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, you are encouraged to try to correct the interference by one or more of the following measures:zReorient or relocate the receiving antenna.zIncrease the separation between the equipment and the receiver.zConsult the dealer or an experienced wireless technician for help.Use of a shielded twisted pair (STP) cable must be used for all Ethernet connections in order to comply with EMC requirements.RF Radiation Hazard WarningTo ensure compliance with FCC RF exposure requirements, this device must be installed in a location where the antennas of the device will have a minimum distance of at least 25 cm (9.84 inches) from all persons. Using higher gain antennas and types of antennas not certified for use with this product is not allowed. The device shall not be co-located with another transmitter.
Non-Modification StatementUnauthorized changes or modifications to the device are not permitted. Use only the supplied internal antenna, or external antennas supplied by the manufacturer. Modifications to the device will void the warranty and may violate FCC regulations. Please go to the Xirrus Web site for a list of all approved antennas.Indoor UseThis product has been designed for indoor use. Operation of channels in the 5150MHz to 5250MHz band is permitted indoors only to reduce the potential for harmful interference to co-channel mobile satellite systems.Cable Runs for Power over Gigabit Ethernet (PoGE)If using PoGE, the Array must be connected to PoGE networks without routing cabling to the outside plant—this ensures that cabling is not exposed to lightning strikes or possible cross over from high voltage.Battery WarningCaution! The Array contains a battery which is not to be replaced by the customer. Danger of Explosion exists if the battery is incorrectly replaced. Replace only with the same or equivalent type recommended by the manufacturer. Dispose of used batteries according to the manufacturer's instructions.Power CordIf you will be using the Array with a power cord, you must use a UL-Approved cord. Order the power cord from the Xirrus product list—Xirrus supplies only UL-approved power cords. Maximum Antenna GainCurrently, the maximum antenna gain for external antennas is limited to 2.5dBi for operation in the 5150MHz to 5250MHz and 5725MHz to 5825MHz bands. The antenna gains must not exceed maximum EIRP limits set by the FCC / Industry Canada.High Power RadarsHigh power radars are allocated as primary users (meaning they have priority) in the 5150MHz to 5250MHz and 5725 MHz to 5825MHz bands. These radars could cause interference and/or damage to LELAN devices used in Canada.
Industry Canada Notice and MarkingThis Class A digital apparatus complies with Canadian ICES-003.Cet appareil numérique de la classe A est conforme à la norme NMB-003 du Canada.The term “IC:” before the radio certification number only signifies that Industry Canada technical specifications were met.To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (EIRP) is not more than that required for successful communication.

Unless this wireless LAN product is operating within the boundaries of the owner’s property, its use requires a “general authorization.” Please check with www.communicazioni.it/it/ for more details.Questo prodotto é conforme alla specifiche di Interfaccia Radio Nazionali e rispetta il Piano Nazionale di ripartizione delle frequenze in Italia. Se non viene installato all’interno del proprio fondo, l’utilizzo di prodotti wireless LAN richiede una “autorizzazione Generale.” Consultare www.communicazioni.it/it/ per maggiori dettagli.Norway, Switzerland and LiechtensteinAlthough Norway, Switzerland and Liechtenstein are not EU member states, the EU Directive 1999/5/EC has also been implemented in those countries.Calculating the Maximum Output Power The regulatory limits for maximum output power are specified in EIRP (radiated power). The EIRP level of a device can be calculated by adding the gain of the antenna used (specified in dBi) to the output power available at the connector (specified in dBm).
AntennasThe Xirrus Wi-Fi Array employs integrated antennas that cannot be removed and which are not user accessible. Nevertheless, as regulatory limits are not the same throughout the EU, users may need to adjust the conducted power setting for the radio to meet the EIRP limits applicable in their country or region. Adjustments can be made from the product’s management interface—either Web Management Interface (WMI) or Command Line Interface (CLI).Operating FrequencyThe operating frequency in a wireless LAN is determined by the access point. As such, it is important that the access point is correctly configured to meet the local regulations.

Wi-Fi Array6 Introductionthe term Window when referring to how the Wi-Fi Array’s Web Management Interface is displayed on your monitor.Why Choose the Xirrus Wi-Fi Array?The deployment of wireless LANs is becoming increasingly common as businesses strive for greater flexibility in the workplace and the need for employee mobility rises. The only requirements for an effective wireless deployment are a power source, a couple of screws, and a little imagination.Wireless LAN is also fully compatible with standard Ethernet protocols, so connectivity with existing wired infrastructures is transparent to users—they can still access and use the same applications and network services that they use when plugged into the company’s wired LAN infrastructure (it’s only the plug that no longer exists).Wireless LAN has come a long way in the past few years and now offers the performance, reliability and security that Enterprise customers have come to expect from their networks. The technology is being driven by three major IEEE standards:z802.11aOperates in the 5 GHz range with a maximum speed of 54 Mbps. z802.11bOperates in the 2.4 GHz range with a maximum speed of 11 Mbps. z802.11gSupports a transmission speed of 54 Mbps in the 2.4 GHz range and is backwards compatible with 802.11b.z802.11nSupports a higher transmission speed of up to 300 Mbps in the 5 GHz range and is backwards compatible with 802.11a/b/g.Whether you’re a small company with just a handful of employees, or a large corporation with thousands, wireless has the scalability and flexibility to serve your needs.

Wi-Fi ArrayInstalling the Wi-Fi Array 27Installing the Wi-Fi ArrayThe instructions for completing a successful installation include the following topics:z“Installation Prerequisites” on page 27.z“Planning Your Installation” on page 30.z“Installation Workflow” on page 49.z“Unpacking the Wi-Fi Array” on page 50.z“Installing Your Wi-Fi Array” on page 52.z“Powering Up the Wi-Fi Array” on page 73.z“Establishing Communication with the Array” on page 76.z“Performing the Express Setup Procedure” on page 77.Installation PrerequisitesYour Wi-Fi Array deployment requires the presence of hardware and services in the host wired/wireless network, including:zDedicated AC power outletUnless you are using Xirrus PoGE, you need a dedicated power outlet to supply AC power to each unit deployed at the site. If you are using the optional PoGE, then power is supplied over the same Cat 5e or Cat 6 cable used for data. PoGE power injector modules are available in 1 port and 8 port configurations and are typically placed near your Gigabit Ethernet switch. An AC outlet is required for each injector module.zEthernet port You need at least one 100/1000 BaseT port to establish wired Gigabit Ethernet connectivity (via the product’s Gigabit 1 or Gigabit 2 port) and one 10/100 BaseT port (if desired) for product management. !The Array’s Ethernet ports should be connected to an Ethernet switch, not an Ethernet hub—if a hub is used, we recommend that you connect only one Ethernet port.
Wi-Fi Array28 Installing the Wi-Fi ArrayzSecure Shell (SSH) utilityTo establish secure remote command line access to the Array, you need a Secure Shell (SSH) utility, such as PuTTY.zSecure Web browserEither Internet Explorer (version 6.0 or higher), Netscape Navigator (version 7.0 or higher), or Mozilla Firefox (version 1.01 or higher).A secure Web browser is required for Web-based management of the Array. The browser must be on the same subnet as the Array, or you must set a static route for management as described in the warning above. zSerial connection capabilityTo connect directly to the console port on the Array, your computer must be equipped with a male 9-pin serial port and terminal emulation software (for example, HyperTerminal). The Xirrus Array only supports serial cable lengths up to 25’ per the RS-232 specification. Use the following settings when establishing a serial connection:!The Gigabit1 Ethernet interface is the primary port for both data and management traffic. If a single Ethernet connection is used, it must be connected to the Gigabit1 Ethernet interface. See also, “Port Failover Protection” on page 40.The 10/100 Ethernet Port may be used for managing the Array out of band from the Gigabit Ethernet ports. The 10/100 port will route only management traffic, using a static route that may be configured for this interface. See “interface” on page 273.

The 8 Port Injector provides distributed power to multiple Arrays, eliminating the need to run dedicated AC power to each unit and facilitating backup power when connected via a UPS.Specific models of the Array are compatible with specific PoGE modules. For details, please see “Contact Information” on page 349. zExternal RADIUS serverAlthough your Array comes with an embedded RADIUS server, for 802.1x authentication in large deployments you may want to add an external RADIUS server.Client RequirementsThe Wi-Fi Array should only be used with Wi-Fi certified client devices.See AlsoCoverage and Capacity PlanningDeployment ExamplesFailover PlanningPlanning Your Installation
Wi-Fi Array30 Installing the Wi-Fi ArrayPlanning Your InstallationThis section provides guidelines and examples to help you plan your Xirrus Wi-Fi Array deployment to achieve the best overall coverage and performance. We recommend you conduct a site survey to determine the best location and settings for each Array you install.General Deployment ConsiderationsThe Wi-Fi Array’s unique multi-radio architecture generates 360 degrees of sectored high-gain 802.11a/b/g/n coverage that provides extended range. However, the number, thickness and location of walls, ceilings or other objects that the wireless signals must pass through may affect the range. Typical ranges vary depending on the types of materials and background RF (radio frequency) noise at your location. To maximize wireless range, follow these basic guidelines:1. Keep the number of walls and ceilings between the Array and your receiving devices to a minimum—each wall or ceiling can reduce the wireless range from between 3 and 90 feet (1 to 30 meters). Position your devices so that the number of walls or ceilings is minimized.2. Be aware of the direct line between each device. For example, a wall that is 1.5 feet thick (half a meter) at 90° is actually almost 3 feet thick (or 1 meter) when viewed at a 45° angle. At an acute 2° degree angle the same wall is over 42 feet (or 14 meters) thick! For best reception, try to ensure that your wireless devices are positioned so that signals will travel straight through a wall or ceiling.Figure 8. Wall Thickness Considerations90° 45°1.5 feet/ .5 m ~ 3 feet/ 1 m> 42 feet\ 14 m2°

Try to position wireless client devices so that the signal passes through drywall (between studs) or open doorways and not other materials that can adversely affect the wireless signal.See AlsoCoverage and Capacity PlanningDeployment ExamplesDeployment SummaryInstallation Prerequisites
Wi-Fi Array32 Installing the Wi-Fi ArrayCoverage and Capacity PlanningThis section considers coverage and capacity for your deployment(s), including placement options, RF patterns and cell sizes, area calculations, roaming considerations, and channel allocations.PlacementUse the following guidelines when considering placement options:1. The best placement option for the Array is ceiling-mounted within an open plan environment (cubicles rather than fixed walls).2. Keep the Array away from electrical devices or appliances that generate RF noise. Because the Array is generally mounted on ceilings, be aware of its position relative to lighting (especially fluorescent lighting)—we recommend maintaining a distance of at least 3 to 6 feet (1 to 2 meters).3. If using multiple Arrays in the same area, maintain a distance of at least 100 ft/30m between Arrays if there is direct line-of-sight between the units, or at least 50 ft/15m if a wall or other barrier exists between the units.Figure 9. Unit Placement100 ft/ 30m100 ft/ 30 m100 ft/30 m
Wi-Fi ArrayInstalling the Wi-Fi Array 33RF PatternsThe Wi-Fi Array allows you to control—automatically or manually—the pattern of wireless coverage that best suits your deployment needs. You can choose to operate with full coverage, half coverage, or custom coverage (by enabling or disabling individual sectors).Full (Normal) CoverageIn normal operation, the Array provides a full 360 degrees of coverage.Figure 10. Full (Normal) CoverageHalf CoverageIf installing a unit close to an exterior wall, you can deactivate half of the radios to prevent redundant signals from “bleeding” beyond the wall and extending service into public areas. The same principle applies if you want to restrict service to an adjacent room within the site.Figure 11. Adjusting RF Patternsoutside wall
Wi-Fi Array34 Installing the Wi-Fi ArrayCustom CoverageWhere there are highly reflective objects in close proximity to the Array, you can turn off specific radios to avoid interference and feedback.Figure 12. Custom CoverageCapacity and Cell SizesCell sizes should be estimated based on the number of users, the applications being used (for example, data/video/voice), and the number of Arrays available at the location. The capacity of a cell is defined as the minimum data rate desired for each sector multiplied by the total number of sectors being used.Figure 13.

Wi-Fi ArrayInstalling the Wi-Fi Array 35Figure 13 shows some sample maximum connection rates for the XN8 and XN16 at different distances in an unobstructed area.  Wireless environments can vary greatly so the actual rates may be different depending on the specific network deployment. Fine Tuning Cell SizesAdjusting the transmit power allows you to fine tune cell sizes. There are four standard sizes—Small, Medium, Large, or Max (the default is Max). There is also an Auto setting that automatically determines the best cell size, and a Manual setting that allows you to choose your power settings directly. If you are installing many units in close proximity to each other, reduce the transmit power to avoid excessive interference with other Arrays or installed APs. See also, “Coverage and Capacity Planning” on page 32.Figure 14.

Roaming ConsiderationsCells should overlap approximately 10 - 15% to accommodate client roaming.Figure 15. Overlapping CellsAllocating ChannelsBecause the Wi-Fi Array is a multi-channel device, allocating the best channels to radios is important if peak performance is to be maintained.Automatic Channel SelectionWe recommend that you allow the Array to make intelligent channel allocation decisions automatically. In the automatic mode, channels are allocated dynamically, driven by changes in the environment.ROAMING10 - 15% overlap

Wi-Fi Array42 Installing the Wi-Fi ArrayPower PlanningThe XN8 and XN16 Array models and all four-port Arrays support both AC power and Power over Gigabit Ethernet (PoGE). This section discusses the AC and PoGE power options.AC PowerThe AC power option requires a direct connection between the Array and a dedicated AC power outlet. The power cord is provided with the unit.Power over Gigabit EthernetTo deliver power to the Array, you may use the optional XP1 or XP8 Power over Gigabit Ethernet (PoGE) modules. They provide power over Cat 5e or Cat 6 cables to the Array without running power cables—see Figure 4 on page 10. Specific models of the Array are compatible with specific PoGE modules. For details, please see “Contact Information” on page 349. See AlsoCoverage and Capacity PlanningDeployment ExamplesFailover PlanningNetwork Management PlanningSecurity PlanningSecurity PlanningThis section offers some useful guidelines for defining your preferred encryption and authentication method. For additional information, see “Understanding Security” on page 165 and the Security section of “Frequently Asked Questions” on page 334.Wireless EncryptionEncryption ensures that no user can decipher another user’s data transmitted over the airwaves. There are three encryption options available to you, including:#When using Cat 5e or Cat 6 cable, power can be provided up to a distance of 100m.
Wi-Fi ArrayInstalling the Wi-Fi Array 43zWEP-40bit or WEP-128bitBecause WEP is vulnerable to cracks, we recommend that you only use this for legacy devices that cannot support a stronger encryption type.zWi-Fi Protected Access (WPA)This is much more secure than WEP and uses TKIP for encryption.zWi-Fi Protected Access (WPA2) with AES This is government-grade encryption—available on most new client adapters—and uses the AES–CCM encryption mode (Advanced Encryption Standard–Counter Mode).AuthenticationAuthentication ensures users are who they say they are, and occurs when users attempt to join the wireless network and periodically thereafter. The following authentication methods are available with the Wi-Fi Array:zRADIUS 802.1x 802.1x uses a remote RADIUS server to authenticate large numbers of clients, and can handle different authentication methods (EAP-TLS, EAP-TTLS, EAP-PEAP, and EAP-LEAP Passthrough).zXirrus Internal RADIUS serverRecommended for smaller numbers of users (about 100 or less). Supports EAP-PEAP onlyzPre-Shared KeyUses a pass-phrase or key that is manually distributed to all authorized users. The same passphrase is given to client devices and entered into each Array.zMAC Access Control Lists (ACLs)MAC access control lists provide a list of client adapter MAC addresses that are allowed or denied access to the wireless network, and can be used in addition to any of the above authentication methods. ACLs are good for embedded devices, like printers and bar-code scanners (though MAC addresses can be spoofed). The Wi-Fi Array supports 1,000 ACL entries.

Wi-Fi Array46 Installing the Wi-Fi ArrayWDS PlanningWDS (Wireless Distribution System) creates wireless backhauls between arrays, allowing your wireless network to be expanded using multiple Arrays without the need for a wired backbone to link them (see Figure 22). WDS features include:zOne to three IAPs may be used to form a WDS link, yielding up to 162 Mbps bandwidth per link. Up to 4 WDS links may be defined per Array.zAutomatic IAP Load Balancing zClients can still associate to a BSS on the same radio interface used for a WDS Host Link. This will take bandwidth from the WDS link. Figure 22. WDS LinkzMultiple links per Array allow you to configure multi-hop connections.Figure 23. A Multiple Hop WDS Connection
Wi-Fi ArrayInstalling the Wi-Fi Array 47zMultiple WDS links can provide link redundancy (failover capability - see Figure 24). A network protocol (Spanning Tree Protocol—STP) prevents Arrays from forming network loops. Figure 24. WDS Failover ProtectionWDS links have a Host/Client relationship similar to the usual IAP/station pattern for Arrays:zA WDS Client Link associates/authenticates to a host (target) Array in the same way that a station associates to an IAP. The client side of the link must be configured with the root MAC address of the target (host) Array.zA WDS Host Link acts like an IAP by allowing one WDS Client Link to associate to it. An Array may have both client and host links.WDS configuration is performed only on the client-side Array. See “WDS” on page 229. Note that both Arrays must be configured with the same SSID name.

The Wi-Fi Array was designed to be mounted on a ceiling where the unit is unobtrusive and wireless transmissions can travel unimpeded throughout open plan areas.You also have the option of mounting the Array on a wall, using the optional wall mount assembly kit. For wall mount instructions, go to “Mounting the Array on a Wall (XN16/XN8)” on page 62.Choose a location that is central to your users (see the following diagram for correct placement.Figure 26.

Wi-Fi ArrayInstalling the Wi-Fi Array 53Wiring ConsiderationsUnless you are using the Xirrus Power over Gigabit Ethernet modules (PoGE) with an Array that supports PoGE, an AC power outlet must be available to the Array. If you are using PoGE to distribute power, see “Power over Gigabit Ethernet (PoGE) (Optional)” on page 10.Once you have determined the best location for your Wi-Fi Array, you must run cables to the location for the following services:PowerOne of the following options:zNo power cable is required if using PoGE modules. zDedicated AC power if PoGE is not in use. You must use a UL-approved cord. Order the power cord from the Xirrus product list—Xirrus supplies only UL-approved power cords. NetworkzGigabit 1—If using PoGE modules, the Cat 5e or Cat 6 cable from the Gigabit Ethernet switch to the Array must be less than 100m long. The Array must be connected to PoGE networks without routing cabling to the outside plant, to ensure that cabling is not exposed to lightning strikes or possible high voltage crossover.zGigabit 2 (optional)zFast Ethernet (optional)zSerial cable— cable lengths up to 25’ per the RS-232 specification.Important Notes About Network ConnectionsRead the following notes before making any network connections.#When the unit’s IP address is unknown or a network connection has not been established, the serial cable is used for connecting directly with the Command Line Interface (CLI) via HyperTerminal. When a network connection is established, the Array can be managed from any of the available network connections, either Fast Ethernet, Gigabit 1 or Gigabit 2.

The Wi-Fi 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). Once the unit is mounted it can be removed and re-attached easily, without the need for tools or modifications to the original installation.This section assumes that you are mounting the Array to a tiled ceiling. If your ceiling is not tiled, the mounting plate can be attached directly to the ceiling with the screws and anchors provided (without using the tile grid mounting clamps).!The Array’s Ethernet ports should be plugged into an Ethernet switch, not an Ethernet hub—if a hub is used, we recommend that you connect only one Ethernet port.!The Gigabit1 Ethernet interface is the primary port for both data and management traffic. If a single Ethernet connection is used, it must be connected to the Gigabit1 Ethernet interface. See also, “Port Failover Protection” on page 40.The 10/100 Ethernet Port may be used for managing the Array out of band from the Gigabit Ethernet ports. The 10/100 port will route only management traffic, using a static route that may be configured for this interface. See “interface” on page 273.
Wi-Fi ArrayInstalling the Wi-Fi Array 55Attaching the T-Bar Clips to the TemplateThe T-bar clips are used to create four mounting points on the ceiling tile grid for the Array mounting plate. Use the mounting template (provided) to find the correct location for all four clamps by pre-loading the 4 T-bar clips through the holes in the mounting template. Twist the clips until they are correctly aligned with the markings on the template.Figure 27. Attaching the T-Bar Clips to the Template Secure the T-Bar Clips to the Ceiling Support GridThe mounting template should be oriented so that the Array’s abg2 omni-directional monitoring IAP (radio) is pointing in the direction of the least required wireless signal coverage—for example, a nearby exterior wall or entrance.Use the mounting template to find the correct location for all four T-bar clips, then twist the clips onto the metal ceiling support grid and tighten the screw posts to 10-12 lbf.ft (1.38-1.66 kgf.m). See Figure 28. Do not overtighten the screw posts.
