Warning
This equipment must be grounded. Never defeat the ground conductor or operate the 
equipment in the absence of a suitably installed ground conductor. Contact the 
appropriate electrical inspection authority or an electrician if you are uncertain that 
suitable grounding is available.

Ultimate disposal of this product should be handled according to all national laws and 
regulations. 
Statement 1040
Safety Considerations
Verify that the ambient temperature remains between 32 to 104° F (0 to 40° C), taking into 
account the elevated temperatures when installed in a rack or enclosed space.
When multiple Cisco 2100 series controllers are mounted in an equipment rack, be sure that the 
power source is sufficiently rated to safely run all the equipment in the rack (input: 100–240VAC, 
50/60 Hz, output: 48VDC, 2.08A per controller).
Verify the integrity of the electrical ground before installing the controller.
Introduction to the Controller
The Cisco 2100 Series Wireless LAN Controller works in conjunction with Cisco lightweight access 
points and the Cisco Wireless Control System (WCS) to provide system-wide wireless LAN functions. 
As a component of the Cisco Unified Wireless Network, the Cisco 2100 Series 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.
Cisco 2100 series controllers have eight 10/100 copper Ethernet distribution system ports through 
which the controller can support up to 6, 12, or 25 access points (2106, 2112, or 2125 models).
In order to best use this guide, you should have already designed the wireless topology of your network 
and have a working knowledge of how controllers function in a wireless LAN network.
Figure 1 shows a typical Cisco 2100 Series Wireless LAN Controller network topology and network 
connections, showing the medium dependent interface (MDI) Ethernet cables required. The controller 
has an auto MDI feature, so you can use straight-through or crossover cables.
