Cisco Aironet 1400 Series Wireless Bridge Hardware Installation Guide
OL-4072-01
Chapter 1 Overview
Network Configuration Examples
• The Ethernet indicator signals Ethernet traffic. This indicator blinks green when a packet is received
or transmitted over the Ethernet infrastructure. The indicator is off when the Ethernet link not
working or the port is shutdown. This indicator also provides signal strength readings during
installation mode.
For additional information on the LED indicators, refer to“Checking the LED Indicators” section on
page 5-2.
Receive Signal Strength Indicator Port
The bridge supports a radio signal strength indicator (RSSI) port for use in antenna alignment. The RSSI
port produces a DC voltage proportional to the strength of the received radio signal. The highest voltage
indicates the best antenna alignment position. The RSSI port is a male BNC connector located on the
bottom of the bridge housing (see Figure 1-2).
Note The RSSI port requires the use of a voltmeter and a cable with a female BNC connector.
Network Configuration Examples
This section describes the bridge’s role in three common wireless network configurations.
Point-to-Point Configuration
In a point-to-point configuration, two bridges are used to interconnect two remote LAN networks
together using a wireless communication link (see Figure 1-3). The bridge connected to the main LAN
network is classified as a root bridge and the other bridge is classified as a repeater bridge.
Figure 1-3 Point-to-Point Bridge Configuration
Port Aggregation or Redundancy Configuration
The port aggregation or redundancy configuration (Figure 1-4) is used to provide increased bandwidth
or backup redundancy communications between two LANs. Port aggregation or increased bandwidth
occurs when both wireless links are used to simultaneously pass Ethernet traffic. Backup communication
redundancy can be achieved with this configuration when one wireless bridge link is used only if the
other wireless bridge link fails.
