  • Page 6 Introduction to the Wireless Bridge The Cisco Aironet 1400 Series Wireless Bridge is a high-performance outdoor-deployable wireless bridge that provides wireless connectivity between multiple network locations within a metro area with a low total cost of ownership. The bridge operates in the unlicensed UNII-3 frequency band (5725 to 5825 MHz) and provides high-speed data transfer rates of 6 to 54 Mbps.
  • Page 7 The following illustration shows the two configurations: Integrated antenna configuration 2 External antenna configuration The bridge system includes these major components: • Bridge • Bridge Power Injector LR • Power module • Grounding block • Multi-function mount...

  • Page 8: Network Configurations

    Network Configurations The following sections describe the bridge’s role in three common network configurations: point-to-point, point-to-multipoint, and port aggregation or redundancy. Point-to-Point Configuration In a point-to-point configuration, two bridges connect two LAN networks together using a wireless communication link. The following illustration shows a typical point-to-point configuration.

  • Page 9: Port Aggregation Or Redundancy Configuration

    Bridge Bridge Bridge Port Aggregation or Redundancy Configuration The port aggregation or redundancy configuration increases bandwidth or backup redundancy communications between two LANs. Port aggregation for increased bandwidth occurs when both wireless links simultaneously pass Ethernet traffic. Backup communication redundancy is achieved when the second wireless bridge link is used if the first link fails.

  • Page 11 Bridge Power Injector LR The bridge Power Injector LR delivers 48-VDC power to the bridge. It also serves as an Ethernet repeater between the internal LAN and bridge and provides surge protection for any charge that might build up on the Ethernet cable inner conductor.

  • Page 12: Power Module

    Two lengths of dual 75Ω coaxial cable are provided: 20 ft (6.1 m) and 50 ft (15.2 m). These cables connect the Power Injector LR to the bridge through the grounding block. Power Module The power module provides 48-VDC power at up to 60W to the Power Injector LR, which in turn provides power to the entire bridge system.

  • Page 13: Multi-Function Mount

    Grounding Block The grounding block provides lightning provides surge protection for any charge that might build up on the Ethernet cable inner conductor. It is normally installed inline with the 75Ω dual coaxial cables at the building entrance. The following illustration shows a typical grounding block. F-type coaxial connectors Ground wire lug Multi-Function Mount...

    Antenna Options The following optional antennas are available for the external antenna model of the bridge: • 9-dBi omnidirectional antenna • 9.5-dBi sector antenna • 28-dBi dish antenna...
  • Page 15 The following illustration shows these antennas. 9-dBi omnidirectional antenna 28-dBi dish antenna 9.5-dBi sector antenna Note To meet regulatory restrictions, these antennas must be professionally installed.
  • Page 16 9-dBi Omnidirectional Antenna The 9-dBi omnidirectional antenna covers 360 degrees, so it can receive signals from any direction. See the Cisco Aironet 1400 Series Wireless Bridge 9-dBi Omnidirectional Antenna document that ships with the antenna (and is also on Cisco.com) for additional information.

  • Page 17: Unpacking The Bridge

    28-dBi Dish Antenna The 28-dBi dish antenna provides a highly directional pattern that results in extended ranges between devices. See the Cisco Aironet 1400 Series Wireless Bridge 28-dBi Dish Antenna document that ships with the antenna (and is available on Cisco.com) for additional information.

  • Page 22 The process is described in detail in the Cisco Aironet 1400 Series Wireless Bridge Mounting Instructions that shipped with your bridge. When powered up the first time, the bridge searches for a DHCP server. If it finds one, the bridge uses the assigned address.

  • Page 23: Aligning The Antennas

    To verify the alignment and make finer adjustments, you can connect a voltmeter to the bridge’s RSSI voltage port. The port provides a DC voltage proportional to the received RF signal level. Panning and tilting the antenna through the signal path produces varying voltage readings. The maximum voltmeter reading (peak) indicates the optimum antenna position.
  • Page 24 4. Position the non-root bridge’s antenna to the azimuth, elevation, and polarization recommended by the site survey. If the site survey data is correct, the two antennas are pointed towards each other close to the line-of-site signal path. 5. Power up the non-root bridge. 6.

  • Page 29 Radio Service Set ID (SSID)—Enter the case-sensitive SSID. The SSID is a unique identifier that makes the bridge part of a specific wireless network. When the bridge is powered up for the first time, its default SSID is autoinstall. After a static IP address is assigned or the role in the radio network is changed from Install-Mode, the default SSID is tsunami.

  • Page 30: Safety Information

    The express setup puts the bridge on the network but will probably require additional configuring to conform with your network’s operational and security requirements. Consult the Cisco Aironet 1400 Series Wireless Bridge Software Configuration Guide or the Cisco Aironet Access Points and Bridges Running Cisco IOS Command Reference to obtain the information needed to complete the configuration.

  • Page 32 Warning Do not locate the antenna near overhead power lines or other electric light or power circuits, or where it can come into contact with such circuits. When installing the antenna, take extreme care not to come into contact with such circuits, as they may cause serious injury or death.
  • Page 33 Warning Never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available. Warning Do not work on the system or connect or disconnect cables during periods of lightning activity.
