CHAPTER 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.
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
Consider 802.11g when you need wider coverage and vendor
compatibility and you are:
Network
Configuration and
Planning
■
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 Ethernet
Adapters, 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.
The Ethernet Adapter 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 Ethernet Adapter 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 Enterasys Networks 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 Ethernet Adapters 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.

Connecting to an
Ethernet Device
The Ethernet Adapter 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 Ethernet Adapter and an access point, which could disrupt network
operation, do not connect a Ethernet Adapter 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).
VORSICHT: Um eine Übertragungsschleife zwischen dem
Ethernet-Adapter und einem Access Point zu verhindern, die den
Netzwerkbetrieb stören könnte, darf ein im Modus Wireless Client
(Infrastructure) (Drahtloser Client [Infrastruktur]) eingerichteter
Ethernet-Adapter nicht direkt mit dem LAN verbunden werden (z. B. über
eine Wandbuchse oder über einen direkt mit dem LAN verbundenen Hub).
About the Client List
The Ethernet Adapter 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 Ethernet Adapter.
To clear the list, you must access the Ethernet Adapter’s Configuration
Management System. Details are in “Clearing the Ethernet Client List” on
page 49.

CHAPTER 2: INSTALLING THE ETHERNET ADAPTER
Attaching An
External Antenna
The Ethernet Adapter has two internal diversity dual-band antennas.
If you want to increase the range of the Ethernet Adapter, an external
antenna can be attached to the external antenna connector on the
Ethernet Adapter.
The Enterasys Networks-approved external antenna for this Ethernet
Adapter is the Enterasys Networks 2.4/5 GHz Omnidirectional Workgroup
Ethernet Adapter Antenna. For more information, go to
http://www.enterasys.com/products/wireless
Determining if you
Need to Configure
the Ethernet
Adapter
If your network has a DHCP server and no special security requirements,
you can most likely use the Ethernet Adapter just as it is shipped from the
factory.
It takes approximately one to two minutes for the Ethernet Adapter to
determine if there is a DHCP server on the network.
View the Ethernet Adapter’s default settings on page 22 to determine
whether or not you need to configure the Ethernet Adapter for your
network. If the factory defaults meet your requirements, you can connect
the Ethernet Adapter as described in “Connecting the Ethernet Adapter”
on page 15.
If your network does not have a DHCP server or is more complex, you
may have to configure the Ethernet Adapter and organize devices so that
you can manage the wireless LAN easily and keep it secure. You can use
the Enterasys Networks Wireless Infrastructure Device Manager (Widman)
included on the Enterasys Networks Installation CD.
For non-U.S. versions of the Ethernet Adapter, you need to set the Country
mode. This is done when you first open the Ethernet Adapter’s Configuration
Management System. See “Using the Configuration Management System” on
page 29 for instructions.
Networks with a DHCP Server
If your network has a DHCP server, an IP address is automatically assigned
to the Ethernet Adapter. It takes approximately one to two minutes for the
Ethernet Adapter to determine if there is a DHCP server on the network.
Use the Enterasys Networks Wireless Infrastructure Device Manager
Determining if you Need to Configure the Ethernet Adapter
21
(Widman) included on the Enterasys Networks Installation CD to locate the
Ethernet Adapter on the network and view its IP address.
Alternatively, you can enter the Ethernet Adapter’s IP address into a web
browser on a computer on the same subnet to view the Ethernet
Adapter’s system status or change its configuration. See “Configuring
the Ethernet Adapter” on page 25 for instructions.
Networks without a DHCP Server
If your network does not have a DHCP server, the Ethernet Adapter uses a
default IP address (169.254.2.2) that is assigned at the factory. You can
use that IP address to configure the Ethernet Adapter, or you can assign a
new IP address to the Ethernet Adapter.
To verify that the Ethernet Adapter is using the default IP address
assigned at the factory:
1 Connect a computer directly to the Ethernet Adapter using the supplied
standard Category 5 UTP Ethernet cable.
See Figure 10 on page 18 for a connection diagram.
2 Enter the Ethernet Adapter’s default IP address (169.254.2.2) into the
computer’s web browser.
■
If the Configuration Management System starts, the Ethernet Adapter
is using the factory assigned IP address. You can configure the
Ethernet Adapter with the following login information:
■
Login name: admin
■
Password: none (blank)
See “Configuring the Ethernet Adapter” on page 25 for detailed
instructions.
■
If the Configuration Management System does not start, the Ethernet
Adapter is on a different subnet than the computer. Install and start
the Enterasys Networks Wireless Infrastructure Device Manager to
discover the Ethernet Adapter’s IP address. See “Using the Enterasys
Networks Wireless Infrastructure Device Manager” on page 26 for
instructions.

the network, select a device and view its properties, and launch the
Configuration Management System in your Web browser.
The Wireless Infrastructure Device Manager must be installed on a
computer that:
■
Has a working Ethernet adapter.
■
Is running Internet Explorer and one of the Windows operating
systems listed in “Using the Enterasys Networks Installation CD” on
page 23.
■
Is on the same subnet as the Ethernet Adapter.
See “Using the Enterasys Networks Installation CD” on page 23 for
installation instructions.
The device to be configured using the Wireless Infrastructure Device
Manager must be:
■
Connected to power.
■
Wired to the network, associating with the wireless network, or, in
some cases with the Ethernet Adapter, connected directly to the
computer.
If there is more than one device with the same name in the network (for
example, RoamAbout Ethernet Adapter - RBTSA), make a note of the
MAC address of the device you want to select so that you can identify it
in the device manager.
If you do not have a DHCP server on your network, it can take up to one
minute for a device to become discovered after it has been powered up.
To use the Enterasys Networks Wireless Infrastructure Device Manager:
1 Launch the device manager by selecting Start > Programs > Wireless
Infrastructure Device Manager.

The Dynamic Turbo mode allows automatic switching between normal and
turbo modes without modification by the user. The feature increases
throughput when bandwidth demands are high. When bandwidth demands
are low and at regular intervals, normal mode allows legacy connectivity and
new associations. The Dynamic Turbo mode connection between the
Ethernet Adapter and the access point may turn to normal mode connection
if another station associates with the access point in normal mode.
The Static Turbo mode operates by using two radio channels and does
not switch to normal mode. Static Turbo mode must be configured by the

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
Ethernet Adapter. Once a socket is established to the Ethernet Adapter, any data
written to the socket is sent out the serial port of the Ethernet Adapter. At the
same time, any data received by the serial port of the Ethernet Adapter is returned
via the socket connection. The serial port communicates to the wireless port only.
The serial port cannot communicate with the wired Ethernet port.
The Ethernet Adapter network serial port may be used in two modes:
■
Server Mode — TCP Listen Port
■
Client Mode — TCP Connect Port
In Server Mode, the Ethernet Adapter waits for a TCP/IP socket connection
to be made over the wireless port 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 Ethernet Adapter.
In Client Mode, the Ethernet Adapter establishes socket connection over
the wireless port to the IP address and port number specified in the
configuration. Client mode should be used if your system expects the
Ethernet Adapter to open a TCP/IP socket connection to a central server.
Configuring Operation Mode
Attach your computer to the serial port on the Ethernet Adapter, and
then configure the Ethernet Adapter through the computer.
■
Select Enable 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.
■
Select Disable to disable the Network Serial Port.
Using the Configuration Management System

Configuring UART Settings
For proper operation, it is imperative that these settings always match the
settings of the device to which the Ethernet Adapter 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.
To configure the UART settings:
1 Select the baud rate of your device.
The baud rate indicates the data transfer rate of the serial port.
2 Determine the data bits setting of the device you are connecting to the
Ethernet Adapter, then set the Data Bits setting for the Ethernet Adapter 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.
3 Determine the stop bits setting of the device you are connecting to the
Ethernet Adapter, then set the Stop Bits setting on the Ethernet Adapter 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.
4 Determine the parity bit setting of the device you are connecting to the
Ethernet Adapter, then set the Parity Bit setting on the Ethernet Adapter 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.
Configuring Network Serial Port Settings
For Server Mode, click Server Mode and enter the port number to which
the Ethernet Adapter 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 Ethernet Adapter connects. The default port
number is 4000.
44
CHAPTER 3: CONFIGURING THE ETHERNET ADAPTER
After configuring the port mode, you also need to configure the
following options:
■
Line Length – As data arrives on the serial port it is accumulated in a
buffer in the Ethernet Adapter. The Line length parameter sets the
maximum size for this buffer. When the number of characters in the
buffer reaches the Line length value the entire buffer is sent as the
data in a single network packet.
The value of Line length can range from 1 to 1,408 bytes. The default
value is 1,408.
Do not use values of line length less than 5 with a serial baud rate of
115,200 or greater.
■
Timeout – Often serial data arrives in small bursts of characters. When
the Ethernet Adapter receives a burst of data it will wait for a certain
period of time for additional data to be received. If additional data is
received, it is added to the receive buffer, and the Ethernet Adapter
begins to wait again. If additional data is not received for longer than
the period specified by the Timeout value, then the buffer of
characters received is sent in a single network packet, and the process
begins again.
The value of timeout is in units of milliseconds, and should be specified in
10 millisecond increments. The valid range for timeout is from 10 (0.01
second) to 65,000 (650 seconds). The default value is 10.
■
Delimiters – Some serial devices transmit and receive data in a known
structure. In these cases, there are often special characters that the
transmitting device uses to indicate a complete message has been
sent. These characters are referred to as delimiters. You can specify up
to five different delimiting characters to the Ethernet Adapter. When
the Ethernet Adapter adds one of these characters to its buffer of
serial received characters, it will immediately send that buffer as a
network packet.
The value of delimiters is specified as a list of hexadecimal values
separated by spaces. You may specify up to five different delimiter
values. For example, if you want to use the delimiter 41375, you must
type the following hex values:
0x34 0x31 0x33 0x39 0x35
If you are unsure of the hex value for your delimiter character, consult
the Web page www.asciitable.com for reference.

Disconnecting the Ethernet Adapter
53
Table 15 Troubleshooting (continued)
Symptom
Solution(s)
You are running Windows NT.
After you connect the
Ethernet Adapter, your
computer cannot obtain a
valid IP address.
The Ethernet Adapter 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 Ethernet Adapter is unable to
associate with the network to obtain the IP address.
To work around this, set a static IP address on your
computer. Then set the Ethernet Adapter
configuration to match the network. When the
Ethernet Adapter is able to associate, reset your
computer to obtain its IP address from the DHCP
server. If the Ethernet Adapter 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.
Access to the Ethernet
Adapter through Ethernet is
blocked because of incorrect
settings in the Access Control
List.
Disconnecting the
Ethernet Adapter
Restore the Ethernet Adapter to factory default settings
(see “Restoring the Ethernet Adapter to Factory Defaults”
on page 45). The factory default setting for the Access
Control List is disabled. After the factory default settings
are restored, the Ethernet Adapter can be accessed
through Ethernet again.
To disconnect the Ethernet Adapter:
CAUTION: Disconnecting the Ethernet Adapter ends the network
association. To avoid possible data loss, exit all networking applications on
connected devices before you disconnect the Ethernet Adapter.
VORSICHT: Wird die Verbindung des Ethernet-Adapters getrennt, wird

■
To remain in conformance with European spectrum usage laws for Wireless LAN operation, the above
2.4GHz and 5GHz channel limitations apply. The user should check the current channel of operation. If
operation is occurring outside of the allowable frequencies as listed above, the user must cease operating
the 11a/b/g Wireless Ethernet Adapter at that location and consult the local technical support staff
responsible for the wireless network.
■
The 5GHz Turbo mode feature is not allowed for operation in any European Community country.
■
This device must not be operated in ad-hoc mode using channels in the 5GHz bands in the European
Community. Ad-hoc mode provides a direct communication between two client devices without a
Wireless LAN Access Point.
■
This device must be used with Access Points that have employed and activated a radar detection feature
required for European Community operation in the 5GHz bands. This device will operate under the control
of the Access Point in order to avoid operating on a channel occupied by any radar system in the area. The
presence of nearby radar operation may result in temporary interruption in communications of this device.
The Access Point’s radar detection feature will automatically restart operation on a channel free of radar.
You may consult with the local technical support staff responsible for the wireless network to ensure the
Access Point device(s) are properly configured for European Community operation.
