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.

Overview
Cisco Aironet 1250AG Series Access Points combine mobility, flexibility, and modularity with the
enterprise-class features required by networking professionals. With a management system based on
Cisco IOS software software, the 1250AG series access point is a Wi-Fi certified, wireless LAN
transceiver.
The access point supports two radio modules: a 2.4-GHz radio (IEEE 802.11b/g) and a 5-GHz radio
(IEEE 802.11a). The modular design enables support for a future IEEE802.11n radio module once the
standard is ratified. This modularity helps customers future proof their access point investments.
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).

Chapter1 Overview
Hardware Features
Single or Dual-Radio Operation
The access point supports single or simultaneous dual radio operation using 2.4-GHz 802.11b/g radio
and 5-GHz 802.11a radio modules. Each radio uses dual-diversity integrated antennas. A blank module
is supported for single radio access point configurations.
The access point supports upgrading of a radio module with a 802.11n radio module (future availability).
The 802.11n radio module will be available when the standard is ratified.
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.
NoteIn Cisco IOS Release 12.3(8)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.
Antennas Supported
