Before You Begin
Before beginning installation, determine bridge location. Because the unit is a radio device, unit and antenna location are important to ensure optimum radio range and throughput:
•To maximize the range of a building-to-building connection, install the antenna as high as possible.
•Maintain a clear line of sight between wireless bridge antennas. Obstructions may impede performance or limit bridge ability to transmit and receive data.
•Place directional antennas at both ends with maximum path clearance.
Note: Before you install the bridge system, we recommend that you test the bridge using the 2.2 dBi antenna included in the package. Then install the wireless bridge with the appropriate antenna for your application. A lightning arrestor and low-loss antenna cable are included in the optional antenna kits or can be ordered separately.
Installing the Antenna
1 If applicable, with the unit powered off, attach a lightning arrestor to the antenna connector.
Note: The lightning arrestor provides surge protection to the bridge in the event of a lightning strike and is highly recommended if the antenna will be located outdoors.
2 Connect one end of the low-loss antenna cable to the lightning arrestor connected to the bridge antenna connector.
Note: Because of FCC and DOC regulations, the antenna connector on the Aironet bridge is of reverse polarity to the standard TNC connectors.
3 Connect the other end of the antenna cable to the 2.2 dBi antenna or to an external high-gain antenna.
4 Mount the bridge antenna at an appropriate elevation to ensure maximum path clearance and line-of-sight to the other bridge or device.
Installing the Ethernet Connection
The Aironet wireless Ethernet bridge supports three connection types: 10Base2 (Thinnet), 10Base5 (Thicknet), or 10BaseT (twisted pair). Connect only one Ethernet cable to each bridge. With the power off, connect the appropriate cable from your network to the bridge.
Attaching 10Base2 Cabling
1 Attach the 10Base2 (Thinnet) cabling to a BNC T-connector.
2 Attach the T-connector to the 10Base2 connector on the bridge.
3 If the unit is at the end of the Ethernet cable, install a 50-ohm terminator on the open end of the T-connector.
Caution Removing a terminator to install extra cable or breaking an existing cable to install a T-connector will cause a disruption in Ethernet traffic. Consult your LAN administrator before you change any Ethernet cable connections.
Attaching 10Base5 Cabling
1 Attach the transceiver connector to the 10Base5 (Thicknet) port.
2 Slide the locking mechanism into place.
3 Attach the other end of the transceiver drop cabling to an external transceiver.
Attaching 10BaseT Cabling
1 Plug the RJ-45 connector into the 10BaseT (twisted pair) port.
2 Connect the other end of the twisted pair cabling to the 10BaseT Ethernet LAN connection.
The console port and power connections are on the side of the bridge. The console connection is required for setting up initial configuration information. After configuration is complete, you may remove this cable unless or until additional configuration is required via the serial port.
Installing the Console Port Cable
Note: Use a straight-through cable with 9-pin male to 9-pin female connectors.
1 Attach the console port cable to the console port on the bridge.
2 Attach the other end of the console cable to the serial port on a terminal or PC running a terminal emulation program.
3 Set the terminal to 9600 baud, 8 data bits, No parity, 1 stop bit, and Xon/Xoff flow control.
Connecting Power to the Bridge
1 Connect the small plug on the end of the power pack cord into the bridge power port.
2 Plug the power pack into an electrical outlet (120VAC/60 Hz or 90-264VAC/47-63 Hz, as appropriate).
3 Push the on/off button to power on the bridge.
When power is initially applied to the bridge, all three indicators on the top panel will flash in sequence to test the functionality of the indicators.
Assigning the SSID
Use the console port to set the Service Set Identifier (SSID) that allows the wireless bridge to communicate with other nodes.The SSID is a unique, case-sensitive identifier that is attached to selected packets sent out over the radio network. Nodes associating to the bridge must use the same SSID or their association requests will be ignored. Determine a unique SSID for the bridges and make sure that all bridges in the network use the same SSID.
1 On the terminal connected to the console port, select Configuration from the Main menu.
2 From the Configuration menu, select Radio.
3 From the Radio menu, select SSID.
4 Enter a value for the SSID option. The SSID can have up to 32 characters. All devices in the same radio network must use the same SSID. This value is case sensitive.
Assigning IP Information
To enable remote access to the bridge using Telnet, HTTP, or SNMP, you must assign an IP address to the bridge.
Note: You can also assign other detailed internet addressing options, such as gateway address, subnet mask, or SNMP configuration. Refer to the user guide on the product CD for more information.
1 On the terminal connected to the console port, select Configuration from the Main menu.
2 From the Configuration menu, select Ident.
3 Use the INADDR option to assign an IP address. Be sure to assign a unique IP address to each bridge.
4 Use the INMASK option to define the internet subnet mask, if appropriate.
5 Use the GATEWAY option to define the gateway address, if appropriate.
Setting Root Configuration
Before performing detailed configuration, you should determine whether the bridge will be a root bridge or a non-root bridge. Refer to the Aironet 340 Series Wireless Bridge User Guide on the product CD for configuration examples. The default setting for a bridge is as a root unit. Use the following steps to change this setting.
1 Access the Configuration Radio menu.
–If you are using a terminal emulator, select Configuration > Radio from the Main menu.
–If you are using a browser, click Radio under the Configuration heading.
2 At the Configuration Radio menu, select on or off for the Enable root mode setting.
–If you are using a terminal emulator, enter a 2 to select the Root setting. The prompt will ask if you are sure you want to change the setting. Enter y to toggle the setting from on to off, or from off to on.
–If you are using a browser, click Allow Config Changes and then click On to set the bridge as a root unit, or click Off to set the bridge as a non-root unit.
Once the bridge is configured as a root or non-root unit, you can quit the terminal emulator or browser, disconnect the console port cable, and install the bridge in its desired location before proceeding with remote configuration.
Refer to the Aironet 340 Series Wireless Bridge User Guide on the product CD for details on configuration.
Safety Information for the Cisco Aironet 340 Series Wireless Bridge
The FCC with its action in ET Docket 96-8 has adopted a safety standard for human exposure to radio frequency (RF) electromagnetic energy emitted by FCC certified equipment. Cisco Aironet 340 Series products meet the uncontrolled environmental limits found in OET-65 and ANSI C95.1, 1991. Proper operation of this radio according to the instructions found in this manual and the users guide on the Cisco Aironet 340 Series Wireless Bridge product CD will result in user exposure that is substantially below the FCC recommended limits.
•Do not touch or move antenna(s) while the unit is transmitting or receiving.
•Do not hold any component containing the radio such that the antenna is very close or touching any exposed parts of the body, especially the face or eyes, while transmitting.
•Do not operate a portable transmitter near unshielded blasting caps or in an explosive environment unless it is a type especially qualified for such use.
•Do not operate the radio or attempt to transmit date unless the antenna is connected; if not, the radio may be damaged.
•Always orient a di-pole antenna such that it is at least 6 inches (15 cm) away from your body.
•High-gain, wall-mount or mast-mount antennas are designed to be professionally installed and should be located at a minimum distance of 12 inches (30 cm) or more from your body. Please contact your professional installer, VAR, or antenna manufacturer for proper installation requirements.
•Warning for laptop users: In order to comply with the FCC RF exposure limits, it is recommended when using a laptop with a PC client adapter, that the adapter's integrated antenna should not be positioned closer than 2 inches (5 cm) from your body or nearby persons for extended periods of time while it is transmitting (or operating). If the antenna is positioned less than 2 inches (5 cm) from the user, it is recommended that the user limit exposure time.
