About Cisco 2000 Series Wireless LAN ControllersCisco 2000 Series Wireless LAN Controllers
The Cisco 2000 Series Wireless LAN Controller is part of the Cisco SWAN. The Cisco 2000 Series
Wireless LAN Controller controls up to six Cisco 1000 Series lightweight access points, making it ideal
for smaller enterprise and low-density applications. About the Cisco Structured Wireless-Aware Network
gives a comprehensive overview of the Cisco SWAN and the place of the Cisco 2000 Series Wireless
LAN Controller in that system.
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 connec-
tors. The Cisco 2000 Series Wireless LAN Controller is shipped with four rubber mounting feet.
Cisco 4100 Series Wireless LAN ControllersCisco 4100 Series Wireless LAN Controllers
The Cisco 4100 Series Wireless LAN Controller is part of the Cisco SWAN. The Cisco 4100 Series
Wireless LAN Controller is one unit high, and communicates indirectly through the network (Appliance
Mode) with up to 12 (Model 4112), up to 24 (Model 4124), or up to 36 (Model 4136), associated Cisco
1000 Series IEEE 802.11a/b/g Lightweight Access Points, making it ideal for larger enterprise and
high-density applications.
Cisco 4100 Series Wireless LAN Controller support the Cisco SWAN as described in About the Cisco
Structured Wireless-Aware Network, which gives a comprehensive overview of the Cisco SWAN and the
place of the Cisco 4100 Series Wireless LAN Controllers in that system.
The following figure shows the Cisco 4100 Series Wireless LAN Controller, which has two redundant
front-panel SX/LC jacks.

Cisco 4100 Series Wireless LAN Controllers can be factory-ordered with a VPN/Enhanced Security
Module (Crypto Card) to support VPN, IPSec and other processor-intensive tasks, and contain two
1000BASE-SX network connectors that allow the Cisco 4100 Series Wireless LAN Controller to commu-
nicate with the network at GigE (Gigabit Ethernet) speeds. The 1000BASE-SX network connectors
provide 100/1000 Mbps wired connections to a network through 850nM (SX) fiber-optic links using LC
physical connectors.
The two redundant GigE connections on the Cisco 4100 Series Wireless LAN Controller allow the Cisco
4100 Series Wireless LAN Controller to bypass single network failures. At any given time one of the
Cisco 4100 Series Wireless LAN Controller GigE connections is active and the other is passive. Upon a
network failure, the active connection becomes passive, and the passive connection becomes active.
