Safety Considerations - Cisco AIR-WLC2106-K9 - Wireless LAN Controller 2106 Quick Start Manual

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. Statement 1024
Warning 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.
