Powering the Access Point
The AP can be powered through only Power-over-Ethernet (PoE), using:
• 802.3at Cisco Power Injector AIR-PWRINJ6=
• Any 802.3at (25.5 W) compliant switch port

Configuring and Deploying the Access Point
This section describes how to connect the access point to a wireless LAN controller. Because the
configuration process takes place on the controller, see the Cisco Wireless LAN Controller
Configuration Guide for additional information.
The information in this section does not include configuring Link Aggregation. For information on
configuring Link Aggregation, see the Cisco Wireless LAN Controller Configuration Guide, Release
8.2, at the following URL:

The Controller Discovery Process
The access point uses standard Control and Provisioning of Wireless Access Points Protocol
(CAPWAP) to communicate between the controller and other wireless access points on the network.
CAPWAP is a standard, inter-operable protocol which enables an access controller to manage a
collection of wireless termination points. The discovery process using CAPWAP is identical to the
Lightweight Access Point Protocol (LWAPP) used with previous Cisco Aironet access points.
LWAPP-enabled access points are compatible with CAPWAP, and conversion to a CAPWAP controller
is seamless. Deployments can combine CAPWAP and LWAPP software on the controllers.
The functionality provided by the controller does not change except for customers who have Layer 2
deployments, which CAPWAP does not support.
In a CAPWAP environment, a wireless access point discovers a controller by using CAPWAP discovery
mechanisms and then sends it a CAPWAP join request. The controller sends the access point a
CAPWAP join response allowing the access point to join the controller. When the access point joins
the controller, the controller manages its configuration, firmware, control transactions, and data
transactions.
