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.
