Canopy 400 Series OFDM AP and SM User Guide Figure 9: Ground lug highlighted on AP Unlike standard Canopy APs, the Canopy 400 Series AP have metal-to-metal contact from the tower or support structure, through the antenna, through the coax cable, to the radio. Due to this, to provide the best protection from near lightning hits, it is strongly recommended to install surge suppression at the AP. The 600SSC surge suppressor replaces earlier surge suppressors, and supports up to three 600SSCs on an Ethernet link in series, for example, a 600SSC within 3 ft (~1 m) of an AP, another 600SSC where the Ethernet cable enters a telecommunications hut, and the equivalent of a 600SSC built into each of the 8 ports on a CMM4. A pole mount kit, Model No. SGHN5169A, is available to facilitiate mounting the 600SSC close (within 3 ft or 1 m) of the AP. The CMMmicro uses a different protection scheme and and up to 3 600SSCs can be used in-line on Ethernet links terminated to the CMMmicro. 5.2 INSTALLING AN SM SM installation is very similar to installing standard Canopy SMs as described in the Canopy System Release 8 User Guide, with the differences outlined below. Use an SMMB2 SM mounting bracket, not an SMMB1 typically used with standard Canopy SMs. The Canopy 400 Series SM is heavier and has a higher windload than a standard SM, and so the stronger SMMB2 is required. The SMMB2 is the mounting arm used with Canopy 900 MHz integrated APs and SMs, and used with reflectors. Use dielectric grease on all connections and in all RJ-45 Ethernet connectors. (Dielectric grease is generally available in the trade, and is specially formulated so as to be uniformly nonconducting.) The best practice is to use enough grease to fill the RJ-45 female connector, and then insert the RJ-45 male connector and push the grease further into the Canopy unit and around the RJ-45 connector. Excess grease can be wiped over the connector area to provide some resistance to water ingress around the connector. Version 1, April 2008 Page 30 of 40
