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 Ciscos 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 Ciscos 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.

Cisco Aironet 1240AG Series Access Point Hardware Installation Guide 1-4 OL-7293-01 Chapter 1 Overview LEDs Power Sources D r a f t 1 A - C I S C O C O N F I D E N T I A L Hardware Features 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 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 Caution Be careful when handling the access point; the bottom plate might be hot. The access point supports the following power sources:
Power module

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. Follow these steps to connect the access point to an Ethernet LAN when you are using a local power source:
Step 1 Step 2 Step 3 Step 4 Connect a Category 5 Ethernet cable to the RJ-45 Ethernet connector labeled Ethernet on the access point (see Figure 2-9). Connect the power module output connector to the access points 48-VDC power port (see Figure 2-9). Plug the other end of the Ethernet cable into an unpowered Ethernet port on your LAN network. Plug the other end of the power module into an approved 100- to 240-VAC outlet. For information on securing your access point, see the Securing the Access Point section on page 2-17. 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 points 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. Caution Be careful when handling the access point; the bottom plate might be hot. 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.

If desired, the cable security bracket can be removed prior to attaching the mounting plate to a ceiling or wall. Figure 2-10 Access Point with Mounting Plate and Cable Security Bracket 1 Mounting plate 2 Cable security bracket 3 Access point Removing the Cable Security Bracket The cable security bracket is primarily designed to help prevent someone from using the Mode button to reset the access point to default values or from using the serial console cable to access the access points CLI interface. If this security protection is not considered necessary, you can remove the cable security bracket. To remove the cable security bracket from the access point mounting plate, follow these instructions:
Step 1 Step 2 Position the mounting plate with the cable security bracket pointing down. Remove the four screws that attach the bracket to the mounting plate using a philips screw driver. OL-7293-01 Cisco Aironet 1240AG Series Access Point Hardware Installation Guide 2-15 Attaching the Access Point to the Mounting Plate D r a f t 1 A - C I S C O C O N F I D E N T I A L Attaching the Access Point to the Mounting Plate Follow these steps to attach the access point to the mounting plate:
Chapter 2 Installing the Access Point Step 1 If your mounting plate has the cable security bracket, follow these steps:
a. Connect the Ethernet cable to the access point Ethernet port or connect the power modules power cable to the access point 48-VDC connector before attaching the access point to the plate. b. Carefully feed the Ethernet or power cable through the notch on the cable security bracket and slide the access point towards the bracket. Note If your access point is connected to Ethernet in-line power, do not connect the local 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. Step 2 Line up the four keyhole clips on the mounting plate with the large ends of the keyhole-shaped holes on the access point. Note The keyhole clips on each side of the mounting plate are offset and can only be positioned in one direction onto the access point. Step 3 Step 4 Insert the mounting plate clips into the keyhole shaped holes on the access point. Slide the mounting plate towards the 5-GHz end of the access point while exerting slight pressure to force the access point and mounting plate together. You will hear a slight click when the locking detents contact the access point and locks it into place. Step 5 Attach and adjust the antenna(s) or antenna cables to the access point antenna connectors. Note The 5-GHz antennas and antenna cables have a blue dot or blue label. Connect only antennas or antenna cables with blue dots or labels to the access points 5-GHz antenna connectors. Step 6 If your access point does not have the cable security bracket, follow these steps:
a. Connect a CAT 5 Ethernet cable to the access point Ethernet port. b. If using local power, insert the power modules power cable into the access points 48-VDC power port. 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.

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 Step 2 Disconnect power (the power jack for external power or the Ethernet cable for in-line power) from the access point. 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 version 6.0 on Windows 98 and 2000 platforms and with Netscape version 7.0 on Windows 98, Windows 2000, and Solaris platforms. Note When using the access point browser interface, you should disable your browser pop-up blocker.

To return to factory default settings, click Reset to Defaults. To retain the IP address and return all other settings to factory default values, click Reset to Defaults (Except IP). 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 points Express Setup page, you must either obtain or assign the access points 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 organizations network administrator with your access points Media Access Control (MAC) address. Your network administrator will query the DHCP server using the MAC address to identify the IP address. The access points 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). OL-7293-01 Cisco Aironet 1240AG Series Access Point Hardware Installation Guide 3-3 Connecting to the Access Point Locally Chapter 3 Configuring the Access Point for the First Time D r a f t 1 A - C I S C O C O N F I D E N T I A L Connecting to the Access Point Locally If you need to configure the access point locally (without connecting the access point to a wired LAN), you can connect a PC to its console port using a DB-9 to RJ-45 serial cable. Caution Be careful when handling the access point, the bottom plate might be hot. Note After completing your configuration changes, you must remove the serial cable from the access point. Follow these steps to open the CLI by connecting to the access point console port:
Step 1 Connect a nine-pin, female DB-9 to RJ-45 serial cable to the RJ-45 console port on the access point and to the COM port on a computer. To connect to the access point console port, you should loop the cable as shown in Figure 2-9. Figure 3-1 shows the console port location. Figure 3-1 Console Port Location 1 Console port Note The Cisco part number for the DB-9 to RJ-45 serial cable is AIR-CONCAB1200. Browse to http://www.cisco.com/go/marketplace to order a serial cable. Step 2 Set up a terminal emulator on your PC to communicate with the access point. Use the following settings for the terminal emulator connection: 9600 baud, 8 data bits, no parity, 1 stop bit, and no flow control.

Because it is a radio device, the access point can communicate beyond the physical boundaries of your building. 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. For detail security information, refer to the Cisco IOS Software Configuration Guide for Cisco Aironet Access Points. OL-7293-01 Cisco Aironet 1240AG Series Access Point Hardware Installation Guide 3-9 Configuring Basic Security Settings Chapter 3 Configuring the Access Point for the First Time D r a f t 1 A - C I S C O C O N F I D E N T I A L Configuring Basic Security Settings You can use the Express Security page to create unique SSIDs and assign one of four security types to them. Figure 3-4 shows the Express Security page. Figure 3-4 Express Security Page Cisco Aironet 1240AG Series Access Point Hardware Installation Guide 3-10 OL-7293-01 Chapter 3 Configuring the Access Point for the First Time Configuring Basic Security Settings D r a f t 1 A - C I S C O C O N F I D E N T I A L 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 Security Type No Security Static WEP Key Description 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. 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). Security Features Enabled None. Mandatory WEP. Client devices cannot associate using this SSID without a WEP key that matches the bridges key. OL-7293-01 Cisco Aironet 1240AG Series Access Point Hardware Installation Guide 3-11 Configuring Basic Security Settings Chapter 3 Configuring the Access Point for the First Time D r a f t 1 A - C I S C O C O N F I D E N T I A L Table 3-2 Security Types on Express Security Setup Page (continued) Security Features Enabled Mandatory 802.1x authentication. Client devices that associate using this SSID must perform 802.1x authentication. Mandatory WPA authentication. Client devices that associate using this SSID must be WPA-capable. Description This option enables 802.1x authentication
(such as LEAP, PEAP, EAP-TLS, EAP-GTC, EAP-SIM, and others) and requires you to enter the IP address and shared secret for an authentication server on your network (server authentication port 1645). Because 802.1x authentication provides dynamic encryption keys, you do not need to enter a WEP key. Wi-Fi Protected Access (WPA) permits wireless access to users authenticated against a database through the services of an authentication server, then encrypts their 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). Security Type EAP Authentication WPA 28 Express Security Limitations Because the Express Security page is designed for simple configuration of basic security, the options available are a subset of the bridges security capabilities. Keep these limitations in mind when using the Express Security page:
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. Note For detailed information about security and security settings, refer to the Cisco IOS Software Configuration Guide for Cisco Aironet Access Points. Cisco Aironet 1240AG Series Access Point Hardware Installation Guide 3-12 OL-7293-01 Chapter 3 Configuring the Access Point for the First Time Finding the IP Address Using the CLI D r a f t 1 A - C I S C O C O N F I D E N T I A L 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 Step 3 Step 4 Step 5 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.
(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.
(Optional) Check the Native VLAN check box to mark the VLAN as the native VLAN. 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 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. Step 6 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 points 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 theUsing the Command-Line Interface section on page 5-1.

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. Table 5-1 Command Mode Summary Mode User EXEC Access Method Begin a session with your access point. Prompt ap>
Exit Method Enter logout or quit. Using This Mode Use this mode to:

Display system information Use this mode to verify commands. Use a password to protect access to this mode. Use this mode to configure parameters that apply to the entire access point. Privileged EXEC While in user EXEC mode, enter the enable command. ap#
Enter disable to exit. ap(config)#
To exit to privileged EXEC mode, enter exit or end, or press Ctrl-Z. Global configuration While in privileged EXEC mode, enter the configure command. While in global configuration mode, enter the interface command (with a specific interface). Interface configuration ap(config-if)#
To exit to global configuration mode, enter exit. To return to privileged EXEC mode, press Ctrl-Z or enter end. Use this mode to configure parameters for the Ethernet and radio interfaces. The 2.4-GHz radio is radio 0, and the 5-GHz radio is radio 1.

If you do not enter enough characters, the access point indicate an error (% Unknown command). This example shows how to enter the show configuration privileged EXEC command:
ap# show conf OL-7293-01 Cisco Aironet 1240AG Series Access Point Hardware Installation Guide 5-3 Using no and default Forms of Commands D r a f t 1 A - C I S C O C O N F I D E N T I A L Using no and default Forms of Commands Chapter 5 Using the Command-Line Interface 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. Understanding CLI Messages Table 5-3 lists some error messages that you might encounter while using the CLI to configure your access point. Table 5-3 Common CLI Error Messages Error Message
% Ambiguous command:
"show con"
Meaning You did not enter enough characters for your access point to recognize the command. How to Get Help Re-enter the command followed by a question mark (?) with a space between the command and the question mark.
% Incomplete command. You did not enter all the keywords or values required by this command.
% Invalid input detected at ^ marker. You entered the command incorrectly. The caret (^) marks the point of the error. Using Command History The possible keywords that you can enter with the command are displayed. Re-enter the command followed by a question mark (?) with a space between the command and the question mark. The possible keywords that you can enter with the command are displayed. Enter a question mark (?) to display all the commands that are available in this command mode. The possible keywords that you can enter with the command are displayed. The IOS provides a history or record of commands that you have entered. This feature is particularly useful for recalling long or complex commands or entries, including access lists. You can customize the command history feature to suit your needs as described in these sections:

The software assumes you have a terminal screen that is 80 columns wide. If you have a width other than that, use the terminal width privileged EXEC command to set the width of your terminal. Use line wrapping with the command history feature to recall and modify previous complex command entries. For information about recalling previous command entries, see the Editing Commands with Keystrokes section on page 5-6. 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:
ap# show interfaces | include protocol Vlan1 is up, line protocol is up Vlan10 is up, line protocol is down GigabitEthernet0/1 is up, line protocol is down GigabitEthernet0/2 is up, line protocol is up Cisco Aironet 1240AG Series Access Point Hardware Installation Guide 5-8 OL-7293-01 Chapter 5 Using the Command-Line Interface Accessing the CLI D r a f t 1 A - C I S C O C O N F I D E N T I A L Accessing the CLI You can open the access points 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 points IP address. Step 3 Step 4 In the Host Name field, type the access points IP address and click Connect. 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:

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. Cisco Aironet 1240AG Series Access Point Hardware Installation Guide 6-4 OL-7293-01 Chapter 6 Troubleshooting D r a f t 1 A - C I S C O C O N F I D E N T I A L Checking Basic Settings 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:
Use your web-browser to access your access point. Step 1 Step 2 When the Summary Status page displays, click Network Interfaces > Radio0-802.11G and the radio status page displays. Click Settings and the radio settings page displays. Click Enable in the Enable Radio field. Click Apply. Click Radio1-802.11A and the radio status page displays. Repeat Steps 3 to 5. Close your web-browser. Step 3 Step 4 Step 5 Step 6 Step 7 Step 8 SSID Wireless clients attempting to associate with the access point must use the same SSID as the access point. If a client devices 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 points 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. OL-7293-01 Cisco Aironet 1240AG Series Access Point Hardware Installation Guide 6-5 Low Power Condition D r a f t 1 A - C I S C O C O N F I D E N T I A L Chapter 6 Troubleshooting 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). Cisco Aironet 1240AG Series Access Point Hardware Installation Guide 6-6 OL-7293-01 Chapter 6 Troubleshooting D r a f t 1 A - C I S C O C O N F I D E N T I A L Low Power Condition 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:

The
<xxxx.xxxx.xxxx> indicates the MAC address of the switch port. 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.
