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 39 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.

10 Troubleshooting

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.com.

Keep these guidelines in mind when you use 2702 series lightweight access points:

•The access point can only communicate with Cisco wireless LAN controllers.

•The access point does not support Wireless Domain Services (WDS) and cannot communicate with

WDS devices. However, the controller provides functionality equivalent to WDS when the access

point joins it.

•CAPWAP does not support Layer 2. The access point must get an IP address and discover the

controller using Layer 3, DHCP, DNS, or IP subnet broadcast.

•The access point console port is enabled for monitoring and debug purposes. All configuration

commands are disabled when the access point is connected to a controller.
