Cisco 4100 Series Wireless LAN Controllers

The Cisco 4100 Series Wireless LAN Controllers are part of the Cisco WLAN 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.
The

and the place of the Cisco 4100 Series Wireless LAN Controller in that system. 
The following figure 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 connec-
tion to a network through an 850nM (SX) fiber-optic link using an LC physical connector. 

Cisco 4100 Series Wireless LAN 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 GigE (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 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.

Cisco 4400 Series Wireless LAN Controllers

Cisco 4400 Series Wireless LAN Controllers are part of the Cisco WLAN Solution. Each Cisco 4400 Series 
Wireless LAN Controller controls up to 100 Cisco 1000 Series lightweight access points, making it ideal 
for large-sized enterprises and large-density applications.

The 4402 Cisco 4400 Series Wireless LAN Controller has one set of two redundant front-panel SX/LC/T 
SFP modules (SFP transceiver, or Small Form-factor Plug-in), and the 4404 Cisco 4400 Series Wireless 
LAN Controller has two sets of two redundant front-panel SX/LC/T SFP modules:

•

1000BASE-SX SFP modules provide a 1000 Mbps wired connection to a network through an 
850nM (SX) fiber-optic link using an LC physical connector. 

•

1000BASE-LX SFP modules provide a 1000 Mbps wired connection to a network through a 
1300nM (LX/LH) fiber-optic link using an LC physical connector. 

•

1000BASE-T SFP modules provide a 1000 Mbps wired connection to a network through a 
copper link using an RJ-45 physical connector. 

The one or two sets of redundant GigE connections on the Cisco 4400 Series Wireless LAN Controller 
allow the Cisco 4400 Series Wireless LAN Controller to bypass single network failures. At any given time 
one of the Cisco 4400 Series Wireless LAN Controller GigE connections is active and the other is
