2 Quick start electricity/safety competence and who is familiar with Before proceeding with the installation, verify that the equipment works on the ground. Power up both units and put them between your computer and network access, you should have full communication within a few minutes of powering up the units. (If the units have no internal antenna make sure you place the antenna connectors directly opposite each other.) Both the units are pre-configured in Master mode with the same IP address, user name and password: IP address Username Password admin public Log in to the units one by one and configure them in Master and Client mode so they connect to each other. Installing the link Mount the first unit and point it towards the site of the second unit. Power it up and make sure the Power LED is lit and the status LED blinks slowly. Mount the second unit. Power it up and adjust it for best signal using the status LED see section 1.9 for details.

3 Adjust the first unit for best signal using the Status LED.

4 Trinity-300 Series Make sure all cables are secured and connect the link to the network. Configure the distance parameters at the master unit to reflect the correct distance between the units. Note Make sure that the polarization on both units is the same. Unaligned polarization will significantly reduce the signal strength. For more information about antenna polarization and how to successfully tune the links for good performance, refer to Repeatits Deployment Guideline document. 2

7 Installation Guide 1.1 Who should use this guide Installing fixed outdoor radio links requires technical expertise and should only be carried out by a trained technician. You should only attempt to install and configure the Trinity link if you have Experience in mounting outdoor radio equipment and aligning antennas. Understanding, or common knowledge, about network equipment. Made sure that the installation site is suitable and complies with local radio, electrical and safety regulations. 1.2 Additional tools required Depending on the conditions at the installation site other tools might be needed, including, but not limited to Cat5E Ethernet cable RJ-45 crimp tool and RJ-45 connectors if not using a pre-assembled Ethernet cable An adjustable wrench

8 Drill for wall mounting Ground cables Cable ties to secure cabling

9 1.3 Unit description There are three LEDs on the units: power, status and Ethernet link/activity. LED Colour Status Description Power (P) Status (S) Green Green On Flashing Power on Signal strength pattern Blinking Firmware upgrade in progress Ethernet (E) Green On/blinking Reflects Ethernet traffic and link status Off No Ethernet link 1.4 Installation Installing a Trinity-300 system consists of the steps outlined below. Each step is explained more thoroughly in the following sections. The Trinity-300 system consists of two Trinity-300 units, one master unit and one client unit, the installation steps needs to be carried out for both units. 1. Before taking the units to the site, configure one of them to be the Master and the other one to be the Client. Normally this is done in an office environment. Note that link throughput can be degraded by multipath effects and other RF related phenomenon in an office. Therefore, just make sure that the links connect to each other and have proper IP settings before taking them to the site. 2. Mount the Trinity-300 unit and antenna (if applicable) at site A. 3. Install the PoE at an indoor location where power and network equipment is available. 4. Run Ethernet cable from the PoE to the mounted Trinity-300 unit. 5. Repeat the above steps for the unit at site B. 6. Align antennas for best signal reception. For longer distances, this normally requires re-alignment of antennas on both sides of the link. 7. For optimal link throughput the following parameters must be

10 updated in the web interface Distance - should accurately reflect the distance in kilometers between the units.

11 1.5 Mounting a Trinity-300 unit A Trinity-300 unit should preferably be mounted in location that allows the unit to be placed high above interfering objects like buildings and trees. Radio masts often provide the best mounting conditions, but when mounting radio equipment with other wireless systems in the vicinity you should always be careful as sufficient isolation between your antenna and other antennas/equipment has to be secured. If it is not possible to mount the equipment in a mast, it could also be mounted on roof tops, walls etc. Note The Trinity units should be mounted with their antennas having a clear line of sight and free Fresnel Zones between them! For more reading on this topic, please refer to Repeatits Deployment Guideline. Observe the antenna polarization and make sure they match at both installation sites. If the sites are configured with different polarizations, the link will be subject to strong signal degradation. Use the supplied mounting kit to securely mount the units at both locations, make sure the mounting brackets are connected to ground. Tip Do not tightly secure the unit and/or antenna until the antenna alignment process in complete.

12 Mounting instruction for Trinity-323 and Trinity-318 See the supplied document for detailed mounting instructions. Figure 1 - Trinity-323 and Trinity-318 pole mounting Mounting instruction for Trinity-300 The Trinity-300 is supplied with mounting brackets for pole mounting. 1. Run the pole clamps around the mounting pole. 2. Run the pole clamps through the mounting brackets. 3. Attach the pole clamps to the unit using the supplied screws. RJ-45 connector assembly for Trinity-300 Series The connector casing is delivered assembled, unscrew the connector (you do not need to remove the gasket (4)). 1. Unscrew the sealing cap from the connector. 2. Gently pull out the seal. 3. Pull the cable through the sealing cap. 4. Insert the RJ45 cable and make sure it is fully inserted into the connector. 5. Put the seal around the cable and push it into the connector. 6. Fasten the sealing cap to the connector and tighten.

13 1.6 Ethernet cabling Run Cat5E Ethernet cable from the location where the PoE is to be installed to the location of the Trinity-300 unit, allow for some slack on the wire to avoid putting extra strain on the Ethernet connectors. Make sure the Ethernet cable you are using is rated for outdoor use to avoid decreased cable life time. RJ-45 pin-out If you are not using a pre-assembled Ethernet cable, apply the RJ- 45 connectors on to the both ends of the cable using the pin-out table and diagram below. PoE Wire Colour Function RJ-45 1 Twisted pair White/Green Ethernet (RxN) 1 2 Twisted pair Green RxT 2 3 Twisted pair White/Orange Ethernet (TxT) 3 4 Twisted pair Orange Ethernet (TxN) 6 5 Twisted pair Blue Power (+) 4 6 Twisted pair White/Blue Power (+) 5 7 Twisted pair White/Brown Power (-) 7 8 Twisted pair Brown Power (-) Installing the power supply Install the supplied PoE indoor where power and other network equipment is available. The PoE can be located at most 100 meters from the unit. Note The supplied PoE-adapter (Power-over-Ethernet) is strictly for indoor use only!

14 Tip Make a loop on the Ethernet cable indoors near the PoE to allow water to drain more easily from the cable, before reaching the PoEs unprotected Ethernet connector! Connect the PoE port marked P+DATA OUT to the Trinity-300 unit using an outdoor-rated Cat5E Ethernet cable. The PoE port marked DATA IN should be connected to user supplied network equipment such as a switch or router. Note The Trinity-300 unit will boot as soon as the Ethernet cable from the PoE is connected! 1.8 Finalizing the installation Once both units are mounted they need to be aligned for proper operation. The Trinity-300 system assists you in doing this using external visual signals and a web interface that shows detailed information about the link status and its signal strength. Configuration The Trinity-300 units come with default settings and need to be configured before connecting to each other. For optimal throughput you are recommended to accurately configure the distance between the units using the web interface on the master unit. You should also modify the IP-configuration on both units to reflect your network setup. Alignment Make sure the units are roughly aligned using visual sight or a compass before proceeding with this step. On site A (or B), slowly move the antenna towards site B (or A). Use one of the alignment tools to find the optimal alignment. External visual indication The LED (if enabled) indicates the current signal strength with a set of pulses followed by a short pause. Note The alignment LED is enabled by default.

15 Pulses from dbm to dbm 1 pulse pulses pulses pulses pulses pulses 30 Web interface The web interface contains status indicators for both link status and signal strength. Color Green Yellow/green Orange Red Status Very good signal strength Good signal strength Bad signal strength No link Securing the installation When the Trinity-300 link is running and the antennas have been properly aligned the units must be secured in place to avoid the units moving due to strong winds. If the units become misaligned the link might be lost. Tightly fasten the mounting brackets to secure the unit in place and make sure the brackets and chassis are connected to ground. Secure Ethernet and antenna cabling using cable ties to avoid unnecessary wear on the cabling material and connectors.

16 Configuration The Trinity-300 series units can be configured via a web interface built-in to the unit or by using the Repeatit network management system, Radio Configuration Software (RCS). 2.1 Trinity-300 series Configuration concepts The Trinity-300 series features an advanced configuration management system with the ability to roll back to previously working settings, even with automatic rollback in case of link loss. This allows you to try out different settings to optimize your link throughput while minimizing the risk of a disconnected link. Configuration areas A Trinity-300 series unit has several so-called configuration areas. These areas hold configuration data and each area contains one unique configuration instance. Some areas contain different data depending on the unit status whilst some only contain static configuration data that never change. The following different areas exists within a Trinity-300 series system Inactive area When you modify the configuration via the web interface, all changes end up in this area. This is only a place holder until you choose to apply the new configuration. Until that time, you can rollback and/or keep modifying any setting without disrupting the unit or link status. Active area This area always contains the current settings in use by the unit. Stored area Contains the configuration currently written to flash, this might differ from both the inactive and active configurations.

17 Factory defaults Static bare basic configuration. Note The factory default IP address is , the default username is admin and default password is public. 2.2 Configuring using the Trinity-300 series web interface Both units in your Trinity-300 series link can be fully configured using the built-in web interface. The following section will guide you through how to use the interface to modify the link configuration, please refer to section 2.3 for details on the available configuration parameters. Figure 2 Configuration view. All configuration options in the Trinity-300 series can be found under the tab marked Configuration in the web interface. This tab is shown below.

18 Figure 3 - Configuration tab with highlighted fields. Short description on these three fields: 1. Configuration management pane. Anything related to apply, save or load of configuration changes is handled here. 2. View selector. By changing between Radio settings, Network settings, QoS settings and System settings, the information in the configuration pane is changed to allow you to reach the corresponding settings. 3. Configuration pane. The sections below describe these fields and how to make configuration changes in each one. Next to most parameters you find a small question mark. Click on one of those to get information about the parameter.

19 Figure 4 - Click the question mark next to a parameter to see a description of the parameter and selectable parameter values. This example shows the Mode of the unit. How to make configuration changes To make configuration changes successfully, follow the steps that are summarized in the figure and the steps below. Figure 5 - How to change parameter settings and make them permanent. 1. Select parameter to change. Note that if you attempt to set an invalid value, such as a too large distance value or an invalid IP address, the configuration modification will fail and the field containing invalid data is highlighted in red. 2. Select the new value. For example, the regulatory domain is changed from France to Finland. 3. Click the Set button at the bottom of the page. This should result in France popping up to the right in brackets (still the valid configuration). Finland is stored in the unit s inactive configuration area. See figure below. Figure 6 - "Finland" is in the inactive configuration area after the Set

20 button is clicked. "Egypt" is still the valid configuration. A reboot would completely remove the Finland value at this stage. 4. When Set was clicked, the configuration pane to the left should also have been populated with an Apply button and an option to select Safe apply with a time. See figure below. Figure 7 - Apply button and "safe apply" option visible after the "Set" button is clicked. 5. For the new setting(s) to take effect, click the Apply button (you can change several parameters before clicking Apply ). This might cause the browser to lose contact with the web GUI for a short while. When it is back, the new configuration area is active and stored in the RAM memory. To make the changes permanent you have to click Save as shown in the figure below. Figure 8 - Select Save in order for the new configuration to be permanent. 6. If Safe apply was selected before Apply was pressed, the unit will roll back to the current (working) configuration after the stated time if you lose the node after reboot. The default time is 5 minutes. It is strongly suggested to use the Safe apply option for field mounted links as it will bring your link back in operational and manageable state even if you make configuration mistakes that makes you lose the node.

21 Rolling back settings Figure 9 - The configuration has to be saved, otherwise they are lost after the next node restart. The Trinity-300 series system allows you to roll back settings if you happen to misconfigure a unit. To rollback settings, use the Load configuration feature present in the left status pane. Figure 10 - Load configuration The drop-down box contains a list of available configuration areas where existing configurations can be loaded from. To revert back to the settings stored on flash, you would select Stored settings from the drop-down list and press the Load button. The new settings are placed in the inactive area, which means you have to apply and save when done. Restore to default You can load the Factory defaults to restore the unit to a basic working condition. It is also possible to restore the unit to default settings in one action without the need for an explicit Apply and Save by using the dedicated Restore to default function available on the Admin tab or by using the Repeatit RTD client software, see section 3.4 for more information on this. 2.3 Configuration parameters Out of the numerous configuration parameters that can be set in the Trinity units, some are only available on Master units. The

22 following section describes the available configuration parameters in more detail. Radio settings The radio settings control parameters related to the radio interface. Mode A Trinity unit can operate in three different modes as described in the table below. Point-to-Point Master Multi-Point Master Client Defines the channel to operate on and the distance to its client. Which client that is allowed to connect is determined by the remote MAC address setting. Same as Point-to-Point Master, except it will allow multiple clients to connect at the same time, on a timeslot division basis. In Multi- Point Master mode, use the 'Client settings' menu to configure timeslot allocation etc for the clients. The client will attempt to connect to any master that matches its configured remote MAC address. Remote MAC Radio device MAC address of the remote peer. Channel Specifies which radio channel that should be used. Selecting Auto channel will make the unit sweep the spectrum and select a channel free from other transmissions. Only required on the Master side. Note For European ETSI domains the frequency range GHz is solely for indoor use. It is not allowed to use channels within this band in an outdoor installation. Min Transmit rate This setting configures the lowest allowed modulation to be used. Will be clamped to Max Transmit rate if set to higher rate than Max Transmit Rate. Note that when in Multi-Point Master mode, this setting only applies to broadcast/management traffic, the Min Transmit rate to the clients is set individually in the

23 'Client settings' menu (this menu is only available when the node is set to operate as Multi-Point master). Max Transmit rate This setting actually configures the modulation used for transmission. If you change the "Channel bandwidth" the same modulation will be used but the actual data rate is changed as reflected by the bitrate displayed. The transmission always uses auto-rate. so the actual used modulation can be lower than the configured value due to interference or fading of the signal. Note that when in Multi-Point Master mode, this setting only applies to broadcast/management traffic, the Max Transmit rate to the clients is set individually in the 'Client settings' menu. Link ID A link ID is an arbitrary, up to 32 character long link identifier, that allows you to differentiate between multiple links. The link ID must be equal on the master and client for a connection to be established. Passphrase The passphrase is the encryption key that has to be set (and match) on both sides of the link. Regulatory domain The frequency band is divided up into channels, with each local regulatory agency defining what is permitted for use in its area. This effects the available channels.

24 Prefered channels Any known bad channel selections can be disabled here, this will stop radar roaming to those channel. Channel bandwidth The bandwidth determines the spacing between available channels and how the frequency spectrum is divided. This effects the available channels. Channel space Controls the steps between individual channels. The default value is Auto. This should only be used in special case. If you are unsure about what rate to use, please turn to your distributor. Max transmit power per chain TxPower (in dbm) of the signal transmitted from the radio. Most regulatory domains have a limit on how high the transmit power plus antenna gain may be. Master/Client time division How the send time is divided between Master/Client. For example 50/50 means that both the Master and the Client get access to 50% of the total air time. In most deployments, it is a good idea to assign more resources to the downlink direction (Master to Client) as the traffic normally is heavier in that direction.

25 Max Tx rate master Maximum data rate from the master unit. Note! The value does not always reflect the actual maximum capacity. The capacity could be limited by other settings like channel bandwidth and division of time between master/client. A low limit can destroy for the built in speed test. Max Tx rate client Maximum data rate from the client unit. Note! The value does not always reflect the actual maximum capacity. The capacity could be limited by other settings like channel bandwidth and division of time between master/client. A low limit can skew the built in speed test. CAC policy This will allow you to control the DFS CAC (Channel Availability Check, i.e. the amount of time to listen for radar before using a channel) policy. Selecting Regulatory will follow the rules according to the selected regulatory domain, this is the recommended setting. Selecting Custom will allow you to enter a custom DFS CAC time. Note Note that in Europe, according to the ETSI EN regulation, there is a 10 minute CAC time on the 5.6GHz band due to weather radars. O Enable reordering Re-order packets via buffering to reduce the number of out-oforder packets. Enabling this option will increase latency when out-of-order packets occur. Always buffer Buffer all packets, not only those that need re-ordering. Increases average latency, but reduces variations in latency (jitter). Reordering level

26 Regulates how much buffering that is used. Higher level removes more out-of-order packets but increases latency. Network settings IP IP-address on this Trinity-300 series unit. Netmask IP-netmask to use. Gateway Specifies the default gateway for this unit. VLAN VLAN (IEEE 802.1Q) ID, range DNS QoS settings Note Configuring an invalid VLAN ID might result in the loss of Ethernet connectivity if the there is a mismatch with your switch configuration. Specifies one or more name servers. The default configuration contains two working servers. Ethernet speed Allows for Ethernet speed configuration. The default value is Auto-negotiation. Enable SNMP Enable SNMP version 2c for monitoring. QoS settings Allows for Pbit (Ethernet Layer 2 QoS) to DSCP (IPv4) mapping. System settings Unit name Allows you to specify a custom unit name for easier identification. Location

27 Allows you to specify a descriptive name for the units geographical location. Latitude Latitude for node location on digital map. Could also be selected by the Select location on map or Get location buttons Longitude Longitude for node location on digital map. Could also be selected by the Select location on map or Get location buttons. Contact Administrative contact person for this unit. Status LED Visual signal level/link status indicator. Can be set to pulse mode or disabled. If set to pulse mode the LEDs will blink according to the current signal strength. Buzzer Auditory signal level/link status indicator. Off - No sound. Combined - Indicate for the weaker of both chains. Chain 1 - Indicate for chain 1 only. Chain 2 - Indicate for chain 2 only. Signal indication sounds: 0.3 s beeps at 0.33 Hz - In radar or test scan, signal strength indication unavailable until it's completed s beeps at 0.33 Hz - No connection s beeps at 1 Hz - Connection in progress s beeps at Hz - Connected with valid signal, faster beeping for stronger signal. 0.4 s beeps at 2 Hz - Signal excessively strong. Note: Beeping turns off 15 minutes after startup or settings change regardless of setting. Use a syncmaster The SyncMaster is a unit that allows several links to operate on the same channel at the same time at a site. Refer to Repeatit s SyncMaster white paper for more information.

28 Syncmaster identity The unique identity of a SyncMaster. VLAN id The VLAN id for SyncMaster packets. By default set to 0 (untagged). Policy for lost connection to syncmaster Should the link raise an alarm and go down if the SyncMaster is lost or keep on without the sync? Enable cloud management server Login to the free cloud management server. Use RCS Enable/Disable the use of Repeatits network management system RCS. RCS IP/host The IP address of the RCS server. SSL Port SSL port number for the RCS server. The default port number is Password Password for node communication with the RCS server. NTP Enable/disable the usage of NTP (Network Time Protocol) and which NTP servers to use.

29 U O Unit Operation 3.1 Status view The status view is the first page you see when accessing the web GUI of a Trinity-300 series unit. This page gives you a fast overview of the link and unit status. Figure 11 Status view. Graphical status indicators The upper part of the status view holds a number of graphical status indicators (see figure below). The Ethernet and Radio link status are displayed in the upper left corner. An indication bar shows if the unit is a Master or a Client and gives the connectivity status. The Link qualities for the two antenna branches are also shown, both graphically and as two dbm (and RSSI) values. The dbm values show the actual signal strength as measured by the equipment while the RSSI level is measured as the difference in received signal strength and noise floor level. Repeatit s Deployment Guideline explains how to interpret the signal levels and how to install antennas so the link quality is optimized. The two chains should have similar (+/- two-three db) signal strength if antenna alignment has been done successfully. U O

30 U O Figure 12 - The upper part of the status tab gives an indication of Ethernet/Radio connectivity and radio link quality. Radio status Right below the graphical status bars, the Radio Status information is displayed. See figure below. Figure 13 - Radio status information Below is a short description of the Radio Status parameters. Frequency The current frequency of operation. Channel The current channel that is used by the link. Channel bandwidth The frequency bandwidth used by the link. Note that there is a dependency between frequency used and available Tx Power for the link. If the frequency is doubled, the average output power is reduced with 3dB. Time division Tx/Rx How much of the air time that is used in Tx (from Master) and Rx (from Client). 50/50 divides the time equally in both downlink/uplink. Noise level U O

31 U O The background noise measured by the receiver (dbm). Signal level The received signal level on incoming packets as measured by the receiver (dbm). Tx Rate The Tx Rate of the last incoming packet. By monitoring this value, you get a feeling of which rate the link actually uses. Note that you should check the rate at both sides of the link to get the full picture. If the rates differ a lot, it is a sign of that one of the sites could be subject to noise or interference from an external source. RSSI Ctl Chain1 / Chain2 The Received Signal Strength Indicator (RSSI) of the main channel s both antenna chains. The main channel refers to the first 20MHz used by the link. If you use less than 20MHz, the RSSI levels will also be shown here. RSSI Ext Chain1 / Chain2 In cases where an additional 20MHz spectrum is used by the link, the RSSI for that spectrum is shown here. So this row will only be visible when 40MHz spectrum is configured for the link. Remote radio status The figure below shows the status information of the remote radio. The parameters are described below. Tx Rate Figure 14 Remote radio status (other side of the link). The Tx rate used by the other side of the link. Should be similar to the own Tx rate (described above). RSSI Ctl Chain1 / Chain2 The Received Signal Strength Indicator (RSSI) of the remote radio main channels both antenna chains. The main channel refers to the first 20MHz used by the link. If you use less than 20MHz, the RSSI levels will also be shown here. U O

32 RSSI Ext Chain1 / Chain2 U O In cases where an additional 20MHz spectrum is used by the link, the remote RSSI for that spectrum is shown here. So this row will only be visible when 40MHz spectrum is configured for the link. Link status The figure below shows the status information of the radio link. The parameters are described below. Link uptime Figure 15 Link status. The time the link has been up since last power up, reconfiguration or reboot. Remote MAC The read MAC address of the remote side of the link. Current Max Theoretical Throughput Tx/Rx The max theoretical throughput shows what to expect from the link. It takes into account the Tx/Rx time division and removes system overhead. System status The figure below shows the system status information. The parameters are described below. Figure 16 System status. Uptime The overall system (node) uptime. Cloud server Connectivity status of the RCS server (Enabled/Disabled). RCS U O

33 The IP address of the RCS server. U O Syncmaster Connectivity status of the SyncMaster. If no SyncMaster is configured, the state is Disabled. Ethernet The actual rate used on the wired Ethernet link. Radio statistics The figure below shows the radio statistics information. Note that these statistics are aggregates of the last five seconds and that they are intended to be used mainly for troubleshooting purposes. As some types of transmitted data frames have been removed from this view, the statistics will not give a good picture of what the actual link throughput is, just what the link performance looks like. The parameters are described below. Throughput Figure 17 Link status. The TX and RX throughput is mainly used for troubleshooting purposes. Increase in injected traffic reflects in an increase of throughput. Total packets The total packets show how many data packets that have been acknowledged by the remote end over the past 5 seconds. Not acknowledged frames, management/broadcast frames and control frames are excluded from the statistics. Success data Acknowledged frames over the past five seconds. Retransmissions are not counted. Retries U O

34 U O A frame that is dropped a number of defined times will eventually be retransmitted. A lot of retries indicated severe link problems. Check the PHY errors for more details. Excessive retries This is the number of radio frames that have been retransmitted the maximum number of times without success, and hence are dropped. Duplicates If the receiver gets the same packet more than once, it means the remote end has not received the acknowledgement packet for the first transmission. Duplicates indicate how many copies of the same packet that was received during the past 5 seconds. Checksum errors When a receiver detects the start of a frame and can read the header but not decode the frame content, a checksum error is generated. Many checksums errors could on one side of the link indicates interference on that side. PHY errors When a receiver sees energy over a certain threshold but cannot decode anything, it generates a PHY error. If one of the link units (Master or Client) is subject to interference or increased noise floor (from other equipment in the vicinity), the PHY error rate may increase. Consider moving the equipment or change channels. The spectrum scan tool gives useful information (see tools section in this document or refer to Repeatit s Deployment Guideline). Radar PHY errors Total number of PHY errors received by the radio card that could be potential radar signals. If the link is subject to radar PHY errors, consider selecting a channel outside of the radar frequency band. Remote statistics The figure below shows the remote statistics (the other side of the link). The parameters are described below. Figure 18 System status. U O

35 Retries U O The number of retransmitted frames over the past 5 seconds. Excessive retries This is the number of radio frames that have been retransmitted the maximum number of times without success, and hence are dropped. Duplicates If the receiver gets the same packet more than once, it means the remote end has not received the acknowledgement packet for the first transmission. Duplicates indicate how many copies of the same packet that was received during the past 5 seconds. U O

36 U O 3.2 Link Diagnostic Tools The Tools page contains diagnostic tools for optimizing your Trinity- 300 series link. Spectrum analyzer Figure 19 Tools page. The spectrum analyzer tool assists you in selecting a clear channel free from other radio traffic and with minimum amount of background noise. The spectrum analyzer shows the amount of environmental RF energy for each available channel, classified as valid OFDM signals and other RF noise. Refreshing the spectrum/noise information requires the unit to disable the link and listen for a short time (less than a second) on each channel, this operation might take several minutes to complete, and during this time the link will be out of service. Figure 20 Spectrum analyzer. Note The radio traffic will be disabled during the time the U O

37 analyzer is running! U O Speed test The integrated speed test will show you the available raw radio throughput (±10%) of your link. The speed test takes approximately 5-10 seconds to complete and does not interrupt normal traffic. Up to 10 test runs are stored (4 shown in the figure below) so that you are able to monitor improvements or link degradations. Figure 21 Speed test. U O

38 U O 3.3 Firmware upgrading The Admin page contains diagnostic tools for optimizing your Trinity-300 series link. Figure 22 Admin page. The firmware in a Trinity-300 series unit is upgradeable. New firmware brings both bug fixes and new features to the unit, so we recommend that you visit Repeatits web site frequently to look out for new firmware versions which are downloadable from there. To upgrade the firmware, follow the steps below. 1. Download the latest software to your computer from Repeatits web site ( The result should be that you have the.img file stored. Figure 23 Download the latest Trinity firmware from the web site. 2. Navigate to the Admin tab in the unit s web interface and select Firmware upgrade. Figure 24 Click Upgrade Firmware on the web GUI s Admin page. U O

39 U O 3. In the pop-up window, click the Choose file button ( Välj fil in the picture below), localize the.img file that you downloaded and then click Upgrade Firmware. Figure 25 Select file and click Upgrade Firmware. 4. When the firmware is loaded and written to the flash disc, the node has to be rebooted (you can select this to be automatically done). When you get the message that the node is rebooted, you can close the window. The unit should be accessible shortly after that. Note Never plug out the power or interrupt a firmware upgrade in some other way. Tip Always upgrade the unit on the remote side of a link first when performing a firmware upgrade 3.4 Restore to defaults There are three ways to restore a unit to its factory default settings. 1. On the Admin tab in the web interface you can chose to restore settings to f actory default in a single operation. Note that the unit will automatically reboot after this. Figure 26 Reset to factory default in the Admin view. U O

40 U O 2. In the Configure view you can load the factory defaults in order to look at those settings before they are applied. 3. There is also Restore to default client software available at This software will automatically detect any Repeatit units within the first few minutes after boot, and allows you to restore the unit to its default settings.

43 Usage restrictions and legal information This product contains radio equipment for which the use in several countries is subject to restrictions, licenses or government authorization. European Union Notices The product may be used in all EU countries (and other countries following the EU directive 1999/5/EC) without any limitations except for the counties mentioned below. In EU and other European countries, the 5-GHz bands have been made available for the use of wireless local area networks (LANs). The overview of Regulatory Requirements for wireless LANs table provides an overview of the regulatory requirements applicable for the 5GHz bands. Requirements for individual countries may change, Repeatit recommends that you check with your local regulatory agency for the latest status on regulations for 5GHz fixed radio links. Overwiew of Regulatory Requirements Frequency band Max power level mw (EIRP) Usage (23 dbm) Indoor ONLY (30 dbm) Indoor and outdoor The Regulatory limits for maximum output power are specified in EIRP (Equivalent Isotropic Radiated Power). The EIRP level of a device can be calculated by adding the gain of the antenna used (specified in dbi) to the output power available at the connector (specified in dbm) minus antenna cable loss between the connector and the antenna (in db). The usage of power levels above the maximum specified EIRP is illegal.

44 U Denmark In Denmark, the band MHz is also allowed for outdoor useage. Italy The use of 5.8GHz ( MHz) is forbidden in Italy. United Kingdom A license from Ofcom (ofcom.org.uk) is required for use of the 5.8GHz ( MHz) band in the United Kingdom. U
