Cisco 4100 Series and 4400 Series WLCs
The Cisco 4100 Series WLCs and 4400 Series WLCs are designed for medium− to large−sized Enterprise facilities. Both series support the PoE option. You can use the PoE option to power the lightweight APs that connect to the controller. In addition, each 4400 WLC supports an optional redundant power supply in order to ensure maximum availability.
Cisco 5500 Series WLCs
The Cisco 5500 Series Wireless Controller is a highly scalable and flexible platform that enables systemwide services for mission−critical wireless in medium to large−sized enterprises and campus environments. The controller can be powered using one or two power supply units. When the controller is equipped with two power supply units, the power supplies are redundant. Either power supply continues to power the controller should the other power supply unit fail. Also, the power supplies are hot swappable; you do not need to remove power from the controller to replace a power supply. For more information on power supply to the WLC, refer to Installing a Power Supply Unit section of the Cisco 5500 Series Wireless Installation Guide.
