Marketing Information

The Cisco 4112 Wireless LAN Controller uses two redundant Gigabit Ethernet connections to bypass single network failures, and communicates with up to 12 Cisco 1000 series lightweight access points. That is, at any given time one of the Cisco 4112 Wireless LAN Controller Gigabit Ethernet connections is active and the other is passive. Upon a network failure, the active connection becomes passive, and the passive connection becomes active. Note that the 1000BASE-SX Network Adapters provide 100/1000 Mbps wired connections to a network through 850nM (SX) fiber-optic links using LC physical connectors.
