e. If the operating system download is successful, the access point reboots.
Step3 Configure the access point if required. Use the controller CLI, controller GUI, or Cisco Prime Infrastructure to
customize the access-point-specific 802.11n network settings.
Step4 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.
Step5 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. Also be sure that the route back to the
Cisco wireless LAN controller has destination UDP ports 5246 and 5247 open for CAPWAP communications.
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.
8 Mounting the Access Point
Cisco Aironet 700 series access points can be mounted in several configurations, including on a suspended ceiling, on a hard
ceiling or wall, on an electrical or network box, and above a suspended ceiling. Click this URL to browse to complete access

9 Deploying the Access Point on the Wireless Network
After you have mounted the access point, follow these steps to deploy it on the wireless network:
Step1 Connect and power up the access point.
Step2 Observe the access point LED (for LED descriptions, see “Checking the Access Point LED” section on page 11).
a. 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 amber. When the access point has joined a controller, the LED chirps green if no clients are
associated or stays green if one or more clients are associated.
b. If the LED is not on, the access point is most likely not receiving power.
c. 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. See the “Configuring DHCP Option 43 and DHCP Option 60” section
on page 23 for additional information.
Step3 Reconfigure the Cisco wireless LAN controller so that it is not the Master.
Note A Master Cisco wireless LAN controller should be used only for configuring access points and not in a working
network.
