Canopy 400 Series OFDM AP and SM User Guide radar detection. "Whitening," a technique used to avoid self-interference on Canopy FSK radios is not offered as an option on the Canopy 400 Series radios, as whitening is not a technology applicable to an OFDM signal. 2.4 RELEASE NUMBERING The first generally fielded Canopy 400 Series release is Release 8.4.1. It provides the same features that are in Release 8.2.4 for Canopy FSK radios, plus the OFDM layer. To summarize, • Release 8.2.x runs on Canopy FSK radios. Release 8.4.x does not. • Release 8.4.x runs on Canopy 400 Series OFDM radios. Release 8.2.x does not • "Release 8.3" is not planned to be used for release numbering. 2.5 POWER AND GROUNDING The Canopy 400 Series uses a 30 VDC nominal power system, instead of the 24 VDC nominal power system used previously in standard Canopy. A new 30 VDC power supply is available for the CMMmicro, and a new 30 VDC nominal (specified and labeled as 29.5 VDC) power supply is available for the SM. The new 30 VDC power supplies can also be used for standard Canopy, and are replacing the 24 VDC power supplies in the Canopy product line. The Canopy 400 Series radios have slightly higher power use than standard Canopy radios, and the higher voltage is needed to carry the higher wattage on cable runs approaching the 100 meter (328 ft) maximum length. CMMmicro 24 VDC power supplies and the latest version of SM 24 VDC power supplies can power Canopy 400 Series radios for shorter runs. Earlier versions of SM 24 VDC power supplies, especially the earlier heavier transformers, cannot. The best practice is to use 30 VDC power supplies with Canopy 400 Series APs and SMs, and avoid potential issues and cable length specific engineering. Due to the full metallic connection to the tower or support structure through the AP's antenna, grounding of the AP radio and surge suppression at the AP is strongly recommended to suppress overvoltages and overcurrents, such as those caused by near-miss lightning. The AP provides a grounding lug for grounding to the tower or support structure. The 600SSC surge suppressor replaces earlier surge suppressors and should be used within 3 ft (1 m) of the AP. A pole mount kit is available for the 600SSC, and provides a grounding lug that can be used for terminating grounding straps from both the 600SSC and the AP. 2.6 ADMINISTRATION SYSTEMS Standard Canopy administration systems are used to support the Canopy 400 Series products, with the only requirement being that the administration systems must be at the appropriate release level: • Prizm 3.1 is the element management system for Canopy 400 Series products. In addition to managing and monitoring Canopy modules, Prizm 3.1 can be used to update them. • CNUT 3.1 (Canopy Network Update Tool) is the stand-alone update tool for Canopy 400 Series products for operators not using Prizm. 2.7 TECHNICAL DETAILS, SPECIFICATIONS, PERFORMANCE Technical details for the AP Model No. 5440AP include • Connectorized radio and connectorized antenna kitted together - N-type connector Version 1, April 2008 Page 9 of 40
