Page 36: Introduction
There are three versions of this product, each with a different wireless capacity—16 IAPs (Integrated Access Points—radios) with the XS-3900, 8 IAPs with the XS-3700, and 4 IAPs with the XS-3500. Xirrus Wireless Management System (XM-3300) The XM-3300 is used for managing large Wireless WLAN Array deployments from a centralized Web-based interface.
Page 37: Nomenclature
Throughout this User’s Guide, the Wireless LAN Array is also referred to as the Xirrus Array, or simply the Array. In some instances, the terms product and unit are also used. When discussing specific products from the Xirrus family, the product name is used (for example, XS-3900, XS-3700 or XS-3500).

Page 40: Why Choose The Xirrus Wireless Lan Array
Wireless LAN Array Why Choose the Xirrus Wireless LAN Array? In 2003 there were approximately 30,000 Wireless Local Area Networks (WLANs) operating in the public domain. Research suggests that the number will more than quadruple by 2006. Enterprise WLANs in the private sector are also becoming increasingly common as businesses strive for greater flexibility in the workplace and the need for employee mobility rises.
Page 41: Product Overview
Wireless LAN Array Product Overview Part of the family of Xirrus products, the Wireless LAN Array is a high capacity, multi-mode device designed for the Enterprise market, with twice the range and up to sixteen times the capacity of competitive wireless products.
Page 42: Deployment Flexibility
Array. Partial pattern coverage If desired, the Xirrus Array can be deployed close to an exterior wall. In this case, half of all available radios have been deactivated to prevent redundant signals from “bleeding” beyond the site’s perimeter wall. This configuration may also be used in those cases where you want to restrict wireless coverage to selected areas of the building’s interior.
Page 43: Remote Dc Power System (Optional)
Array (DC version) deployments, eliminating the need to provide an AC power outlet in close proximity to the unit(s). In the following example, DC power is supplied to four Xirrus Arrays while utilizing only one AC power outlet.
Page 44: Enterprise Class Management
Wireless LAN Array Enterprise Class Management The Xirrus Array can be configured with its default RF settings, or the RF settings can be customized using the Array’s embedded Web Management Interface (WMI). The WMI enables easy configuration and control from a graphical console, along with a full compliment of troubleshooting tools, reports and statistics.
Page 45: Key Features And Benefits
Wireless LAN Array Key Features and Benefits This section describes some of the key product features and the benefits you can expect when deploying the Xirrus Array (the XS-3900 product is highlighted in this section). High Capacity and High Performance The XS-3900 easily handles time-sensitive traffic, such as voice, and can enable wireless connectivity for 1,024 users.
Page 46: Extended Coverage
Wireless LAN Array Extended Coverage One XS-3900 solution enables you to replace up to sixteen access points (includes one omnidirectional IAP for monitoring the network). Fifteen IAP radios with integrated directional antennas provide increased wireless range and enhanced data rates in all directions. With a Xirrus Array deployed, far fewer access points are needed for your wireless network.
Page 47: Non-Overlapping Channels
Non-Overlapping Channels Complete use of non-overlapping channels limits interference and delivers maximum capacity. On the XS-3900, all 16 non-overlapping channels are fully utilized across the 5GHz and 2.4GHz spectrums (up to 12 across the 5GHz spectrum and up to 3 across the 2.4GHz spectrum—typically, one radio is used as a dedicated RF monitor).

Unless you are using the Xirrus Remote DC Power System (XP-3100) with the DC version of the Xirrus Array, you need a dedicated power outlet to supply AC power to each unit deployed at the site. If you are using the optional XP-3100, then DC power is supplied to all units and only one AC outlet is required for the XP-3100.

Most offices have drop-down acoustical ceiling tiles set into a standard grid. The Xirrus Array has been designed to enable mounting to a tiled ceiling via a mounting plate and clamps that attach to the grid. Once the mounting plate is attached, the Array simply rotates onto the plate (similar to a smoke detector).
Page 79: Attaching The T-Bar Clips

Page 100: The Web Management Interface
Interface (WMI), used for establishing your network’s configuration settings and wireless operating parameters. An Overview The WMI is an easy-to-use graphical interface to your Xirrus Array. It allows you to configure the product to suit your individual requirements and ensure that the unit functions efficiently and effectively.
Page 101: Content
Wireless LAN Array Content The content of the WMI has been organized by function and hierarchy, shown here in list form. You can click on any item in the list to jump to the referenced destination. Array Status Express Setup Network Interfaces Network Settings Network Statistics...
Page 102: Structure
Wireless LAN Array Structure The WMI has been designed with simplicity in mind, making navigation quick and easy. In the following example, you’ll see that pages are divided into left and right frames. The left frame contains configuration elements organized by function (for example, radio interfaces, security, etc.), and where these functions are sub-divided there is an associated pull-down menu.
Page 103: Status Bar
Wireless LAN Array Status Bar Below the configuration frames you will find a status bar containing information about this Array, including: Location—displays the location information assigned to the unit. Host name—the host name assigned to this unit. Network interface IP address—the IP address of the network interface that is currently being used.

This chapter covers configuration and management tasks using the product’s embedded Web Management Interface (WMI). It also includes a procedure for logging in to the XS-3900/XS-3700/XS-3500 with your Web browser. Section headings for this chapter include: “Logging In” on page 69 “Making Configuration Changes to the Array”...
Page 105: Making Configuration Changes To The Array
Array Status This is a status only page that provides a snapshot of the global configuration settings for all XS-3900/XS-3700/XS-3500 network interfaces and radios. You must go to the appropriate configuration page to make changes to any of the settings displayed here (configuration changes cannot be made from this page).
