The outdoor mounting of the CMM4 requires the 600S SD , 200S SB, and in certain cases the
LCOM surge suppressor . The L - COM surge suppressor is used only if the Gigabit Ethernet port
is being used on the CMM4 switch. The L - COM surge suppressor can be installed in the CMM4
unit. The overall installation instructions are as follows:
• ground the 600S SD and the 200S SB to Earth Ground
• connect the protected side of the 200S SB to the AC power supply SGPN4076
• connect the protected side of the 600S SD to the network switch or router in the
communications hut.
• add drip loops at any point in the cabling where the cable changes direction.
NOTE
Additional L - COM considerations during installation: if the CMM4 unit is mounted on
the antenna and is located more that three feet away from the communications hut,
an additional L - COM surge suppressor must be installed.
