Cisco 2000 Series WLCs

The Cisco 2000 Series WLC supports up to six lightweight APs, which makes it ideal for small− to medium−sized Enterprise facilities, such as branch offices. The PoE option is not supported on the 2000 Series WLC because the controller does not supply PoE. In order to use PoE to power APs, you must use a Cisco PoE injector or an external third−party PoE injector. The controller is powered by an external power supply that accepts power from an electrical outlet (100 to 240 VAC, 50 to 60 Hz).

Cisco 2100 Series WLCs

The Cisco® 2106 Wireless LAN Controller works in conjunction with Cisco lightweight access points and the Cisco Wireless Control System (WCS) in order to provide system−wide wireless LAN functions. As a component of the Cisco Unified Wireless Network, the Cisco 2106 Wireless LAN Controller presents network administrators with the visibility and control necessary to effectively and securely manage business−class WLANs and mobility services, such as voice, guest access, and location services.

The 2100 controller is powered by an external power supply that accepts power from an electrical outlet (100 to 240 VAC, 50 to 60 Hz).

Cisco 2100 series controllers have eight 10/100 copper Ethernet distribution system ports through which the controller can support up to six access points. Two of these ports (7 and 8) are Power over Ethernet (PoE) enabled and can be used to provide power directly to access points that are connected to these ports.
