PMP 400 and PTP 200 Series
can be wiped over the connector area to provide some resistance to water ingress
around the connector.
3. Use a 600SSC surge suppressor within 3 ft (~1 m) of the AP, and ground it to known
good ground (Protective Earth - PE) on the tower or support structure with a 10 AWG
ground strap.
A pole mount kit is available for mounting the 600SSC to the tower or mast. The
mount includes a termination point for the ground strap from the 600SSC.
4. Run a 10 AWG ground strap from the grounding lug on the AP (see Figure 9) to
known good ground (Protective Earth - PE) to complete the grounding and protection
of the AP. The termination point on the 600SSC pole mount kit may be used for this.
=========================== end of procedure ======================
Unlike standard Canopy APs, the PMP 400 and PTP 200 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.
