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).

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.
Note In 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.

Chapter 1 Overview
Hardware Features
Ethernet Port
The auto-sensing Ethernet port (see Figure TBD ) accepts an RJ-45 connector, linking the access point
to your 10BASE-T, 100BASE-T, or 1000BASE-T Ethernet LAN. The access point can receive power
through the Ethernet cable from a power injector, switch, or power patch panel. The Ethernet MAC
address is printed on the label on the back of the access point (refer to the “Locating the Product Serial
Number” section on page -viii).
Console Port
The serial console port provides access to the access point’s command-line interface (CLI) using a
terminal emulator program. The port is located on the end of the unit (see Figure 1-2). Use an RJ-45 to
DB-9 serial cable to connect your computer’s COM port to the access point’s serial console port. (Refer
to Appendix E, “Console Cable Pinouts,” for a description of the console port pinouts.) Assign the
following port settings to a terminal emulator to open the management system pages: 9600 baud, 8 data
bits, no parity, 1 stop bit, and no flow control.
Note After completing your configuration changes, you must remove the serial cable from the access point.
LEDs
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 error indications.
Power Sources
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
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 1250 Series 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 6-5).
UL 2043 Certification
The access point has 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; the AIR-PWRINJ3 power injector and the power module are not
tested to UL 2043 and should not be placed in a building’s environmental air space, such as above
suspended ceilings.

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 1-4 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 1-5 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.
