Technical Assistance Center
The Cisco TAC is available to all customers who need technical assistance with a Cisco product, technology, or solution. Two types of support are available: the Cisco TAC website and the Cisco TAC Escalation Center. The type of support that you choose depends on the priority of the problem and the conditions stated in service contracts, when applicable.
We categorize Cisco TAC inquiries according to urgency:
•Priority level 4 (P4)—You need information or assistance concerning Cisco product capabilities, product installation, or basic product configuration. There is little or no impact to your business operations.
•Priority level 3 (P3)—Operational performance of the network is impaired, but most business operations remain functional. You and Cisco are willing to commit resources during normal business hours to restore service to satisfactory levels.
•Priority level 2 (P2)—Operation of an existing network is severely degraded, or significant aspects of your business operations are negatively impacted by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.
•Priority level 1 (P1)—An existing network is “down,” or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.

Overview
The Cisco Aironet 1400 Series Bridge (hereafter called the bridge) is a wireless device designed for building to building wireless connectivity. Operating in the 5.8 GHz UNII 3 band (5725 to 5825 MHz), derived from the 802.11a standard, the bridge delivers 6-54 Mbps data rates without the need for a license. The bridge is a self contained unit designed for outdoor installations, providing differing antenna gains as well as coverage patterns and supports both point-to-point and multipoint configurations.
The bridge uses a browser-based management system, but you can also configure the bridge using Cisco IOS commands or Simple Network Management Protocol (SNMP).
This chapter provides information on the following topics:
•Key Features, page 1-2
•Network Configuration Examples, page 1-5
•Bridge Specifications, page 1-6

Power
The bridge receives inline power from the Cisco Aironet Power Injector LR (hereafter called the power injector). Dual-coax Ethernet cables are used to provide Ethernet data and power from the power injector to the bridge. The power injector is an external unit designed for operation in a sheltered environment, such as inside a building. The power injector also functions as an Ethernet repeater by connecting to a Category 5 LAN backbone and using the dual-coaxial cable interface to the bridge.

Chapter 1 Overview
Key Features
D R A F T - C I S C O C O N F I D E N T I A L
The power injector uses an external 48 VDC power module and after detecting the presence of the bridge, injects the DC voltage into the dual coax cables to power the bridge.
Note The power injector and the power module should not be placed in an outdoor unprotected environment.
External Antenna
The bridge is available with an N-type RF connector on the front of the unit (see Figure 1-1) for an external 5.8-GHz antenna. The supported external antennas connect to the bridge antenna connector using the antenna’s 4.9 ft (1.5 m) long coax cable.
–9 dBi omnidirectional external antenna with vertical polarization
–9.5 dBi sector external antenna
–28 dBi dish external antenna
Note To meet regulatory restrictions, the external antenna bridge configuration and the external antenna must be professional installed.
Integrated Antenna
The bridge is available with an integrated 22.5 dBi patch array antenna. The antenna is covered with a special radome cover to protect the antenna from environmental elements. When configured with the integrated antenna, the antenna polarization is controlled by the mounting orientation of the bridge. The bridge must be physically rotated 90 degrees to obtain either horizontal or vertical polarization. A special polarization mark is designed into the bridge housing to indicate the polarization direction.
Dual-Coax Ethernet Ports
The bridge’s dual Ethernet ports accepts a pair of 75 ohm F-type connectors, linking the bridge to your 100BASE-T Ethernet LAN through the power injector. The dual coax cables are used to send and receive Ethernet data, plus the cables supply inline 48 VDC power from the power injector. For the location of the ports, refer to Figure 1-2.
Tip You can connect the dual coax cable connectors to either of the bridge’s Ethernet ports. The bridge senses the Ethernet signals and automatically switches internal circuitry to match the cable connections.
Metal Enclosure
The bridge uses a metal enclosure that supports outdoor operating environments and supports an industrial temperature operating range (refer to Bridge Specifications, page 1-6).

•The install indicator indicates installation mode is activated. During installation mode, the other indicators provide signal strength readings used for antenna alignment.
•The radio indicator blinks green to indicate radio traffic activity. The light is normally off, but it blinks green whenever a packet is received or transmitted over the bridge radio link. This indicator also provides signal strength readings during installation mode.
•The status indicator signals bridge association status. Blinking green indicates that the bridge is not associated with another bridge. Steady green indicates that the bridge is associated with at least one other bridge. This indicator also provides signal strength readings during installation mode.

D R A F T - C I S C O C O N F I D E N T I A L
•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.

D R A F T - C I S C O C O N F I D E N T I A L
Warnings
Translated versions of the following safety warnings are provided in Appendix A, “Translated Safety Warnings.”
Warning This warning symbol means danger. You are in a situation that could cause bodily injury. Before you work on any equipment, be aware of the hazards involved with electrical circuitry and be familiar with standard practices for preventing accidents. (To see translations of the warnings that appear in this publication, refer to the appendix “Translated Safety Warnings.”)
Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment.
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. For proper installation and grounding of the antenna, please refer to national and local codes (e.g. U.S.:NFPA 70, National Electrical Code, Article 810, in Canada: Canadian Electrical Code, Section 54).
Warning This product relies on the building’s installation for short-circuit (overcurrent) protection. Ensure that the protective device is rated not greater than:
120Vac, 15A U.S. (240Vac, 10A International)
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 Read the installation instructions before you connect the system to its power source.
Warning Do not work on the system or connect or disconnect cables during periods of lightning activity.
Warning Do not operate your wireless network device near unshielded blasting caps or in an explosive environment unless the device has been modified to be especially qualified for such use.
Warning Industry standards relating to radio frequency (RF) exposure limits for this product require that the antennas should be positioned no less than 6.6 ft (2 m) from your body or nearby persons.

Chapter 2 Installation Overview
Safety Information
D R A F T - C I S C O C O N F I D E N T I A L
Warning This unit is intended for installation in restricted access areas. A restricted access area can be accessed only through the use of a special tool, lock and key, or other means of security.
Safety Information
Follow the guidelines in this section to ensure proper operation and safe use of the bridge.
FCC Safety Compliance Statement
The FCC, with its action in ET Docket 96-8, has adopted a safety standard for human exposure to RF electromagnetic energy emitted by FCC-certified equipment. When used with approved Cisco Aironet antennas, Cisco Aironet products meet the uncontrolled environmental limits found in OET-65 and ANSI C95.1, 1991. Proper operation of this radio device according to the instructions in this publication results in user exposure substantially below the FCC recommended limits.
Safety Precautions
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. For proper installation and grounding of the antenna, please refer to national and local codes (e.g. U.S.:NFPA 70, National Electrical Code, Article 810, in Canada: Canadian Electrical Code, Section 54).
Each year hundreds of people are killed or injured when attempting to install an antenna. In many of these cases, the victim was aware of the danger of electrocution, but did not take adequate steps to avoid the hazard.
For your safety, and to help you achieve a good installation, please read and follow these safety precautions. They may save your life!
1.If you are installing an antenna for the first time, for your own safety as well as others, seek professional assistance.
2.Select your installation site with safety, as well as performance in mind. Remember: electric power lines and phone lines look alike. For your safety, assume that any overhead line can kill you.
3.Call your electric power company. Tell them your plans and ask them to come look at your proposed installation. This is a small inconvenience considering your life is at stake.
4.Plan your installation carefully and completely before you begin. Successful raising of a mast or tower is largely a matter of coordination. Each person should be assigned to a specific task, and should know what to do and when to do it. One person should be in charge of the operation to issue instructions and watch for signs of trouble.
5.When installing your antenna, remember:
a.Do not use a metal ladder.
b.Do not work on a wet or windy day.
