Wireless Array Configuring the Wireless Array179 Procedure for Configuring CDP Settings 1.Enable CDP: When CDP is enabled, the Array sends out CDP announcements of the Array’s presence, and gathers CDP data sent by neighbors. When disabled, it does neither. CDP is enabled by default. 2.CDP Interval: The Array sends out CDP announcements advertising its presence at this interval. The default is 60 seconds. 3.CDP Hold Time: CDP information received from neighbors is retained for this period of time before aging out of the Array’s neighbor list. Thus, if a neighbor stops sending announcements, it will no longer appear on the CDP Neighbors window after CDP Hold Time seconds from its last announcement. The default is 180 seconds. See Also CDP Neighbors Network Network Interfaces Network Statistics Wireless Array 180Configuring the Wireless Array Services This is a status-only window that allows you to review the current settings and status for services on the Array, including DHCP, SNMP, Syslog, and Network Time Protocol (NTP) services. For example, for the DHCP server, it shows each DHCP pool name, whether the pool is enabled, the IP address range, the gateway address, lease times, and the DNS domain being used. There are no configuration options available in this window, but if you are experiencing issues with network services, you may want to print this window for your records. Figure 107. Services The following sections discuss configuring services on the Array: “Time Settings (NTP)” on page 181 “NetFlow” on page 184 “Wi-Fi Tag” on page 185 Wireless Array Configuring the Wireless Array181 “Location” on page 186 “System Log” on page 188 “SNMP” on page 193 “DHCP Server” on page 196 Time Settings (NTP) This window allows you to manage the Array’s time settings, including synchronizing the Array’s clock with a universal clock from an NTP (Network Time Protocol) server. We recommend that you use NTP for proper operation of SNMP in XMS (the Xirrus Management System), since a lack of synchronization will cause errors to be detected. Synchronizing the Array’s clock with an NTP server also ensures that Syslog time-stamping is maintained across all units. It is possible to use authentication with NTP to ensure that you are receiving synchronization from a known source. For example, the instructions for requesting a key for the NIST Authenticated NTP server are available at  http://www.nist.gov/pml/div688/grp00/upload/ntp_instructions.pdf. The Array allows you to enter optional authentication information. Figure 108. Time Settings (Manual Time) Procedure for Managing the Time Settings 1.Current Array Date and Time: Shows the current time for your convenience. 2.Time Zone: Select the time zone you want to use (normally your local time zone) from the pull-down list. Wireless Array 182Configuring the Wireless Array 3.Auto Adjust Daylight Savings: Check this box if you want the system to adjust for daylight savings automatically, otherwise leave this box unchecked (default). 4.Use Network Time Protocol: select whether to set time manually or use NTP to manage system time. 5.Setting Time Manually a.Adjust Time (hrs:min:sec): If you are not using NTP, check this box if you want to adjust the current system time. When the box is checked, you may enter a revised time (hours, minutes, seconds, am/pm) in the corresponding fields. If you don’t want to adjust the current time, this box should be left unchecked (default). b.Adjust Date (month/day/year): If you are not using NTP, check this box if you want to adjust the current system date. When the box is checked, you may enter a revised date (month, day and year) in the corresponding fields. If you don’t want to adjust the current date, this box should be left unchecked (default). 6.Using an NTP Server a.NTP Primary Server: If you are using NTP, enter the IP address or domain name of the NTP server. Figure 109. Time Settings (NTP Time Enabled) Wireless Array Configuring the Wireless Array183 b.NTP Primary Authentication: (optional) If you are using authentication with NTP, select the type of key: MD5 or SHA1. Select None if you are not using authentication (this is the default). c.NTP Primary Authentication Key ID: Enter the key ID, which is a decimal integer. d.NTP Primary Authentication Key: Enter your key, which is a string of characters. e.NTP Secondary Server: Enter the IP address or domain name of an optional secondary NTP server to be used in case the Array is unable to contact the primary server. You may use the authentication fields as described above if you wish to set up authentication for the secondary server. See Also Express Setup Services SNMP System Log Wireless Array 184Configuring the Wireless Array NetFlow This window allows you to enable or disable the sending of NetFlow information to a designated collector. NetFlow is a proprietary but open network protocol developed by Cisco Systems for collecting IP traffic information. When NetFlow is enabled, the Array will send IP flow information (traffic statistics) to the designated collector. Figure 110. NetFlow NetFlow sends per-flow network traffic information from the Array. Network managers can use a NetFlow collector to view the statistics on a per-flow basis and use this information to make key decisions. Knowing how many packets and bytes are sent to and from certain IP addresses or across specific network interfaces allows administrators to track usage by various areas. Traffic flow information may be used to engineer networks for better performance. Procedure for Configuring NetFlow 1.Enable NetFlow: Select one of the Netflow versions to enable NetFlow functionality: v5, v9, or IPFIX. Internet Protocol Flow Information Export (IPFIX) is an IETF protocol (www.ietf.org) performing many of the same functions as Netflow. Choose Disable if you wish to disable this feature. 2.NetFlow Collector Host (Domain or IP): If you enabled NetFlow, enter the domain name or IP address of the colle…

All other trademarks and brand names are marks of their respective holders. All rights reserved. This document may not be reproduced or disclosed in whole or in part by any means without the written consent of Xirrus, Inc. Please see Warranty and License Agreements in the Wireless Array User’s Guide. Document Part Number: 812-0085-006 Revision C February, 2014 XR-2425H Quick Installation Guide XR-2425H Quick Installation Guide The XR-2425H Hardened Wireless Array provides Xirrus wireless technology in a hardened case for installation outdoors and in other harsh environments. This guide describes how to install the XR-2425H on a pole or wall and execute the initial power up of the Array. The pole or wall can be a structure that is installed at ground level or on a roof. The XR-2425H is not compatible with other Xirrus mounting options. For additional information, see the Wireless Array User’s Guide. This document is intended ONLY for XR-2425H model Arrays. For other XR models please see the Quick Installation Guide for that model series. 1) You Need the Following Items  Accessory Kit (included in each Wireless Array carton) includes:  Mounting bracket and four attachment screws  Grounding screw  Two watertight RJ connector assemblies  Appropriate tools, bands, screws, and/or anchors required for the desired mounting location (not provided with the Array).  Antennas for up to four radios, to be installed by a professional installer. Antennas must meet these criteria:  Omni-directional antenna gain must not exceed 5 dBi in 2.4 and 5 GHz bands.  Directional antenna gain must not exceed: - 12.1 dBi gain in 2.4 GHz band. - 11.2 dBi gain in 5150-5350 MHz band. - 11.1 dBi gain in 5470-5725 MHz band. - 11.0 dBi gain in 5725-5850 MHz band.  Furthermore, in DFS bands (5250-5350 MHz and 5470-5725 MHz) all antenna types must have at least 5 dBi gain. Note that this restricts omni-drictional antennas to those with exactly 5 dBi gain in DFS bands.  Grounding wire and lug  Workstation with a Web browser to configure the Wireless Array.  RJ-45 Ethernet connection(s) to your wired network.  Power—XR-2425H Arrays are powered via Power over Gigabit Ethernet (PoGE) using an outdoor-rated Ethernet Cat 5e or Cat 6 cable that also carries data traffic. Only Xirrus- supplied power injectors, or 802.3at PoE-compliant switches, may be used to power the XR- XR-2425H Quick Installation Guide - 2 - 2425H. The XR-2425H is powered by one injector port rated at 30W or higher. See the Installation Guide for your PoE device for more information. NOTE: Xirrus-supplied PoGE Injectors and switches must be installed and used indoors. 2) Choose a Suitable Location The XR-2425H is tested to IP65 water proof and dust proof requirements to protect against severely wet and dusty environments. For optimal placement, we recommend that a predictive survey be performed by a qualified Xirrus partner.  Choose a location that is not subjected to submersion.  Direct sunlight may raise the effective ambient temperature many degrees above air temperature. It is best to choose a location that has some protection from the sun.  The maximum cable length between the XR-2425H and the RJ-45 Ethernet Network is 100 meters. The PoGE Injector is not a repeater, so its location will not increase this distance.  The XR-2425H can operate from a Wireless Distribution System (WDS) link. However, the unit will need to be configured via the Ethernet connection prior to mounting and power must still be supplied via the RJ-45 Ethernet connector.  Keep the unit away from electrical devices or appliances that generate RF noise—at least 3 to 6 feet (1 to 2 meters). 3) Prepare a Ground Source Part of the mechanical installation is to ensure that the Array is grounded to earth ground to dissipate any static electric charge that may develop due to wind.  Determine a good electrical earth ground point near the Array mounting location. If an earth ground point is not available, consult an electrician to have one installed.  Before the Array is attached to a wall or pole, secure a grounding wire and lug to the Array with the provided screw in the location indicated by the arrow, below. Attach grounding wire and lug here XR-2425H Quick Installation Guide - 3 - 4) Attach the Mounting Plate to the Array The accessory kit includes a mounting plate. Mounting plate dimensions are included in the Drawings section at the end of this guide. The mounting plate can be used for wall or pole mounting by reversing the side of the plate exposed. Attach the mounting plate to the Array using the eight provided screws in the locations indicated below (secure in at least 4 places). For Wall Mounting: For Wall Mounting, position the bracket with the four slotted flanges pointed towards the Array, as shown below. For Pole Mounting: For Pole Mounting, position the bracket with the four slotted flanges pointed away from the Array, as shown below. 5) Mount the Array on a Pole or Wall 5a) Pole Mounting For pole mounting, Xirrus recommends using metal straps (not included with the Array). The metal straps can be obtained from BAND-IT-IDEX, Inc. (www.BAND-IT-IDEX.com ). See their web site for additional contact information. Complete the following steps to mount the Array to a pole.  Install the metal bands through the holes in the mounting bracket.  Note that the photos below show a different mounting bracket. The steps for installation are identical, however. XR-2425H Quick Installation Guide - 4 -  Hand tighten the Band-It strap through the pole mounting bracket, thread it through the strap buckle and then bend the strap back.  Using the Band-It tool, place the tool onto the strap.  Rotate the Band-It tool so that it can pull the excess strap through the buckle and turn the crank until the strap is very tight.  Onc…

The following page provides calculations for the power density 20cm from the system with the maximum number of radios in one band. The calculations are conservative as they assume all radios would be transmitting at 100% duty cycle and does not consider the separation distance between the individual radios' antennas.
