  • Page 24 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.

  • Page 25: Chapter 2: Hardware Installation

    Chapter 2: Hardware Installation To install the access point, follow the steps outlined below: 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.
  • Page 26 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.
  • Page 27 Hardware Installation Mounting Points Fastening Screw Align this tab with the Fastening Screw Mounting Slots Bracket 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.
  • Page 28 Hardware Installation 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).

    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 and RBT-4102-EU also provide repeater and bridging services that can be configured independently on either the 5 GHz or 2.4 GHz radio interfaces.

  • Page 30: Network Topologies

    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.
