Cisco Cisco 2106 Wireless LAN Controller Guide De Montage

If the link does not activate, check the cable. When you are connecting to a hub or a switch, 
use a straight-through cable.

After you have configured the controller, use Category-5, Category-5e, Category-6, or Category-7 
Ethernet cables to connect up to 6, 12, or 25 Cisco lightweight access points (on Cisco 2106, 2112, or 
2125 Wireless LAN Controller) to the network (distribution system) as shown in Figure 5. The 
controller has an auto MDI feature, so you can use an MDI-X or MDI cable (crossover or 
straight-through) to make the connections.

As soon as the controller is operational, the controller is available to connect access that are scanning 
for a controller. When it detects an access point, it records the access point MAC address in its 
database. The controller radio resource management (RRM) feature automatically configures the 
access point to start transmitting and allowing clients to associate.

You have prepared the controller for basic operation. Refer to the Cisco Wireless LAN Controller 
Configuration Guide for information on configuring the controller to meet the specific needs of your 
wireless network.
