Deploying the Access Point in a Wireless Network
After you have mounted the AP, follow these steps to deploy it in a wireless network:
Procedure
Step 1
Connect the power supply and power up the AP.
Step 2 Observe the AP's LED.
For LED descriptions, see
a) When you power up the AP, it begins a power-up sequence that you can verify by observing the AP's
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 AP has joined a controller, and there are no
clients associated, the LED is green or blue when clients are associated with it.
b) If the LED is not on, the AP is most likely not receiving power.
c) If the LED blinks sequentially for more than five minutes, the AP could not find its primary, secondary,
and tertiary controller. Check the connection between the AP and the controller, and be sure the AP and
the controller are either on the same subnet or that the AP has a route back to its primary, secondary, and
tertiary controller. If the AP is not on the same subnet as the controller, be sure that there is a properly
configured DHCP server on the same subnet as the AP. See
for additional information.
Step 3
Reconfigure the controller so that it is not the primary controller.

to do so, you must configure your DNS to return controller IP addresses in response to
CISCO-CAPWAP-CONTROLLER.localdomain, where localdomain is the AP domain name. Configuring
the CISCO-CAPWAP-CONTROLLER provides backward compatibility in an existing customer
deployment. When an AP receives an IP address and DNS information from a DHCP server, it contacts
the DNS to resolve CISCO-CAPWAP-CONTROLLER.localdomain. When the DNS sends a list of
controller IP addresses, the AP sends discovery requests to the controllers.
