a DHCP server. If your network does not use a DHCP server, you must
connect to the access point’s console port and assign a static IP address (See
the “Assigning an IP Address Using the CLI” section on page 17.
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 have familiarized yourself with the opening procedure, we
recommend that you remove the label, putting 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.
Follow these steps to open the top cover:
1. Put the access point on a flat surface, and grasp it with both hands, as
shown in this illustration.

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. When used with approved Cisco Aironet antennas, Cisco Aironet
products 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.

Warning This product relies on the building’s installation for
short-circuit (overcurrent) protection. Ensure that the
protective device is rated not greater than: 20A.
Overview
This guide is designed to help you minimally configure a Cisco Aironet 521
Series Access Point using the access point graphical user interface (GUI)
through your web browser. The GUI is the primary-configuration tool. This
guide provides an overview of the access point and provides instructions for
mounting it.
Do not attempt to connect a cable with a protective boot to the access point
Ethernet or console port. Because of limited space in the connection area,
booted connectors will not fit.
Unpacking the Access Point

Complete these steps to prepare for installation.
1. Carefully unpack and remove the access point and hardware kit from the
shipping box.
2. Return all packing material to the shipping container, and save it.
3. Verify all the package contents, and inspect each item for damage. If any
item is missing or damaged, contact your Cisco representative for
support.
4. Become familiar with the access point and its features, which are
identified in this illustration.
Caution Be careful when handling the access point; the bottom plate
might be hot.

Installation Summary
Installing the access point involves these operations:
•Mounting the access point
•Connecting power
•Configuring basic settings
•Configuring security settings
Before you install the access point, make sure that you are using a computer
connected to the same network as the access point, and obtain the following
information from your network system administrator:
•TBD

Quick Start Guide Cisco Aironet 521 Access Points
If you are not connected to a DHCP server, you can assign an IP address to
the access point using the CLI. In this situation, obtain a unique IP address
for your access point, a default gateway, and subnet mask from your network
system administrator.
Mounting the Access Point
The access point uses a detachable universal mounting plate to mount the
access point to flat surfaces such as a wall or ceiling. The universal mounting
plate is also used to mount the access point to an electrical or network
junction box, or to the provided rail clips for below a suspended ceiling.
The mounting process is simple and requires common tools. Because it is
detachable, you can use the universal mounting plate to mark the positions of
the mounting holes for your installation. You then install the universal
mounting bracket on the surface and attach the access point when you are
ready.
When you have mounted the access point, its padlock post enables you to
protect the Ethernet, power cables, and Mode button, and to lock the access
point with a padlock.

Connecting Power
Connect the 521 series access point to a power source. The access point can
be powered locally by using an AC power module or over the Ethernet using
power sourcing equipment (PSE).
When power is supplied to the access point, a routine power-up sequence
begins which you can monitor by observing the access point status LED.
During the power up sequence the LED displays a series of colors. When the
power up sequence is complete, the LED displays a light green color to
indicate that it is ready for operation. When a client associates to the access
point, the status LED changes to blue. The LED displays amber to indicate a
problem, such as when the access point is unable to verify that the PSE is
supplying sufficient power. See the “Configuring Power” section on page 17.
Obtaining an IP Address
Your access point needs an IP address to operate. The access point is no
longer shipped with a default IP address. It obtains an IP address from your
network’s DHCP server when you connect the access point to your network.
If your network does not have a DHCP server, the access point continues to
request an IP address until you assign it one.

Quick Start Guide Cisco Aironet 521 Access Points
You must know your access point’s IP address before you can use the
web-based management GUI. If your access point obtained its IP address
from your network’s DHCP server, you or your network administrator can
find it by querying the DHCP server using the access point’s MAC address.
You can also find the access point’s IP address using Cisco’s IP Setup Utility
You can download IPSU from Cisco.com.
Configuring Power
After connecting the access point to a power source, its status LED might be
amber, which can indicate that the access point is unable to verify that the
PSE is supplying sufficient power. In such cases, you will need to configure
settings on the access point or the switch to identify your power source.
Configuring Basic Settings
Follow these steps to configure basic settings for the access point using the
GUI Express Setup page.

Configuring Security Settings
After you assign basic settings to your access point, you must configure
security settings to prevent unauthorized access to your network. Because it
is a radio device, the access point can communicate beyond the physical
boundaries of your work site.

panel or the Ethernet and Radio LEDs in the cable bay area. You can use the
LED colors to assess the unit status.
Note To see the Ethernet and Radio LEDs you must open the access
point cover. (Refer to the “How to Open the Top Cover” section
on page 2.)

Resetting to Default Configuration
If you forget your password that allows you to configure the access point, you
may need to completely reset the configuration. You can use the MODE
button on the access point to reset the configuration.
Note These steps reset all configuration settings to factory defaults,
including passwords, WEP keys, the IP address, and the SSID.
Using the MODE Button
Follow these steps to delete the current configuration and return all access
point settings to the factory defaults by using the MODE button:
1. Open the access point cover (refer to the “How to Open the Top Cover”
section on page 2).
2. Disconnect power from the access point (the power jack for external
power or the Ethernet cable for in-line power).
3. Press and hold the MODE button while you reconnect power to the
access point.
4. Continue pressing the MODE button until the Ethernet LED turns
amber. (approximately 2 to 3 seconds). Then release the button.
