Controller Models - Cisco AIR-WLC4402-50-K9 Installation And Configuration Manual

Controller Models

The controller comes in 2 variants—4402 and 4404.
The 4404 controller has four front-panel slots for 1000BASE-SX, 1000BASE-LX, or 1000BASE-T SFP
modules, as described in the 1000BASE-SX, 1000BASE-LX, and 1000BASE-T SFP module Quick Start
Guide.
The 4402 Cisco Wireless LAN Controller is similar, except that it has two front-panel slots for
1000BASE-SX, 1000BASE-LX, or 1000BASE-T SFP modules instead of four. The 1000BASE-SX SFP
module provides 1000 Mbps wired connections through 850nM (SX) fiber-optic links using LC physical
connectors. The 1000BASE-LX SFP module provides 1000 Mbps wired connections through 1300nM
(LX/LH) fiber-optic links using LC physical connectors. The 1000BASE-T SFP module provides
1000 Mbps wired connections through CAT-5 or higher cables using RJ-45 physical connectors.

AIR-WLC4402-12-K9—This 4402-12 controller uses two redundant GigE connections to bypass
single network failures. That is, at any given time one of the Cisco 4400 Series Wireless LAN
Controller GigE connections is active and the other is passive. In case of a network failure, the active
connection becomes passive, and the passive connection becomes active. The 4402 controller has
one back-panel slot for future expansion modules and communicates with up to 12 access points
AIR-WLC4402-25-K9—This 4402-25 controller uses two redundant GigE connections to bypass
single network failures, and communicates with up to 25 access points. It has one back-panel slot
for future expansion modules.
AIR-WLC4402-50-K9—This 4402-50 controller uses two redundant GigE connections to bypass
single network failures, and communicates with up to 50 access points. It has one back-panel slot
for future expansion modules.
AIR-WLC4404-100-K9—This 4404-100 controller uses four redundant GigE connections to
bypass one or two single network failures, and communicates with up to 100 access points. It has
two back-panel slots for future expansion modules.
