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

Figure 1-1 Bridge Configurations
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
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).

Indicators
Four indicators are located on back of the housing to report installation/alignment conditions, bridge
status, radio activity, and Ethernet activity. The indicators are shown in Figure 1-2.
Figure 1-2 Bridge Connectors and Indicators
•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.

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.

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.

Safety Information
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.

Safety Information
c. Do dress properly—shoes with rubber soles and heels, rubber gloves, long sleeved shirt or
jacket.
6. If the assembly starts to drop, get away from it and let it fall. Remember, the antenna, mast, cable,
and metal guy wires are all excellent conductors of electrical current. Even the slightest touch of any
of these parts to a power line complete an electrical path through the antenna and the installer: you!
7. If any part of the antenna system should come in contact with a power line, don’t touch it or try to
remove it yourself. Call your local power company. They will remove it safely.
If an accident should occur with the power lines call for qualified emergency help immediately.

Chapter 2 Installation Overview
Installation Guidelines
Installation Guidelines
Because the bridge is a radio device, it is susceptible to common causes of interference that can reduce
throughput and range. Follow these basic guidelines to ensure the best possible performance:
•Install the bridge in an area where structures, trees, or hills do not obstruct radio signals to and from
the bridge.
•Install the bridge at a height sufficient to provide line-of-sight orientations.
Site Surveys
Because of differences in component configuration, placement, and physical environment, every
network application is a unique installation. Before installing multiple bridges, you should perform a site
survey to determine the optimum utilization of networking components and to maximize range,
coverage, and network performance.
Consider the following operating and environmental conditions when performing a site survey:
•Data rates—Sensitivity and range are inversely proportional to data bit rates. The maximum radio
range is achieved at the lowest workable data rate. A decrease in receiver sensitivity occurs as the
radio data increases.
•Antenna type and placement—Proper antenna configuration is a critical factor in maximizing radio
range. As a general rule, range increases in proportion to antenna height. However, do not place the
antenna higher than necessary, because the extra height also increases potential interference from
other unlicensed radio systems.
•Physical environment—Clear or open areas provide better radio range than closed or filled areas.
•Obstructions—Physical obstructions such as buildings, trees, or hills can hinder performance of
wireless devices. Avoid locating the devices in a location where there is an obstruction between the
sending and receiving antennas.
Unpacking the Bridge
Follow these steps to unpack the bridge:
Step 1 Open the shipping container and carefully remove the contents.
Step 2 Return all packing materials to the shipping container and save it.
Step 3 Ensure that all items listed in the “Package Contents” section are included in the shipment. Check each
item for damage. If any item is damaged or missing, notify your authorized Cisco sales representative.

Mounting the Bridge
Mounting the Bridge
Typically, the bridge is installed on a rooftop, mast, tower, wall, or a suitable flat surface. Each of these
installation methods requires different approaches to the installation process. This document provides a
mounting overview, refer to the Cisco Aironet 1400 Series Wireless Bridge Installation Instructions that
shipped with your bridge for detailed mounting instructions.
The bridge is available in two configurations
•Integrated antenna bridge (with 22.5 dBi directional antenna)
•External antenna bridge (with antenna connector for use with an external antenna)
Note To meet regulatory restrictions, the external antenna bridge configuration and the external antenna must
be professional installed.
Personnel installing the bridge must understand wireless bridging techniques, antenna alignment and
adjustment, and grounding methods. The integrated antenna configuration can be installed by an
experienced IT professional.
Mounting Hardware
The bridge is shipped with the following mounting hardware:
•Multi-function mount (consisting of two bridge brackets, and one mast bracket)
•Fastener hardware (consisting of nuts, bolts, washers, and U-bolts)
Multi-function Mount
The multi-function mount provides a method for mounting the bridge on a mast, tower, or an optional
roof mast mount. The multi-function mount permits easy azimuth and elevation adjustments for antenna
alignment purposes. The basic mounting procedure is shown below:
•Mount the two bridge brackets to the bridge with the support pins facing the sides of the bridge.
•Mount the mast bracket to the tower or mast using the supplied U-bolts.
•Suspend the bridge on the mast bracket using the bridge bracket support pins.
•Secure the bridge brackets to the mast bracket using the supplied nuts, bolts, and washers (hand
tighten).
•Align the bridge and tighten the nuts and bolts.
Bridge Brackets
The two bridge brackets mount on the back side of the bridge housing. Each bracket mounts on two
screw posts on opposite ends of the unit. The support pin on the bridge bracket must be facing the side
of the unit. These support pins are used to suspend the bridge in the notches on the mast mounting
bracket until you secure the mounting bolts.

Chapter 3 Mounting and Alignment Overview
Bridge LED Indicators
The bridge brackets must be positioned to obtain the correct antenna polarization that matches the
remote antenna. The bridge housing contains an antenna polarization mark consisting of an arrow on the
side of the housing. When the bridge is positioned so that the arrow is pointing up, the bridge antenna is
vertically polarized. For horizontal polarization, the arrow should be pointing from left to right. All
bridges must use the same antenna polarization for best operation.
Mast Bracket
The mast bracket attaches to a mast or tower support and is used to secure the bridge.The procedure for
attaching the mounting bracket to the support depends on the pipe diameter, as shown in Table 3-1.
Bridge LED Indicators
When you power up the bridge for the first time, it starts in a special installation mode. The LEDs
indicate the startup status, operating mode, association status, and received signal strength. This
information simplifies the process of activating the link and positioning the antenna from the bridge
mounting location.
The LEDs are mounted on the back of the housing, near the connectors (see Figure 1).

Chapter 3 Mounting and Alignment Overview
Aligning the Antenna Using LED Indications
You use the Install LED to determine when the bridge successfully associates with a remote bridge and
to verify its mode of operation. After association, the other three LEDs indicate signal strength (see
Table 3-3).
The startup and association sequence depends on the bridge configuration, which can be one of the
following types:
•Default—The bridge attempts to associate with a root bridge for 30 seconds. If it does not associate
with a root bridge, it then attempts to associate with a non-root bridge.
•Pre-configured—The bridge attempts to associate with a remote bridge in the configured mode,
either root or non-root. Because there are no time-outs, it is easier to align the antenna.
Aligning the Antenna Using LED Indications
You can align the integrated antenna using LEDs after the bridge successfully associates with a remote
bridge. In the installation mode before association to another bridge, the Install LED blinks amber. If the
bridge associates to a root bridge, the Install LED turns steady amber. If the bridge does not associate to
a root bridge in the first 30 seconds, the Install LED blinks green to indicate beacons are being
transmitted and the bridge is waiting for another non-root bridge to associate. After association, the
Install LED turns into steady green and the Ethernet, status, and radio LEDs then display signal strength
as shown in Table 3-3).
Note For the signal level (dBm), a smaller number represents a stronger signal because the signal level is given
as a negative value.
Note Each time you move the antenna, you must wait approximately 20 seconds before the LED patterns are
valid.

When using LEDs to maximize the signal, you adjust the antenna until as many LEDs as possible are
turned-on and the rest are blinking as fast as possible.
Aligning the Antenna Using the RSSI Voltage
The RSSI port outputs a DC voltage that is proportional to the received signal level. The RSSI voltage
is available whenever a signal is present, regardless of the bridge mode (installation or normal),
association status, or pre-configuration role setting. The RSSI voltage provides an instantaneous reading
as you move the antenna. The RSSI port is a female BNC connector on the bridge housing (see Figure 1).
The RSSI voltage increases linearly with signal level as shown in Table 4.
Note A larger RSSI voltage reading indicates a stronger signal.
The voltage varies from 0 to 2.7 volts for signals between -90 and -20 dBm, respectively. The accuracy
over temperature and component variations is ± 4dB. To obtain RSSI readings, you can use any
convenient voltmeter connected to the RSSI port using a cable with a male BNC connector.
1. Slow blinking rate of 1 Hz/sec.
2. Medium blinking rate of 2 Hz/sec.
3. Fast blinking rate of 4 Hz/sec.

Chapter 4 Configuring the Bridge for the First Time
Before You Start
Before You Start
Before you install the bridge, make sure you are using a computer connected to the same network as the
bridge, and obtain the following information:
•The following information from your network system administrator:
–
A system name
–
The case-sensitive wireless service set identifier (SSID) for your radio network
–
If not connected to a DHCP server, a unique IP address for your bridge (such as 172.17.255.115)
–
If the bridge is not on the same subnet as your PC, a default gateway address and subnet mask
–
A Simple Network Management Protocol (SNMP) community name and the SNMP file
attribute (if SNMP is in use)
•If you use IPSU to find or assign the bridge IP address, the MAC address from the label on the
bottom of the bridge (such as 00164625854c)
Resetting the Bridge to Default Settings
If you need to start over during the initial setup process, follow these steps to reset the bridge to factory
default settings using the power injector’s Mode button:
Step 1 Disconnect the power jack from the power injector.
Step 2 Press and hold the power injector’s MODE button while you reconnect the power jack.
Step 3 Hold the MODE button until the Status LED turns amber (approximately 1 to 3 seconds), and release the
button. All bridge settings return to factory defaults.
You can also use the web-browser interface to reset the bridge to defaults. Follow these steps to return
to default settings using the web-browser interface:
Step 1 Open your Internet browser. You must use Microsoft Internet Explorer (version 5.x or later) or Netscape
Navigator (version 4.x).
Step 2 Enter the bridge’s IP address in the browser address line and press Enter. An Enter Network Password
window appears.
Step 3 Enter your username in the User Name field. The default username is Cisco.

Chapter 4 Configuring the Bridge for the First Time
Obtaining and Assigning an IP Address
Obtaining and Assigning an IP Address
To browse to the bridge’s Express Setup page, you must either obtain or assign the bridge’s IP address
using one of the following methods:
•Use default address 10.0.0.1 when you connect to the bridge locally. For detailed instructions, see
the “Connecting to the Bridge Locally” section on page 4-3.
•Use a DHCP server (if available) to automatically assign an IP address. You can find out the
DHCP-assigned IP address using one of the following methods:
–
Provide your organization’s network administrator with your bridge’s Media Access Control
(MAC) address. Your network administrator will query the DHCP server using the MAC
address to identify the IP address. The bridge’s MAC address is on label attached to the bottom
of the bridge.
–
Use the Cisco IP Setup Utility (IPSU) to identify the assigned address. You can also use IPSU
to assign an IP address to the bridge if it did not receive an IP address from the DHCP server.
IPSU runs on most Microsoft Windows operating systems: Windows 9x, 2000, Me, NT, and XP.
You can download IPSU from the Software Center on Cisco.com. For additional information
refer to the “Obtaining and Installing IPSU” section on page 4-9.
Connecting to the Bridge Locally
If you need to configure the bridge locally (without connecting the bridge’s power injector to a wired
LAN), you can connect a PC to the power injector’s Ethernet port using a Category 5 Ethernet cable. You
can use a local connection to the Ethernet port much as you would use a serial port connection.
Note You do not need a special crossover cable to connect your PC to the bridge’s power injector; you
can use either a straight-through cable or a crossover cable.
-----Can someone verify the following DHCP Server statement-----
If the bridge is configured with default values and not connected to a DHCP server or cannot obtain an
IP address, it defaults to IP address 10.0.0.1 and becomes a mini-DHCP server. In that capacity, the
bridge provides up to twenty? IP addresses between 10.0.0.11 and 10.0.0.30 to an Ethernet-capable PC
connected to the power injector’s Ethernet port.
The mini-DHCP server feature is disabled automatically when you assign a static IP address to the
bridge.
Caution When a bridge with default settings is connected on a wired LAN and does not receive an IP address
from a DHCP server, the bridge provides an IP address to any DHCP requests it receives.
Follow these steps to connect to the bridge locally:
Step 1 Make sure that the PC you intend to use is configured to obtain an IP address automatically, or manually
assign it an IP address from 10.0.0.31 to 10.0.0.40. Connect your PC to the power injector using a
Category 5 Ethernet cable. You can use either a crossover cable or a straight-through cable.
Step 2 Power up the power injector.

to start over, follow the steps in the “Resetting the Bridge to Default Settings” section on page 4-2.
Step 4 After configuring the bridge, remove the Ethernet cable from your PC and connect the power injector to
your wired LAN.
Note When you connect your PC to the bridge’s power injector or reconnect your PC to the wired LAN, you
might need to release and renew the IP address on the PC. On most PCs, you can perform a release and
renew by rebooting your PC or by entering ipconfig /release and ipconfig /renew commands in a
command prompt window. Consult your PC operating instructions for detailed instructions.
Assigning Basic Settings
After you determine or assign the bridge’s IP address, you can browse to the bridge’s Express Setup page
and perform an initial configuration. Follow these steps:

Chapter 4 Configuring the Bridge for the First Time
Using the IP Setup Utility
Protecting Your Wireless LAN
To prevent unauthorized access to your network, you need to configure security settings. Because the
bridge is a radio device, the bridge communicates beyond the physical boundaries of your building.
Refer to the Cisco Aironet 1400 Series Software Configuration Guide to configure security features to
protect your network from intruders:
•Unique SSIDs that are not broadcast in the bridge beacon.
•WEP and additional WEP features, such as TKIP and broadcast key rotation
•Dynamic WEP and EAP authentication
Using the IP Setup Utility
IPSU enables you to find the bridge’s IP address when it has been assigned by a DHCP server. You can
also use IPSU to set the bridge’s IP address and SSID if they have not been changed from the default
settings.
Note IPSU can be used only on the following operating systems: Windows 95, 98, NT, 2000, ME, or XP.
The sections below explain how to install the utility, how to use it to find the bridge’s IP address, and
how to use it to set the IP address and the SSID.

Using the IP Setup Utility
Using IPSU to Find the Bridge’s IP Address
If your bridge receives an IP address from a DHCP server, you can use IPSU to find its IP address.
Because IPSU sends a reverse-ARP request based on the bridge MAC address, you must run IPSU from
a computer on the same subnet as the bridge. Follow these steps to find the bridge’s IP address:
Step 1 Double-click the IPSU icon on your computer desktop to start the utility. The IPSU screen appears (see
Figure 4-3).

Step 2 When the utility window opens, make sure the Get IP address radio button in the Function box is
selected.
Step 3 Enter the bridge’s MAC address in the Device MAC ID field. The bridge’s MAC address is printed on
the label on the bottom of the unit. It should contain six pairs of hexadecimal digits. Your bridge’s MAC
address might look like the following example:
000164xxxxxx
Note The MAC address field is not case-sensitive.
Step 4 Click Get IP Address.
Step 5 When the bridge’s IP address appears in the IP Address field, write it down.
If IPSU reports that the IP address is 10.0.0.1, the default IP address, then the bridge did not receive a
DHCP-assigned IP address. To change the bridge IP address from the default value using IPSU, refer to
the “Using IPSU to Set the Bridge’s IP Address and SSID” section on page 4-10.
Using IPSU to Set the Bridge’s IP Address and SSID
If you want to change the default IP address (10.0.0.1) of the bridge, you can use IPSU. You can also set
the bridge’s SSID at the same time.

Checking the LED Indicators
If your bridge is not associating with the remote bridge, check the four LED indicators on the back panel.
You can use them to quickly assess the unit’s status. Figure 5-1 shows the indicators.
Figure 5-1 Bridge LED Indicators
The indicators signals have the following meanings (for additional details refer to Table 5-3):
•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.
•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 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.
•The install indicator provides installation mode association status. During installation mode, the
other indicators provide signal strength readings used for antenna alignment.

Bridge Installation Mode LED Indications
When the bridge is initially powered-up, installation mode is activated and the bridge attempts to
associate to a root bridge for 60 seconds. If it is unable to associate with a root bridge, it automatically
assumes the root bridge role. The Install LED provides bridge association status during installation mode
as shown in Table 5-1.
You use the Install LED to determine when the bridge successfully associates with a remote bridge and
to verify its mode of operation. After association, the other three LEDs indicate signal strength (see
Table 5-2).
Note For the signal level (dBm), a smaller number represents a stronger signal because the signal level is given
as a negative value.

Power Injector LED Indicators
The bridge uses a blinking code to identify various error conditions. The code sequence uses a two-digit
diagnostic code that starts with a long pause to delimit the code, followed by the indicator flashing red
to count out the first digit, then a short pause, followed by the indicator flashing red to count out the
second digit (see Table 5-4).
Power Injector LED Indicators
The power injector contains three LED indicators to provide status information on the wired Ethernet
link, the bridge Ethernet link, and the bridge status. When the power injector is powered up, it sends a
constant discovery tone on the dual-coax cables to the bridge. When the bridge is connected to the
dual-coax cables, it returns the discovery tone to the power injector. When the power injector detects the
returned discovery tone, it applies +48 VDC to the dual-coax cables to the bridge.
When power is applied to the bridge, the bridge activates the bootloader and begins the POST operations.
The bridge begins to load the IOS image when the Post operations are successfully completed. Upon
successfully loading the IOS image, the bridge initializes and tests the radio.

Checking Basic Configuration Settings
Checking Basic Configuration Settings
Mismatched basic settings are the most common causes of lost wireless connectivity. If the bridge does
not associate with a remote bridge, check the following areas.
SSID
To associate, all bridges must use the same SSID. The bridge installation mode SSID is autoinstall and
the normal mode default SSID is tsunami. You should verify the SSID value shown on the Express Setup
page is the same for all bridges. You should also verify the bridges are configured for the proper network
role; only one bridge can be configured as the root bridge.
Security Settings
Remote bridges attempting to authenticate with your bridge must support the same security options
configured in the bridge, such as WEP, EAP or LEAP, MAC address authentication, Message Integrity
Check (MIC), WEP key hashing, and 802.1X protocol versions.
If a remote bridge is unable to authenticate with your bridge, verify the security settings are same as your
bridge settings. For additional information, refer to the Cisco Aironet 1400 Series Bridge Software
Configuration Guide.

Antenna Alignment
Antenna Alignment
If your bridges are unable to associate together, you should verify the basic configuration settings on all
bridges before attempting to verify bridge antenna alignment (refer to “Configuring the Bridge for the
First Time” section on page 4-1). If your basic configurations settings are correct, you can verify antenna
alignment by using the the RSSI port. The RSSI port can be used even when the bridges are not
associated.
Note To meet regulatory restrictions, the external antenna bridge configuration and the external antenna must
be professional installed.
The RSSI port outputs a DC voltage that is proportional to the received signal level. The RSSI voltage
is available whenever a signal is present, regardless of the bridge mode (installation or normal),
association status, or pre-configuration role setting. The RSSI voltage provides an instantaneous reading
as you move the antenna. The RSSI port is a female BNC connector on the bridge housing. To obtain
RSSI readings, you can use any convenient voltmeter connected to the RSSI port using a cable with a
male BNC connector.
The RSSI voltage increases linearly with signal level as shown in Table 6.
Note A larger RSSI voltage reading indicates a stronger signal.
The voltage varies from 0 to 2.7 volts for signals between -90 and -20 dBm, respectively.
For additional alignment information, refer to the Cisco Aironet 1400 Series Bridge Mounting
Instructions that shipped with your bridge.
Resetting to the Default Configuration
If you forget the password that allows you to configure the bridge, you may need to completely reset the
configuration. You can use the MODE button on the power injector or the web-browser interface.
