Summary of Key Features

Workgroup bridges are small, stand-alone units that provide wireless infrastructure connections for Ethernet-enabled devices. A device connected to a bridge communicates with a network infrastructure through Cisco Aironet access points.

The bridge connects to a hub through a standard Ethernet port using a 10BASE-T/RJ-45 (twisted pair) connector, and up to eight client devices can be connected to the hub. You can use an Internet browser or Telnet to configure the bridge.

The bridge communicates with Cisco Aironet access points, but does not communicate with wireless networking devices manufactured by other companies.

Note If you use the bridge to provide a wireless connection for only one device, you can connect the bridge directly to the device's Ethernet port using a crossover cable. See Appendix C for a pinout diagram of a crossover cable.

Back Panel and Indicator Lights

The bridge's back panel contains the configuration reset button, the Ethernet port, and the connection for the power adapter, as shown in Figure 1-1.

Figure 1-1 Back Panel of the Workgroup Bridge

The three indicator lights on top of the bridge report Ethernet activity, operational status, and radio activity. The indicators are labeled in Figure 1-2.

Figure 1-2 Indicator Lights on the Workgroup Bridge

•The Ethernet indicator signals Ethernet traffic on the wired LAN. This indicator blinks green when a packet is received or transmitted over the Ethernet infrastructure. The indicator blinks red when the Ethernet cable is not connected.

•The status indicator signals operational status. Blinking green indicates that the bridge is operating normally but is not communicating with an access point. Steady green indicates that the bridge is communicating with an access point.

•The radio indicator blinks green to indicate radio traffic activity. The light is normally off, but it will blink green whenever a packet is received or transmitted over the bridge's radio.

Network Configuration Using the Bridge

The bridge provides wireless LAN connections for up to eight clients and communicates with a Cisco Aironet access point as shown in Figure 1-3.
