||DFS fails on Cisco FM1200 Volo radio transceivers|
On Cisco Ultra-Reliable Wireless Backhaul (formerly Fluidmesh) FM1200 Volo radio transceivers, the Dynamic Frequency Selection (DFS) function might fail to detect Unlicensed National Information Infrastructure (U-NII) frequencies in client mode or might fail to cease emitting when a U-NII frequency is detected.
On Cisco FM1200 Volo radio transceivers, the DFS function might fail to detect U-NII frequencies in client mode or might fail to cease emitting when a U-NII frequency is detected.
Cessation of transmission upon detection of U-NII frequencies is mandatory for proper use of the radio spectrum under Article 3.2 of European Union Directive 2014/53/EU, as well as under local country regulations within the European Union. This capability is also highly recommended for deployments outside the European Union.
For additional information, see the Cisco FM1200 Volo Firmware Release Notes.
The device will appear to work normally, but will be out of compliance under Article 3.2 of European Union Directive 2014/53/EU and local country regulations.
There is no workaround.
The customer must upgrade all FM1200 Volo radios to image FM1200-gen2-7.7.2.bin or later.
The customer must upgrade the device firmware with these steps:
- Ensure that the radio’s country selection is set to a country where the device is located. For example, France within the European Union.
- Upgrade the device firmware to version FM1200-gen2-7.7.2.bin or later.
Note: For new FM1200 Volo radios that have NOT yet been configured and run firmware earlier than FM1200-gen2-7.7.2.bin, complete steps 1 and 2 and then reset the radio to the factory default configuration. Refer to the section Resetting the Unit to Factory Settings in the Cisco Ultra-Reliable Wireless Backhaul FM1200 Volo Installation and Configuration Manual. After the device reset, the radio will now be ready to accept custom configuration settings.
