Monitoring the RF Environment Growing Your Network
1. transform all APs in a cluster into SMs.
2. perform spectrum analysis without Management VLAN, one sector at a time.
3. return all APs in the cluster to their Management VLAN for access.
To transform a VLAN-enabled AP into an SM for spectrum analysis and then return the device to
an AP, perform the following steps.
Procedure 32: Using the Spectrum Analyzer in AP feature, VLAN enabled
1. Access the VLAN-enabled AP through its Management VLAN.
NOTE: How you do this depends on your local configuration.
2. Access the General tab of the Configuration page in the AP.
3. Set the Device Setting parameter to SM.
4. Click the Save Changes button.
5. Click the Reboot button.
RESULT: Connectivity to the module is lost.

If you then click the Enable button a second time or set the
Webpage Auto Update parameter in the Configuration => General tab to a few
seconds, then the display will include the entire spectrum.
9. Either set the Webpage Auto Update parameter in the Configuration => General
tab to a few seconds or repeatedly click the Enable button.
RESULT: The module enters the scan mode.
