Wireless LAN Controller Platforms

Cisco 2000 Series Wireless LAN Controllers

Cisco 2000 Series Wireless LAN Controllers can communicate with the network through any one of its physical data ports, as the logical management interface can be assigned to one of the ports. The physical port description follows:

•Up to four 10/100BASE-T cables can plug into the four back-panel data ports on the Cisco 2000 Series Wireless LAN Controller chassis.

Figure 1-5shows connections to the 2000 series controller.

Cisco 4100 Series Wireless LAN Controllers

Cisco 4100 Series Wireless LAN Controllers can communicate with the network through one or two physical data ports, as the logical management interface can be assigned to one or both ports. The physical port description follows:

•Two Gigabit Ethernet 1000BASE-SX fiber-optic cables can plug into the LC connectors on the front of the Cisco 4100 Series Wireless LAN Controller, and they must be connected to the same subnet. Note that the two Gigabit Ethernet ports are redundant--the first port that becomes active is the master, and the second port becomes the backup port. If the first connection fails, the standby connection becomes the master, and the failed connection becomes the backup port.

Note The 1000BASE-SX circuits provide 100/1000 Mbps wired connections to the network through 850nM (SX) fiber-optic links using LC physical connectors.
