CAUTION: The 3Com power supply (part number 61-0107-000) input relies on a 16A rated

building fuse or circuit protector for short circuit protection of the line to neutral conductors.

Wall-mounting the Bridge

The Bridge comes equipped with a cradle for mounting on a wall. For additional security, the Bridge also

comes with a locking bar, which can be used with a security lock (not provided) to lock the Bridge to the

cradle after the Bridge is mounted to the wall.

To wall-mount the Bridge:

1Screw the cradle to a wall.

2Route the power and Ethernet cables through the large opening in the cradle.

The figures below show the cradle being mounted to a wall, and then a cable being routed

through the large opening in the cradle.

3Connect the power and Ethernet cables to the ports on the front of the Bridge.

4Snap the Bridge onto the cradle.

To install the locking bar, push the locking bar through the opening in the side of the cradle until the

hole on the locking bar is exposed. Insert a lock (not provided) through the hole on the locking bar,

and then close the lock to secure it in place. See the user guide for detailed instructions.

Placing the Bridge on a Flat Surface

To install the Bridge on a flat surface such as a table or desktop, remove the backing from the four

4 Checking the LED Indicators

When the Bridge is connected to power, LEDs indicate activity as follows (solid LED indicates connection;

blinking LED indicates activity):

5 Attaching An External Antenna

The Bridge has two internal diversity dual-band antennas. If you want to increase the range of the

Bridge, an external antenna can be attached to the external antenna connector on the Bridge. The

3Com-approved external antenna for this Bridge is the 3Com 2.4/5 GHz Omnidirectional Workgroup

Bridge Antenna (3CWE501). For more information, go to www.3Com.com

6 Determining if you Need to Configure the Bridge

If your network has a DHCP server and no special security requirements, you can most likely use the

Bridge just as it is shipped from the factory. View the Bridge’s default settings on the next page to

determine whether or not you need to configure the Bridge for your network.

It takes about one to two minutes for the Bridge to determine if there is a DHCP server on the network.

If your network does not have a DHCP server or is more complex, you will want to configure the Bridge

and organize devices so that you can manage the wireless LAN easily and keep it secure.

Networks with a DHCP Server

If your network has a DHCP server, an IP address is automatically assigned to the Bridge. Use the 3Com

Wireless Infrastructure Device Manager (Widman) included on the 3Com Installation CD to locate the

Bridge on the network and view its IP address.

After you determine the Bridge’s IP address, you can enter that IP address into a web browser on a computer

on the same subnet to view the Bridge’s system status or change its configuration.

Networks without a DHCP Server

If your network does not have a DHCP server, the Bridge uses a default IP address (169.254.2.2) that is

assigned at the factory. You can use that IP address to configure the Bridge, or you can assign a new

IP address to the Bridge.

To verify that the Bridge is using the default IP address assigned at the factory:

1Connect a computer directly to the Bridge using the supplied standard Category 5

UTP Ethernet cable.

2Enter the Bridge’s default IP address (169.254.2.2) into the computer’s web browser.

If the Configuration Management System starts, the Bridge is using the factory assigned

IP address. You can configure the Bridge with the following login information:

■Login name: admin

■Password: none (blank)

If the Configuration Management System does not start, the Bridge is on a different subnet

than the computer. Install and start the 3Com Wireless Infrastructure Device Manager to

discover the Bridge’s IP address.

1INTRODUCTION

3Com wireless technology has all of the benefits of a local area network

(LAN) without the constraints and expense of network wiring.

3Com 11a/b/g Wireless LAN products provide easy, affordable, flexible

ways to extend wireless networks to more users. This guide shows how

you can use the 3Com 11a/b/g Wireless Workgroup Bridge in your office

or classroom to connect groups of wired Ethernet client devices to your

wireless LAN.

Product Features The 3Com 11a/b/g Wireless Workgroup Bridge includes a robust suite of

standards-based security features, and supports wireless network

standards including 802.11a and 802.11g.

Security To protect sensitive data broadcast over the radio, 3Com supports

Wireless Equivalent Privacy (WEP) RC4 64-bit, 128-bit and 152-bit

shared-key encryption. 3Com strengthens this basic security mechanism

with additional security features, including:

■MAC address access control lists

■IEEE 802.1x per-port user authentication with RADIUS server

authentication support

■Temporal Key Integrity Protocol (TKIP)

■Advanced Encryption Standard (AES)

■WiFi Protected Access (WPA)

■Extensible Authentication Protocol (EAP) support: EAP-TTLS and PEAP

6CHAPTER 1: INTRODUCTION

Wireless Network

Standards

Understanding the characteristics of the 802.11a and 802.11g standards

can help you make the best choice for your wireless implementation plans.

802.11a

Ratified in 2002, 802.11a is IEEE’s more recent wireless standard. It

operates at the 5 GHz band and supports data rates at up to 54 Mbps. For

those organizations demanding even higher speeds, a “turbo mode” feature

can boost throughput rates up to 108 Mbps. And because there are fewer

devices in the 5 GHz band, there’s less potential for RF interference.

However, because it is at an entirely different radio spectrum, it is not

compatible with 802.11g.

The higher spectrum provides about 50 m (164 ft) of coverage—about

half what 802.11g offers.

Consider 802.11a when you need high throughput in a confined space

and you are:

■Running high-bandwidth applications like voice, video, or multimedia

over a wireless network that can benefit from a five-fold increase in

data throughput.

■Transferring large files like computer-aided design files, preprint

publishing documents or graphics files, such as MRI scans for medical

applications, that demand additional bandwidth.

■Supporting a dense user base confined to a small coverage area.

Because 802.11a has a greater number of non-overlapping channels,

you can pack more wireless devices in a tighter space.

802.11g

802.11g operates in the 2.4 GHz band at up to 54 Mbps. Ratified in

2003, it supports the widest coverage—up to 100 m (328 ft). However, is

subject to a greater risk of radio interference because it operates in the more

popular 2.4 GHz band.

802.11b operates at up to 11 Mbps and supports coverage up to 100 m

(328 ft).

Network Configuration and Planning 7

Consider 802.11g when you need wider coverage and vendor

compatibility and you are:

■Maintaining support for existing 802.11b users and the existing

wireless investment while providing for expansion into 802.11g.

■Implementing a complete wireless LAN solution, including bridges,

gateways, access points and clients; Wi-Fi certification guarantees

compatibility among vendors.

■Providing access to hot spots in public spaces such as coffee shops or

university cafeterias.

Network

Configuration and

Planning

The Bridge can operate in either infrastructure or ad-hoc mode, and can

support a stand-alone wireless network configuration or an integrated

configuration with 10/100 Mbps Ethernet LANs.

Operating in infrastructure mode and connected to an Ethernet hub, a

single Bridge can combine up to 16 client devices—such as computers

with network adapters and printers—into a multiclient workgroup. The

workgroup associates with the wired network through a wireless LAN

access point such as the 3Com 11a/b/g Wireless LAN Access Point.

Infrastructure configurations extend your wireless LAN to devices that

would otherwise have to be connected to the wired network.

Operating in ad-hoc mode, two or more Bridges can associate among

themselves and communicate with one another at close range without an

access point. You may wish to set up an ad-hoc network, for example, if

a group is working away from the office, or if a group in the office needs

to share files apart from the wired LAN.

8CHAPTER 1: INTRODUCTION

Connecting to an

Ethernet Device

The Bridge is designed to be connected to an Ethernet client device such

as a hub, computer, or printer.

CAUTION: To avoid the possibility of a transmission loop situation between

the Bridge and an access point, which could disrupt network operation, do

not connect a Bridge that is set in Wireless Client (Infrastructure) mode

directly to the LAN (for example, through a wall port or through a hub that is

connected directly to the LAN).

About the Client List The Bridge supports up to 16 specific Ethernet client devices. It uses a

client list of MAC addresses to keep track of specific devices that have

been connected.

After 16 different devices have been connected, the client list is full, and

you must clear it before the next new device can associate with the

network through the Bridge.

To clear the list, you must access the Bridge’s Configuration Management

System. Details are in “Clearing the Ethernet Client List” on page 45.

Connecting to a Hub You can supply network connections for up to 16 devices, such as

Attaching An

External Antenna

The Bridge has two internal diversity dual-band antennas.

If you want to increase the range of the Bridge, an external antenna can

be attached to the external antenna connector on the Bridge.

The 3Com-approved external antenna for this Bridge is the

3Com 2.4/5 GHz Omnidirectional Workgroup Bridge Antenna

(3CWE501). For more information, go to www.3Com.com

Determining if you

Need to Configure

the Bridge

If your network has a DHCP server and no special security requirements,

you can most likely use the Bridge just as it is shipped from the factory.

It takes approximately one to two minutes for the Bridge to determine if

there is a DHCP server on the network.

View the Bridge’s default settings on page 20 to determine whether or

not you need to configure the Bridge for your network. If the factory

defaults meet your requirements, you can connect the Bridge as

described in “Connecting the Bridge” on page 14.

If your network does not have a DHCP server or is more complex, you

may have to configure the Bridge and organize devices so that you can

manage the wireless LAN easily and keep it secure. You can use the

3Com Wireless Infrastructure Device Manager (Widman) included on the

3Com Installation CD.

For non-U.S. versions of the Bridge, you need to set the Country mode.

This is done when you first open the Bridge’s Configuration Management

System. See “Using the Configuration Management System” on page 27

for instructions.

Networks with a DHCP Server

If your network has a DHCP server, an IP address is automatically assigned

to the Bridge. Use the 3Com Wireless Infrastructure Device Manager

(Widman) included on the 3Com Installation CD to locate the Bridge on

the network and view its IP address.

Alternatively, you can enter the Bridge’s IP address into a web browser on

a computer on the same subnet to view the Bridge’s system status or

change its configuration. See “Configuring the Bridge” on page 23 for

instructions.

Determining if you Need to Configure the Bridge 19

Networks without a DHCP Server

If your network does not have a DHCP server, the Bridge uses a default

IP address (169.254.2.2) that is assigned at the factory. You can use that

IP address to configure the Bridge, or you can assign a new IP address to

the Bridge.

To verify that the Bridge is using the default IP address assigned at the

factory:

1Connect a computer directly to the Bridge using the supplied standard

Category 5 UTP Ethernet cable.

See Figure 12 on page 16 for a connection diagram.

2Enter the Bridge’s default IP address (169.254.2.2) into the computer’s

web browser.

■If the Configuration Management System starts, the Bridge is using

the factory assigned IP address. You can configure the Bridge with the

following login information:

■Login name: admin

■Password: none (blank)

See “Configuring the Bridge” on page 23 for detailed instructions.

■If the Configuration Management System does not start, the Bridge is

on a different subnet than the computer. Install and start the 3Com

Wireless Infrastructure Device Manager to discover the Bridge’s IP

address. See “Using the 3Com Wireless Infrastructure Device

Manager” on page 24 for instructions.

34 CHAPTER 3: CONFIGURING THE BRIDGE

Changing Wireless

Security Settings

Under System Configuration, click Wireless Security. The Wireless Security

Settings page appears, where you can select the type of security to be

used on the Bridge.

The Bridge can be configured to support three types of data encryption:

WEP, TKIP, and AES. After selecting a data encryption type, you can

select an authentication type.

The following sections describe the settings. To maintain wireless

association, the settings on clients and the access points they associate

with (or other members of an ad-hoc network) must match exactly.

No Security (Open System)

No encryption is used. The network communications could be intercepted

by unintended recipients.

40/64-bit Shared Key (WEP)

This option encrypts the wireless transmissions to protect data, but still

allows communication among compatible wireless LAN clients and access

points from third-party manufacturers that are Wi-Fi certified.

This type of security requires you to set up encryption in one of the

following ways:

■String—For use only with other 3Com 11a/b/g wireless devices, an

encryption string is a case-sensitive string of characters between 6 and

30 characters long. To enter the string, select Enter a string to

generate shared keys. Then type any combination of letters and

numbers in the space provided and select Apply.

■Shared keys—Hexadecimal keys are sequences of hexadecimal digits

arranged into four keys. A hexadecimal digit may be a letter from

A to F or a number from 0 to 9. This type of encryption is compatible

with equipment from other manufacturers that use Wi-Fi certified

40-bit encryption. To enter the keys, select Specify shared keys and

which to use. In the shared keys window, enter all the keys in the

provided spaces, then select a radio button in the Selected Key

column to specify which key to use and select Apply.

Using the Configuration Management System 35

104/128-bit Shared Key

This option can be used with other 3Com 11a/b/g Wireless LAN devices

and with equipment from certain manufacturers that also support 128-bit

shared key encryption. It provides a higher level of security than the 40-bit

Shared Key (Wi-Fi) option and uses a more complicated type of encryption.

This type of security requires you to set up encryption using a string or

shared keys as described in “40/64-bit Shared Key (WEP)” on page 34.

128/152-bit Shared Key

This option can be used with other 3Com 11a/b/g Wireless LAN devices

and with equipment from certain manufacturers that also support 152-bit

shared key encryption. It provides a higher level of security than the 128-bit

Shared Key option and uses a more complicated type of encryption. This

type of security requires you to set up encryption using a string or shared

keys as described in “40/64-bit Shared Key (WEP)” on page 34.

Click the button preceding Specify Shared Keys and Which Key to Use to

create or modify WEP keys.

TKIP

The Temporal Key Integrity Protocol (TKIP) option improves data

encryption over WEP scheme by dynamically updating the encryption

keys every 10,000 packets. TKIP provides per-packet key mixing, a

message integrity check, and a re-keying mechanism.

To use TKIP:

1On the Wireless Security page, select TKIP.

2Select WPA-PSK for home network or WPA for the scenarios where

RADIUS servers are employed:

■WPA-PSK: Enter a pass-phrase key or hexidecimal key. The key can be

generated based on a pass-phrase or a sequence of manually entered

64 hexidecimals. The 64 hexidecimals can be automatically generated

by selecting Generate a Random Key.

■WPA: Select an authentication scheme (TTLS or PEAP), a relevant

authentication type, a user name, and a password. If you select TLS,

enter an upload file name and password, and then select Upload.

3Select Apply.

Click the button of TKIP to set TKIP relevant parameters.

36 CHAPTER 3: CONFIGURING THE BRIDGE

AES

The Advanced Encryption Standard (AES) option uses the highest security

cipher for data encryption.

To use AES:

1On the Wireless Security page, select AES.

2Select WPA-PSK for home network or WPA for the scenarios where

RADIUS servers are employed:

■WPA-PSK: Enter a pass-phrase key or hexidecimal key. The key can be

38 CHAPTER 3: CONFIGURING THE BRIDGE

Using the Access

Control List

You can determine which clients can access the Bridge using the Access

Control List.

Follow these steps:

1Launch the Configuration Management System.

2Under System Configuration, click Access Control List.

3In the Access Control List page, click Add.

The Access Control List New ACL page appears.

4Enter the MAC address of the client you want to add to the

Access Control List, and select the permission type.

5Repeat steps 3 and 4 for each client.

6Select the Access Control List (ACL) Type:

■Allow—allows the client to access the Bridge.

■Deny—prohibits the client from accessing the Bridge.

CAUTION: Make sure that the MAC address of the computer through

which you are configuring the Bridge is included in the control list if you

want to set the access control type to Allow. If you want to set the access

control type to Deny, make sure that the MAC address of the computer is

not included in the access control list. Failure to do so results in access to

the Bridge being blocked; the Bridge will no longer be configurable

through the computer.

7Click Save.

To delete a client from the Access Control List, highlight the client and

then click Delete.

Using the Configuration Management System 39

Serial Port Under System Configuration, click Serial Port to set up network serial port

operation.

About UART

A Universal Asynchronous Receiver/Transmitter (UART) is the

fundamental hardware for serial communication, controlling the speed

and method of data transfer of the serial port.

Applications utilizing a network serial port between an RS-232 interface

and a wireless device use a TCP/IP socket connection. Any program that

uses standard TCP/IP network sockets may be used to communicate with

the serial port of the Bridge. Once a socket is established to the Bridge,

any data written to the socket is sent out the serial port of the Bridge. At

the same time, any data received by the serial port of the Bridge is

returned via the socket connection.

The Bridge network serial port may be used in two modes:

■Server Mode — TCP Listen Port

■Client Mode — TCP Connect Port

In Server Mode, the Bridge waits for a TCP/IP socket connection to be

made by the network program with which it will communicate.

Server Mode should be used if you have a central server that expects to

open a TCP/IP socket connection to the Bridge.

In Client Mode, the Bridge establishes a socket connection to the

IP address and port number specified in the configuration. Client Mode

should be used if your system expects the Bridge to open a TCP/IP socket

connection to a central server.

Configuring UART Settings

For proper operation, it is imperative that these settings always match the

settings of the device to which the bridge is connected via the RS-232

port. There are two groups of parameters that need to be configured to

accomplish this task: UART Settings and Flow Control Settings.

Flow control is the process of adjusting the flow of data from one device

to another to ensure that the receiving device can handle all of the

incoming data.

40 CHAPTER 3: CONFIGURING THE BRIDGE

To configure the UART settings:

1Select the baud rate of your device.

The baud rate indicates the data transfer rate of the serial port. The baud

rate ranges from 300 to 115200 bits per second (bps). Standard rates are

300, 1200, 2400, 9600, 19200, 38400, 57600, 115200.

2Determine the data bits setting of the device you are connecting to the

Bridge, then set the Data Bits setting for the bridge that matches the data

bits setting of that device.

The Data Bits setting determines the number of bits used to transmit

data. The possible values are 7 and 8.

3Determine the stop bits setting of the device you are connecting to the

Bridge, then set the Stop Bits setting on the Bridge that matches the stop bits

setting of that device.

The Stop Bits setting determines the number of bits used to represent an

end of a character. The value can be 1 or 2.

4Determine the parity bit setting of the device you are connecting to the

Bridge, then set the Parity Bit setting on the Bridge that matches the parity

bit setting of that device.

The Parity Bit setting is used to check for correct data transmission.

Options are: none, even, and odd.

5Set the flow control setting.

Flow control becomes an important factor when one of the devices is

capable of transmitting data at a rate faster than the other can receive it.

There are two basic types of flow control, hardware and software.

Configuring Operation Mode

■Select CLI Console if you want to configure the Bridge through

CLI commands.

Attach your computer to the serial port on the Bridge, and then

configure the Bridge through the computer.

■Select Network Serial Port to establish a TCP/IP socket with a remote

computer in either infrastructure or ad-hoc mode. This allows you to

do data communication with the remote computer, rather than

configure the Bridge.

Using the Configuration Management System 41

Configuring Network Serial Port Settings

For Server Mode, click Server Mode and enter the port number to which

the Bridge connects in the List on port field. The default port number is

4000.

For Client Mode, select Client Mode and enter the IP address and port

number to which the Bridge connects. The default port number is 4000.

Applying Settings

After you set the UART settings, operation mode, and network serial port

settings, select Apply to make the settings take effect.

The socket can be substantially established between a client and server;

that is, a Bridge in server mode and the other in client mode. The Bridge

with the Network Serial Port option set cannot work alone. Generally, a

Bridge is set to server mode first, which listens to a designated port. The

other Bridge is then set to client mode, which connects to the designated

port on the IP address of the Bridge set to server mode.

Resetting the Bridge If the Bridge stops responding correctly, you can perform a reset, which

disrupts the network association temporarily, but does not affect Bridge

configuration settings that have already been applied with Apply.

To reset the Bridge, under Tools, click Reset Wireless Workgroup Bridge.

In the next page, click Reset.

The Bridge can also be reset using the Wireless Infrastructure Device

Manager (Widman). Right-click the Bridge in Widman, and then select

Reset.

42 CHAPTER 3: CONFIGURING THE BRIDGE

Restoring the Bridge

to Factory Defaults

You can restore Bridge settings to the defaults that were set at the

factory either manually or through software.

To restore the settings manually, insert a pointed object (such as the end

of a straightened paper clip) into the reset hole on the back of the unit

near the RJ-45 connector and hold for five seconds.

To restore the settings through software:

1Under Tools, click Restore Factory Defaults.

2Click Restore.

If the Bridge was using an IP address setting other than the default,

restoring the factory defaults will change the IP address. If you want to

continue configuring the Bridge, do the following:

1Close your browser.

2Return to the 3Com Wireless Infrastructure Device Manager and click Refresh.

3Select the device and click Configure to start a new configuration session.

Upgrading the

System

You can download firmware updates or updates of the Configuration

Management System from the 3Com Web site and install those updates

on the Bridge.

Options for upgrading the system include using a Trivial File Transfer Protocol

(TFTP) server or File Transfer Protocol (FTP) server. The Bridge acts as a TFTP or

FTP client to receive the download. Alternatively, you an use the HTTP option

and upload the firmware from a downloaded file placed on your computer.

Clearing the Ethernet

Client List

The Bridge supports up to 16 specific clients (for example, computers and

printers) and keeps track of the clients with a list of their MAC addresses.

After the client limit is reached, you must clear the client list to allow a

new client to associate with the network. For example, in a hub

configuration with 16 clients connected, if you disconnect a desktop

computer and connect a new laptop in its place, you must clear the client

list to establish network association for the laptop.

To clear the Ethernet Client List:

1Disconnect a client by unplugging its Ethernet cable from the hub or the

Bridge.

2Launch the Configuration Management System.

3Under System Status, click Ethernet Client List.

4In the Ethernet Client List page, click Clear Client List.

The Bridge erases the client list. Clients that remain connected to the Bridge

are added to the list automatically when they next interact with the network.

For details on how to download a firmware update from the 3Com

customer support Web site and install it on your Bridge, see “Upgrading

the System” on page 42

You are running

Windows NT. After you

connect the Bridge, your

computer cannot obtain a

valid IP address.

The Bridge configuration settings may not be compatible

with the network. If they are not, and your Windows NT

computer is set up to obtain its IP address from a DHCP

server, the Bridge is unable to associate with the network

to obtain the IP address.

To work around this problem, set a static IP address on

your computer. Then set the Bridge configuration to

match the network. When the Bridge is able to

associate, reset your computer to obtain its IP address

from the DHCP server. If the Bridge should also obtain

its IP settings from the DHCP server, make sure this is

configured properly on the IP Network page and

applied just before ending the session.
