Chapter 1 Overview
Wireless LAN Controller Platforms
Cisco 2000 Series Wireless LAN Controllers
The Cisco 2000 Series Wireless LAN Controller is part of the Cisco Wireless LAN Solution. Each 2000
series controller controls up to six Cisco 1000 series lightweight access points, making it ideal for
smaller enterprises and low-density applications.
The Cisco 2000 Series Wireless LAN Controller is a slim 9.5 x 6.0 x 1.6 in. (241 x 152 x 41 mm) chassis
that can be desktop or shelf mounted. The Cisco 2000 Series Wireless LAN Controller front panel has
one POWER LED and four sets of Ethernet LAN Port status LEDs, which indicate 10 MHz or 100 MHz
connections and transmit/receive Activity for the four corresponding back-panel Ethernet LAN
connectors. The Cisco 2000 Series Wireless LAN Controller is shipped with four rubber desktop/shelf
mounting feet.
Cisco 4100 Series Wireless LAN Controllers
The Cisco 4100 Series Wireless LAN Controllers are part of the Cisco Wireless LAN Solution. Each
Cisco 4100 Series Wireless LAN Controller controls up to 36 Cisco 1000 series lightweight access
points, making it ideal for medium-sized enterprises and medium-density applications.
Figure 1-4 shows the Cisco 4100 Series Wireless LAN Controller, which has two redundant front-panel
SX/LC jacks. Note that the 1000BASE-SX circuits provides a 100/1000 Mbps wired connection to a
network through an 850nM (SX) fiber-optic link using an LC physical connector.
Figure 1-4 4100 Series Controller
The Cisco 4100 Series Wireless LAN Controller can be factory-ordered with a VPN/Enhanced Security
Module (Crypto Card) to support VPN, IPSec and other processor-intensive tasks, and contains two
(Cisco 4100 Series Wireless LAN Controller) 1000BASE-SX network connectors that allow the Cisco
4100 Series Wireless LAN Controller to communicate with the network at Gigabit Ethernet speeds. The
1000BASE-SX network connectors provides 100/1000 Mbps wired connections to a network through
850nM (SX) fiber-optic links using LC physical connectors.
The two redundant Gigabit Ethernet connections on the Cisco 4100 Series Wireless LAN Controller
allow the Cisco 4100 Series Wireless LAN Controller to bypass single network failures.
