Federal Communication Commission Interference Statement
This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. This
equipment generates, uses and can radiate radio frequency energy and, if not installed
and used in accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, the
user is encouraged to try to correct the interference by one of the following measures:
• Reorient or relocate the receiving antenna
• Increase the separation between the equipment and receiver
• Connect the equipment into an outlet on a circuit different from that to which the receiver
is connected
• Consult the dealer or an experienced radio/TV technician for help
FCC Caution: Any changes or modifications not expressly approved by the party
responsible for compliance could void the user's authority to operate this equipment. This
device complies with Part 15 of the FCC Rules. Operation is subject to the following two
conditions: (1) This device may not cause harmful interference, and (2) this device must
accept any interference received, including interference that may cause undesired
operation.
IEEE 802.11b or 802.11g operation of this product in the U.S.A. is firmware-limited to
channels 1 through 11.
IMPORTANT NOTE:
FCC Radiation Exposure Statement
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled
environment. This equipment should be installed and operated with a minimum distance
of 70 centimeters (27.5 inches) between the radiator and your body. This transmitter must
not be co-located or operating in conjunction with any other antenna or transmitter.
vii
Wireless 5 GHz Band Statements:
As the Access Point can operate in the 5150-5250 MHz frequency band it is limited by the
FCC, Industry Canada and some other countries to indoor use only so as to reduce the
potential for harmful interference to co-channel Mobile Satellite systems.
High power radars are allocated as primary users (meaning they have priority) of the
5250-5350 MHz and 5650-5850 MHz bands. These radars could cause interference and /
or damage to the access point when used in Canada.
The term “IC:” before the radio certification number only signifies that Industry Canada
technical specifications were met.
Industry Canada - Class B
This digital apparatus does not exceed the Class B limits for radio noise emissions from
digital apparatus as set out in the interference-causing equipment standard entitled
“Digital Apparatus,” ICES-003 of Industry Canada.
Cet appareil numérique respecte les limites de bruits radioélectriques applicables aux
appareils numériques de Classe B prescrites dans la norme sur le matérial brouilleur:
“Appareils Numériques,” NMB-003 édictée par l’Industrie.
Industry Canada Statement
Operation is subject to the following two conditions:
1) This device may not cause interference and
2) This device must accept any interference, including interference that may cause
undesired operation of the device
This device has been designed to operate with an antenna having a maximum gain of
23 dB. Antenna having a higher gain is strictly prohibited per regulations of Industry
Canada. The required antenna Impedance is 50 ohms.
To reduce potential radio interference to other users, the antenna type and its gain should
be so chosen that the EIRP is not more than required for successful communication.
Because high power radars are allocated as primary users (meaning they have priority) in
5250-5350 MHz, these radars could cause interference and/or damage to license exempt
LAN devices.

Chapter 1: Introduction
The RoamAbout RBT-4102, RBT-4102-BG, and RBT-4102-EU are IEEE 802.11a/b/g
access points that provide transparent, wireless high-speed data communications
between the wired LAN and fixed or mobile devices equipped with an 802.11a,
802.11b, or 802.11g wireless adapter.
This solution offers fast, reliable wireless connectivity with considerable cost savings
over wired LANs (which include long-term maintenance overhead for cabling). Using
802.11a and 802.11g technology, these access points can easily replace a 10 Mbps
Ethernet connection or seamlessly integrate into a 10/100 Mbps Ethernet LAN.
The RBT-4102, RBT-4102-BG, and RBT-4102-EU support up to eight Virtual Access
Points per physical radio interface, that is eight on the 802.11a radio and eight on
the 802.11g radio. This allows traffic to be separated for different user groups using
an access point that services one area. For each VAP, different security settings,
VLAN assignments, and other parameters can be applied.
Each radio interface on the RBT-4102, RBT-4102-BG, and RBT-4102-EU can
operate in one of three modes:
• Access Point – Providing conectivity to wireless clients in the service area.
• Bridge (Point-to-Point) – Providing links to other access points in “Bridge” or
“Root Bridge” mode connecting wired LAN segments.
• Root Bridge (Point-to-Multipoint) – Providing links to other access points in
“Bridge” mode connecting wired LAN segments. Only one unit in the wireless
bridge network can be set to “Root Bridge” mode.
In addition, the access point offers full network management capabilities through an
easy to configure web interface, a command line interface for initial configuration
and troubleshooting, and support for Simple Network Management tools.
Radio Characteristics – The IEEE 802.11a/g standard uses a radio modulation
technique known as Orthogonal Frequency Division Multiplexing (OFDM), and a
shared collision domain (CSMA/CA). It operates at the 5 GHz Unlicensed National
Information Infrastructure (UNII) band for connections to 802.11a clients, and at
2.4 GHz for connections to 802.11g clients.
IEEE 802.11g includes backward compatibility with the IEEE 802.11b standard.
IEEE 802.11b also operates at 2.4 GHz, but uses Direct Sequence Spread
Spectrum (DSSS) and Complementary Code Keying (CCK) modulation technology
to achieve a communication rate of up to 11 Mbps.
The access point supports a 54 Mbps half-duplex connection to Ethernet networks
for each active channel (up to 108 Mbps in turbo mode on the 802.11a interface).

Introduction
Component Description
Antennas
The access point includes integrated diversity antennas for wireless
communications. A diversity antenna system uses two identical antennas to receive
and transmit signals, helping to avoid multipath fading effects. When receiving, the
access point checks both antennas and selects the one with the strongest signal.
When transmitting, it will continue to use the antenna previously selected for
receiving. The access point never transmits from both antennas at the same time.
The antennas transmit the outgoing signal as a toroidal sphere (doughnut shaped),
with the coverage extending most in a direction perpendicular to the antenna. The
antenna should be adjusted to an angle that provides the appropiate coverage for
the service area. For further information, see “Positioning the Antennas” on page
2-4.
External Antenna Connectors
The access point supports external antenna connections for both the 2.4 GHz and
5 GHz radios. These antennas offer a variety of options for extending the radio
range and shaping the coverge area. For a list of external antennas, their model
type and gain refer to “External Antennas” on page C-7.
For information on the external antennas available, refer to the following document
on the Enterasys Web site:
http://www.enterasys.com/support/manuals/n-s.html#R

Security Slot
The access point includes a Kensington security slot on the rear panel. You can
prevent unauthorized removal of the access point by wrapping the Kensington
security cable (not provided) around an unmovable object, inserting the lock into the
slot, and turning the key.
Console Port
This port is used to connect a console device to the access point through a serial
cable. This connection is described under “Console Port Pin Assignments” on page
B-3. The console device can be a PC or workstation running a VT-100 terminal
emulator, or a VT-100 terminal.
Ethernet Port
The access point has one 10BASE-T/100BASE-TX RJ-45 port that can be attached
directly to 10BASE-T/100BASE-TX LAN segments. These segments must conform
to the IEEE 802.3 or 802.3u specifications.
This port supports automatic MDI/MDI-X operation, so you can use straight-through
cables for all network connections to PCs, switches, or hubs.
The access point appears as an Ethernet node and performs a bridging function by
moving packets from the wired LAN to remote workstations on the wireless
infrastructure.
Note:
The RJ-45 port also supports Power over Ethernet (PoE) based on the IEEE
802.3af standard. Refer to the description for the “Power Connector” for
information on supplying power to the access point’s network port from a
network device, such as a switch, that provides Power over Ethernet (PoE).

Introduction
Reset Button
This button is used to reset the access point or restore the factory default
configuration. If you hold down the button for less than 5 seconds, the access point
will perform a hardware reset. If you hold down the button for 5 seconds or more,
any configuration changes you may have made are removed, and the factory default
configuration is restored to the access point.
Power Connector
The access point does not have a power switch. It is powered on when connected to
the AC power adapter, and the power adapter is connected to a power source. The
power adapter automatically adjusts to any voltage between 100~240 volts at 50 or
60 Hz. No voltage range settings are required.
The access point may also receive Power over Ethernet (PoE) from a switch or
other network device that supplies power over the network cable based on the IEEE
802.3af standard.
Note:
The access point supports both endspan and midspan PoE.
Note that if the access point is connected to a PoE source device and also
connected to a local power source through the AC power adapter, AC power will be
disabled.
1-6
Chapter 2: Hardware Installation
To install the access point, follow the steps outlined below:
1.
Select a Site – Choose a proper place for the access point. In general, the best
location is at the center of your wireless coverage area, within line of sight of all
wireless devices. Try to place the access point in a position that can best cover
its Basic Service Set (refer to “Infrastructure Wireless LAN” on page 3-2). For
optimum performance, consider these points:
• Mount the access point as high as possible above any obstructions in the
coverage area.
• Avoid mounting next to or near building support columns or other obstructions
that may cause reduced signal or null zones in parts of the coverage area.
• Mount away from any signal absorbing or reflecting structures (such as those
containing metal).
2.
Mount the Access Point – The access point can be mounted on any
horizontal surface or a wall.
Mounting on a horizontal surface – To keep the access point from sliding on the
surface, attach the four rubber feet provided in the accessory kit to the marked
circles on the bottom of the access point.
Mounting on a Wall – To mount on a wall or ceiling you must first attach the
mounting bracket to the base of the access point. Align the two mounting slots
on the bracket with the raised attaching slats and screw the unit into place
firmly.

Hardware Installation
Mounting Slots
Attaching Slats
Bottom of Access Point
The access point should be mounted only to a wall or wood surface that is at
least 1/2-inch plywood or its equivalent. To mount the access point on a wall,
always use its wall-mounting bracket. The access point must be mounted with
the RJ-45 cable connector oriented upwards to ensure proper operation.
• Using the mounting bracket, mark the position of the four screw holes on the
wall. For concrete or brick walls, you will need to drill holes and insert wall
plugs for the screws.
• Position the mounting bracket over the wall screw holes, then insert the
included screws and tighten them down to secure the bracket firmly to the
wall.
• Attach the access point to the mounting bracket. Line up the two mounting
points on the bracket with the two mounting slots on the bottom of the access
point (see the following figure). Place the mounting points of the bracket into
the mounting slots of the bracket, slide it into position so that the bracket
fastening screw on the access point lines up with the tab on the bracket. Then
screw down the fastening screw to secure the access point to the bracket.

Hardware Installation
4.
Connect the Power Cord – Connect the power adapter to the access point,
and the power cord to an AC power outlet.
Otherwise, the access point can derive its operating power directly from the
RJ-45 port when connected to a device that provides IEEE 802.3af compliant
Power over Ethernet (PoE).
Note:
If the access point is connected to both a PoE source device and an AC power
source, AC will be disabled.
Warning: Use ONLY the power adapter supplied with this access point. Otherwise, the
product may be damaged.
5.
Observe the Self Test – When you power on the access point, verify that the
Power indicator stops flashing and remains on, and that the other indicators
start functioning as described under “LED Indicators” on page 1-4.
If the PWR LED does not stop flashing, the self test has not completed
correctly. Refer to “Troubleshooting” on page A-1.
6.
Connect the Ethernet Cable – The access point can be wired to a 10/100
Mbps Ethernet through a network device such as a hub or a switch. Connect
your network to the RJ-45 port on the back panel with category 3, 4, or 5 UTP
Ethernet cable. When the access point and the connected device are powered
on, the Ethernet Link LED should light indicating a valid network connection.
Note:
The RJ-45 port on the access point supports automatic MDI/MDI-X operation, so
you can use straight-through cables for all network connections to PCs, switches,
or hubs.
7.
Position the Antennas – Each antenna emits a radiation pattern that is
toroidal (doughnut shaped), with the coverage extending most in the direction
perpendicular to the antenna. Therefore, the antennas should be oriented so
that the radio coverage pattern fills the intended horizontal space. Also, the
diversity antennas should both be positioned along the same axes, providing
the same coverage area. For example, if the access point is mounted on a
horizontal surface, both antennas should be positioned pointing vertically up to
provide optimum coverage.
8.
Connect the Console Port – Connect the console cable (included with
RBT-4102) to the RS-232 console port for accessing the command-line
interface. You can manage the access point using the console port, the web
interface, or SNMP management software such as NetSight or HP’s OpenView.

Chapter 3: Network Configuration
Wireless networks support a standalone configuration as well as an integrated
configuration with 10/100 Mbps Ethernet LANs. The RoamAbout RBT-4102,
RBT-4102-BG, and RBT-4102-EU also provide bridging services that can be
configured independently on either the 5 GHz or 2.4 GHz radio interfaces.
Access points can be deployed to support wireless clients and connect wired LANs
in the following configurations:
• Ad hoc for departmental, SOHO or enterprise LANs
• Infrastructure for wireless LANs
• Infrastructure wireless LAN for roaming wireless PCs
• Infrastructure wireless bridge to connect wired LANs
The 802.11b and 802.11g frequency band which operates at 2.4 GHz can easily
encounter interference from other 2.4 GHz devices, such as other 802.11b or g
wireless devices, cordless phones and microwave ovens. If you experience poor
wireless LAN performance, try the following measures:
• Limit any possible sources of radio interference within the service area
• Increase the distance between neighboring access points
• Decrease the signal strength of neighboring access points
• Increase the channel separation of neighboring access points (e.g. up to 3
channels of separation for 802.11b, or up to 4 channels for 802.11a, or up to 5
channels for 802.11g)

Network Configuration
Network Topologies
Ad Hoc Wireless LAN (no Access Point)
An ad hoc wireless LAN consists of a group of computers, each equipped with a
wireless adapter, connected via radio signals as an independent wireless LAN.
Computers in a specific ad hoc wireless LAN must therefore be configured to the
same radio channel. An ad hoc wireless LAN can be used for a branch office or
SOHO operation.

Infrastructure Wireless LAN
The access point also provides access to a wired LAN for wireless workstations. An
integrated wired/wireless LAN is called an Infrastructure configuration. A Basic
Service Set (BSS) consists of a group of wireless PC users, and an access point
that is directly connected to the wired LAN. Each wireless PC in this BSS can talk to
any computer in its wireless group via a radio link, or access other computers or
network resources in the wired LAN infrastructure via the access point.
The infrastructure configuration not only extends the accessibility of wireless PCs to
the wired LAN, but also increases the effective wireless transmission range for
wireless PCs by passing their signal through one or more access points.
A wireless infrastructure can be used for access to a central database, or for
connection between mobile workers, as shown in the following figure.

Infrastructure Wireless LAN for Roaming Wireless PCs
The Basic Service Set (BSS) defines the communications domain for each access
point and its associated wireless clients. The BSS ID is a 48-bit binary number
based on the access point’s wireless MAC address, and is set automatically and
transparently as clients associate with the access point. The BSS ID is used in
frames sent between the access point and its clients to identify traffic in the service
area.
The BSS ID is only set by the access point, never by its clients. The clients only
need to set the Service Set Identifier (SSID) that identifies the service set provided
by one or more access points. The SSID can be manually configured by the clients,
can be detected in an access point’s beacon, or can be obtained by querying for the
identity of the nearest access point. For clients that do not need to roam, set the
SSID for the wireless card to that used by the access point to which you want to
connect.
A wireless infrastructure can also support roaming for mobile workers. More than
one access point can be configured to create an Extended Service Set (ESS). By
placing the access points so that a continuous coverage area is created, wireless
users within this ESS can roam freely. All wireless network cards and adapters and
wireless access points within a specific ESS must be configured with the same
SSID.

Infrastructure Wireless Bridge
The IEEE 802.11 standard defines a Wireless Distribution System (WDS) for bridge
connections between BSS areas (access points). The access point uses WDS to
forward traffic on links between units.
The access point supports WDS bridge links on either the 5 GHz (802.11a) or
2.4 GHz (802.11b/g) bands and can be used with various external antennas to offer
flexible deployment options.
Up to six WDS bridge links can be specified for each unit in the wireless bridge
network. One unit only must be configured as the “root bridge” in the wireless
network. The root bridge should be the unit connected to the main core of the wired
LAN. Other bridges must configure one “parent” link to the root bridge or to a bridge
connected to the root bridge. The other five available WDS links can be specified as
“child” links to other bridges. This forms a tiered-star topology for the wireless bridge
network.
When using WDS on a radio band, only wireless bridge units can associate to each
other. Wireless clients can only associate with the access point using a radio band
set to access point.

Appendix B: Cables and Pinouts
Twisted-Pair Cable Assignments
For 10/100BASE-TX connections, a twisted-pair cable must have two pairs of wires.
Each wire pair is identified by two different colors. For example, one wire might be
green and the other, green with white stripes. Also, an RJ-45 connector must be
attached to both ends of the cable.
Note:
Each wire pair must be attached to the RJ-45 connectors in a specific
orientation. (See “Straight-Through Wiring” on page B-2 and “Crossover
Wiring” on page B-3 for an explanation.)
Note:
DO NOT plug a phone jack connector into the RJ-45 port. Use only twisted-pair
cables with RJ-45 connectors that conform with FCC standards.
The following figure illustrates how the pins on the RJ-45 connector are numbered.
Be sure to hold the connectors in the same orientation when attaching the wires to
the pins.
10/100BASE-TX Pin Assignments
Use unshielded twisted-pair (UTP) or shielded twisted-pair (STP) cable for RJ-45
connections: 100-ohm Category 3 or better cable for 10 Mbps connections, or
100-ohm Category 5 or better cable for 100 Mbps connections. Also be sure that the
length of any twisted-pair connection does not exceed 100 meters (328 feet).
The RJ-45 port on the access point supports automatic MDI/MDI-X operation, so
you can use straight-through or crossover cables for all network connections to PCs,
switches, or hubs. In straight-through cable, pins 1, 2, 3, and 6, at one end of the
cable, are connected straight through to pins 1, 2, 3, and 6 at the other end of the
cable.
