and allows the user to make changes. Please note that any changes made to either Transmit Power or Channel Selection must be carefully considered before making any changes, as it may result in the radio link going down, and therefore the remote side will no longer be contactable. Firmware version 02.01.03.01 and later supports a rollback feature, so that any changes to certain configurations including Tx Power or Frequency require a confirmation within a pre-defined expiry time (default 3 minutes): this is a failsafe mechanism so that if the requested change caused the link to drop then the setting will automatically be rolled-back to its previous value if left unconfirmed until the expiry time is reached. For a list of all configuration that is subject to confirmation and potential rollback see section Configuration Rollbacks. The Transmit Power Limit section can be used to set the power to either: High, Medium or Low. Tx Power Setting QPSK (700Mbps max) Nominal Average Tx Power into Antenna 8PSK (1Gbps) Nominal Average Tx Power into Antenna High +7.5dBm (FCC) and +6 dBm (Rest of World) +4 dBm Medium +3 dBm -1 dBm Low -5 dBm -5 dBm The transmit power should typically be reduced on shorter links (less than 150 metres) to ensure that the RSSI is not higher than -25dBm wherever possible. Please use the Link Availability Calculator to work out the correct link budget for your link before changing the Transmit Power, which should be the same on both ends of the link. Enabling ATPC (Automatic Transmit Power Control), will allow the transmit power to be dynamically adjusted by the radio in response to changing propagation conditions (e.g. rain fade). The transmit power will never move above the level set by the Transmit Power Limit. Always press “Submit”
Liberator-V1000 User Manual Rev 04v05 Page 44 of 85 FBN Doc #: FBN-0125_04v05 after making any changes to ensure that the change is applied to the radio. ATPC is disabled by default on V1000 radios. ATPC is always disabled when in “Alignment Mode”. Note that in Firmware Release 02.01.03.012, the maximum Tx power in 8PSK mode is +2dBm. The usable range with this Firmware release for 8PSK is from 30 metres up to 450 metres maximum. The Modulation Mode can be used to change modulation mode between fixed QPSK (up to 700Mbps) and 8PSK (1Gbps) AMOD. When 8PSK mode is selected, a slow adaptive modulation (AMOD) algorithm will automatically choose between QPSK and 8PSK according to the changing condition of the radio link. When QPSK mode is selected, AMOD is turned off. The Link Availability of the Modulation Mode may be changed using the drop-down menu to select either “High”, “Medium” or “Low” availability (default is “Medium”). This Availability setting changes the AMOD threshold: if Link Availability is set to “Low” this means that the AMOD threshold is set at a lower level so that the link will transition to 8PSK mode much more easily. If Link Availability is set to “High”, then the link will be biased more to remaining in QPSK mode, and will only transition to 8PSK mode with a much higher incoming signal level. Note that, on units fitted with AES capable hardware, if a valid AES Licence Key is applied, and AES encryption is activated, the modulation will be locked to QPSK mode only with a maximum throughput rate of 700Mbps. In this case, the AMOD setting options will not be displayed. If the capacity key is only 700Mbps or lower, then it is recommended to set the modulation mode to QPSK in order to avoid unnecessary changes up to 8PSK mode which will not increase the usable data rate if the Air Data Rate is 700Mbps or less. Figure 48 - Home Page showing the Air Data Rate (in this case set to 1000 Mbps)

The Data Rate limit may be set to 100Mbps, 300Mbps, 500Mbps, 700Mbps or 1000Mbps (up to the maximum licensed data rate). Traffic exceeding the rate set will be dropped according to the QoS priorities being used. The maximum Air Data Rate is set by Capacity Licence Key. If the Air Data Rate only shows 500 Mbps or 700 Mbps, and a higher capacity is desired, the please contact Fastback Networks Support to obtain a Capacity Licence Key. Please include the MAC addresses of both radio terminals, which will be needed to generate the Licence Keys. Note that on units fitted with AES capable hardware, if a valid AES Licence Key is applied, and AES encryption is activated, the modulation will be locked to QPSK mode only with a maximum throughput rate of 700Mbps. In this case, the AMOD setting options will not be displayed.

Figure 52 – IP Configuration (a) By default, management connectivity to a terminal is by fixed IPv4 address. The default IP address for an “A” terminal is 192.168.0.21 and the default IP address for a “B” terminal is 192.168.0.22. Changes to the IP address are protected by rollback which requires confirmation within expiry time limit, or else changes will be rolled-back. (b) If it is desired to set up a VLAN for management, this should be entered in the “Management VLAN Id” box with a value from 1 up to 4095, and by setting the “Management VLAN Priority” with a value from 0 to 7. Management VLAN priority may take values from 0 to 7, with 0 being lowest priority, and 7 being highest. “DEI” stands for “Drop Eligible Indicator” within IEEE 802.1Q. The option “DEI Enabled” sets the DEI Enabled bit, which indicates to other network devices (such as routers) that this VLAN has low priority, and in case of system overload, these frames may be dropped to reduce congestion. If a Management VLAN is entered, this will be enabled on pressing the “Apply” button: note that this is likely to result in loss of GUI connection to the terminal, and the PC or router will need to be reconfigured to use the same Management VLAN which has just been applied to the terminal. If VLAN Filtering is enabled on GUI page “VLAN Config”, then it is important to make sure that both terminals of the link are configured to use a VLAN for management, and this VLAN is listed in the “Allowed VLAN’s” table. (c) When DHCP is selected, the terminal’s IP Address, Subnet Mask and Default Gateway are acquired from a DHCP server. When DHCP is selected these fields are greyed out. When using DHCP the terminal cannot be managed until the DHCP client has started up and acquired an IP Address. 5.4.5.2 Administration Management – SNMP The SNMP Configuration Page is used to configure the SNMP Agent, see below.

Selection of SNMPv3 requires confirmation, otherwise the setting will be rolled back to its original value after the configured rollback timeout. Note that the SNMP agent is not enabled by default, and it must be enabled from this GUI webpage before it can accept SNMP messages. The settings which must be enabled on the GUI before using SNMP are as follows: 1. Webpage: “Admin/Management/SNMP” -> Enable SNMP v1/2c and Traps 2. Webpage: “Admin/Management/SNMP/SNMPv1/2c” -> Set Trap destination(s) 3. Webpage: “Admin/Unit” -> Enable SNMP Service 5.4.5.3 Administration - Management – SNMP – SNMPv1/2c Configure the SNMP v1/2c agent community strings and trap destinations.

Note: The IP address must be valid and reachable. - Community The trap community string sent in each trap to this destination, this is used by management systems that require authentication of the trap community. 5.4.5.4 Administration - Management – SNMP – SNMPv3 Configure the SNMP v3 agent supports User Based Model (USM) security. Note that the SNMPv3 configuration is only supported through the web GUI and the Sub10 Systems enterprise MIB. The configuration may be viewed but not changed via the standard SNMPv3 MIBs – this will be supported in a later release.

The real-time clock is used to timestamp events in logs and SNMP traps. Figure 57 - Setting the real-time clock manually The first option is simply to set the System Clock date and time, and press the “Apply” button in the “System Clock” section of the page. For greater accuracy the operator can synchronise the internal real time clock to an NTP (Network Time Protocol) time server. To enable the use of an NTP time server the operator must tick the “NTP Enabled” box, and also enter the IP address of an accessible NTP time server into the “Server 1” field (and also “Server 2” field if an alternative server is available), and then press the “Apply” button in the “NTP” section of the page.

The Alignment Voltage indication given is in volts and is the same voltage as can be measured with a voltmeter on the alignment port on the back of the terminal. Note that ATPC is always disabled when in “Alignment Mode”. After alignment is complete, replace the voltage port cap on the back enclosure of the terminal, and click on “Change” to return to Normal mode. The System Mode box displays “Normal” in GREEN. It is also possible to change mode by clicking on the “Change Mode” box on the Installation page. Once back in “Normal Mode”, ATPC will continue to operate if it was previously enabled on the “Radio Interface” page. Figure 59 - Installation - Alignment Mode
Liberator-V1000 User Manual Rev 04v05 Page 54 of 85 FBN Doc #: FBN-0125_04v05 Figure 60 - Installation – Normal Mode Note: In order to prevent false transitions into alignment mode due to the alignment cap not being correctly fitted and producing a false open-circuit, it is possible to use the GUI button “change mode” to force the unit from Alignment mode into Normal mode: in this case, the System Mode will display “Normal (Locked)” and removal of the alignment cap will not change back to Alignment mode, and there will not be any voltmeter reading available. The only way to unlock the mode to allow Alignment mode again, is to press the “Change Mode” button on the GUI again. Figure 61 - Home page showing System Mode in Alignment mode The Installation page also allows the Link Identifier to be set. The Link Identifier should be the same on both ends of the link, or else the link will not be established. In the case of a mismatch in Link Identifier, a warning message will be displayed.

It is possible to add new users by clicking on “New”, and this allows the new username, password and privilege level (“Role”) to be set. Note that the password must always be at least 6 characters long.
Liberator-V1000 User Manual Rev 04v05 Page 56 of 85 FBN Doc #: FBN-0125_04v05 Figure 64 - Security: Users Page A User’s role or password may be modified by clicking the “Modify” button. Please note that after following this process, it is necessary to logout and log back in to the terminal for the new privilege level (“role”) to take effect. So for example, if it is desired to elevate a User’s privilege level to “Maintenance” in order to allow the User to perform firmware upgrades, the User will not actually benefit from the change until they have logged-out and logged in again.

See Section 5.4.10 to apply the Licence Key, which will then make the “Encryption” option visible. In order to activate the AES encryption after the AES Licence Key has been applied (this procedure MUST be followed at both ends of the link, always update the REMOTE END FIRST): 1. In the “Encryption Algorithm” Drop-down box, select “AES-256”. 2. Enter a new AES 256 Encryption Key. This is a set of alphanumeric characters which MUST be the same at both ends of the link. The user may choose any set of characters they wish from (0 to 9) and (a to z). 3. Enter the same Encryption Key again in the second box to verify that it is correct. 4. Press “Apply” and the Encryption Key will now come into operation, and the data will be encrypted over the air in the transmit direction only.
Liberator-V1000 User Manual Rev 04v05 Page 58 of 85 FBN Doc #: FBN-0125_04v05 5. Reboot the unit and click “Confirm” to prevent Rollback to the unencrypted state. 6. Note that the link can then only be re-established if the remote terminal is also set with the same Encryption Key (this means that it is necessary to make this change on the remote end of the link FIRST). Notes: 1. If one terminal is reset to Factory Default, then its Licence Keys will be lost and AES encryption will be automatically de-activated, and this means that it will not be able to re-establish a link if the remote end is still running with AES encryption activated. In this case, it will be necessary to either de-activate the AES encryption on the remote end, or else to re-apply the AES Licence Key and re-activate the encryption on the end which had been reset to Factory Default. In this case it will be necessary to use the same AES 256 Encryption Key on both ends of the link. 2. The maximum capacity of the link when AES encryption is activated is 700Mbps full-duplex in the current software release. The AMOD settings on the radio page will not be displayed when AES encryption is activated. 3. A new encryption key will only be active after a reboot, and in this case always remember to click “Confirm” on each unit after reboot, to prevent automatic rollback to the previous state. Figure 68 - Enable AES-256 encryption, enter the desired encryption key (twice), and press Apply

The License Key is locked to the MAC address of the radio terminal, so the License Key can only be used on the radio terminal with the corresponding MAC address. Note that AES Licence Keys can be used only if the hardware version is AES capable. All Dual-port versions are hardware-capable of AES, but only certain Single-port versions are hardware-capable of AES. Please contact Fastback Network Support to obtain a License Key, the MAC addresses of both radio terminals will be required in order to generate the Licence Keys. Copy and Paste the License Key into the entry box, and press “Submit”. If there is an error message saying “Error: key not applied”, then it is likely that the MAC address is not correct, in this case double-check that the correct License Key has been applied to the radio terminal, and if the error message persists then please contact Fastback Networks Support. After a valid AES Licence Key has been correctly uploaded to a V1000 unit which has hardware capable of AES, then a new page “Encryption” will appear. This Encryption page is not visible until a valid AES Licence Key has been applied to the terminal. Note that the terminal will require a reboot before the entered Licence Key is activated.

Note that setting of these parameters should only be performed by a trained installer, as incorrect configuration may result in the link being dropped. SyncE mode may be configured as either:  None: This is the default setting, SyncE is disabled. This is the recommended setting unless a Primary Reference Clock input is available.  Provider: Use this setting if a Primary Reference Clock or other Synchronous Ethernet timing signal is available on the Ethernet port. Note that only one end of the link may be configured as SyncE “Provider”, and the remote end must be configured as “Consumer” in this case.
Liberator-V1000 User Manual Rev 04v05 Page 61 of 85 FBN Doc #: FBN-0125_04v05  Consumer: Use this setting if the remote end of the link is to be configured as “Provider”. Note that only one end of the link may be configured as SyncE “Consumer”. Figure 72 - Timing Configuration Page (SyncE and 1588) On the Dual-port version, it is necessary to choose the timing source port if Provider is selected (Primary or Secondary port for the Provider). On the Dual-port version only, IEEE1588 mode may be configured as either:  None (1588 not active)  Transparent (1588v2 Transparent Clock, requiring that one end of the link must be configured with SyncE setting as “Consumer”). 5.4.12 Administration - Unit

Always press “Apply” so that changes will take effect. The SNMP Service box must also be ticked on this page, in order to allow use of SNMP. Figure 73 - Setting the Rollback function Figure 74 - Icon Displayed When Rollback Is Enabled and a Critical Change Is Made on the GUI, showing timer countdown 5.4.13 Administration - Alarms The unit has a number of default alarms which cannot be removed from the display (but can be disabled), and in addition the user can specify extra alarms: these can be added on the “Alarm Management” page, but they only take effect after pressing the “Apply” button. For each alarm, the type and severity can be changed, and there is also an option for sending a trap to SNMP and/or to Syslog. The “Alarm Management” page allows the user to create and configure alarms, see below.
Liberator-V1000 User Manual Rev 04v05 Page 63 of 85 FBN Doc #: FBN-0125_04v05 Figure 75 - Alarm Management An alarm is based on the monitoring and comparison of a measured object with configured thresholds. An alarm is persistent in that it can exist in a raised state until it is later cleared. The attributes of an alarm for example the action taken, frequency of monitoring and values of thresholds are fully configurable. The unit has a number of fixed alarms by default. The attributes of a fixed alarm can be configured except for the name and the monitored object; a fixed alarm cannot be deleted. In addition to fixed alarms the user can create user defined alarms. A user defined alarm is fully configurable including the name and measured object. 5.4.13.1 Alarm Names, Measurements and Notifications - Configure alarm attributes. • Alarm Name – Identifies the alarm (cannot change fixed alarm names) • Enable Alarm  Enabled Measured object is monitored and alarm state will be raised or cleared according to configured thresholds  Disabled Measured object is not monitored, and alarm state is unknown • Measured Object The parameter in the unit subject to monitoring and threshold comparison • Alarm State Colour coded state showing severity for raised alarms • Alarm Type Defines the type of alarm Unit, Radio or Ethernet and defines type of SNMP trap sent • Alarm Severity The severity indicates the importance of the alarm • Measured Object The parameter in the unit subject to monitoring and threshold comparison • SNMP An SNMP trap is sent when alarm state changes • SysLog A line of Syslog is written when alarm state changes • Delete Delete the alarm (only user defined alarms can be deleted) A user-defined alarm can be added by selecting the name of the alarm and the measured object. The following example adds a user defined alarm to monitor the previous 15m average Radio Rx Power.
Liberator-V1000 User Manual Rev 04v05 Page 64 of 85 FBN Doc #: FBN-0125_04v05 Figure 76 - Add User Defined Alarm The new alarm is added to the Alarm Management table allowing alarm attribute configuration, note that monitoring interval and thresholds must be configured using the ‘Alarm Threshold Management’ GUI. IMPORTANT: Before enabling the alarm it is recommended that the user configures the monitoring interval and threshold crossing attributes, because otherwise initial alarms may be raised and/or cleared using the default monitoring interval and threshold values, and this could result in initial spurious and incorrect alarm states. See ‘Threshold Management’ for configuration. Alarm Management with a new alarm added to the table. Figure 77 - New Alarm Configure Attributes Please also note that ‘Alarm Type’ configuration selects the type of SNMP notification sent when the alarm state changes. For further alarm behaviour configuration select ‘Threshold Management’. The alarms page: “Threshold Management” allows the user to configure monitoring intervals and threshold crossing behaviour. Each alarm is listed as in ‘Alarm Management’. The user is able to configure the behaviour of each alarm, see below.

There are 2 memory banks. The firmware upgrade process will upload the new firmware to the INACTIVE memory bank. Therefore, before
Liberator-V1000 User Manual Rev 04v05 Page 66 of 85 FBN Doc #: FBN-0125_04v05 performing a firmware upload, first be sure that a stable firmware version is in the ACTIVE memory bank. Click on the “Change” button in the “Switch bank” section to swap the active and inactive banks if necessary. The “Copy” button in the “Duplicate bank” section allows a firmware version to be copied into both banks if desired. Firmware upload uses HTTP, simply choose the filename and press “Upload”. There is also the option to upload a firmware file using a TFTP server: in this case it is necessary to set-up a TFTP server, and then select the server IP address and filename. Figure 79 - Firmware Upgrade page Once initiated the firmware upgrade process should not be interrupted. Interrupting the process could result in a corrupt firmware image and a non-operational radio terminal.

Upon the next reboot and login the confirm / rollback option will appear. If the bank change is not confirmed within the rollback expiry time after reboot (default 3 minutes), then the rollback function will rollback the change made to the Firmware bank which will cause the unit to reboot back to the original bank – this is a failsafe mechanism to protect the radio link in case the link does not re-establish after the Firmware bank change has been made.

If a configuration confirmation is not received within a timeout period the configuration is rolled back to the previous values. Rollbacks can be enabled or disabled and the rollback timeout can be configured using the Administration->Unit web GUI, see section 5.4.10. The confirmation/Rollback feature operates on configuration whether being changed from the Web GUI or over SNMP. The table below lists all the configuration that requires a confirmation. If confirmation or rollback is not provided either via the GUI or via SNMP it will be reset to the previous values after the configured timeout. Confirmation or Rollback over SNMP is achieved by setting the MIB object ‘sub10UnitMgmtTransaction’. The transaction status can be read by getting the MIB object ‘sub10UnitMgmtTransactionStatus’ (See Sub10 Systems enterprise MIB for more details).

The settings which must be enabled on the GUI before using SNMP are as follows: Webpage: “Admin/Management/SNMP” -> Enable SNMP v1/2c and Traps Webpage: “Admin/Management/SNMP/SNMPv1/2c” -> Set Trap destination(s) Webpage: “Admin/Unit” -> Enable SNMP Service The SNMP Agent is compatible with SNMPv1 and SNMPv2c. The SNMP Configuration is as follows: • Enable Agent The agent will respond to SNMP v1/2c requests GET/SET/GET-NEXT and GET-BULK • Enable Traps The agent will send traps to the configured trap destinations. • Trap Destinations Up to three destination are possible, each requiring: • IPv4 Address A valid IP address of the receiving management system. Note: The IP address must be valid and reachable. • Community The community string sent in each trap to this destination, this is used by management systems that require authentication using the trap community string. • Communities SNMPv1/v2c community strings for read-only and read-write operations when accessing MIB object via an SNMP management system. • Read Community The community string used for read access • Write Community The community string used for write access The following MIBs should be loaded into communicating network management tools: Table 4 - V1000 MIB Compliance Table MIB Module Usage RFC1213-MIB MIB-II Standard MIB-II IF-MIB ifMIB For SNMPv2c linkUp, linkDown notifications only interfaces supported as part of MIB-II.

Liberator-V1000 User Manual Appendix A – Technical Information Page 78 of 85 FBN Doc #: FBN-0125_04v05 Appendix A - Technical Information A 1. Troubleshooting This chapter provides solutions to problems that can occur during the installation and operation of the Liberator-V1000. It covers various aspects of installation and network setup. Note: Each of the following points must be checked at both ends of the link. Start by running the entire procedure on one side (e.g. Terminal A). If this does not solve the problem, repeat all the steps at the opposite terminal. 1.1. Power and Network Connection You must verify that the terminal is connected to the power. The PoE injector must be installed and plugged in. Go to the terminal, disconnect the RJ-45 connector and verify if there is power in the cable using a PoE++ tester. WARNING: It is strongly advised that the mains power supply should be disconnected before making or breaking the CAT5e drop-cable connection between the PoE++ supply and the radio terminal (Outdoor Unit). If it is not possible to disconnect the mains power before making or breaking the CAT5e drop-cable connection between PoE++ and radio terminal, then ALWAYS first disconnect any network cable attached to the “IN” port of the PoE++ supply. Take the network cable and plug it into a notebook or a network testing device and verify that there is a valid network connection. If there is any problem, please replace the cable and validate the connection again. 1.2. Network Configuration Check that the PC’s IP address is in the same range and subnet as the Liberator-V1000. Note: The default IP address of the Liberator-V1000 is 192.168.0.21 and 192.168.0.22 for terminal A and B respectively. All terminals on the network must have a unique IP address in the same range, e.g. 192.168.0.X. Any terminal with identical IP addresses will not be visible on the network. They must all also have the same subnet mask (e.g. 255.255.255.0). Ping the terminal to make sure that the Liberator-V1000 is responding. On a Windows PC, go to Start → Run → Type “Command” → Type “ping 192.168.0.21/22”. A successful ping will generate four replies. As soon as the network configuration is correct you can access the GUI (Graphical User Interface) and check the settings according to the section titled “Factory-Defaulting a Terminal”. If a Management VLAN is enabled, then it will be necessary to set-up the communicating PC / laptop / network device with the same VLAN ID, in order to communicate with the V1000 management agent. 1.3. Misalignment On the Installation screen you see the signal strength in dBm (e.g. -30 dBm). The correct RSSI value can be obtained from the Sub10 Systems Link Availability Calculator. If the value is more than 5dB below below the Link Availability Calculator value, then the antenna is not properly aligned to receive the signal. You therefore need to re-align the terminal to its opposite terminal (please follow the instructions in the section titled “Antenna Alignment”). 1.4. Mixed radio terminals It is not possible to mix Single-port and Dual-port terminals. 1.5. Encryption settings If AES encryption is used, then it must be enabled on both ends of the link, and the same encryption key used on both ends, or else no data will pass over the link.
