In order to best use this guide, you should have already designed the wireless topology of your
network. Because the radio resource management (RRM) feature automatically detects and configures
access points as they appear on the network, it is not necessary to have any access points on the
network to install and configure a controller.
Two versions of the 4400 series controller are available: 4402 and 4404 series controllers. Cisco 4402
controllers have two gigabit Ethernet distribution system ports, each of which is capable of managing
up to 48 access points. However, Cisco recommends no more than 25 access points per port due to
bandwidth constraints. The 4402-25 and 4402-50 models allow a total of 25 or 50 access points to
join the controller. Cisco 4404 controllers have four gigabit Ethernet distribution system ports, each
of which is capable of managing up to 48 access points. However, Cisco recommends no more than 25
access points per port due to bandwidth constraints. The 4404-25, 4404-50, and 4404-100 models
allow a total of 25, 50, or 100 access points to join the controller.
Figure 1 shows the front panel layout of the 4400 series controller.
