Radio Module Operational Overview

With the module installed, the AP 3600 operates three active radios; 2.4 GHz and 5 GHz integrated
radios (slots 0 and 1) as well as the 802.11ac 5 GHz module which shows up as (slot 2). This additional
radio module takes the overall power draw of the Access Point to 18 Watts. If the power being supplied
is limited (for example 15.4W 802.3af power) the Access Point will come up with the radio module
disabled until a suitable source of power is available such as enhanced PoE, 802.3at PoE+, Power
Injector, or the Local Power Supply AIR-PWR-B.
