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. See National Restrictions in this section for more information.If you still have questions regarding the compliance of Xirrus products or you cannot find the information you are looking for, please contact us at:Xirrus, Inc.370 North Westlake Blvd, Suite 200Westlake Village, CA 91362USATel: 1.805.497.0955Fax: 1.805.449.1180www.xirrus.com

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.

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.

$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.
