Figure - Cisco 4400 Series Wireless LAN Controller
The Cisco 4400 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. The
VPN/Enhanced Security Module can also be installed in the field.
The 4400 series controller can be equipped with one or two Cisco 4400 series power supplies. When the
controller is equipped with two Cisco 4400 series power supplies, the power supplies are redundant, and
either power supply can continue to power the controller if the other power supply fails.
Catalyst 6500 Series Wireless Services Module
The Catalyst 6500 Series Wireless Services Module (WiSM) is an integrated Catalyst 6500 switch and
two Cisco 4404 controllers that supports up to 300 lightweight access points. The switch has eight
internal Gigabit Ethernet ports that connect the switch and the controller. The switch and the internal
controller run separate software versions, which must be upgraded separately.
Note Without any other service module installed, the Catalyst 6509 switch chassis can support up to seven
Cisco WiSMs, and the Catalyst 6506 with a Supervisor 720 can support up to four Cisco WiSMs. If one
or more service modules are installed, the chassis can support up to a maximum of four service modules
(WiSMs included). Redundant supervisors cannot be used with these maximum configurations.
