Cisco 4400 Series Controllers
Figure -
The Cisco 4400 Series Wireless LAN Controller is available in two models: 4402 and 4404.
The 4402 supports up to 50 lightweight access points while the 4404 supports up to 100, making it ideal
for large-sized enterprises and large-density applications.
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
The Catalyst 6500 Series Switch chassis can support up to five Cisco WiSMs without any other service
module installed. If one or more service modules are installed, the chassis can support up to a maximum
of four service modules (WiSMs included).
