Configuration Overview
The RoamAbout Wireless Ethernet Adapter transforms wired devices (for example.,
desktop computers an d pr inters ) into wirel ess devices. Th e RoamAbou t Wi reles s Ethernet
Adapter is easily integrated into your existing wireless network.
The RoamAbout Wireless Ethernet Adapter can be used in the following wireless
topologies:
•Wireless infrastructure networks, which require the RoamAbout Access Point.
•Wireless ad-hoc networks, which do not require the RoamAbout Access Point
Wireless Infrastructure Network
In a wireless infrastructure network, wireless clients communicate with an Access Point (AP)
connected to a wired LAN. A RoamAbout wireless infrastructure can support clients with
various supported oper at in g sys t ems. Infrastructure mode is of t en us ed i n sy st ems t hat h a ve
heavy network traffic and want to utilize the filtering capabilities of the AP.
The AP remains as a stationary part of the wireless L AN, unlike individual Ethernet Adapter
units that can be physically moved throughout the wireless LAN. The Ethernet Adapter
synchronizes communication with the AP. Individual Ethernet Adapter units do not
communicate directly with each other. All communication between multiple Ethernet
Adapter units, or between an Ethernet Adapter unit and a wired network client, go through
the AP.
Multiple Access Points can be used to extend the coverage area.
Figure 2-1 shows an example of an infrastructure network.

Client
The re-association capabilities of the IEEE 802.11 standard enable clients to move
throughout the wireless LAN area and roam between Access Points. Re-as so c iation can
occur as long as the Ethernet Adapter has the same network name as the AP to which it is
trying to make a connection.
2-2 Configuration Overview
Wireless Ad-Hoc Networks
Wireless ad-hoc networks, also known as peer-to-peer or independent networks, do not
include Access Points. Instead, the ad-hoc network is a loose association, or workgroup, of
computers that can communicate with each other using the PC Card in Ad-Hoc Mode.
Figure 2-2 shows a network in which three Ethernet Adapter units are used to provide
wireless connectivity between Ethernet devices.
In this configuration, the Ethernet Adapter units and PC cards mak e all four devices appear
to be connected by the same Ethernet cable. Using Ethernet Adapter units in this manner
provides a cost effective way to wirelessly link a small number of Ethernet devices.

Installation
This section describes how to install the RoamAbout W ireless Ethernet Adapter. It also
includes the installation of the PC (PCMCIA) wireless LAN card into the Ethernet Adapter.
NOTE
The Ethernet Adapter does NOT include a RoamAbout 802.11 DS PC card.
These cards are sold separately. Contact your Enterasys Representative for
more information.
Installation Procedure
To install the Ethernet Adapter, perform the following steps:
1) Remove your RoamAbout Ethernet Adapter from the packaging. The
Ethernet Adapter ships fully assembled. To install the PC Card and use the
Ethernet Adapter, some disassembly and re-assembly is required.
2) Remove the cap from the Ethernet Adapter by pressing on the side of the cap
to release it as shown in Figure 3-1. Removal of the cap reveals the PC card
slot.

4) Remove the small combs from the end cap.
The combs are generally not needed. The combs, when cu t to an approp riate

size, are for use only when the Ethernet Adapter is in an environment with
extreme vibrations. The combs prevent the PC card from vibrating out of the
socket.
5) Gently insert PC card (face up) into the designated slot as shown in
Figure 3-3.

6) Replace the cap on the Ethernet Adapter that you removed in step 3 by
snapping the cap straight down on the body.
7) If you are mounting the Ethernet Adapter, install the bottom mounting plate
where desired as shown in Figure 3-4. Then, place the Ethernet Adapter onto
the mounting plate and snap it into place. Ensure that the Ethernet Adapter is
secure.
Figure 3-4: Installing the Mounting Plate (Optional)
8) Connect a standard, straight-through 10BaseT Ethernet cable between the
RJ-45 port on the Ethernet Adapter and the network port on the computer
where you will install the Ethernet Adapter Manager configuration software.

9) Connect the six-pin DC power cable to the power supply.
10) Connect the AC power cord to the other side of the power supply.
11) Connect the round power plug to the Ethernet Adapter port labeled 5V DC.
12) Insert the AC power cord into the AC socket.
13) Verify the Ethernet Link LED is illuminated (Table 3-1), indicating a valid
Ethernet connection to your PC.
14) The RoamAbout Ethernet Adapter hardware is now ready for configuration
using the RoamAbout Ethernet Adapter Manager. Proceed to Chapter 4 to
install the Ethernet Adapter Manager.

Ethernet Adapter Manager Installation
This chapter describes how to install and configure the Ethernet Adapter Manager.
The RoamAbout Ethernet Adapter Manager is used to configu re the Ethernet Adapter. You
can install it on a PC or workstation runni ng Windows 95/98/ NT/2000 or Millen nium. The
Ethernet Adapter Manager allows you to graphically and remotely:
•Display a list of Ethernet Adapter stations running on th e local network
•Display and edit the current Ethernet Adapter configuration
•Save and load configurations
•Update the Ethernet Adapter firmware
NOTE
Installation
To install the Ethernet Adapter Manager, perform the following step s:
The Ethernet Adapter Manager communicates with the Ethernet Adapter
using a non-routing protocol. Your Ethernet Adapter units must be
accessible on the local Ethernet network to communicate with the Ethernet
Adapter Manager.
1) Insert the Ethernet Adapter Manager CD-ROM into the CD-ROM drive.
If the installation program does not begin automatically , preform the
following steps:
a) Click on the My Computer icon on your desktop.
b) Click o n the icon for the CD-ROM.
c) Double-click on the setup.exe icon.
The Welcome window appears.
2) Click NEXT to continue the installation, or CANCEL to terminate.
The Software License agreement appears.
