Quick Start Guide: Cisco 521 Wireless Express Access Point
Read This First
This guide will help you to install a Cisco 521 Wireless Express Access Point
(hereafter referred to as the AP521) in your Smart Business Communications
System network.
How to Open the Top Cover
The top cover provides access to the cable and power connections.
Caution Do not open the access point top cover as you would a hatch or
door. You could damage the cover by doing so. An instruction
label is attached to the access point. Take time to read the label
before you open the access point cover.
When you become familiar with the opening procedure, we recommend that
you remove the label and put it in a safe place such as inside the cover of this
guide.
Note Status LED indications are not visible when the top cover is open.

Safety Information
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 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 guide will result in user exposure substantially below the FCC
recommended limits.
•Do not hold any component containing a radio such that the antenna is
very close to or touching any exposed parts of the body, especially the
face or eyes, while transmitting.
•The use of wireless devices in hazardous locations is limited to the
constraints posed by the safety directors of such environments.
Warnings
Warning
This product must be connected to a Power-over-Ethernet
(PoE) IEEE 802.3af compliant power source or an IEC60950
compliant limited power source.

Warning
In order to comply with FCC radio frequency (RF) exposure
limits, antennas should be located a minimum of 7.9 in. (20 cm)
or more from the body of all persons.
Warning
Do not operate your wireless network device near unshielded
blasting caps or in an explosive environment unless the
device has been modified to be especially qualified for such
use.
Warning
Do not work on the system or connect or disconnect cables
during periods of lightning activity.
Warning
Read the installation instructions before you connect the
system to its power source.

short-circuit (overcurrent) protection. Ensure that the
protective device is rated not greater than: 20A.
Overview
The Cisco 521 Wireless Express Access Point is a single-band 802.11g access
point that features business-class management, security, and scalability. The
access point offers high performance wireless connectivity in carpeted offices
and similar environments.
The access point is part of the Cisco Mobility Express Solution that brings
together the AP521 and the Cisco 526 Wireless Express Mobility Controller
(hereafter referred to as the WLC526). The Cisco Mobility Express Solution
is the wireless component of the Cisco Smart Business Communication
System.
The AP521 is available in two configurations:
•Standalone mode—AP521s are directly connected to the wired
infrastructure and provide high-speed wireless connectivity to users in
the areas they cover. Standalone AP521s are also known as autonomous
access points because configuration and management is performed
locally at the individual access point level.
7
Quick Start Guide: Cisco 521 Wireless Express Access Point
•Controller-based mode—AP521s associate with a WLC526 wireless
controller to provide wireless connectivity. Controller-based AP521s are
also known as lightweight access points because configuration and
management are performed through a single interface.
You configure the access points using the Cisco Configuration Assistant
(CCA). The CCA is GUI-based software that you install on a windows-based
PC and that allows you to configure all components of your Cisco Smart
Business Communications System.
The following illustration shows all the components of the Cisco Smart
Business Communications System.
The following illustration shows the AP521 and identifies its features.
