Figure - 4102 Airespace WLAN Appliance
The 4101 and 4102 Airespace WLAN Appliances are one-unit high 802.11 Wireless Appliances that
communicate indirectly through the switched network (Appliance Mode) with up to 36 associated
Airespace Access Points. The 4101 and 4102 Airespace WLAN Appliances can be factory-ordered with
an Enhanced Security Module (Crypto Card) to support VPN, IPSec and other processor-intensive tasks,
and with one (4101) or two (4102) 1000Base-SX network connectors to allow the Airespace WLAN
Appliance to communicate with the switched network at GigE (Gigabit Ethernet) speeds.
The two redundant GigE connections on the 4102 allow the Airespace WLAN Appliance to bypass single
network failures. At any given time one of the 4102 Airespace WLAN Appliance GigE connections is
active and the other is passive. Upon a switched network failure, the active connection becomes
passive, and the passive connection becomes active.
