Install a 600SS surge suppressor within 3 ft (~1 m) of an AP or BH. A pole mount kit for the
600SS is shown in Figure 15 to facilitate installation of the 600SS by the AP or BH.
Up to four 600SS surge suppressors may be mounted in series on an Ethernet link without
degrading the link. The equivalent of a 600SS is built into each of the 8 ports on a CMM4 and
counts as one of the four. The CMMmicro uses a different protection scheme and does not have
the equivalent of a 600SS on each port.
As an example, a typical installation might have properly-grounded 600SS units within 3 ft of each
AP and additional properly-grounded 600SS units on each Ethernet cable mounted outside at the
point of cable entry to a telecommunications hut that contains the CMM4.
5.2 INSTALLING AN SM OR BH WITH AN INTEGRATED ANTENNA
Installing an SM or BH with an integrated antenna 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 for the PMP 54400 and 49400 SM and a SMMB1 mounting
bracket for the PMP 58430 SM. The PMP 400 Series SM or the PTP 200 Series BH is heavier
and has a higher wind load than a classic Canopy module, 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 (which is uniformly non-conducting) on all connections and in all RJ-45
Ethernet connectors. 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.
