Cisco 4400 Series Wireless LAN Controllers
Cisco 4400 Series Wireless LAN Controllers are part of the Cisco Wireless LAN Solution. Each Cisco
4400 Series Wireless LAN Controller controls up to 100 Cisco 1000 series lightweight access points,
making it ideal for large-sized enterprises and large-density applications.

The 4402 Cisco 4400 Series Wireless LAN Controller has one set of two redundant front-panel SX/LC/T
SFP modules (SFP transceiver, or Small Form-factor Plug-in), and the 4404 Cisco 4400 Series Wireless
LAN Controller has two sets of two redundant front-panel SX/LC/T SFP modules:

The Cisco 4400 Series Wireless LAN Controller can be equipped with one or two Cisco 4400 series
power supplies. When the Cisco Wireless LAN Controller is equipped with two Cisco 4400 series power
supplies, the power supplies are redundant and either power supply can continue to power the Cisco 4400
Series Wireless LAN Controller if the other power supply fails.

One Cisco 4400 series power supply is included standard with the Cisco Wireless LAN Controller, and
is installed in Slot 1 at the factory. For redundancy, a second Cisco 4400 series power supply can be
ordered from the factory and may be installed in Slot 2. The same power supply also fits in Slot 1 and
can be used to replace a failed power supply in the field.
