Cisco Cisco Aironet 1040 Series Access Point

The following points must be kept in mind while configuring 802.11ac radios:

The 802.11ac radio depends on the 802.11n radio to be fully functional. Shutting down the 802.11n 
radio will affect the 802.11ac functionalities.

802.11n and 802.11ac radios operate in the same band. However the channel widths can be 
independently configured with the restriction that it should be above the channel width configured 
on 802.11n. Please see 

 for more details on the supported channel width combinations.

Off channel scanning or transmissions are not supported. The 802.11ac radio depends on 802.11n 
radios for the off channel scanning functionality.

All access points except outdoor mesh products can be powered over ethernet. Access points with two 
radios powered over ethernet are fully functional and support all the features. However, with 802.11ac 
plugged in 3600 series AP, 802.3af is not a sufficient power source to support all the three radios. Please 
see 

 for the various power management options available.

802.11n and 802.11ac use the power levels configured on 802.11n. You cannot configure power levels 
independently for 802.11ac.

This is the default behavior. We are thinking of adding a scheme 
similar to how we implemented 1250 – if 2.4G is disabled then 
enable 5G 11ac.
