Cisco 4100 Series Wireless LAN Controllers can communicate with the network through one or two
physical ports, and the logical Management Interface can be assigned to the one or two physical ports.
The physical port description follows:
•Two GigE 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 GigE 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 that the 1000BASE-SX circuits provides 100/1000 Mbps wired connections to the network through
850nM (SX) fiber-optic links using LC physical connectors.
