    Deploying an Existing CFL to a Spectrum Manager


    It is assumed that a compatible frequency list (or CFL) was calculated offline while not connected to any gear. When connecting to the gear, ensure that the Spectrum Manager(s) and all subordinate devices are discovered in the Inventory View.

    Deployment and the CFL

    Currently, the CFL that was calculated offline lives inside Wireless Workbench, and will be saved with a show file. To send out a CFL to a Spectrum Manager, a deployment must be performed. This is the case when deploying an existing CFL, or a brand new one as a result of coordination.

    The Spectrum Manager retains a CFL through a power cycle. If this is not the first time you are using your Spectrum Manager, it is likely that there will already be a CFL stored in its memory. You must delete the currently stored CFL from the Spectrum Manager in order to not merge old (and potentially incompatible) frequencies with your CFL.

    A quick way to verify whether or not your Spectrum Manager has a CFL is to discover the device (so that it shows up in the inventory view), and open the Frequency List window. Select the "Frequency List" button from the global menu bar to access this window.


    You should see two columns of data in the Frequency List window. One of the columns will represent the deployment and frequency list hosted by Wireless Workbench; this will be the one with the Spectrum Manager value listed as "None" at the top of the column.


    The column on the left in the image above shows the CFL that was already in the Spectrum Manager when it was discovered. You can also tell that this section of the Frequency List window is managed by a Spectrum Manager, as the backups list has colored LEDs and dBm values that live update as the frequencies are being monitored (this functionality will only be available when a Spectrum Manager is present).

    In order to get our known and trusted CFL into the Spectrum Manager, we will clear the device's currently hosted CFL.

    Note that both Frequency Lists (one hosted by Workbench, and one hosted by the Spectrum Manager) belong to the zone "Default". Deleting the CFL from the Spectrum Manager will begin the process to consolidate these two into a single Frequency List.

    Clear a Spectrum Manager's Current CFL

    From the home screen on the right side of the Spectrum Manager, press "CFL".


    Select "More".


    Select "Clear" to erase the CFL from the Spectrum Manager.


    Press the green blinking "Enter" button to confirm.


    You will see the message "No Compatible Frequency List" when the CFL has been successfully erased.


    To confirm that the Spectrum Manager does not have a CFL, go back to Wireless Workbench and inspect the Frequency List window. You should see that the column of frequencies managed by the Spectrum Manager is now empty affirming the fact that the old CFL hosted on the Spectrum Manager has been destroyed.


    Deselect all channels so they remain on their current frequencies

    Go to the Frequency Coordination tab, and select "Manage Channels"_" from the right sidebar. The Channel Summary dialog will open.

    Press the Select: "None" button to uncheck all devices. This will ensure that all devices stay on their current frequencies.

    Before you close this dialog, be sure to press "Refresh Live Backup List". This button will keep your list of backup frequencies is in sync with the current state of the hardware/backup list.


    Select "OK" to confirm.

    From the right sidebar of the Frequency Coordination tab, select "Calculate New Frequencies" to initiate the coordination, which we just configured to not calculate any new frequencies.


    The summary on the RF Coordination Results will indicate this as well, showing that zero frequencies were calculated for devices as well as backups. After this null calculation, we can now configure Wireless Workbench to deploy our known frequency list to the Spectrum Manager.

    Spectrum Manager assignment for each zone

    Ensure that each zone with devices assigned to it has its corresponding Spectrum Manager. This assignment is made by selecting the appropriate Spectrum Manager for each zone from the drop-down at the top of the "Summary" section.


    This is how Wireless Workbench will know which Spectrum Manager should receive each CFL. Note that the associated Spectrum Manager must also be in the same zone as the devices it will manage.

    By selecting "None" for a given zone, Wireless Workbench will internalize that CFL, and save it within a show file. This is how offline results can be saved without access to a Spectrum Manager.

    NOTE: Only one Spectrum Manager can manage a zone and it's CFL at a given time. This means you will need one Spectrum Manager per zone for which you would like backup monitoring and automatic frequency dispatching to AXT400 receivers.

    Sending out the CFL

    Press "Deploy to Inventory" to send the CFL to the designated Spectrum Manager.


    To confirm that the Spectrum Manager has received the CFL, go to the device's front panel and select CFL -> Edit to display the Spectrum Manager's full CFL. Check this list to ensure that all frequencies that were a part of your frequency list were transferred.

    Another way to confirm that the Spectrum Manager has received the desired CFL is to open the Frequency List window. You will notice that there are no longer 2 columns, but instead, one with the CFL from your past coordination. Also, that CFL will have a Spectrum Manager assigned to it, and listed at the top of the column.
