Connect Ethernet cables as follows (see page
for typical diagrams and planning
information):
•
APs, BH10s, or BH20s (PTP 100 Series bridges), PTP 230 Series bridges: cable to
powered ports of the controller board. The controller board provides sync, power, and
surge suppression for these connections. If the CMM4 is mounted inside a building or
communications hut, a Cambium 600SS surge suppressor (model number 600SSC or
later) should be mounted outside the building or communications hut on each line at
the point of cable penetration to prevent over-voltages and over-currents from
entering the building and potentially damaging other electronic equipment.
•
Terrestrial feeds under 100 Mbps (10/100BaseT): cable to an unpowered port of the
controller board. The controller board provides surge suppression for these
connections. If the CMM4 is mounted inside a building or communications hut, a
Cambium 600SS surge suppressor (model number 600SSC or later) should be
mounted outside the building or communications hut on each line at the point of cable
penetration to prevent over-voltages and over-currents from entering the building and
potentially damaging other electronic equipment.
•
Terrestrial feeds over 100 Mbps (1000BaseT Gigabit Ethernet): cable directly to the
Gigabit port of the EtherWAN switch, and mount a Cambium PTP-LPU lightning
protection unit or equivalent
o
within 3 ft (1 m) of the CMM4 if the CMM4 is located outdoors
o
on the outside of the building or communications hut at the point of cable
penetration if the CMM4 is located indoors.
•
PTP 400 Series bridges: cable to an unpowered port of the controller board. If the
CMM4 is inside a building or communication hut, install the bridge’s PIDU (Powered
InDoor Unit) also inside the building, and install a Hyperlink Technologies AL-CAT6HP-
JW surge suppressor or equivalent on the outside of the building or communications
hut at the point of cable penetration. If the CMM4 is mounted outside, locate the PIDU
in a weather-tight enclosure within 3 ft (1 m) of the CMM4 and install a Hyperlink
Technologies AL-CAT6HP-JW surge suppressor or equivalent within 3 ft (1 m) of the
PIDU.
•
PTP 500 and 600 Series bridges: cable directly to the Gigabit port of the EtherWAN
switch. If the CMM4 is inside a building or communication hut, install the bridge’s
PIDU (Powered InDoor Unit) also inside the building, and install a Hyperlink
Technologies AL-CAT6HP-JW surge suppressor or equivalent on the outside of the
building or communications hut at the point of cable penetration. If the CMM4 is
mounted outside, locate the PIDU in a weather-tight enclosure within 3 ft (1 m) of the
CMM4 and install a Hyperlink Technologies AL-CAT6HP-JW surge suppressor or
equivalent within 3 ft (1 m) of the PIDU.

On the door label, record the MAC and IP addresses of the CMM4 and all connected
equipment.
6
Record also the MAC address of the EtherWAN switch.
