5 Configuring the Bridge for the First Time
This chapter describes how to configure basic settings on your bridge for the first time. The contents
of this chapter are similar to the instructions in the quick start guide that shipped with your bridge.
You can configure all the settings described in this chapter using the command-line interface (CLI), but
it might be simplest to browse to the bridge’s web-browser interface to complete the initial
configuration and then use the CLI to enter additional settings for a more detailed configuration.
This chapter contains these sections:
• Before You Start, page 7
• Obtaining and Assigning an IP Address, page 8
• Connecting to the Bridge Locally, page 9
• Assigning Basic Settings, page 10
• What To Do Next, page 14
• Assigning an IP Address Using the CLI, page 15
• Using a Telnet Session to Access the CLI, page 15
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:
• 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)
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.
br1430gsg.fm Page 7 Thursday, November 20, 2008 1:59 PM

THIRD FCC DRAFT (CISCO CONFIDENTIAL)
Step 2 Press and hold the power injector’s MODE button while you reconnect the power jack.
Step 3 Hold the MODEbutton until the Status LED turns amber (approximately 1 to 3 seconds) and
wait until the bridge boots up (Status LED turns green). 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.
Step 4 Enter the bridge password in the Password field and press Enter. The default password is
Cisco. The Summary Status page appears.
Step 5 Click System Software and the System Software screen appears.
Step 6 Click System Configuration and the System Configuration screen appears.
Step 7 Click Default.
Note If the bridge is configured with a static IP address, the IP address is not changed.
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 9.
• Use a DHCP server (if available) to automatically assign an IP address. You can find 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.

THIRD FCC DRAFT (CISCO CONFIDENTIAL)
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.
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.
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.
Step 2 Power up the power injector.
Step 3 Follow the steps in the “Assigning Basic Settings” section on page 10. If you make a mistake
and need to start over, follow the steps in the “Resetting the Bridge to Default Settings”
section on page 7.

Step 4 After configuring the bridge, remove the Ethernet cable from your PC and connect the power
injector to your wired LAN.
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:
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 screen appears.
Step 3 Press Tabto bypass the Username field and advance to the Password field.
Step 4 Enter the case-sensitive password Cisco and press Enter. The Summary Status page appears.

• IP Address—Use this setting to assign or change the bridge’s IP address. If DHCP is
enabled for your network, leave this field blank.
Note If the bridge’s IP address changes while you are configuring the bridge using the web-browser
interface or a Telnet session over the wired LAN, you lose your connection to the bridge. If
you lose your connection, reconnect to the bridge using its new IP address. Follow the steps
in the “Resetting the Bridge to Default Settings” section on page 7 if you need to start over.
• IP Subnet Mask—Enter the IP subnet mask provided by your network administrator so
the IP address can be recognized on the LAN. If DHCP is enabled, leave this field blank.
• Default Gateway—Enter the default gateway IP address provided by your network
administrator. If DHCP is enabled, leave this field blank.
• SNMP Community—If your network is using SNMP, enter the SNMP Community name
provided by your network administrator and select the attributes of the SNMP data (also
provided by your network administrator).
• Read-Only—indicates the bridge allows only SNMP read accesses. Using this option, an
SNMP user cannot change bridge configuration settings.
• Read-Write—indicates the bridge allows SNMP read and write accesses. This setting
allows an SNMP user to change the bridge configuration.
• Radio Service Set ID (SSID)—Enter the case-sensitive SSID (32 alphanumeric characters
maximum) provided by your network administrator. The SSID is a unique identifier that
remote bridges use to associate with your bridge.
• Broadcast SSID in Beacon—Use this setting to allow devices that do not specify an SSID
to associate with the bridge.
– Yes—This is the default setting; it allows a remote bridge that does not specify an
SSID to associate with the bridge.
– No—Remote bridges must specify an SSID to associate with the bridge. With No
selected, the SSID used by the remote bridge must match exactly the bridge’s SSID.
• Role in Radio Network—Click on the check box and button that describes the role of the
bridge on your network.
• Install Mode—Activates the bridge install and alignment mode. Specifies that the bridge
automatically determines the network role. If the bridge is able to associate to another
root bridge within 60 seconds, the bridge assumes a non-root bridge role. If the bridge is
unable to associate with another root bridge within 60 seconds, the bridge assumes a root
bridge role.
You can also pre-configure the bridge into root or non-root modes and avoid the 60
seconds automatic detection phase.

What To Do Next
After your bridge has basic settings, you need to complete your bridge’s configuration. You might need
to adjust the output power level and other network and security settings.
Output Power Level
Your bridge’s output power level might require adjustment under the following conditions:
• When bridges are installed less than 328 ft (100 m) apart, you should reduce their output power
to avoid overloading the bridge’s receivers.
To configure your bridge’s output power level, refer to the Power Levels and Channels for Cisco
Aironet Access Points and Bridges.
IP Address Assigned by DHCP (default setting); if DHCP is disabled, the
default setting is 10.0.0.1

Protecting Your Wireless LAN
To prevent unauthorized access to your network, you must 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 Wireless Bridge 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
Assigning an IP Address Using the CLI
When you connect the bridge to the wired LAN, the bridge links to the network using a bridge virtual
interface (BVI) that it creates automatically. Instead of tracking separate IP addresses for the bridge’s
Ethernet and radio ports, the network uses the BVI.
When you assign an IP address to the bridge using the CLI, you must assign the address to the BVI.
Beginning in privileged EXEC mode, follow these steps to assign an IP address to the bridge’s BVI:
Using a Telnet Session to Access the CLI
Follow these steps to access the CLI using a Telnet session. These steps are for a PC running Microsoft
Windows with a Telnet terminal application. Check your PC operating instructions for detailed
instructions for your operating system.
Command Purpose
Step 1 configure terminal Enter global configuration mode.
Step 2 interface bvi1 Enter interface configuration mode for the BVI.
Step 3 ip address address
mask
Assign an IP address and address mask to the BVI. This step
automatically saves the running configuration to the startup
configuration.
Note You lose your connection to the bridge when you
assign a new IP address to the BVI. If you need to
continue configuring the bridge, use the new IP
address to open another Telnet session to the
bridge.

Step 3 In the Host Name field, type the bridge’s IP address and click Connect.
6 Mounting the Bridge
This section describes in fundamental terms how to mount the bridge using its supplied mounting
hardware. Detailed mounting instructions are contained in the Cisco Aironet 1430 Wireless Bridge
Mounting Instructions, which shipped with your bridge. This document is also available on cisco.com.
Typically, the bridge is installed on a rooftop, mast, tower, wall, or a suitable flat surface. Each of these
installations requires a different approach. This document provides a mounting overview. For detailed
mounting instructions, refer to the Cisco Aironet 1400 Series Wireless Bridge Mounting Instructions
that shipped with your bridge.
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:
1. Mount the two bridge brackets to the bridge with the support pins facing the sides of the bridge.
br1430gsg.fm Page 16 Thursday, November 20, 2008 1:59 PM

17
THIRD FCC DRAFT (CISCO CONFIDENTIAL)
2. Mount the mast bracket to the tower or mast using the supplied U-bolts.
3. Suspend the bridge on the mast bracket using the bridge bracket support pins.
4. Secure the bridge brackets to the mast bracket using the supplied nuts, bolts, and washers (hand
tighten).
5. Connect the dual-coax cable to the power injector dual-coax ports (F-type connectors) on the
bridge.
Note You should securely tighten the cable connectors (15 to 20 inch-pounds) using a small wrench.
6. Connect the ground wire to the bridge.
7. 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.
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 2.
Ta b l e 2 Mast Bracket Attachment Methods

THIRD FCC DRAFT (CISCO CONFIDENTIAL)
Note The U-bolts supplied with the bridge support mast diameters up to 1.75 in. (44.5 mm). For
larger masts, you must supply the U-bolts to attach the bridge.
Bridge LEDs
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 5).

THIRD FCC DRAFT (CISCO CONFIDENTIAL)
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 3.
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 4).
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 60 seconds. If it does not
associate with a root bridge, it then attempts to associate with a non-root bridge.
• Preconfigured—The bridge attempts to associate with a remote bridge in the configured mode,
either root or non-root. Because there are no timeouts, 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 continuous amber. If the bridge does not
associate to a root bridge in the first 60 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 continuous green and the Ethernet, status, and radio LEDs then display
signal strength as shown in Table 4).

Note For the signal level (dBm), a smaller number represents a stronger signal because the signal
level is given as a negative value.
When using LEDs to maximize the signal, 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 produces 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. In Install mode, the RSSI voltage provides an
