40 Installation TB7300 Installation and Operation Manual© Tait Limited November 20175.1.3 Equipment VentilationAlways ensure there is adequate ventilation around the base station (refer to “Cabinet and Rack Ventilation” on page 40).Notice Do not operate equipment in a sealed cabinet. The ambient temperature must stay within the specified range. We recommend strongly that you ensure the cooling airflow is not restricted.Notice The cooling fans are mounted behind the front panel. To ensure adequate airflow through the base station, do not operate it for more than a few minutes with the fans disconnected (such as when the base station is being serviced).5.1.4 Ambient Temperature SensorThe ambient temperature reading for the base station is provided by the temperature sensor located inside the chassis.5.1.5 Cabinet and Rack VentilationThe cooling airflow for the subrack enters through the front panel and exits at the rear. For optimum thermal performance, the heated air that passes through a base station must never be allowed to re-enter the air-intakes on the front panel. Any space at the front of the cabinet not occupied by equipment should be covered by a blanking panel. See Figure 5.1 on page 41.Equipment installation should observe the following guidelines:■The recommended maximum number of subracks in a 38U cabinet is five, as illustrated in Figure 5.1 on page 41.■Any space at the front of the cabinet not occupied by equipment should be covered by a blanking panel. Refer to Figure 5.1 on page 41.■Subrack placement in the cabinet should include a 2U gap at the top of the cabinet.■To allow enough cooling airflow through a cabinet-mounted base station, the cabinet should allow for 50 cu.ft/min for each subrack (0.024 cu.m/s).■To ensure adequate ventilation, the cabinet should have a vent at the top with an area of approximately 23in² (150cm²) per subrack, or a similar area of ventilation at the rear of the cabinet behind each subrack.■The maximum ambient temperature at the base station front panels must not exceed +140°F (+60°C).

44 Installation TB7300 Installation and Operation Manual© Tait Limited November 20175.4 Initial Setting UpBefore putting the base station into service, you may want to carry out some basic functional testing, configuration, and tuning (if required). This section provides an overview of these procedures:■checking that the base station powers up correctly■checking the basic functionality of the base station by using the tests available in the web interface■customizing the configuration for the intended installation and verifying that the configuration is correct■changing the root password■tuning the base station, if required5.4.1 Confirming OperationNotice The RF output must be connected to a suitable attenuator or dummy load. Do not remove the load while the PA is transmitting as this may damage the PA output stage.Applying Power 1. Apply power to the TB7300.2. Check that the base station powers up correctly:All LEDs turn on initially, then the transmit and receive LEDs turn off, leaving the green power LED on, and the red alarm LED flash-ing. The alarm LED will turn off when the base station has finished its start-up sequence.Functional Tests The following table provides an overview of the tests available using the web interface. Refer to the base station Help for full details of these tests.Test Notes Menureceiver operation requires a suitable RF source Diagnose > RF Interface > Receivertransmitter operation requires connection to the networkDiagnose > RF Interface > Transmitterping checks the IP connection to another device with an IP addressDiagnose > Connection > NetworkNTP query checks if the NTP-based time synchronization is working
TB7300 Installation and Operation Manual Installation 45© Tait Limited November 20175.4.2 Working with ConfigurationsThe Web UI page Tools > Files > Configuration allows you to manage your base station configuration.You can:■Back up a configuration. This stores a snapshot of the base station’s current configuration. It is advisable to back up the current configuration before making significant configuration changes.■Upload a configuration. This copies a configuration from your computer to the base station. You can develop a master configuration and upload it to all the base stations in the network.■Restore a configuration. This activates the selected configuration after making it compatible with the current software. You can restore configurations that have been backed up on the base station.■Download a configuration. This copies the selected configuration to your computer so that you can store it.5.4.3 Customizing the ConfigurationThe following steps provide an overview of the process used to configure the base station with the settings it needs. Refer to the Help for detailed information.1. Log in to the base station (refer to “Connecting Your PC to the Base Station” on page 24 for more details).2. Select ‘Configure.’ The base station has many different settings that can be configured before it is put into operation, such as:■channel configurations■alarm control and SNMP agent■network interfaces■quality of service■CWID■miscellaneous items such as NTP and package servers3. Make the changes needed in each form and click, ‘Save.’ All changes made in the form will only be applied when the form is saved.Notice Before making changes, you should save the configuration to your PC or network; this provides a baseline which can be restored to the base station if the configuration information becomes lost or cor-rupted. You should also back up the configuration before downgrading to a dif-ferent software release. Note that if you downgrade and then upgrade software, configuration values for new features may reset to default.
46 Installation TB7300 Installation and Operation Manual© Tait Limited November 20175.4.4 Restricted Port NumbersCertain configuration settings in the base station’s web interface require you to enter a port number (for example, the trunking interface).Two ranges of port numbers are unavailable for use with the base station. The web interface will prevent you from entering a number from these ranges, as explained below.5.4.5 Changing the Root PasswordNotice The following procedure can be carried out only if secure shell access (SSH) is enabled. Secure shell access to the base station is disabled by default from version 1.35 onwards. To enable SSH, select Tools > Settings > Secure shell and click ‘Start’.The root password to the Linux operating system of the base station is a possible security risk. The equipment is delivered with a default password that is well known. Knowledge of the password could be used to render the equipment inoperable, for example, by deleting files. If you are concerned about the security risk that this poses, change the password. If Tait provides support services, they will likely need to know the password.Notice If you change the password and then lose it, the equipment must be returned to Tait. Make sure that you store the password securely and do not lose it.To change the root password, follow these steps.1. Log in from your PC to the base station using SSH client software such as PuTTY. The username is root and the default password is k1w1. 2. At the # prompt, enter the command passwd.3. Follow the on-screen instructions.4. Record the password in a secure location.Tait networks are deployed with default weak passwords. For the sake of security, Tait strongly recommends changing the default password where applicable.Restricted Port Numbers Details0 – 1023 The “well-known ports”, commonly used by other devices in a network. Using a port number in this range could cause compatibility problems with other devices.12000 – 14999 Reserved for internal use in the base station. Using a port number in this range could cause the base station to malfunction.
TB7300 Installation and Operation Manual Installation 47© Tait Limited November 20175.4.6 Tuning the ReceiverBefore the base station is installed on site, you may need to tune the receiver front end. The receiver front end requires tuning if the receive frequency is shifted more than 2MHz away from the previously set frequency, or the RSSI level of the new frequency is more than 1dB lower than the RSSI level of the previously set frequency. Manual tuning is not required for the H5 (400MHz to 470MHz) model.The receiver in the B-band base station covers one of the following frequency bands, depending on the model:■B3 - 148 to 174MHzEach of these bands is split into 2 sub-bands:■B3 - 148 to 159MHz and 159 to 174MHzEach sub-band has its own helical filter (shown in Figure 5.2 below) which is electronically switched in or out of circuit depending on the frequency programmed into the base station. The bandwidth of these helical filters is approximately ±1.5MHz.Figure 5.2 Identifying the B-band receiver front end helical filtersB3: 148 to 159MHzB3: 159 to 174MHz
48 Installation TB7300 Installation and Operation Manual© Tait Limited November 2017To check the RSSI level and tune the receiver front end (if required), follow these steps:1. Place the base station on its side or upside down to allow access to the holes on the base to tune the helical filters.2. Log in to the TB7300 and select Monitor > Interfaces > RF Interface. For information on connecting directly to the base station, refer to “Connecting a Networked PC to a Base Station” on page 25.3. Feed a signal at the currently tuned receive frequency and at a level of –80dBm into the RF input. Check that the RSSI reading on the RF Interface page is –80dBm ±1dB.4. Set the TB7300 to the new receive frequency.5. Change the RF input signal to the new receive frequency at –80dBm. Check that the RSSI reading is –80dBm ±1dB. If it is, the receiver front end does not require tuning. If it is not, go to the next step.6. Using the Johanson tuning tool1, adjust the correct helical filter for the new frequency (as shown in Figure 5.2) to obtain a peak RSSI reading. This reading should be within 1dB of the reading at the previous frequency.Adjust the center resonator of the filter first, followed by the two outer resonators (in any order). Each resonator should require approximately the same amount of adjustment when tuning.A change in frequency of 5MHz requires approximately one turn of the tuning slug. If tuning to a lower frequency, turn the slug clockwise; for a higher frequency, turn the slug anti-clockwise.7. Change the RF input signal and the receive frequency to 0.5MHz above and below the required frequency and check that the RSSI reading does not drop by more than 0.5dB from the reading at the required frequency.8. Recalibrate the RSSI at the new frequency (Calibrate > Calibrate > RSSI).If you wish to confirm the accuracy of the tuning procedure, carry out a sensitivity measurement at the new frequency.1.

TB7300 Installation and Operation Manual Installation 49© Tait Limited November 20175.5 Installing the Base Station on Site5.5.1 Base Stations for Trunked SystemsWhen installing base stations that are part of a trunked system, it is important to observe good site engineering rules. This is especially true when the channels are combined into a single antenna.If possible, the RF planner should avoid frequency plans in which the Rx to Tx spacing is an exact multiple of the trunked channel spacing, thus forcing Tx intermodulation products to fall outside the Rx channels.Cables and antennas should be of high quality. Solid shield heliax cables are best, but if braided shield cables must be used for short distances, their braids must be silver-plated. Isolators must be used at all transmitter outputs.When the outputs of more than one transmitter are combined, their voltages add, and the resulting peak envelope power is not simply the sum of their powers, but is equal to the power of one of them multiplied by the square of the number of sources. Cables, components, and hardware must be rated to withstand the peak envelope power.During the commissioning process, all transmitters should be activated together using a diagnostic test tone, while the receiver RSSI is monitored. There should be no discernible increase in RSSI while the transmitters are active.5.5.2 Equipment RequiredIt is beyond the scope of this manual to list every tool that an installation technician should carry. However, the following tools are specifically required for installing the base station:■Philips #2 tip screwdriver used to connect the DC power cables to the DC power terminals■Pozidriv PZ3 screwdriver for the M6 screws used to secure the tray to the cabinet in Tait factory-assembled systems■8mm spanner for the M5 nut on the ground connectorYou can also obtain the TBA0ST2 tool kit from your regional Tait office. It contains the basic tools needed to install, tune, and service the base station.
50 Installation TB7300 Installation and Operation Manual© Tait Limited November 20175.5.3 Mounting the Base Station1. Fit the base station into the cabinet or rack and secure it firmly with an M6 (or 0.25in if using the imperial system) screw, flat and spring washer in each of the four main mounting holes b, as shown in Figure 5.3 on page 50.2. The base station can be wall-mounted by rotating the front mounting brackets and fitting the optional rear brackets (TBBA03-01). When the base station is wall-mounted ensure the airflow is from bottom to top (front panel mounted down) or side to side.3. For transport or in installations subject to vibration, the base station should be supported at the rear using a transit bracket (Tait recommends using the TBBA03-04 transit bracket).Cabling Tait recommends you route all cables to and from the base station along the side of the cabinet so the cooling airflow is not restricted.Cables should be well supported so that the connectors or terminals on the base station and on the ends of the cables do not have to support the full weight of the cables.Cables must be routed so that they do not restrict the air outlets at the rear of the base station.Figure 5.3 Base station mounting pointsbmain mounting holes eground pointcbase station frack framedDC power connectorfEcbD

52 Installation TB7300 Installation and Operation Manual© Tait Limited November 20175.6.2 Connecting DC PowerThe base station is designed to accept a nominal 13.8V DC, with negative ground.Notice Any mains power supply used to power the base station is required to meet the isolation separation for reinforced insulation of 3000Vrms or 4242VDC.The DC power connector at the rear of the base station is a heavy-duty M4 screw terminal connector suitable for many forms of connection.You must connect the DC supply from the battery to the base station via a readily accessible disconnect device such as a fuse or DC-rated circuit breaker with the appropriate rating, as shown in the table below.The DC input leads should be of a suitable gauge to ensure less than 0.2V drop at maximum load over the required length of lead. Use only flexible copper cables.Terminate the DC input leads with a suitable crimp connector for attaching to the M4 screws of the DC power connector.Pin Signal Name Signal Type Notes External View1 ground input The maximum current for each band:■B band: 50W 9.6A Typical■H band: 40W 8.1A Typical2 13.8VDC inputNominal Supply VoltageInput Voltage RangeCircuit Breaker/Fuse RatingRecommended Wire Gaugeaa.

TB7300 Installation and Operation Manual Installation 53© Tait Limited November 20175.6.3 Connecting RFNotice Do not remove the load from the base station while it is trans-mitting as this may damage the PA output stage. Before disconnecting RF cables, put the base station into ‘Offline’ mode to prevent any trans-missions.The RF input to the base station is via the marked BNC connector on the rear panel. The RF output is via the N-type connector on the rear panel (refer to Figure 5.4 on page 51).Cables and antennas should be of high quality. Solid shield heliax type cables are best, but if braided shield cables must be used for short distances, their braids must be silver-plated.Recommendations for Installing the Base StationWe recommend the following installation procedures, which should protect the PA from damage under all but the most extreme operating conditions1. Do not connect the base station directly to the antenna. Fit an isola-tor or duplexer between the base station and the load. Fit the isolator as close as possible to the RF output connector on the base station. Do not connect any switching equipment between the isolator and the base station, unless the switch cannot operate while there is RF present (i.e. the base station is transmitting).2. Fit a surge suppressor to the antenna cabling where it enters the building.3. Inspect all cables and equipment connected to the base station for defects.A broken antenna or ice is unlikely to cause damage to the PA.Explanation The circuit design of the PA protects the circuitry from high VSWR. This makes it difficult to damage the RF power device by keying the PA into a mismatched load, or if the load deteriorates over even a short period of time (milliseconds).However, it is possible to damage the device if all the following conditions happen at the same time:■there is a step change in the PA load (for example, the load is removed)■the PA is transmitting■the feed line loss between the PA and the mismatch is <1dBThe effect of such conditions is variable: some devices will not be destroyed, and some may fail after repeated load interruptions.
54 Installation TB7300 Installation and Operation Manual© Tait Limited November 20175.6.4 Connecting an External Frequency ReferenceAn external reference frequency is not normally required for B band. However, an external reference can be used when you need to maximize the range of the base station. The external reference frequency can be 10MHz or 12.8MHz, with an input level of 300mVpp to 5Vpp. The stability of this reference should be better than 100 parts per billion. The base station automatically detects the frequency of the external reference and configures itself accordingly.If an external reference is required, enable the external reference “external reference absent” alarm (Configure > Alarms > Control).Use a 50: coaxial cable (RG58 or RG223) to connect the external reference to the base station’s external reference frequency input. You can daisy-chain up to eight base stations using T-junctions. The maximum overall cable length is 30m. Terminate the last connection (including single base stations) with a 50: load.Figure 5.5 Daisy-chaining an external frequency reference inputmaximum of eight base station loads on one frequency reference outputmaximum overall cable length is 30m50: termination
TB7300 Installation and Operation Manual Installation 55© Tait Limited November 20175.6.5 Connecting a 1PPS SourceA 1PPS signal is required for simulcast base stations. Use a 50ȍ coaxial cable (RG58 or RG223) to connect the source to the base station’s 1PPS input. You can daisy-chain up to eight base stations using T-junctions. We recommend that the cable length between the first and last load is kept to a minimum. This will reduce any propagation variation between base stations. The maximum overall cable length is 30m. Terminate the last connection with a 50ȍ resistor, otherwise reflections of the 1PPS pulse may occur.Notice If 1PPS is used, then 1PPS and NTP must both be derived from the same time base. Normally this will be a GPS disciplined source.Figure 5.6 Daisy-chaining a 1PPS input50: terminationThe longest length of cable must be between the source and the first base stationUse short lengths of cable between each base stationMaximum of eight base station loads on one 1PPS output
56 Installation TB7300 Installation and Operation Manual© Tait Limited November 20175.6.6 Ethernet ConnectionThe RJ-45 socket on the reciter’s rear panel provides the 10 BASE-T or 100 BASE-T Ethernet connection to the other devices in the network. Use a Cat-5 cable to connect this socket to the Tait Network via a router or switch.The Web UI allows you to set the Ethernet port speed auto-negotiation to 10/100 Mbit/s or to negotiate a maximum 10 Mbit/s. Tait recommends that you keep the port speed at the factory default setting of 10 Mbit/s. The reciter hardware and software are scaled to meet the performance requirements of processing multiple voice streams along with supervisory control and management communications. 10 Mbit/s is ample for those requirements. The 10/100 Mbit/s setting is provided for compatibility reasons, but it is possible under high traffic conditions at 100 Mbit/s for traffic arriving at the reciter at the full rate within a small timing window to overflow internal buffers and therefore suffer packet loss. If you set the port speed to 100 Mbit/s and observe QoS lost packet alarms, then review your Ethernet port speed settings.With the port speed at 10 Mbit/s it is particularly important to set the voice QoS on the reciter port of your site router or switch to a strict priority queue policy - which is the same policy that you should also be setting for your site link ports. The default QoS settings restrict the voice bandwidth to 1/25th of the port speed which is smaller than the required bandwidth for typical systems at 10 Mbit/s.If necessary, refer to “Ethernet Connector” on page 60 for a list of Ethernet connection pin allocations.
