Cisco 2500 Series Wireless Controller Getting Started Guide
Connecting to the Network
Note The CLI automatically logs out without saving any changes after 5 minutes of inactivity. You
can set the automatic logout from 0 (never log out) to 160 minutes using the config serial
timeout command.
Connecting to the Network
Figure 13 shows the connection from the network (802.11 distribution system) to the controller. The
connection uses 10/100/1000BASE-T Ethernet (RJ-45 physical port, UTP, Category-5 or higher cable).
Always use Category-5, Category-5e, Category-6, or Category-7 Ethernet cables to connect the office
network equipment to the controller.

Note If the link does not activate, check the cable. When you are connecting to a hub or a switch, use a
straight-through cable.
Connecting Access Points
After you have configured the controller, use Category-5, Category-5e, Category-6, or Category-7
Ethernet cables to connect up to 50 Cisco lightweight access points to the controller Ethernet ports or to
the network (distribution system) as shown in Figure 14. 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.
