Up to four 600SSH surge suppressors may be mounted in series on an Ethernet link without degrading the
link. The equivalent of a 600SSH 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 600SSH on each
port.
As an example, a typical installation might have properly-grounded 600SSH units within 3 ft of each AP and
additional properly-grounded 600SSH units on each Ethernet cable mounted outside at the point of cable
entry to a telecommunications hut that contains the CMM4.
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
PMP Solutions 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 58430/54430 SM and PTP 58230/54230 BH. 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.
