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 numrique respecte les limites de bruits radiolectriques applicables aux appareils numriques de Classe B prescrites dans la norme sur le matrial brouilleur:

Appareils Numriques, NMB-003 dicte par lIndustrie. 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.

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). 1-1 Introduction Package Checklist The RoamAbout package includes:

(802.11a Radio) 1-3 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:

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 points network port from a network device, such as a switch, that provides Power over Ethernet (PoE). 1-5 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. 2-1 Hardware Installation Attaching Slats Mounting Slots 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. 2-2 Hardware Installation Mounting Points Fastening Screw Align this tab with the Fastening Screw Mounting Slots Bracket 3. Lock the Access Point in Place To prevent unauthorized removal of the access point, you can use a Kensington Slim MicroSaver security cable (not included) to attach the access point to a fixed object. 2-3 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 HPs OpenView. 2-4 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) 3-1 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. Ad Hoc Wireless LAN Notebook with Wireless USB Adapter Notebook with Wireless PC Card PC with Wireless PCI Adapter 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. 3-2 Network Topologies Wired LAN Extension to Wireless Clients Server Desktop PC Switch Access Point Notebook PC Desktop PC 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 points 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 points 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. 3-3 Network Configuration Seamless Roaming Between Access Points Server Desktop PC Switch Switch Access Point Notebook PC Notebook PC Access Point

Desktop PC 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. 3-4 Network Topologies Network Core Wireless Bridge Links Between Access Points 802.11g Radio AP Link Root Bridge 802.11a Radio Bridge Link 802.11a Radio Bridge Link 802.11g Radio AP Link Bridge 802.11a Radio Bridge Link 802.11g Radio AP Link Bridge 802.11g Radio AP Link Bridge 3-5 Network Configuration 3-6 Appendix A: Troubleshooting Diagnosing Access Point Indicators Symptom Power LED is Off Troubleshooting Chart Action AC power adapter may be disconnected.

Check the switch configuration to be sure that PoE power is enabled for the switch and specified port. Also check that the switch has not exceeded its power budget and turned off the port power. The access point has detected a system error. Reboot the access point to try and clear the condition. If the condition does not clear, contact your local dealer for assistance. Verify that the access point and attached device are powered on. Be sure the cable is plugged into both the access point and Verify that the proper cable type is used and its length does not exceed corresponding device. specified limits. Check the cable connections for possible defects. Replace the defective cable if necessary. Note: For troubleshooting wireless connectivity problems, refer to the management guide. A-1 Troubleshooting A-2 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. 8 8 1 1 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.
