This template is to allow a change of the “Center Frequency” and “Channel bandwidth” on your PMP450 series AP from within cnMaestro. This can be done on a per AP basis or as a bulk update if coordinating a frequency plan across multiple sectors/towers.

To add the template to cnMaestro, go to “Configuration > Templates”, and click “Add Template”, and then either upload the attached JSON file or paste the contents of the JSON into the text field and then click “Save”.

Once the template is uploaded, you can now configure the new bandwidth and channel you wish to change on a sector per sector basis by clicking on the “” icon.

Please note: Both variables are required to be populated for the template to save.

After you have configured all the sectors that require the new channel bandwidth or center frequency reconfigured, make sure to tick the box next to the AP to enable the template sync for the device.

You can either sync the template to the devices immediately or schedule them if you wish to run the configuration change closer to CPAS.

Please Note: This template has the “rebootIfRequired” flag set to “true” for use on the PMP450m AP. Changing the channel bandwidth on a PMP450m will trigger a reboot when the config is applied. The PMP450 and PMP450i do not require a reboot to change the channel bandwidth.
