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).

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.

Ethernet Port
The auto-sensing Ethernet port (see Figure 1-2) accepts an RJ-45 connector, linking the access point to
your 10BASE-T or 100BASE-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 -vii).
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.

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 radio 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
Caution
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
Be careful when handling the access point; the bottom plate might be hot.
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
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.

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. After you observe all three LEDs turning green
to indicate the starting of the IOS operating system, the Status LED blinks green signifying that IOS is
operational. When in an operational status, the Ethernet LED is steady green when no traffic is being
passed and dark during periods when traffic is being passed. The sequence takes about 1 minute to
complete. Refer to Chapter 6, “Troubleshooting,” for LED descriptions.
When the sequence is complete, you are ready to obtain the access point’s IP address and perform an
initial configuration. Refer to Chapter 3, “Configuring the Access Point for the First Time.” for
instructions on assigning basic settings to the access point.

Configuring the Access Point for the First Time
Before You Start
Draft 1A - CISCO CONFIDENTIAL
Before You Start
Before you install the access point, make sure you are using a computer connected to the same network
as the access point, and obtain the following information from your network administrator:
•
A system name for the access point
•
The case-sensitive wireless service set identifiers (SSIDs) for your 802.11g and 02.11a radio
networks
•
If not connected to a DHCP server, a unique IP address for your access point (such as 172.17.25.115)
•
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)
•
If you plan on using the Cisco IP Setup Utility (IPSU) to find or assign the access point IP address,
the MAC address from the label on the bottom of the access point (such as 00164625854c)
Resetting the Access Point to Default Settings
Using the Mode Button
If you need to start over during the initial setup process, follow these steps to reset the access point to
factory default settings using the access point MODE button:
Step 1
Disconnect power (the power jack for external power or the Ethernet cable for in-line power) from the
access point.
Step 2
Press and hold the MODE button while you reconnect power to the access point until the Ethernet LED
turns an amber color, approximately 2 to 3 seconds, and release the button. All access point settings
return to factory defaults.
Using the Web-Browser Interface
Prior to using the web-browser interface, you must have the access point IP address (see the “Obtaining
and Assigning an IP Address” section on page 3-3).
Follow these steps to return to default settings using the web-browser interface:
Step 1
Open your web-browser.
Note
The access point web-browser interface is fully compatible with Microsoft Internet Explorer

Default IP Address Behavior
When you connect a 1240 series access point running Cisco IOS Release 12.3(4)JA or later software with
a default configuration to your LAN, the access point requests an IP address from your DHCP server
and, if it does not receive an IP address, continues to send requests indefinitely.
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:
Note
The access point does not have a default IP address.
•
To assign a static IP address to the access point, connect to the access point console port (see the
“Connecting to the Access Point Locally” section on page 3-4) and follow the steps in the
“Assigning an IP Address Using the CLI” section on page 3-14.
•
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 a Cisco IOS CLI command to display the IP
address, such as show interface bvi1. Follow the steps in the “Connecting to the Access Point
Locally” section on page 3-4 to connect to the console port.
– Provide your organization’s network administrator with your access point’s Media Access
Control (MAC) address. Your network administrator will query the DHCP server using the
MAC address to identify the IP address. The access point’s MAC address is on label attached to
the bottom of the access point.
– Use CLI and the serial port to identify the assigned IP address (refer to the “Finding the IP
Address Using the CLI” section on page 3-13).

Configuring the Access Point for the First Time
Configuring Basic Security Settings
Draft 1A - CISCO CONFIDENTIAL
Understanding Express Security Settings
When the access point configuration is at factory defaults, the first SSID that you create by using the
Express Security page overwrites the default SSID (tsunami), which has no security settings. The SSIDs
that you create appear in the SSID table at the bottom of the page. You can create up to 16 SSIDs on the
access point.
Note
In Cisco IOS Release 12.3(4)JA or later, there is no default SSID. You must configure an SSID before
client devices can associate to the access point.
Using VLANs
If you use VLANs on your wireless LAN and assign SSIDs to VLANs, you can create multiple SSIDs
by using any of the four security settings on the Express Security page. However, if you do not use
VLANs on your wireless LAN, the security options that you can assign to SSIDs are limited because on
the Express Security page encryption settings and authentication types are linked. Without VLANs,
encryption settings (WEP and ciphers) apply to an interface, such as the radio, and you cannot use more
than one encryption setting on an interface. For example, when you create an SSID with static WEP with
VLANs disabled, you cannot create additional SSIDs with WPA authentication because they use
different encryption settings. If you find that the security setting for an SSID conflicts with another
SSID, you can delete one or more SSIDs to eliminate the conflict.
If any VLANs are defined on the access point, the trunk port on the switch must be limited to allow only
the VLANs defined on the access point.
Express Security Types
Table 3-2 describes the four security types that you can assign to an SSID.
Table 3-2
Security Types on Express Security Setup Page

Description
Security Features Enabled
No Security
This is the least secure option. You should
use this option only for SSIDs used in a
public space and assign it to a VLAN that
restricts access to your network.
None.
Static WEP Key
This option is more secure than no security.
However, static WEP keys are vulnerable to
attack. If you configure this setting, you
should consider limiting association to the
bridge based on MAC address (refer to the
Cisco IOS Software Configuration Guide
for Cisco Aironet Access Points).
Mandatory WEP. Client devices
cannot associate using this SSID
without a WEP key that matches
the bridge’s key.

provides dynamic encryption keys, you do
not need to enter a WEP key.

IP traffic with stronger algorithms than
those used in WEP. As with EAP
authentication, you must enter the IP
address and shared secret for an
authentication server on your network
(server authentication port 1645).

Express Security Limitations
Because the Express Security page is designed for simple configuration of basic security, the options
available are a subset of the bridge’s security capabilities. Keep these limitations in mind when using the
Express Security page:
Note
•
If the No VLAN option is selected, the static WEP key can be configured once. If you select Enable
VLAN, the static WEP key should be disabled.
•
You cannot edit SSIDs. However, you can delete SSIDs and re-create them.
•
You cannot assign SSIDs to specific radio interfaces. The SSIDs that you create are enabled on all
radio interfaces. To assign SSIDs to specific radio interfaces, use the Security SSID Manager page.
•
You cannot configure multiple authentication servers. To configure multiple authentication servers,
use the Security Server Manager page.
•
You cannot configure multiple WEP keys. To configure multiple WEP keys, use the Security
Encryption Manager page.
•
You cannot assign an SSID to a VLAN that is already configured on the bridge. To assign an SSID
to an existing VLAN, use the Security SSID Manager page.
•
You cannot configure combinations of authentication types on the same SSID (for example, MAC
address authentication and EAP authentication). To configure combinations of authentication types,
use the Security SSID Manager page.
For detailed information about security and security settings, refer to the Cisco IOS Software
Configuration Guide for Cisco Aironet Access Points.

Configuring the Access Point for the First Time
Finding the IP Address Using the CLI
Draft 1A - CISCO CONFIDENTIAL
Using the Express Security Page
Follow these steps to create an SSID using the Express Security page:
Step 1
Type the SSID in the SSID entry field. The SSID can contain up to 32 alphanumeric characters.
Note
These characters are not allowed in the SSID: ?, ", $, [, \, ], and +. In addition, these characters
cannot be the first character: !, #, and ;.
Step 2
To broadcast the SSID in the bridge beacon, check the Broadcast SSID in Beacon check box. When you
broadcast the SSID, devices that do not specify an SSID can associate to the bridge. This is a useful
option for an SSID used by guests or by client devices in a public space. If you do not broadcast the
SSID, client devices cannot associate to the bridge unless their SSID matches this SSID. Only one SSID
can be included in the bridge beacon.
Step 3
(Optional) Check the Enable VLAN ID check box and enter a VLAN number (1 through 4095) to assign
the SSID to a VLAN. You cannot assign an SSID to an existing VLAN.
Step 4
(Optional) Check the Native VLAN check box to mark the VLAN as the native VLAN.
Step 5
Select the security setting for the SSID. The settings are listed in order of robustness, from No Security
to WPA, which is the most secure setting.
•
If you select Static WEP Key, choose the key number and encryption key size and enter the
encryption key (10 hexidecimal characters for 40-bit keys or 26 hexidecimal characters for 128-bit
keys).
•
If you select EAP Authentication or WPA, enter the IP address and shared secret for the
authentication server on your network.
Note
Step 6
If you do not use VLANs on your wireless LAN, the security options that you can assign to
multiple SSIDs are limited. Refer to the Cisco IOS Software Configuration Guide for Cisco
Aironet Access Points for VLAN details.
Click Apply. The SSID appears in the SSID table at the bottom of the page.
Finding the IP Address Using the CLI
When you connect the access point to the wired LAN, the access point links to the network using a bridge
virtual interface (BVI) that it creates automatically. Instead of tracking separate IP addresses for the
access point’s Ethernet and radio ports, the network uses the BVI.
To find the IP address of your access point using the console port, you can use the Cisco IOS CLI show
ip interface brief bvi1 from the privileged EXEC mode. For additional information on the CLI, refer to
the“Using the Command-Line Interface” section on page 5-1.

Cisco IOS Command Modes
Draft 1A - CISCO CONFIDENTIAL
Cisco IOS Command Modes
The Cisco IOS user interface is divided into many different modes. The commands available to you
depend on the mode you are currently using. Enter a question mark (?) at the system prompt to obtain a
list of commands available for each command mode. Refer to the Cisco IOS Command Reference for
Cisco Aironet Access Points and Bridges for a list of the supported Cisco IOS commands.
When you start a session on the access point, you begin in user mode, often called user EXEC mode.
Only a limited subset of the commands are available in user EXEC mode. For example, most of the user
EXEC commands are one-time commands, such as show commands, which show the current
configuration status, and clear commands, which clear counters or interfaces. The user EXEC
commands are not saved when the access point reboots.
To have access to all commands, you must enter privileged EXEC mode. Normally, you must enter a
password to enter privileged EXEC mode. You must enter privileged EXEC mode before you can enter
the global configuration mode.
Using the configuration modes (global, interface, and line), you can make changes to the running
configuration. If you save the configuration, these commands are stored and used when the access point
reboots. To access the various configuration modes, you must start at global configuration mode.
Table 5-1 describes the main command modes, how to access each one, the prompt you see in that mode, how
to exit the mode, and how to use the mode. The examples in the table use the host name ap.

Using the Command-Line Interface
Using no and default Forms of Commands
Draft 1A - CISCO CONFIDENTIAL
Using no and default Forms of Commands
Most configuration commands also have a no form. In general, use the no form to disable a feature or
function or reverse the action of a command. For example, the no shutdown interface configuration
command reverses the shutdown of an interface. Use the command without the keyword no to re-enable
a disabled feature or to enable a feature that is disabled by default.
Configuration commands can also have a default form. The default form of a command returns the
command setting to its default. Most commands are disabled by default, so the default form is the same
as the no form. However, some commands are enabled by default and have variables set to certain default
values. In these cases, the default command enables the command and sets variables to their default
values.

Searching and Filtering Output of show and more Commands
You can search and filter the output for show and more commands. This is useful when you need to sort
through large amounts of output or if you want to exclude output that you do not need to see.
To use this functionality, enter a show or more command followed by the pipe character (|), one of the
keywords begin, include, or exclude, and an expression that you want to search for or filter out:
command | {begin | include | exclude} regular-expression
Expressions are case sensitive. For example, if you enter | exclude protocol the lines that contain
protocol are not displayed, but the lines that contain Protocol are displayed.
This example shows how to include in the output display only lines where the expression protocol
appears:

Accessing the CLI
Draft 1A - CISCO CONFIDENTIAL
Accessing the CLI
You can open the access point’s CLI using Telnet or Secure Shell (SSH).
Opening the CLI with Telnet
Follow these steps to open the CLI with Telnet. These steps are for a PC running Microsoft Windows
with a Telnet terminal application. Check your PC operating instructions for detailed instructions for
your operating system.
Step 1
Choose Start > Programs > Accessories > Telnet.
If Telnet is not listed in your Accessories menu, choose Start > Run, type Telnet in the entry field, and
press Enter.
Step 2
When the Telnet window appears, click Connect and choose Remote System.
Note
In Windows 2000, the Telnet window does not contain drop-down menus. To start the Telnet
session in Windows 2000, type open followed by the access point’s IP address.
Step 3
In the Host Name field, type the access point’s IP address and click Connect.
Step 4
At the username and password prompts, enter your administrator username and password. The default
username is Cisco, and the default password is Cisco. The default enable password is also Cisco.
Usernames and passwords are case-sensitive.
Opening the CLI with Secure Shell
Secure Shell Protocol provides a secure, remote connection to networking devices set up to use it. Secure
Shell (SSH) is a software package that provides secure login sessions by encrypting the entire session.
SSH features strong cryptographic authentication, strong encryption, and integrity protection. For
detailed information on SSH, visit the homepage of SSH Communications Security, Ltd. at this URL:
http://www.ssh.com/
SSH provides more security for remote connections than Telnet by providing strong encryption when a
device is authenticated. See the Cisco IOS Software Configuration Guide for Cisco Aironet Access Points
for detailed instructions on setting up the access point for SSH access.

Checking Basic Settings
Mismatched basic settings are the most common causes of lost connectivity with wireless clients. If the
access point does not communicate with client devices, check the following areas.
Default IP Address Behavior
When you connect a 1240 series access point running Cisco IOS Release 12.3(4)JA or later software with
a default configuration to your LAN, the access point requests an IP address from your DHCP server
and, if it does not receive an IP address, continues to send requests indefinitely.

Troubleshooting
Checking Basic Settings
Draft 1A - CISCO CONFIDENTIAL
Enabling the Radio Interfaces
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 will allow wireless
associations from other devices. These changes to the default configuration improve the security of
newly installed access points. Refer to the “Configuring Basic Security Settings” section on page 3-9 for
instructions on configuring the SSID.
To enable the radio interfaces, follow these instructions:
Step 1
Use your web-browser to access your access point.
Step 2
When the Summary Status page displays, click Network Interfaces > Radio0-802.11G and the radio
status page displays.
Step 3
Click Settings and the radio settings page displays.
Step 4
Click Enable in the Enable Radio field.
Step 5
Click Apply.
Step 6
Click Radio1-802.11A and the radio status page displays.
Step 7
Repeat Steps 3 to 5.
Step 8
Close your web-browser.
SSID
Wireless clients attempting to associate with the access point must use the same SSID as the access point.
If a client device’s SSID does not match the SSID of an access point in radio range, the client device will
not associate.
Note
In Cisco IOS Release 12.3(4)JA and later, there is no default SSID. You must configure an SSID before
client devices can associate to the access point.
WEP Keys
The WEP key you use to transmit data must be set up exactly the same on your access point and any
wireless devices with which it associates. For example, if you set WEP Key 3 on your client adapter to
0987654321 and select it as the transmit key, you must also set WEP Key 3 on the access point to exactly
the same value. The access point does not need to use Key 3 as its transmit key, however.
Refer to the Cisco IOS Software Configuration Guide for Cisco Aironet Access Points for instructions
on setting the access point’s WEP keys.
Security Settings
Wireless clients attempting to authenticate with your access point must support the same security options
configured in the access point, such as EAP or LEAP, MAC address authentication, Message Integrity
Check (MIC), WEP key hashing, and 802.1X protocol versions.

Low Power Condition
Draft 1A - CISCO CONFIDENTIAL
If a wireless client is unable to authenticate with your access point, contact the system administrator for
proper security settings in the client adapter and for the client adapter driver and firmware versions that
are compatible with the access point settings.
Note
The access point MAC address that displays on the Status page in the Aironet Client Utility (ACU) is
the MAC address for the access point radio. The MAC address for the access point Ethernet port is
printed on the label on the back of the access point.
Low Power Condition
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 can be powered from the 48-VDC power module or from an in-line power source. The
access point supports the IEEE 802.3af power standard, Cisco Pre-Standard PoE protocol, and Cisco
Intelligent Power Management for in-line power sources.
For full operation, the access point requires 12.95 W of power. The power module and Cisco Aironet
power injectors are capable of supplying the required power for full operation, but some inline power
sources are not capable of supplying 12.95 W. Also, some high-power inline power sources, might not
be able to provide 12.95 W of power to all ports at the same time.
Note
An 802.3af compliant switch (Cisco or non-Cisco) is capable of supplying sufficient power for full
operation.
Note
If your access point is connected to in-line power, do not connect the power module to the access point.
Using two power sources on the access point might cause the access point to shut down to protect internal
components and might cause the switch to shut down the port to which the access point is connected. If
your access point shuts down, you must remove all power and reconnect only a single power source.
On power up, the access point is placed into low power mode (both radios are disabled), Cisco IOS
software loads and runs, and power negotiation determines if sufficient power is available. If there is
sufficient power then the radios are turned on; otherwise, the access point remains in low power mode
with the radios disabled to prevent a possible over-current condition. In low power mode, the access
point activates the Status LED low power error indication, displays a low power message on the browser
and serial interfaces, and creates an event log entry (see the “Checking the Access Point LEDs” section
on page 6-2 and “Inline Power Status Messages” section on page 6-7).

Low Power Condition
Draft 1A - CISCO CONFIDENTIAL
Intelligent Power Management
The access point requires 12.95 W of power for full power operation with both radios, but only needs
6.3 W of power when operating in low power mode with both radios disabled. To help avoid an
over-current condition with low power sources and to optimize power usage on Cisco switches, Cisco
developed Intelligent Power Management, which uses Cisco Discovery Protocol (CDP) to allow
powered devices (such as your access point) to negotiate with a Cisco switch for sufficient power.
The access point supports Intelligent Power Management and as a result of the power negotiations, the
access point will either enter full power mode or remain in low power mode with the radios disabled.
Note
Independent of the power negotiations, the access point hardware also uses the 802.3af classification
scheme to indicate the power required from the power source. However, the power source cannot report
the power available to the access point unless the power source also supports Intelligent Power
Management.
Some Cisco switches that are capable of supplying sufficient power require a software upgrade to
support Intelligent Power Management. If the software upgrade is not desired, you can configure the
access point to operate in pre-standard compatibility mode and the access point automatically enters full
power mode if these Cisco switches are detected in the received CDP ID field.
When the access point determines that sufficient power is not available for full power operation, an error
message is logged and the Status LED turns amber to indicate low power mode (see the “Checking the
Access Point LEDs” section on page 6-2 and the “Inline Power Status Messages” section on page 6-7).
Tip
If your switch is capable of supplying sufficient power for full operation but the access point remains in
low-power mode, your access point or your switch (or both) might be misconfigured (see Table 6-2 and
Table 6-3).
If your inline power source is not able to supply sufficient power for full operation, you should consider
these options:
•
Upgrade to a higher-powered switch
•
Use a Cisco Aironet power injector on the switch port
•
Use the 48-VDC power module to locally power the access point
Inline Power Status Messages
These messages are logged on the console port by the access point to report the power condition:
•
%CDP_PD-4-POWER_OK: Full Power - AC_ADAPTOR inline power source—This message
indicates the access point is using the power module and can support full-power operation.
•
%CDP_PD-4-POWER_OK: Full Power - NEGOTIATED inline power source—This message
indicates the access point is operating at full power and has successfully negotiated for 12.95 W of
power from a Cisco switch supporting Cisco Intelligent Power Management.
•
%CDP_PD-4-POWER_OK: Full Power - HIGH_POWER_CLASSIC inline power source—This
message indicates the access point is operating at full power because it has been configured for
pre-standard compatibility mode and has detected a Cisco switch that does not support Intelligent
Power Management but is able to supply sufficient power to the access point.

Note
You need to upgrade the software on the Cisco switch to support Intelligent Power
Management or configure the access point for pre-standard compatibility.
Configuring Power Using the CLI
Intelligent Power Management support is dependent on the version of software resident in the Cisco
switch that is providing power to the access point. Each Cisco switch should be upgraded to support
Intelligent Power Management. Until the software is upgraded, you can configure the access point to
operate with older switch software using the following Cisco IOS CLI command:
[no] power inline negotiation {prestandard source | injector H.H.H}
(where H.H.H is the MAC address of the switch port to which the access point is connected)
You can use this Cisco IOS CLI command to inform the access point of the following:
•
The Cisco switch does not support Intelligent Power Management but should be able to supply
sufficient power.
•
A power injector is being used to supply sufficient power and the Cisco switch does not support
Intelligent Power Management.
Refer to Table 6-2 for information on when to use this special Cisco IOS command and the
corresponding Cisco switch power command.
Caution
If the access point receives power through PoE, the output current of the power sourcing equipment
(PSE) cannot exceed 400 mA per port. The power source must comply with IEEE802.3af or IEC60950
for limited power sources.
Note
After completing your configuration changes, you must remove the serial console cable from the access
point.

or 802.11a). You should typically run the test several times over several days to obtain the best results
and to avoid temporary activity spikes.
Note
The carrier busy test is primarily used for single access points or bridge environments. For sites with
multiple access points, a site survey is typically performed to determine the best operation location and
operating frequency for the access points.
Note
All associated clients on the selected radio will be deassociated during the 6 to 8 seconds needed for the
carrier busy test.
Perform these steps to activate the carrier busy test:
Step 1
Use your web browser to access the access point browser interface.

Console Cable Pinouts
Overview
Draft 1A - CISCO CONFIDENTIAL
Overview
The access point requires a special serial cable that connects the access point serial console port (RJ-45
connector) to your PC’s COM port (DB-9 connector). This cable can be purchased from Cisco (part
number AIR-CONCAB1200) or can be built using the pinouts in this appendix.
Console Port Signals and Pinouts
Use the console RJ-45 to DB-9 serial cable to connect the access point’s console port to the COM port
of your PC running a terminal emulation program.
Note
Both the Ethernet and console ports use RJ-45 connectors. Be careful to avoid accidently connecting the
serial cable to the Ethernet port connector.
Note
After completing your configuration changes, you must remove the serial console cable from the access
point.
Table 1 lists the signals and pinouts for the console RJ-45 to DB-9 serial cable.

CCKM
Cisco Centralized Key Management. Using CCKM, authenticated client devices
can roam from one access point to another without any perceptible delay during
reassociation. An access point on your network provides wireless domain
services (WDS) and creates a cache of security credentials for CCKM-enabled
client devices on the subnet. The WDS access point's cache of credentials
dramatically reduces the time required for reassociation when a CCKM-enabled
client device roams to a new access point.
cell
