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.

• Install the bridge in an area where large steel structures such as shelving units, bookcases,

and ﬁling cabinets will not obstruct radio signals to and from the bridge.

• Install the bridge away from microwave ovens.

Connecting the Power

Adapter

Follow these steps to connect the power

adapter to the bridge:

1Plug the power adapter into a suitable

power receptacle.

2Plug the power connector into the back

of the bridge.

Note The bridge does not have an on/off

switch, so power is applied to the unit when

you plug it in.

The bridge begins the power-on self-test

(POST) when you apply power. The

indicator lights show the unit’s progress

during startup. The indicators

simultaneously ﬂash red, then amber, and

then green. Startup takes approximately 30

seconds.

Determine Conﬁguration Method

Installing the IP Setup Utility

The IP Setup Utility (IPSU) allows you to

ﬁnd the bridge’s IP address when it has been

assigned by a DHCP server. You may also

use IPSU to set the bridge IP address and

SSID, depending on which conﬁguration

method you choose.

The IPSU cannot query the bridge’s IP

address when the computer running IPSU is

ona differentsubnet thanthe bridge.If your

bridge receives an IP address from a DHCP

server, you must install and run IPSU on a

computer on the same subnet as the bridge.

However, because IPSU uses IP multicast, it

can set the bridge IP address and SSID when

the computer running IPSU is on a different

subnet than the bridge.

Note IPSU may not function correctly if

thecomputer onwhichyou installIPSU uses

Windows 95 or Windows 95A, and the

MicrosoftOfﬁceSuite hasnotbeen installed

on the computer. Install IPSU on another

computer if one is available.

1Put the Cisco Aironet Workgroup

Bridge CD in the CD-ROM drive of the

computer you are using to conﬁgure the

bridge.

2Use Windows Explorer to view the

contents of the CD. Double-click the

IPSU folder, and then double-click the

ﬁle called setup.exe. Follow the steps

provided by the installation wizard.

Conﬁguration Summary

• Choose the conﬁguration method best

suited for your network conﬁguration

and do the initial conﬁguration.

• Conﬁgure the bridge.

• Unplug the power adapter and

disconnect the bridge from the PC or

hub.

• Place the bridge near the device or hub

it will serve. Connect the bridge to the

hub with an Ethernet cable.

Options for Initial

Conﬁguration

You can use one of three methods to

conﬁgure the bridge:

• Use a computer connected to your

wired LAN or wireless network to

communicate with the bridge through a

Cisco Aironet access point. The

computer you use for conﬁguration

must be on the same subnet as the

bridge.

• Use a computer on your wired LAN to

communicate with the bridge through a

hub on your wired LAN. The computer

you use for conﬁguration must be on

the same subnet as the bridge.

• Use a non-networked computer to

communicate directly with the bridge

through a crossover cable.

Remote Conﬁguration through an Access Point

Note The workgroup bridge communicates only with Cisco Aironet Access Points.

1Adjust the following settings on the access point to allow it to communicate with the

bridge:

—On the access point’s Express

Setup management page, set

the access point’s SSID to

tsunami, which matches the

bridge’s default SSID.

—On the access point’s AP

Radio Data Encryption

management page, set the

encryption mode to off.

To conﬁgure the bridge using a computer connected to your network with an access point

and DHCP server, continue with Steps 2 through 4.

If you do not have a DHCP server, set your PC to an address of 192.168.200.5. Then open

the browser or Telnet to 192.168.200.1. Skip to the “Conﬁgure the Bridge” section.

2Place the bridge in the vicinity of an access point and plug in the power adapter.

The bridge communicates with the access point when you apply power to the bridge. If

yournetwork usesa DHCPserver,and ifthe bridge’s Ethernetport isconnected toa device,

the bridge receives an IP address on your network. When the bridge’s IP address is changed

from the default setting, it can no longer be set using the IPSU.

3When the status LED on the bridge is green (to show association of the bridge to the access

point), go to the association table. Find the entry WGB3XX_xxxxxx (xxxxxx is the last

six digits of the access point’s MAC address).

4Record the IP address of that entry. Browse to the bridge’s management home page and

complete the conﬁguration by following the steps in the “Conﬁgure the Bridge” section.

Conﬁguration through a Wired LAN

Note If the bridge is connected to the wired LAN and is communicating with an access point

on the same LAN, a network problem known as a bridge loop can occur. Avoid a bridge loop

by disconnecting the bridge from the wired LAN immediately after you conﬁgure it. For more

information on bridge loops, refer to the Cisco Aironet Workgroup Bridge Hardware

Installation Guide.

1Use a straight-through Ethernet

cable to connect the bridge to a

standard port on a hub on your

wired network.

2Plug in the bridge’s power

adapter. The bridge receives a

DHCP-assigned IP address.

3Double-click the IPSU icon on

your desktop to start the utility.

4When the utility window opens, make sure Get IP addr is selected in the Function box.

5Enter 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.Yourbridge’sMAC addressmight look likethe following example:11223a4D5566.

Note The MAC address ﬁeld is not case-sensitive.

6Click Get IP Address.

7When the bridge’s IP address appears in the IP Address ﬁeld, write it down.

If IPSU reports that the IP address is 192.168.200.1, the default IP address, then the bridge

did not receive a DHCP-assigned IP address. To assign an IP address, go to Step 8. The

computer you use to assign an IP address to the bridge must have an IP address of its own.

If you do not need to assign an address, skip to Step 13.

8Make sure Set Parameters is selected in the Function box of the IPSU window.

9Enter the bridge’s MAC address in the Device MAC ID ﬁeld.

ﬁeld is labeled Address.)

15 Press Enter. The bridge’s main menu page appears.

16 Disconnect the unit from your wired LAN and connect it to the hub it will serve.

Local Conﬁguration Using a Non-Networked Computer

If you use a non-networked computer to conﬁgure the bridge, you must use a crossover cable

to connect the computer to the bridge, and the computer must have a TCP/IP network protocol

and IPSU installed.

To use a non-networked computer to conﬁgure the bridge, follow these steps:

1Connect the bridge and a

non-networked PC with a

crossover cable.

2Power on both devices.

3Double-click the IP Setup icon on

your computer desktop.

4When the utility window opens,

make sure Set Parameters is

selected in the Function box.
