Follow these steps to mount and ground the B24 Radio. 1. Attach the precision alignment mount to the bracket with the provided bolts. Attach the mount to your desired pole using the provided pole clamps. 2. Copyright 2018 Mimosa Page Page 1 Mimosa Backhaul and B24 Help Content Mimosa Backhaul Mounting & Grounding 3. Aim the radio horizontally by sliding the the mount around pole until it is pointing in the desired direction. To fine tune the radio, use the Elevation and Azimuth adjustment allen bolts, then check and tighten each of Elevation and Azimuth locking bolts. 1. Attach a 6 mm2 (10 AWG) ground wire with a maximum length of 1 m (3.3 feet) between the mounting bracket of the B24 and a suitable grounding location on the tower or structure. The provided grounding screw is M5 x 6mm with 0.8 thread.

Hardware & Materials - Details about what materials are used in each provided part. Copyright 2018 Mimosa Page Page 3 Mimosa Backhaul and B24 Help Content Mimosa Backhaul Mounting & Grounding Installation, Mounting and Alignment 1. You will need a 10mm wrench, a #5 hex wrench/allen wrench, and a 5/16 nut driver to mount and align the 2. B24. Take the mounting bracket and attach it to the B24 using the two provided screws. Use your 10mm wrench to tighten the screws down. When youre ready to adjust elevation, these two screws will need to be loosened up. Add both hose clamps to the B24 mount when youre ready to mount to a pole, j-mount, etc. Once on the pole, tighten down your hose clamps most of the way so that they hold the radio up on the pole. 3. 4. Copyright 2018 Mimosa Page Page 4 Mimosa Backhaul and B24 Help Content Mimosa Backhaul Mounting & Grounding 5. 6. 7. 8. 9. 10. Before tightening your hose clamps down all the way, go ahead and point your B24 toward the other end of the link (coarse alignment). Once you have your radios pointed, go ahead and tighten down the hose clamps. If you have planned this link out in the Mimosa Design Tool, you will know the -+ degree of the elevation. Go ahead and set your mount to around the correct angle. Keep in mind that each tick mark for elevation is 5 degrees. Power up the B24 radio so that you can connect to the radio GUI through 2.4GHz Wi-Fi or Ethernet. Once the radios are powered up, you should be able to tell if the radios are linked up or not by looking at the LED light on the back. If you have a blue flashing light, your link is connected. Regardless if your link is connected or not, log into the radio and access the radio GUI. On the Dashboard page, you will see the Signal Meter. If connected, youll have a signal level listed. Please make sure you are only adjusting one radio at a time. Also make sure you are not adjusting azimuth and elevation at the same time. You want to complete one before starting the other. Now that the radio is powered up, and youre logged into the radio, you can start the fine adjustment process. Loosen up the hex head screw labeled AZ LOCK using your #5 hex wrench and your 10mm wrench. Failure to loosen this screw will prevent you from adjusting the horizontal/azimuth on your B24 mount. Now take your hex wrench and insert it into the hex screw labeled FINE AZ. Turning clockwise will move your radio to the left, while turning counter-clockwise will move your radio to the right. Pick a direction and start turning. Watch the signal meter to see if your signal is getting better or worse. Copyright 2018 Mimosa Page Page 5 Mimosa Backhaul and B24 Help Content Mimosa Backhaul Mounting & Grounding Even if your signal is getting better or worse, continue turning for a few more turns to determine if youre connected to a side lobe or not. If you are the signal will get worse and then much, much better. Once you have adjusted left and right, move back to where you had the best signal. To adjust elevation, make sure to loosen the two 10mm bolts labeled ELE LOCK. If you recall, these were the two bolts used to attach the mount to the B24. Take your hex wrench and insert it into the hex screw labeled ELE. Turning clockwise will reduce the elevation of your radio, while turning counter-clockwise will increase the elevation of your radio. Pick a direction and start turning. Watch the signal meter to see if your signal is getting better or worse. Even if your signal is getting better or worse, continue turning for a few more turns to determine if youre connected to a side lobe or not. If you are the signal will get worse and then much, much better. Once you have adjusted left and right, move back to where you had the best signal. Now that you have adjusted one end of the link, follow the same steps to align the other end of the link. Once both radios have been aligned, go ahead and gently tighten the AZ LOCK screw and the ELE LOCK screws. Once these are tightened down, and youve confirmed your signal levels, you will have completed installation and alignment of your radio link. 11. 12. 13. 14. 15. 16.

Copyright 2018 Mimosa Page Page 8 Mimosa Backhaul and B24 Help Content Mimosa Backhaul Overview Accessing the Graphical User Interface Accessing the graphical user interface (GUI) requires that the radio first be connected to power. The Power over Ethernet (PoE) connection process describes the steps to do this. Note that the GUI will be available approximately one minute after applying power. The GUI can be accessed in three ways to facilitate set-up and management. 1. 2. 3. Locally through the built-in 2.4 GHz wireless management network (B5/B5c and B11 Only) Through the local Ethernet interface (LAN), or the fiber (SFP) if applicable Remotely through the Point to Point wireless link Via 2.4 GHz Management Network On any device with 2.4 GHz 802.11n capability, go to the wireless network listing and connect to the Local Network Management wireless network (SSID): "mimosaMXXX". The default passphrase for the 2.4 GHz connection is

"mimosanetworks". Once connected, type 192.168.25.1 into your browser. Please note that both the Local Network Management SSID and passphrase are configurable by the user, so their values could be different from the default values. Via Ethernet interface or in-band over the Point to Point link By default, the device IP address is 192.168.1.20 and can be accessed via the Ethernet port using this IP address in any standard Web browser. To access the device via a locally connected computer initially (on the same LAN or directly to the Ethernet port), the computers IP address must be on the same subnet as the above address. Once you have modified the IP address (static or is DHCP) of the device for remote management purposes (in-band over wireless or over the Ethernet interface), the new specified IP address must be used to access the device. This is important to do in order to avoid IP address conflicts with other devices on the network. Current IP addresses of different Mimosa devices on the network can be identified using terminal-based discovery. It is highly recommended to change the default password to a unique and secured password. Copyright 2018 Mimosa Page Page 9 Mimosa Backhaul and B24 Help Content Mimosa Backhaul Logging In Overview After connecting via one of the three access methods, the GUI will prompt you to log-in with a password. The default password is "mimosa", and should be changed immediately after login to protect your network since it gives the user read / write privileges. The password can be changed within the Preferences > General > Set Password panel of the GUI. Copyright 2018 Mimosa Page Page 10 Mimosa Backhaul and B24 Help Content Mimosa Backhaul User Interface Overview Overview When you first log in, youll notice that there is a title bar with the device name shown in the top-right corner, a navigation pane on the left, and a large content pane on the right. The default page shown in the content pane is the Dashboard, which shows a summary of overall performance at a glance, and highlights both radio and link parameters that affect link health. On the left navigation pane, there are four prominent sections: Overview, Wireless, Preferences, and Diagnostics. Each of these sections contains one or more links to pages containing task-related data, controls, and tools used to administer the radioand you can return the Dashboard at any time by clicking on the Dashboard link in the Overview section. The pin in the top corner of the left navigation pane allows you to "pin" open the navigation menu for easier access. Else, the menu contracts to provide more workspace within the GUI.

While viewing the Aiming Mode screen, move the local antenna on one axis at a time (first azimuth and then elevation) in 6mm (1/4 inch) increments. Wait 2-3 seconds for the signal to settle after each movement. Signal strength may increase or decrease after each movement. Increases in signal strength will move the green arrow and blue shaded region closer together. Decreases in signal strength will move them farther apart. The point of maximum signal strength indicates optimal antenna alignment for each axis. Repeat the steps 1 and 2 above on the remote antenna. The signal strength should match the outputs from the Mimosa Design application. If not, please consult the Low Rx Power troubleshooting guide.

The newest data shows up on the right and scrolls to the left over time. You can toggle between the charts by clicking on the navigation circles at the bottom of the panel. If enabled, click on the cloud icon to view historical data within the Manage application. The IP Throughput graph plots three lines representing transmit, receive, and aggregate (summed) throughputs at the datagram (or packet) layer excluding any protocol or encapsulation overhead. The results here may differ from those measured using speed test tools, due to protocol overhead and encapsulation. Note that internal Bandwidth test results are excluded. The Packet Error Rate (PER) is the number of packets with errors divided by the total number of packets sent within a 5-second period. Ideally, this value should be below 2%, while higher values indicate the presence of interference. Tx PER is an indication that the local radio did not receive an ACK from the remote radio, so is forced to retransmit the same information again. Rx PER is a value sent from the remote radio to the local radio in management frames. Copyright 2018 Mimosa Page Page 19 Mimosa Backhaul and B24 Help Content Mimosa Backhaul Dashboard Note: PER will be higher upon initial association, and will usually settle within 30-60 seconds. This is Note: PER will be higher upon initial association, and will usually settle within 30-60 seconds.

Chains represent the physical medium (RF Tx/Rx values), while Streams represent data. Chains and Streams are not necessarily correlated one to one because the Rate Adaptation algorithm may periodically increase or decrease the number of data streams sent over the physical medium when reacting to interference. The Chains table describes each chain's power, noise, SNR, frequency and polarization. The Streams table describes each stream's MCS index, PHY rates and Rx Error Vector Magnitude (EVM). Each table can be selected by clicking on the navigation circles at the bottom of the panel. Chains The Chains table contains 6 values: Tx Power, Rx Power, Rx Noise, SNR, Center Frequency and Polarization. Each channel is assigned two chains (horizontal and vertical). If two channels are selected, Channel 1 uses Chains 1 & 2, while Channel 2 uses Chains 3 & 4. Tx Power is the amount of power applied to each of the MIMO chains. Tx Power can be shared evenly (preferred), or unevenly (if necessary), between channels. The Tx power Tx Power can be shared evenly (preferred), or unevenly (if necessary), between channels. The Tx power per channel is divided evenly per chain. Example: 4 dBm Tx power on Channel 1 results in 1 dBm each on per channel is divided evenly per chain. Example: 4 dBm Tx power on Channel 1 results in 1 dBm each on Chains 1 & 2. Chains 1 & 2. Rx Power is the incoming signal level from the remote radio. Larger values are better (e.g. -50 dBm is better than -

60 dBm). Rx Noise is a combination of the thermal noise floor plus interference detected by the local radio. Smaller values are better (e.g. -90 dBm is better than -80 dBm). Noise sources can be either in close proximity to the local radio, or they can be remote transmitters pointed back at the local radio. Copyright 2018 Mimosa Page Page 24 Mimosa Backhaul and B24 Help Content Mimosa Backhaul Dashboard The signal-to-noise ratio (SNR) is the difference between the Rx Power and Rx Noise, and is a measure of how well the local receiver can detect signals from the remote transmitter and clearly discern them from noise. Higher values are better (e.g. 30 dB is better than 10 dB). If two channels are selected, you may observe that SNR is much lower on one channel than the other. This could be because the Tx Power is set lower on the remote transmitter, or because of higher interference levels on the channel. To resolve this, increase Tx Power or change the channel that has lower SNR. Chains 1 & 3 have horizontal polarization, and Chains 2 & 4 have vertical polarization. Chains with the same polarization are combined internal to the radio before exiting to the antenna connectors. Streams The Streams table contains the Tx MCS index, Tx PHY rate, Rx MCS index, Rx PHY rate, and the Rx EVM for each stream. The Tx MCS is an indicator of how well the remote radio can receive data from the local transmitter. The Rx MCS indicates how well the local radio is receiving data from the remote transmitter. The Modulation Coding Scheme (MCS) represents how much data can be sent at a time, so directly affects The Modulation Coding Scheme (MCS) represents how much data can be sent at a time, so directly affects potential throughput represented by the PHY rate. The higher the MCS index (ranging from 0-9), the more potential throughput represented by the PHY rate. The higher the MCS index (ranging from 0-9), the more data that can be sent per transmission. A disadvantages of higher MCS indices is that they require higher data that can be sent per transmission. A disadvantages of higher MCS indices is that they require higher SNR since they are more vulnerable to noise. SNR since they are more vulnerable to noise. The Error Vector Magnitude (EVM) indicates the difference between the actual and expected amplitude and phase of an incoming signal. Smaller values are better (e.g. -30 dB is better than -10 dB). Rate Adaptation dynamically adjusts both the MCS and the number of streams depending on RF conditions. Poor RF conditions (i.e. interference) causes PER to increase. PER and MCS are inversely correlated meaning that as PER Copyright 2018 Mimosa Page Page 25 Mimosa Backhaul and B24 Help Content Mimosa Backhaul Dashboard increases, MCS decreases and vice versa. Single channel mode usually uses 2 streams, but may drop to one stream if RF conditions are poor. Dual channel mode uses up to 4 streams. You may also see the number of streams change periodically because of tests that Rate Adaptation performs to optimize performance. This is expected and normal. Related:

This is a low power interface that performs best if accessed within 60 meters (~200 feet) of the radio. It is completely separate from the link and has no performance impact on throughput if activated. l l l l l Network Mode - Choose to automatically or manually enable or disable the 2.4 GHz management network. The automatic mode turns the 2.4 GHz management network on for a limited time (defined in Console Timeout) after boot and then turns it off if there is no activity. If a user associates with the radio within the timeout period, they will not be disconnected. Console Timeout - Set the number of minutes (1-60) of inactivity that will be allowed on the 2.4 GHz interface before turning it off in Auto mode. SSID (Local Management) - Set the SSID name for the 2.4 GHz local management interface. Channel - Select the channel on which the 2.4 GHz wireless network will operate. Recovery SSID - This is an non-editable recovery SSID that allows the device to be reset to factory defaults. This is available for 5 minutes after device boot. Disabling the 2.4 GHz management network will not impact availability of this option. The serial number of the device must be known in order to perform the factory reset. Note: If you turn off the 2.4 GHz management radio, you can still access the device through the wired LAN interface, or in-band through the 5 GHz wireless link. During the B5/B5c device reset process, the 2.4 GHz wireless interface is briefly re-enabled, and then disabled after a timeout.
