Bridge GUI Guide: Introduction
3
The term Bridge is used consistently throughout user guidance
to refer to both ES- and FC-series Fortress hardware devices.
Fortress Bridges provide network security by authenticating
access to the bridged network and bridging encrypted wireless
transmissions to the wired Local Area Network (and/or wired
communication within the LAN) and by authenticating and
encrypting Wireless Distribution System (WDS) links.
Fortress Bridges are variously equipped for network
connectivity. When one or more radio is present, the Bridge
can both provide and protect wireless connections. Fortress
devices without radios act as overlay security appliances for
wireless networks. All Fortress devices are equipped for wired
Ethernet with varying numbers of ports.
Table 1.1 shows the various hardware configurations and
capabilities of current Fortress hardware devices.
The ES210 is additionally equipped with a GPS (Global
Positioning System) receiver and associated antenna port.
1.3.1.1 ES-Series Model Numbers
Fortress ES-series model numbers provide information about
the product platform and the number and type of radio(s) it
contains. Figure 1 breaks down the model number for an
ES520-35 Secure Wireless Bridge.
