5 Configurations

The 702W series access point contains two simultaneous dual-band radios, the 2.4 GHz and 5 GHz 802.11n MIMO radios, in a controller-based mode.

The 702W series access point configuration is AIR-CAP702W-x-K9—two 2.4 GHz/5 GHz dual-band radios, with two integrated dual-band antennas.

For information on the regulatory domains (shown as “x” in the model numbers) see “Regulatory Domains” section on page 5.

Internal Antennas

The 702W model access points are configured with two dual-band antennas (two 2.4 GHz and two 5 GHz). The two antennas, deployed inside the access point, are inside the top housing. The basic features are as follows:

•Dual-Band antennas.

•Antenna elements integrated into 702W access point top housing.

•Peak gains are approximately 2 dBi in the 2.4 GHz band and 4 dBi in the 5 GHz band.

Regulatory Domains

The 702W series supports the following regulatory domains (shown as “x” in the model numbers):

• -A, -C, -D, -E, -H, -I, -K, -N, -Q, -R, -S, -T, -UX, -Z

The 702W series models that support the universal regulatory domain, have the following model number format:

• AIR-AP702W-UXK9

7 Configuring 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. This guide is available on Cisco.com.

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, interoperable 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.

Customers who have Layer 2 deployments should note that CAPWAP is not supported on Layer 2 as the CAPWAP packets are routed through Layer 3 only.

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.

Note For additional information about the discovery process and CAPWAP, see the Cisco Wireless LAN Controller Software Configuration Guide. This document is available on Cisco.com.

Note CAPWAP support is provided in controller software release 5.2 or later. However, your controller must be running release 8.0.x.x or later to support 702W series access points.

Note Make sure that the controller is set to the current time. If the controller is set to a time that has already occurred, the access point might not join the controller because its certificate may not be valid for that time.

Access points must discovered a controller before they can become an active part of the network. The access point supports these controller discovery processes:

•Layer 3 CAPWAP discovery—The access point performs a local broadcast (255.255.255.255) discovery request to find any contollers on the same subnet/vlan. The request can be forwarded to other networks by the IP helper featuer that is present on switches and router.

•Locally stored controller IP address discovery—If the access point was previously joined to a controller, the IP addresses of the primary, secondary, and tertiary controllers are stored in the access point’s non-volatile memory. This process of storing controller IP addresses on an access point for later deployment is called priming the access point. For more information about priming, see the “Performing a Pre-Installation Configuration” section on page 11.

•DHCP server discovery—This feature uses DHCP option 43 to provide controller IP addresses to the access points. Cisco switches support a DHCP server option that is typically used for this capability. For more information about DHCP option 43, see the “Configuring DHCP Option 43 and DHCP Option 60” section on page 29.

•DNS discovery—The access point can discover controllers through your domain name server (DNS). For the access point to do so, you must configure your DNS to return controller IP addresses in response to CISCO-CAPWAP-CONTROLLER.localdomain, where localdomain is the access point domain name. Configuring the CISCO-CAPWAP-CONTROLLER provides backwards compatibility in an existing customer deployment. When an access point receives an IP address and DNS information from a DHCP server, it contacts the DNS to resolve CISCO-CAPWAP-CONTROLLER.localdomain. When the DNS sends a list of controller IP addresses, the access point sends discovery requests to the controllers.

Preparing the Access Point

Before you mount and deploy your access point, we recommend that you perform a site survey (or use the site planning tool) to determine the best location to install your access point.

You should have the following information about your wireless network available:

•Access point locations

•Access point mounting options (Wall mount only)

•Access point power options: power supplied by the recommended external power supply (with power adapter AIR-PWR-C=), a DC power supply, PoE from a network device (802.3af/at), or a PoE power injector/hub (the Cisco-recommended injector is the AIR-PWRINJ4=), usually located in a wiring closet.

Note PoE-Out is available on via LAN port 4
