It should be powered by PoE (Power over Ethernet) using a weatherized Ethernet cable. A mid-span PoE injector is provided with the ES2440. This mid-span PoE injector, as well as the power supply/adapter used to power that injector, should remain indoors, protected from the weather. From the mid-span PoE injector, a weatherized Ethernet cable should be run to the outdoor ES2440. In this way, power can be safely provided to the outdoor ES2440 while the power supply and injector remain protected indoors, as shown: The power port on the ES2440 should not be used; it is reserved for future expansion. Weatherized Ethernet Cable PoE Midspan Injector ES2440 Wall Outlet Ethernet QA review draft1 ES2440 Hardware Guide ii IMPORTANT FCC INFORMATION The Federal Communications Commission has released Office of Engineering and Technology Laboratory Division Knowledge Database (KDB) 44399, which refines the definition of Dynamic Frequency Selection (DFS) support. Since this device has the ability to use frequencies covered by DFS, KDB 443999 must be followed. It is published in full on the FCC web site: https://apps.fcc.gov/oetcf/kdb/forms/FTSSearchResultPage.cfm?switch=P&id=41732 In order to support FCC KDB 443999, Fortress has limited the use of certain frequencies within the 5400–5725 MHz range. Specifically, the frequencies defined by the FCC as being of primary interest are those in the 5600–5650 MHz range, which correspond to 802.11a channels 120, 124, and 128. In order to comply with the KDB 443999, these channels have been removed from use, or notched. Notched channels are unavailable for use on this device. KDB 44399 provides additional restrictions on the use of channels within 30 MHz of notched channels when the device is within 35 km of a Terminal Doppler Weather Radar (TDWR) installation. Affected channels 116, 132, and 136 serve as a guard of 30 MHz around the critical notched frequencies. Guard frequencies are unavailable for use on this device by default. The FCC allows these channels to be used, however, as long as the device is not within 35 km of a TDWR installation, as described in this excerpt of KDB 443999: Any installation of either a master or a client device within 35 km of a TDWR location shall be separated by at least 30 MHz (center-to-center) from the TDWR operating frequency. In some instances it is possible that a device may be within 35 km of multiple TDWRs. In this case the device must ensure that it avoids operation within 30 MHz for each of the TDWRs. This requirement applies even if the master is outside the 35 km radius but communicates with outdoor clients which may be within the 35 km radius of the TDWRs. The requirement for ensuring 30 MHz frequency separation is based on the best information available to date. If interference is not eliminated, a distance limitation based on line-of-sight from TDWR will need to be used. Please refer to the original KDB 443999 as posted on the FCC web site for the complete text. In order to enable channels 116, 132, and/or 136, please contact Fortress to obtain a special license. This license will be issued after it is confirmed that the installation is not within 30 MHz and 35 km of registered TDWR sites. The following table (provided by the FCC in KDB 443999 published on 10/14/2010) describes the locations of TDWR sites, as well as the frequencies at which these sites operate: TDWR Location InformationTERRAIN ELEVATION (MSL) [ft] ANTENNA HEIGHT ABOVE TERRAIN [ft] STATE CITY LONGITUDE LATITUDE FREQUENCY AZ PHOENIX W 112 09 46 N 33 25 14 5610 MHz 1024 64 CO DENVER W 104 31 35 N 39 43 39 5615 MHz 5643 64 FL FT LAUDERDALE W 080 20 39 N 26 08 36 5645 MHz 7 113 FL MIAMI W 080 29 28 N 25 45 27 5605 MHz 10 113 FL ORLANDO W 081 19 33 N 28 20 37 5640 MHz 72 97 FL TAMPA W 082 31 04 N 27 51 35 5620 MHz 14 80 FL WEST PALM BEACH W 080 16 23 N 26 41 17 5615 MHz 20 113 GA ATLANTA W 084 15 44 N 33 38 48 5615 MHz 962 113 IL MCCOOK W 087 51 31 N 41 47 50 5615 MHz 646 97 IL CRESTWOOD W 087 43 47 N 41 39 05 5645 MHz 663 113 IN INDIANAPOLIS W 086 26 08 N 39 38 14 5605 MHz 751 97 KS WICHITA W 097 26 13 N 37 30 26 5603 MHz 1270 80 KY COVINGTON CINCINNATI W 084 34 48 N 38 53 53 5610 MHz 942 97 KY LOUISVILLE W 085 36 38 N 38 02 45 5646 MHz 617 113 LA NEW ORLEANS W 090 24 11 N 30 01 18 5645 MHz 2 97 QA review draft1 ES2440 Hardware Guide ii…
