THE SPECIFICATIONS AND INFORMATION REGARDING THE PRODUCTS IN THIS MANUAL ARE SUBJECT TO CHANGE WITHOUT NOTICE. ALL
STATEMENTS, INFORMATION, AND RECOMMENDATIONS IN THIS MANUAL ARE BELIEVED TO BE ACCURATE BUT ARE PRESENTED WITHOUT
WARRANTY OF ANY KIND, EXPRESS OR IMPLIED. USERS MUST TAKE FULL RESPONSIBILITY FOR THEIR APPLICATION OF ANY PRODUCTS.
THE SOFTWARE LICENSE AND LIMITED WARRANTY FOR THE ACCOMPANYING PRODUCT ARE SET FORTH IN THE INFORMATION PACKET THAT
SHIPPED WITH THE PRODUCT AND ARE INCORPORATED HEREIN BY THIS REFERENCE. IF YOU ARE UNABLE TO LOCATE THE SOFTWARE LICENSE
OR LIMITED WARRANTY, CONTACT YOUR CISCO REPRESENTATIVE FOR A COPY.
The following inform ation is for FCC compliance of Class A devices: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant
to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial
environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the instruction manual, may cause
harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be required
to correct the interference at their own expense.
The following information is for FCC compliance of Class B devices: The equipment described in this manual generates and may radiate radio-frequency energy. If it is not
installed in accordance with Cisco’s installation instructions, it may cause interference with radio and television reception. This equipment has been tested and found to
comply with the limits for a Class B digital device in accordance with the specifications in part 15 of the FCC rules. These specifications are designed to provide reasonable
protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation.
Modifying the equipment without Cisco’s written authorization may result in the equipment no longer complying with FCC requirements for Class A or Class B digital
devices. In that event, your right to use the equipment may be limited by FCC regulations, and you may be required to correct any interference to radio or television
communications at your own expense.
You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco equipment or one of its
peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures:
• Turn the television or radio antenna until the interference stops.
• Move the equipment to one side or the other of the television or radio.
• Move the equipment farther away from the television or radio.
• Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television or radio are on circuits
controlled by different circuit breakers or fuses.)
Modifications to this product not authorized by Cisco Systems, Inc. could void the FCC approval and negate your authority to operate the product.

Preface
Submitting a Service Request
Using the online TAC Service Request Tool is the fastest way to open S3 and S4 service requests. (S3 and
S4 service requests are those in which your network is minimally impaired or for which you require
product information.) After you describe your situation, the TAC Service Request Tool provides
recommended solutions. If your issue is not resolved using the recommended resources, your service
request is assigned to a Cisco engineer. The TAC Service Request Tool is located at this URL:
http://www.cisco.com/techsupport/servicerequest
For S1 or S2 service requests, or if you do not have Internet access, contact the Cisco TAC by telephone.
(S1 or S2 service requests are those in which your production network is down or severely degraded.)
Cisco engineers are assigned immediately to S1 and S2 service requests to help keep your business
operations running smoothly.
To open a service request by telephone, use one of the following numbers:
Asia-Pacific: +61 2 8446 7411
Australia: 1 800 805 227
EMEA: +32 2 704 55 55
USA: 1 800 553 2447

Definitions of Service Request Severity
To ensure that all service requests are reported in a standard format, Cisco has established severity
definitions.
Severity 1 (S1)—An existing network is “down” or there is a critical impact to your business operations.
You and Cisco will commit all necessary resources around the clock to resolve the situation.
Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your
business operations are negatively affected by inadequate performance of Cisco products. You and Cisco
will commit full-time resources during normal business hours to resolve the situation.
Severity 3 (S3)—Operational performance of the network is impaired while most business operations
remain functional. You and Cisco will commit resources during normal business hours to restore service
to satisfactory levels.
Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or
configuration. There is little or no effect on your business operations.

Cisco Aironet 1100 Series Access Point Hardware Installation Guide
OL-4309-07
Overview
The Cisco Aironet Cisco Aironet 1100 Series Access Point series access point is available in autonomous
and lightweight configurations. The autonomous access points can support standalone network
configurations with all configuration settings maintained within the access points. The lightweight
access points operate in conjunction with a Cisco wireless LAN controller with all configuration
information maintained within the controller.
Product Terminology
The following terms refer to the autonomous and lightweight products:
• The term access point describes both autonomous and lightweight products.
• The term autonomous access point describes only the autonomous product.
• The term lightweight access point describs only the lightweight product.
CHAPTER
1
• The term access point describes the product when configured to operate as an access point.
• The term bridge describes the product when configured to operate as a bridge.
Autonomous Access Points
The autonomous access point (models: AIR-AP1120B or AIR-AP1121G) (model: AIR-AP1252)
supports a management system based on Cisco IOS software. The 1100 series is a Wi-Fi certified,
wireless LAN transceiver and uses a single mini-PCI radio (IEEE 802.11b-compliant or IEEE
802.11g-compliant).
The access point serves as the connection point between wireless and wired networks or as the center
point of a stand-alone wireless network. In large installations, wireless users within radio range of an
access point can roam throughout a facility while maintaining seamless access to the network.
You can configure and monitor the access point using the command-line interface (CLI), the
browser-based management system, or Simple Network Management Protocol (SNMP).
Lightweight Access Points
The Cisco Aironet 1100 Series Lightweight Access Point (AIR-LAP1121G) is part of the Cisco
Integrated Wireless Network Solution and requires no manual configuration before being mounted. The
lightweight access point is automatically configured by a Cisco wireless LAN controller (hereafter
called a controller) using the Lightweight Access Point Protocol (LWAPP).

Chapter 1 Overview
The lightweight access point contains one integrated radio: a 2.4-GHz radio (IEEE 802.11g). Using a
controller, you can configure the radio settings.
In the Cisco Centralized Wireless LAN architecture, access points operate in the lightweight mode (as
opposed to autonomous mode). The lightweight access points associate to a controller. The controller
manages the configuration, firmware, and controls transactions such as 802.1x authentication. In
addition, all wireless traffic is tunneled through the controller.
LWAPP is an Internet Engineering Task Force (IETF) draft protocol that defines the control messaging
for setup and path authentication and run-time operations. LWAPP also defines the tunneling mechanism
for data traffic.
In an LWAPP environment, a lightweight access point discovers a controller by using LWAPP discovery
mechanisms and then sends it an LWAPP join request. The controller sends the lightweight access point
an LWAPP join response allowing the access point to join the controller. When the access point is joined,
the access point downloads its software if the versions on the access point and controller do not match.
After an access point joins a controller, you can reassign it to any controller on your network.
LWAPP secures the control communication between the lightweight access point and controller by
means of a secure key distribution, using X.509 certificates on both the access point and controller.

Hardware Features
LEDs
Chapter 1 Overview
The three LEDs on the top of the access point report Ethernet activity, association status, and radio
activity.
• The Ethernet LED signals Ethernet traffic on the wired LAN, or Ethernet infrastructure. This LED
is normally green when an Ethernet cable is connected, and blinks green when a packet is received
or transmitted over the Ethernet infrastructure. The LED is off when the Ethernet cable is not
connected.
• The status LED signals operational status. Steady green indicates that the access point is associated
with at least one wireless client. Blinking green indicates that the access point is operating normally
but is not associated with any wireless devices.
• The radio LED signals wireless traffic over the radio interface. The light is normally off, but it blinks
green whenever a packet is received or transmitted over the access point radio.
Figure 1-2 shows the three status LEDs.

Chapter 1 Overview
UL 2043 Certification
The access point is encased in a durable plastic enclosure having adequate fire resistance and low
smoke-producing characteristics suitable for operation in a building's environmental air space, such as
above suspended ceilings, in accordance with Section 300-22(c) of the NEC, and with Sections 2-128,
12-010(3) and 12-100 of the Canadian Electrical Code, Part 1, C22.1.
Caution Only the fiber-optic power injector (AIR-PWRINJ-FIB) has been tested to UL 2043 for operation in a
building’s environmental air space; no other power injectors or power modules have been tested to UL 2043
and they should not be placed in a building’s environmental air space, such as above suspended ceilings.
Anti-Theft Features
There are two methods of securing the access point to help prevent theft:
• Security cable keyhole—You can use the security cable slot to secure the access point using a
standard security cable, such as those used on laptop computers.
Network Examples with Autonomous Access Points
• Security hasp—When you mount the access point on a wall or ceiling using the mounting bracket
and the security hasp, you can lock the access point to the bracket with a padlock. Compatible
padlocks are Master Lock models 120T and 121T or equivalent.
Network Examples with Autonomous Access Points
This section describes the autonomous access point’s role in three common wireless network
configurations. The autonomous access point’s default configuration is as a root unit connected to a
wired LAN or as the central unit in an all-wireless network. The repeater role requires a specific
configuration.
The autonomous 1100 series access point supports these operating wireless modes:
• Root access point—Connected to a wired LAN and supports wireless clients.
• Repeater access point—Not connected to a wired LAN, associates to a root access point, and
supports wireless clients
• Workgroup bridge—Not connected to a wired LAN, associates to a root access point or bridge, and
supports wired network devices.

Network Examples with Autonomous Access Points
Root Unit on a Wired LAN
An autonomous access point connected directly to a wired LAN provides a connection point for wireless
users. If more than one autonomous access point is connected to the LAN, users can roam from one area
of a facility to another without losing their connection to the network. As users move out of range of one
access point, they automatically connect to the network (associate) through another access point. The
roaming process is seamless and transparent to the user. Figure 1-3 shows access points acting as root
units on a wired LAN.

Chapter 1 Overview
Repeater Unit that Extends Wireless Range
An autonomous access point can be configured as a stand-alone repeater to extend the range of your
infrastructure or to overcome an obstacle that blocks radio communication. The repeater forwards traffic
between wireless users and the wired LAN by sending packets to either another repeater or to an access
point connected to the wired LAN. The data is sent through the route that provides the best performance
for the client. Figure 1-4 shows an autonomous access point acting as a repeater. Consult the Cisco IOS
Software Configuration Guide for Cisco Aironet Access Points for instructions on setting up an access
point as a repeater.
Note Non-Cisco client devices might have difficulty communicating with repeater access points.

Network Examples with Autonomous Access Points
Central Unit in an All-Wireless Network
In an all-wireless network, an autonomous access point acts as a stand-alone root unit. The autonomous
access point is not attached to a wired LAN; it functions as a hub linking all stations together. The access
point serves as the focal point for communications, increasing the communication range of wireless
users. Figure 1-5 shows an autonomous access point in an all-wireless network.

Chapter 1 Overview
Workgroup Bridge Configuration
When configured in the workgroup bridge mode, the autonomous unit provides a wireless connection
for remote wired devices to a Cisco Aironet access point or to a Cisco Aironet bridge.
In Figure 1-6, the unit is configured in workgroup bridge mode and is associated to a Cisco Aironet
access point as a wireless client device. This configuration allows the Ethernet-enabled devices to pass
Ethernet traffic to and from the main LAN using the workgroup bridge.

Network Example with Lightweight Access Points
In Figure 1-7, the autonomous unit is configured in workgroup bridge mode and is associated to a Cisco
Aironet root bridge as a wireless bridge device. This configuration allows the Ethernet-enabled devices
pass Ethernet traffic to and from the main LAN using the workgroup bridge. The main advantage of this
configuration is that the wireless communication link can be over a longer distance than an access point
supports. Typically, an access point can communicate over approximately a 1-mile range; however, the
bridge-to-bridge wireless link can communicate over approximately a 21-mile range.

Network Example with Lightweight Access Points
The lightweight access points support Layer 3 network operation. Lightweight access points and
controllers in Layer 3 configurations use IP addresses and UDP packets, which can be routed through
large networks. Layer 3 operation is scalable and recommended by Cisco.
Figure 1-8 illustrates a typical Layer 3 network configuration containing lightweight access points.
