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 information 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.

Technical Assistance Center
The Cisco TAC is available to all customers who need technical assistance with a Cisco product,
technology, or solution. Two types of support are available: the Cisco TAC website and the Cisco TAC
Escalation Center. The type of support that you choose depends on the priority of the problem and the
conditions stated in service contracts, when applicable.
We categorize Cisco TAC inquiries according to urgency:
• Priority level 4 (P4)—You need information or assistance concerning Cisco product capabilities,
product installation, or basic product configuration. There is little or no impact to your business
operations.
• Priority level 3 (P3)—Operational performance of the network is impaired, but most business
operations remain functional. You and Cisco are willing to commit resources during normal business
hours to restore service to satisfactory levels.
• Priority level 2 (P2)—Operation of an existing network is severely degraded, or significant aspects
of your business operations are negatively impacted by inadequate performance of Cisco products.
You and Cisco will commit full-time resources during normal business hours to resolve the situation.
• Priority level 1 (P1)—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.

Overview
Cisco Aironet 1240AG Series Access Points combine mobility and flexibility with the enterprise-class
features required by networking professionals. With a management system based on Cisco IOS software,
the 1240AG series access point is a Wi-Fi certified, wireless LAN transceiver.
The access point contains two integrated radios: a 2.4-GHz radio (IEEE 802.11g) and a 5-GHz radio
(IEEE 802.11a). You can configure the radios separately, using different settings on each.
The access point connects wireless and wired networks or is 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, uninterrupted access to the network.
You can configure and monitor the access point using the command-line interface (CLI), the
browser-based management system, Simple Network Management Protocol (SNMP), or Cisco
Structured Wireless-Aware Network (SWAN).

Hardware Features
Dual-Radio Operation
The access point supports simultaneous radio operation using a 2.4-GHz 802.11g radio and a 5-GHz
802.11a radio. Each radio uses dual-diversity integrated antennas.
The 5-GHz radio incorporates an Unlicensed National Information Infrastructure (UNII) radio
transceiver operating in the UNII 5-GHz frequency bands. The 802.11g radio is called Radio0 and the
802.11a radio is called Radio1.
Note In Cisco IOS Release 12.3(4)JA and later, the access point radios are disabled by default, and there is no
default SSID. You must create an SSID and enable the radios before the access point allows wireless
associations from other devices.

LEDs
Power Sources
Hardware Features
Draft 1A - CISCO CONFIDENTIAL
The access point has three LEDs (see Figure 1-2) to indicate Ethernet activity, radio activity, and status
indications (refer to the “Checking the Access Point LEDs” section on page 6-2 for additional
information).
• The Status LED provides general operating status and error indications.
• The Ethernet LED signals Ethernet traffic on the wired Ethernet LAN and provides Ethernet error
indications.
• The Radio LED signals that wireless packets are being transmitted or received over the radio
interface and provides radio error indications.
The access point can receive power from an external power module or from inline power using the
Ethernet cable. The access point supports the IEEE 802.3af inline power standard and Cisco CDP Power
Negotiation. Using inline power, you do not need to run a power cord to the access point because power
is supplied over the Ethernet cable.
Warning
Caution Be careful when handling the access point; the bottom plate might be hot.
This product must be connected to a Power over Ethernet (PoE) IEEE 802.3af compliant power source
or an IEC60950 compliant limited power source.
Statement 353
The access point supports the following power sources:
• Power module
• Inline power:
–
Cisco Aironet Power Injector (AIR-PWRINJ3 or AIR-PWRINJ-FIB)
–
An inline power capable switch, such as the Cisco Catalyst 3550 PWR XL, 3560-48PS,
3570-48PS, 4500 with 802.3AF PoE module, or the 6500 with 802.3AF PoE module
–
Other inline power switches supporting the IEEE 802.3af inline power standard
Note Some switches and patch panels might not provide enough power to operate the access point with both
2.4-GHz and 5-GHz radios. At power-up, if the access point is unable to determine that the power source
can supply sufficient power, the access point automatically deactivates both radios to prevent an
over-current condition. The access point also activates a Status LED low power error indication and
creates an error log entry (refer to the “Checking the Access Point LEDs” section on page 6-2 and the
“Low Power Condition” section on page 6-6).

Network Configuration Examples
Draft 1A - CISCO CONFIDENTIAL
Network Configuration Examples
This section describes the access point’s role in three common wireless network configurations. The
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.
Root Unit on a Wired LAN
An access point connected directly to a wired LAN provides a connection point for wireless users. If
more than one 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. Figure 1-6 shows access points acting as root units on a
wired LAN.

Repeater Unit that Extends Wireless Range
An 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 1-7 shows an 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.

Central Unit in an All-Wireless Network
In an all-wireless network, an access point acts as a stand-alone root unit. The 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 1-8
shows an access point in an all-wireless network.
