Overview
The Cisco 521 Wireless Express Autonomous Access Point (hereafter called the AAP521) is a single-band 802.11g access point that offers high-performance wireless connectivity in carpeted offices and similar environments. The AAP521 is a component of the Cisco Mobility Express Solution.
The Cisco Mobility Express Solution brings together the AAP521 and the Cisco 500 Series Wireless Express Mobility Controller to provide a cost effective wireless solution specifically designed to meet the needs of small and medium-sized businesses. The Mobility Express Solution aligns with the Cisco Smart Business Communication System-a unified communications solution that provides voice, data, video, security and wireless capabilities while integrating with existing desktop applications like calendar, e-mail and CRM to provide a complete solution.
As part of this solution, the AAP521 addresses the requirements of small and medium-sized businesses that require a traditional access point solution by operating in standalone mode. In standalone mode access points are directly connected to the wired infrastructure and provide reliable high-speed wireless connectivity to users in the area they cover. Built-in antennas provide omni-directional coverage specifically designed for open workspaces. A multipurpose mounting bracket secures the access point to ceilings and walls. For maximum concealment, the access point may be placed above ceilings or suspended ceilings. The AAP521's UL 2043 rating allows it to be placed above ceilings in plenum areas regulated by municipal fire codes.
Software Release Information
The AAP521s are factory installed with Cisco IOS Release 12.4(3g)JX.

FCC Safety Compliance Statements
The FCC, with its action in ET Docket 96-8, has adopted a safety standard for human exposure to RF electromagnetic energy emitted by FCC-certified equipment. Cisco 521 autonomous access points meet the uncontrolled environmental limits found in OET-65 and ANSI C95.1, 1991. Proper operation of this radio device according to the instructions in this document and the installation and configuration guides will result in user exposure substantially below the FCC recommended limits.

Installation Instructions
In the standalone architecture, you can deploy up to three AAP521's and configure them using the CCA. This procedure assumes that you are using a Cisco Unified Communications 500 Series , a Cisco Catalyst Express 520 switch, and the CCA.
When you create or modify an SSID for an AAP521 using the CCA, follow these guidelines:
•
•
Refer to the Quick Start Guide Cisco 521 Wireless Express Access Point for additional instructions on installing access points.
Note
Personnel installing the access points must understand wireless techniques and grounding methods. Access points with internal antennas can be installed by an experienced IT professional.
Important Notes
This section describes important information about the AAP521.
Caveats
This section lists the open caveats for the AAP521.
Open Caveats
The following caveat is open in this release:
•
When reloading an access point after a software upgrade, if the access point receives a new DHCP IP address, the CCA reports that the reload failed. The reload did not fail; the new IP address causes the access point to be unreachable because the IP address stored in the CCA does not reflect the new address.
Workaround: Ignore the message. The new DHCP address assigned to the access point after the reload the access point is "lost" as far as the CCA is concerned. Correct this situation by removing the access point referenced by the old address from the community and then add the access point as it is discovered with the new DHCP address.
•
When using the CCA to configure an AAP521 for EAP with dynamic WEP, the application selects both Open w/EAP and Network EAP. When the client associates it passes the MS-PEAP authentication via the Microsoft IAS server but cannot get a DHCP address or pass data.
Workaround: Manually set the access point to Open w/EAP only. The client is able to obtain a DHCP address and pass data.
