About This Guide This guide provides detailed instructions for installing, configuring, and troubleshooting the Extricom EXSW-800/1200/2400 WLAN switches and Extricom EXRP-20/40UltraThin™ Access Point (AP) . Audience This guide is intended for enterprise IT managers and system installers who are familiar with installing and configuring networks. Conventions This is a note. It provides additional information to users. - This is a caution.
! 2 The switch and AP enclosure must not be opened by anyone other than an authorized service representative. To comply with FCC RF exposure compliance requirements, maintain a minimal separation distance of at least 20 cm/8 inches between the AP and all persons. The switch contains an internal battery. Always replace the battery with the same type to avoid the risk of explosion. Dispose of used battery according to the instructions provided with the new battery.
Chapter 1 Introduction to the Extricom Wireless LAN System A Wireless Local Area Network (WLAN) based on the IEEE 802.11 standard enables laptops, PDAs, phones, and other “Wi-Fi” equipped devices to wirelessly connect to the enterprise network.
Figure 1. Two Channel Blanket Coverage The Extricom solution is based on a fully centralized WLAN architecture, in which the switch makes all of the decisions for packet delivery on the wireless network. In this configuration, the access points (APs) simply function as radios, with no software, storage capability, or IP address. Even the basics of connecting are different: clients associate directly with the switch, not with the AP.
Multi-Layer WLAN Using multiple radio Access Points, a single set of APs enables deployment of multiple highdata-rate channel blankets with overlapping coverage, resulting in multiplied aggregate capacity. Separate channel blankets also offer the unique ability to guarantee Quality of Service by physically segregating different user types, traffic, and roles onto different channels. Same band operation The Extricom WLAN system enables two WLAN channels, in the same band (e.g. Channel 1 and 6 in 2.
System redundancy Extricom enables full redundancy by connecting two switches in parallel to different APs over the same area. The switchover parameters are user-configurable, and the Active to Standby switchover is seamless to the user. SNMP traps The Extricom system supports SNMP traps, enabling the user to determine the status of the system, including the status of APs and Redundancy statuses.
Overview of the Extricom Switches The Extricom EXSW-800 the EXSW-1200 and the EXSW-2400 switches provide central control and configuration of the WLAN. The switches implement the Interference-Free architecture in the Extricom WLAN. The WLAN switches are connected to EXRP-20 or the EXRP-40 access points to form Extricom WALN network. The EXSW-800 switch can connect up to 8 EXRP-20 APs each with two 802.11a/b/g radios, to provide two channel blankets.
Figure 4. Extricom EXSW-800 Switch Configuring a switch and its associated set of APs is as simple as configuring a single traditional AP, greatly reducing the effort required to deploy and maintain the WLAN. The minimal configuration required for the switch is done via a dedicated secured Web interface.
Overview of the Extricom Access Point Extricom’s EXRP-20 and EXRP-40 UltraThin APs are high-bandwidth devices, containing standard 802.11 radio devices. The EXRP-20 contain two radio devices while the EXRP-40 contain four radio devices Since the APs have no software, they require no configuration. This makes them fully interchangeable, enabling truly plug-and-play installation. If stolen, the APs do not pose a security risk, since all encryption is performed in the switch.
Overview of the Extricom Repeater The EXRE-10 Power Over Ethernet (PoE) Range Extender is a unique product that doubles the standard range of PoE, from the baseline 100 meters to a full 200 meters. It can be used both as a standalone to extend the reach of PoE installations that are limited power source UL approved, and as a complement to Extricom’s award-winning Interference-Free™ Wireless LAN (WLAN) System.
A Typical Extricom Wireless Network Topology Extricom’s switch is connected to the wired LAN, and the APs spread throughout the enterprise. Figure 7 displays a typical Extricom enterprise topology, consisting of an Extricom switch and eight APs. Figure 7. Typical Extricom Typology Extricom uses standard WLAN protocols (IEEE 802.11). As a result, any 802.11a/b/g standard wireless device can work seamlessly with the Extricom system.
Chapter 2 Installing the Extricom WLAN System This chapter provides instructions for unpacking and installing the Extricom WLAN system. Unpacking the Extricom WLAN System The Extricom WLAN system is shipped with the following: One Extricom switch. CD which contains The Extricom WLAN System User Guide and Release Notes. APs (the number of APs is based on customer order and provided in separate boxes) are shipped as part of the overall order.
Determining the Location of the Extricom Access Points Before installing the switch and access points, plan the placement of the APs. Before permanently mounting the APs, it is recommended to test the network (using a laptop client) to identify potential coverage holes. If such a problem exists, relocate an AP or add additional APs to resolve the coverage hole. The APs should be placed in a stable, secure location, such as on top of a closet or bookshelf, or mounted on a wall.
