Follow these steps to perform the pre-installation configuration. Configure the switch to which your access point is to attach. Set the Cisco wireless LAN controller as the master so that new access points always join with it. Make sure DHCP is enabled on the network. The access point must be able to find the IP address of the controller.
For other methods, refer to the product documentation. Step 2 Apply power to the access point:. The access point is The access point can also be powered by the following optional external power sources:.
As the access point attempts to connect to the controller, the LEDs cycle through a green, red, and amber sequence, which can take up to 5 minutes.
Note If the access point remains in this mode for more than five minutes, the access point is unable to find the Master Cisco wireless LAN controller. Check the connection between the access point and the Cisco wireless LAN controller and be sure that they are on the same subnet. If the access point shuts down, check the power source. After the access point finds the Cisco wireless LAN controller, it attempts to download the new operating system code if the access point code version differs from the Cisco wireless LAN controller code version.
While this is happening, the Status LED blinks dark blue. If the operating system download is successful, the access point reboots. Step 3 Configure the access point if required. Step 4 If the pre-installation configuration is successful, the Status LED is green indicating normal operation.
Disconnect the access point and mount it at the location at which you intend to deploy it on the wireless network. Step 5 If your access point does not indicate normal operation, turn it off and repeat the pre-installation configuration. Note When you are installing a Layer 3 access point on a different subnet than the Cisco wireless LAN controller, be sure that a DHCP server is reachable from the subnet on which you will be installing the access point, and that the subnet has a route back to the Cisco wireless LAN controller.
Ensure that the route back to the primary, secondary, and tertiary wireless LAN controller allows IP packet fragments.
Finally, be sure that if address translation is used, that the access point and the Cisco wireless LAN controller have a static 1-to-1 NAT to an outside address. Port Address Translation is not supported.
Cisco Aironet P access points can be mounted in several configurations, including on a suspended ceiling, on a hard ceiling or wall, on an elecrtical or network box, and above a suspended ceiling.

When you power up the access point, it begins a power-up sequence that you can verify by observing the access point LED. If the power-up sequence is successful, the discovery and join process begins.
During this process, the LED blinks sequentially green, red, and off. When the access point has joined a controller, the LED is green if no clients are associated or blue if one or more clients are associated. If the LED is not on, the access point is most likely not receiving power.
If the LED blinks sequentially for more than 5 minutes, the access point is unable to find its primary, secondary, and tertiary Cisco wireless LAN controller. Check the connection between the access point and the Cisco wireless LAN controller, and be sure the access point and the Cisco wireless LAN controller are either on the same subnet or that the access point has a route back to its primary, secondary, and tertiary Cisco wireless LAN controller.
Also, if the access point is not on the same subnet as the Cisco wireless LAN controller, be sure that there is a properly configured DHCP server on the same subnet as the access point.
Note A Master Cisco wireless LAN controller should be used only for configuring access points and not in a working network. If you experience difficulty getting your access point installed and running, look for a solution to your problem in this guide or in additional access point documentation. These, and other documents, are available on Cisco.
Keep these guidelines in mind when you use P lightweight access points:. You can use DHCP Option 43 to provide a list of controller IP addresses to the access points, enabling them to find and join a controller. Figure 4 shows the location of the access point Status LED. Table 1 shows the access point Status LED indications for various conditions. Normal operating condition, but no wireless client associated. Normal operating condition, at least one wireless client association.
Configuration recovery in progress MODE button pushed for 2 to 3 seconds. Ethernet failure or image recovery MODE button pushed for 20 to 30 seconds. Software failure; try disconnecting and reconnecting unit power. You do not need to enable any debug commands on the controller because all of the CAPWAP error messages can be viewed from the syslog server itself. The state of the access point is not maintained on the controller until it receives a CAPWAP join request from the access point.
Therefore, it can be difficult to determine why the CAPWAP discovery request from a certain access point was rejected. In order to troubleshoot such joining problems without enabling CAPWAP debug commands on the controller, the controller collects information for all access points that send a discovery message to it and maintains information for any access points that have successfully joined it.
The controller collects all join-related information for each access point that sends a CAPWAP discovery request to the controller. Collection begins with the first discovery message received from the access point and ends with the last configuration payload sent from the controller to the access point. You can view join-related information for the following numbers of access points:.
When the controller is maintaining join-related information for the maximum number of access points, it does not collect information for any more access points. An access point sends all syslog messages to IP address If any of these conditions are met and the access point has not yet joined a controller, you can also configure a DHCP server to return a syslog server IP address to the access point using option 7 on the server.
The access point then starts sending all syslog messages to this IP address. When the access point joins a controller for the first time, the controller sends the global syslog server IP address the default is After that, the access point sends all syslog messages to this IP address until it is overridden by one of the following scenarios:. You can configure the syslog server for access points and view the access point join information only from the controller CLI.
A detailed explanation of the join process is on Cisco. This section provides declarations of conformity and regulatory information for the Cisco Aironet P Access Point. Cisco Systems, Inc. This device complies with Part 15 rules.
Operation is subject to the following two conditions:. This device may not cause harmful interference, and. This device must accept any interference received, including interference that may cause undesired operation. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a residential environment. Created by mahjouboi11 on AM.

At this time, the connection to the access point is lost. Login to the AP again. If you use the CLI, you can check this with the show version command. Make sure that the TFTP server is reachable from the access point.
Disable any firewall to see if it blocks the TFTP port udp The root directory is also called the current directory of the TFTP server. Ensure that you download the appropriate image for a particular model of the access point. Otherwise the download algorithm on the AP rejects the image and displays an error. Make sure that the access point meets the memory requirements specified for the image in the downloads page.
If there is not sufficient space in the flash to hold the Cisco IOS file, it produces an error message. During the upgrade process, a status pop-up window appears.
