Introduction Introduction Purpose of the Manual The purpose of this User’s Guide is to allow you to easily install and configure your Aironet Access Point. This will permit other wireless devices, such as fixed stations, mobile stations, or another Aironet Access Point (acting as a repeater), to be able to associate to it. These will then be able to communicate to each other over the radio network and to the rest of the network via the Ethernet or Token Ring link.
Introduction Safety Information The FCC with its action in ET Docket 96-8 has adopted a safety standard for human exposure to radiated frequency (RF) electromagnetic energy emitted by FCC certified equipment. The Aironet products meet the uncontrolled environmental limits found in OET-65 and ANSI C95.1, 1991. Proper operation of this radio according to the instructions found in this manual will result in the user exposure to be substantially below the FCC recommended limits.
Introduction Dipole Antenna Always orient antenna such that it is at least 15 cm (6 inches) away from your body. High Gain Antennas High gain wall mount or mast mount antennas are designed to be professionally installed and should be located at a minimum distance of 30 cm (12 inches) or more from your body. Please contact your professional installer, VAR, or antenna manufacturer for proper installation requirements.
Introduction Before You Start After unpacking the system, make sure the following items are present and in good condition. • Access Point (Ethernet or Token Ring model) • Power Pack. The power pack will be either 120VAC/ 60Hz or 90-264VAC/47-63Hz to 12-18VDC, whichever is appropriate for country of use. • Two standard 2 dBi dipole antennas If any item is damaged or missing, contact your Aironet supplier. Save all shipping and packing material in order to repack the unit should service be required.
Introduction Terminology When configuring your system, and when reading this manual, keep in mind the following terminology: Association – Each root unit or repeater in the infrastructure contains an association table that controls the routing of packets between the Access Point and the wireless infrastructure. The association table maintains entries for all the nodes situated below the Aironet Access Point on the infrastructure including repeaters and client nodes.
Introduction Repeater – A repeater is an Access Point that extends the radio range of the infrastructure. A repeater is not physically attached to the wired LAN, but communicates via radio to another Access Point, which is either a root unit or another repeater. Root Unit – The root unit is an Access Point that is located at the top, or starting point, of a wireless infrastructure.
Introduction Understanding the Infrastructure The infrastructure is designed like an upside-down tree with a root unit at the top and repeaters, stations, and mobile stations branching down from the root unit as shown below. The Aironet Access Point can serve as a root unit, providing wireless data communications between the Ethernet or Token Ring based networks and other stations/mobile stations or within the wireless infrastructure.
Introduction In the example, the Access Point maintains an area of RF coverage (cell). Any radio node within the cell’s area can communicate to any other node (via radio or across the wired LAN) using the Access Point. If a larger area of RF coverage is required, additional Access Points can be added either as root units, attached to the LAN, or as repeaters. Each Access Point adds its own cell, which can be used to provide additional coverage area, greater total bandwidth, or network redundancy.

Configuration Configuration This section describes the methods used to access and configure the Console system of the Aironet Access Point. This system contains all commands necessary to initially configure and monitor the operation of the unit. Accessing the Console System There are many ways in which you may configure and monitor the Aironet Access Point. When the unit is first powered up, basic configuration must initially be performed by accessing the Console Serial Port.
Configuration Configuring the Access Point To configure the Aironet Access Point so it will communicate with other nodes or repeaters, use the Console Port to set the SSID parameter. If you choose to set an IP address, remote access via telnet or an HTML browser will be possible. SSID Identifier (SSID) The SSID (Service Set Identifier) is a unique identifier that is attached to selected packets sent out over the radio network. This functions as a password to join the radio network.
Configuration Assigning an IP Address An IP address must be assigned to the unit before it can be accessed by telnet, HTTP, or SNMP. Other detailed internet addressing options (such as gateway address or SNMP routing) can also be defined. Refer to the Technical Reference Manual document number 710-004242 for further details. To assign an IP address: 1. 2. 3. 4. Select Configuration from the Main Menu. Select Ident from the Configuration Menu. Use the INADDR option to establish an IP address.

Appendix A Appendix A System Configurations Aironet Access Points are designed to provide maximum range and throughput enabling high-speed wireless access to different LAN segments within a building. You can use Aironet Access Points in many different network configurations.
Appendix A Point-to-Point LAN Connections The Point-to-Point Access Point Configuration uses two Access Points to bridge two different LANs. Packets are sent between the file server and Workstation B through the Access Points (root unit and remote node) over the radio link. Data packets sent from the file server to Workstation A go through the wired LAN segment and do not go across the wireless radio link.
Appendix A Supporting Mixed Network Topologies Aironet Access Points can be used to link different LANs in the same building. The example below illustrates a LAN to LAN connection within a building.
Appendix A To support mixed topologies, a Token Ring Access Point would be installed to support a local Token Ring network and an Ethernet Access Point would be installed to support a local Ethernet network. In a mixed environment, the Token Ring must be the root unit. The Aironet Ethernet and Token Ring Access Points can then communicate with each other– linking both types of networks into a single LAN.
Appendix A Point-to-Multipoint LAN Connections When connecting three or more LANs, each building requires an Aironet Access Point and antenna. This is called a Multipoint Access Point Configuration. One Access Point is designated as the central site. Its antenna is configured to transmit and receive signals from Access Points at other locations within the facility. Generally, the central site is equipped with an omni-directional antenna that provides radio signal coverage in all directions.
Appendix A The following example shows a Point-to-Multipoint Configuration. Packets sent between Workstation A and Workstation B are forwarded by their respective Access Points to the root unit. Then the root unit forwards these packets to the appropriate Access Point for routing to the workstations. Packets sent between the file server and the remote workstations are routed through the root unit and the appropriate Access Point.
