Cisco 4100 Series Wireless LAN Controller Model Numbers
Cisco 4100 Series Wireless LAN Controller model numbers are as follows:
• AIR-WLC4112-K9 — The Cisco 4100 Series Wireless LAN Controller uses two redundant Gigabit
Ethernet connections to bypass single network failures, and communicates with up to 12 Cisco 1000
series lightweight access points. The 1000BASE-SX Network Adapters provide 100/1000 Mbps
wired connections to a network through 850nM (SX) fiber-optic links using LC physical connectors.
• AIR-WLC4124-K9 — The Cisco 4100 Series Wireless LAN Controller uses two redundant Gigabit
Ethernet connections to bypass single network failures, and communicates with up to 24 Cisco 1000
series lightweight access points.
• AIR-WLC4136-K9 — The Cisco 4100 Series Wireless LAN Controller uses two redundant Gigabit
Ethernet connections to bypass single network failures, and communicates with up to 36 Cisco 1000
series lightweight access points.
Note Cisco 4100 Series Wireless LAN Controller models come from the factory with 19-inch EIA equipment
rack flush-mount ears.
The following upgrade module is also available:
• AIR-VPN-4100 — VPN/Enhanced Security Module: Supports VPN, L2TP, IPSec and other
processor-intensive security options. This is a field-installable option for all Cisco 4100 Series
Wireless LAN Controllers.

Cisco 4400 Series Wireless LAN Controller model numbers are as follows:
• AIR-WLC4402-12-K9 — The 4402 Cisco 4400 Series Wireless LAN Controller uses two redundant
Gigabit Ethernet connections to bypass single network failures, and communicates with up to 12
Cisco 1000 series lightweight access points.
• AIR-WLC4402-25-K9 — The 4402 Cisco Wireless LAN Controller uses two redundant Gigabit
Ethernet connections to bypass single network failures, and communicates with up to 25 Cisco 1000
series lightweight access points.
• AIR-WLC4402-50-K9 — The 4402 Cisco Wireless LAN Controller uses two redundant Gigabit
Ethernet connections to bypass single network failures, and communicates with up to 50 Cisco 1000
series lightweight access points.
• AIR-WLC4404-100-K9 — The 4404 Cisco Wireless LAN Controller uses four redundant Gigabit
Ethernet connections to bypass one or two single network failures, and communicates with up to 100
Cisco 1000 series lightweight access points.
Note Cisco 4400 Series Wireless LAN Controller models come from the factory with integral 19-inch EIA
equipment rack flush-mount ears.
