Chapter 4 Configuring the Access Point for the First Time
Support for 802.11ac in 3600 series Access Points
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 Table 4-4 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
radi
os 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 Table 4-5 for the various power management options available.
802.11n and 802.11ac use the power levels configured o
n 802.11n. You cannot configure power levels
independently for 802.11ac.

AC adapter Yes Yes Yes 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.
802.3af Yes Yes No
