L-COM Surge Suppressor installation
Chapter 3: CMM4 Hardware Installation
CAUTION
Observe caution when drilling through the wall of the building. Ensure that there are
no power lines, gas lines, water lines, or data lines in the wall at the desired location
where the drilling takes place.
Procedure 3-3 Surge suppressor installation and cable connections
1
Attach the surge suppressor to the communication hut near the cable access
point to the inside of the communications hut using two screws.
2
Remove the surge suppressor front cover to access the Ethernet RJ-45 jacks.
3
Connect the Ethernet cable from the CMM4 to the Ethernet port on the surge
suppressor port.
4
CAUTION
Follow local building codes for penetrating buildings. Observe
caution when drilling through the wall of the building. Ensure that
there are no power lines, gas lines, water lines, or data lines in
the wall at the desired location.
Drill a 3/4 inch (18 mm) hole through the wall of the communications hut at
the desired location.
5
Connect the Ethernet cable from the network or switch router from the
communications hut to the Ethernet port on the 600SSD surge suppressor.
6
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 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.
7
Ground the surge suppressor to Earth Ground.
8
Install the surge suppressor front cover to the base of the unit ensuring that
the cables are all routed through the cable slots.
L-COM Surge Suppressor installation
The L-COM surge suppressor is used only when the Gigabit Ethernet port is used on the CMM4
switch. The L-COM must be installed inside the CMM4 unit, or inside the communication’s hut,
this item is never installed outdoors.
