Introduction to the Access Point
The Cisco Aironet 1200 Series Access Point delivers a high performance, reliable, secure, and easily managed wireless LAN solution for enterprise customers and for small- and medium-sized businesses. The access point is designed to incorporate new technology enhancements as they become available.
The 1200 series access point can contain two radios: a 2.4-GHz radio in an internal mini-PCI slot and a 5-GHz radio module in an external, modified cardbus slot. The access point supports one radio of each type, but does not support two 2.4-GHz or two 5-GHz radios. You can configure the radios separately, using different settings on each radio.
The access point can be configured from the factory for single-band operation. You can field upgrade an access point preconfigured for single-radio operation using a 5-GHz radio module or a 2.4-GHz radio card. You can also order a preconfigured dual radio access point (1230AG series).
The 2.4-GHz mini-PCI radio card is available in two versions:
•IEEE 802.11b mini-PCI radio card (802.11b radio)
•IEEE 802.11g mini-PCI radio card (802.11g radio)
–Requires Cisco IOS Release 12.2 (13)JA or later
The 5-GHz radio module connects to the access point's modified card bus connector and is available in three versions:
•Low power IEEE 802.11a radio module with integrated antenna (RM20A radio module)
•Enhanced IEEE 802.11a radio module with dual integrated antennas (RM21A radio module)
–Requires Cisco IOS Release 12.3(2)JA or later
•Enhanced IEEE 802.11a radio module with dual external RP-TNC antenna connectors (RM22A radio module)
–Requires Cisco IOS Release 12.3 (2)JA or later
Tip If you are upgrading to an 802.11g radio or an RM21A or RM22A radio module, make sure you are running the correct Cisco IOS version before you install the radio or module. If your access point is running an earlier version, it will not recognize the radio or module and continually boot.
All 5-GHz radios incorporate an Unlicensed National Information Structure (UNII) radio transceiver operating in the UNII 5-GHz frequency bands. The RM20A and RM21A contain dual integrated omnidirectional antennas for diversity operation. In the graphical user interface (GUI) and the command line interface (CLI), The 802.11b or 802.11g radio is referred to as Radio0 and the 802.11a radio is referred to as Radio1.
This guide provides information about the dual-band configuration running the Cisco IOS operating system. Your access point configuration may vary depending on the configuration you ordered.
The FCC with its action in ET Docket 96-8 has adopted a safety standard for human exposure to radio frequency (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 installation of this radio according to the instructions found in this manual and the Cisco Aironet 1200 Series Access Point Hardware Installation Guide will result in user exposure that is substantially below the FCC recommended limits.
•Do not touch or move antenna(s) while the unit is transmitting or receiving.
•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 and eyes, while transmitting.
•The use of wireless devices in hazardous locations is limited to the constraints posed by the local codes, the national codes, and the safety directors of such environments.

•If the access point is not on the same subnet as your PC, a default gateway address and subnet mask
•A Simple Network Management Protocol (SNMP) community name and the SNMP file attribute (if SNMP is in use)
Note Plan to configure the access point before mounting it in a relatively inaccessible location. Some steps, such as those requiring a serial cable, are easier to perform if the access point is accessible.
Attaching and Adjusting the Antennas
The access point supports single antenna or dual diversity antennas. Two RP-TNC connectors are provided on the back of the unit for the 2.4-GHz radio.
Attach the antennas to the RP-TNC connectors on the back of the access point and hand tighten.
If you are using one antenna, attach the antenna or antenna cable to the 2.4-GHz Right/Primary RP-TNC connector.
If you are using two antennas for diversity coverage, attach the second antenna or antenna cable to the 2.4-GHz Left RP-TNC antenna connector.
If you are using a Cisco Aironet 2 dBi antenna, orient the antenna depending on how you intend to mount the access point.
•On a table or desk, orient the antenna straight up.
•On a vertical surface, such as a wall, orient the antenna straight up.
•On a ceiling, orient the antenna straight down.
If you are using another Cisco Aironet antenna, refer to the antenna mounting instructions that came with your antenna.
5-GHz Integrated Antenna
The 5-GHz integrated antenna is already installed. Deploy the antenna depending on how the access point is mounted:
•Unfold the antenna housing if the access point is mounted on a horizontal surface, such as a ceiling or desktop.
•Leave the housing in the folded position if the access point is mounted on a vertical surface, such as a wall.
5-GHz External Antenna
The access point supports an RM22A radio module for use with a single antenna or dual diversity antennas. Two RP-TNC antenna connectors are provided on the back of the module for the 5-GHz radio.
Note Be sure to connect your 5-GHz antennas to the 5-GHz radio antenna connectors. The Cisco Aironet antenna cables have a blue marker label near the antenna connector and the radio module has a corresponding label near its 5-GHz antenna connectors.
If you are using one antenna, attach the antenna or antenna cable to the 5-GHz Right/Primary RP-TNC connector and hand tighten.
If you are using two antennas for diversity coverage, attach the second antenna or antenna cable to the 5-GHz Left RP-TNC antenna connector.

Connecting to an Ethernet Network with an Inline Power Source
Follow these steps to connect the access point to the Ethernet LAN when you have an inline power source:
1. Connect the Ethernet cable to the RJ-45 Ethernet connector labeled Ethernet on the access point. Connect the other end of the cable to one of the following:
Caution Both the Ethernet and console ports use RJ-45 connectors. Be careful when connecting the Ethernet cable to avoid connecting to the console port.
a. A switch with inline power, such as a Cisco Catalyst 3550-24 PWR.
b. An inline power switch panel, such as a Cisco Catalyst Inline Power Patch Panel.
c. The end of a Cisco Aironet power injector labeled To AP/Bridge and the other end labeled To Network to the 10/100 Ethernet LAN.
Connecting to an Ethernet Network with Local Power
Follow these steps to connect the access point to an Ethernet LAN when you have a local power source:
1. Connect the Ethernet cable to the RJ-45 Ethernet connector labeled Ethernet on the access point.
Caution Both the Ethernet and console ports use RJ-45 connectors. Make sure that you connect the Ethernet cable to the Ethernet port and not to the console port.
2. Connect the power pack's power output connector to the 48-VDC power port labeled 48VDC on the access point.
3. Plug the other end of the power pack into an approved 100 to 240 VAC outlet.
Powering Up the Access Point
When power is applied to the access point, it begins a routine power-up sequence that you can monitor by observing the three LEDs on top of the access point. All three LEDs on the top of the access point (Radio, Status, and Infrastructure) slowly blink amber, red, and green in sequence; the sequence takes a couple of minutes to complete. Because the radios are disabled, the Radio LED is dark.
Note See the Cisco Aironet 1200 Series Access Point Hardware Installation Guide for a detailed description of the LED displays.
When the sequence is complete, you are ready to associate an IP address with the access point and perform an initial configuration.
Obtaining and Assigning an IP Address
To browse to the access point's Express Setup page, you must either obtain or assign the access point's IP address using one of the following methods:
•Connect to the access point console port and assign a static IP address.
•Use a DHCP server (if available) to automatically assign an IP address. You can find out the DHCP-assigned IP address using one of the following methods:
–Connect to the access point console port and use the show ip interface brief command to display the IP address.
–Query the DHCP server using the access point's MAC address to identify the IP address. Your network administrator can do this.
Using the Access Point's Console Port
You can identify or assign an IP address using the access point's console port and a terminal emulator for all operating systems. However, if your computer's operating system is Windows CE, Linux, or Mac OS, you must use the access point's command-line console.
To access the command-line console, connect a DB-9 to RJ-45 serial cable (Cisco part number AIR-CONCAB-1200) from your PC to the RS-232 console port on the access point. Then open a terminal emulator to view the express setup screen and identify the IP address. Use these port settings for the terminal session: 9600 baud, no parity, 8 data bits, 1 stop bit, and no flow control.
Caution Both the Ethernet and console ports use RJ-45 connectors. Be careful when connecting the console cable to avoid connecting to the Ethernet port.
Procedures for using the command-line console can be found in the Cisco Aironet 1200 Series Access Point Hardware Installation Guide. The guide is available on Cisco.com.
Configuring the Access Point
After you have determined or assigned the access point's IP address, you can open the access point management pages and initially configure the access point. The access point must be connected to your network and your PC must be on the same subnet. Follow these steps.
1. Open your Internet browser. You must use Microsoft Internet Explorer (version 4.0 or later) or Netscape Navigator/ Communicator (version 4.0 or later).
2. Enter the access point's IP address in the browser address line and press Enter. The Summary Status screen appears.
3. From the Summary Status screen, click Setup and Express Setup. The Express Setup screen appears.
4. Enter the configuration settings you obtained from your system administrator. The configurable settings include:
a. Host Name—The host name helps identify the access point on your network
Note When you change the host name, the access point resets the radios, causing associated clients to disassociate and quickly reassociate.
b. Configuration Server Protocol—Click the button that matches the network's method of IP address assignment: DHCP or Static IP.
c. IP Address—Use this setting to assign or change the access point's IP address. If DHCP is enabled for your network, leave this field blank.
d. IP Subnet Mask—Enter the IP subnet mask provided by your network administrator so the IP can be recognized on the LAN. If DHCP is enabled, leave this field blank.
e. Default Gateway—Enter the default gateway IP address provided by your network administrator. If DHCP is enabled, leave this field blank.
f. SNMP Community—If your network uses SNMP, enter the SNMP Community name provided by your network administrator and select the attributes of the SNMP data (also provided by your network administrator).
g. Role in Radio Network—Click the button that describes the role of the access point in your network. Select Access Point (Root) if your access point is connected to the wired LAN. Select Repeater (Non-Root) if it is not connected to the wired LAN. Select Workgroup Bridge if you desire the access point to become a workgroup bridge.
Note Configuring the access point as a workgroup bridge has restrictions. For more information, see the Cisco Aironet 1200 Series Access Point Hardware Installation Guide.
h. Optimize Radio Network for—Use this setting to select either preconfigured or customized settings for the access point radio. Throughput optimizes the data volume handled by the access point but might reduce its range. Range maximizes range but might reduce throughput. Default uses the settings shipped from Cisco. Custom uses the settings you enter on the Network Interfaces: Radio-801.11b Settings page.
i. Aironet Extensions—Enable this setting if there are only Cisco Aironet devices on your wireless LAN.
5. Click Apply or OK to save your settings. If you changed the access point's IP address, you lose your connection to the access point. Browse to the new IP address to reconnect.
Note You can restore the access point to its factory defaults by unplugging the power jack and plugging it back in while holding down the Mode button for a few seconds or until the Status LED turns amber.
Configuring Security Settings
Cisco IOS Release 12.2 (15)JA and later include an Express Security page. 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.
Just as you use the Express Setup page to assign basic settings, you can use the Express Security page to create unique SSIDs and assign one of four security types to them. The following illustration shows the Express Security page for Cisco IOS Release 12.3(2)JA.
The following table briefly describes the four security settings you can assign to an SSID using the Express Security page. In Cisco IOS Release 12.3(4)JA or later, you must assign an SSID.
Refer to the Aironet 1200 Series Access Points, Cisco IOS Release xx.x(x) for complete security information and configuration procedures.

When you assign an IP address to the access point using the CLI, you must assign the address to the BVI. Beginning in a privileged EXEC mode, follow these steps to assign an IP address to the access point's BVI:
Command Purpose Step 1
Enter global configuration mode.
Enters interface configuration mode for the BVI.
ip address address mask
Assigns an IP address and subnet mask address to the BVI.
Note If you used a Telnet session to connect to the access point, you lose your connection when you assign a new IP address to the BVI. If you need to continue configuring the access point using Telnet, use the new IP address to open another Telnet session to the access point.
Using a Telnet Session to Access the CLI
Follow these steps to browse to access the CLI using a Telnet session. These steps are for a PC running Microsoft Windows with a Telnet terminal application. Check your PC operating instructions for detailed instructions.
1. Select Start > Programs > Accessories > Telnet.
If Telnet is not listed in your Accessories menu, select Start > Run, type Telnet in the entry field, and press Enter.
2. When the Telnet window appears, click Connect and select Remote System.
3. In the Host Name field, type the access point's IP address and click Connect.
You can mount the access point on any of the following surfaces:
•Horizontal or vertical flat surfaces, such as walls or ceilings
The access point ships with a detachable mounting bracket and the necessary mounting hardware. Because it is detachable, you can use the mounting bracket as a template to mark the positions of the mounting holes for your installation. You then install the mounting bracket and attach the access point when you are ready. Refer to the following illustration to locate the various mounting holes for the method you intend to use.
If you plan to mount the access point in an area subject to environmental air space, Cisco recommends that you mount the access point horizontally so that its antennas are pointing down, which results in the access point complying with regulatory requirements for environmental air space.
