Cisco Cisco Aironet 3800i Access Point Guía De Instalación

The AP can be powered using:

802.3at Cisco Power Injector AIR-PWRINJ6=.

Cisco AIR-PWR-50, which is a 100-240VAC, 48VDC, 50W power supply.

Any 802.3at (25.5 W) compliant switch port.

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 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.
