CMM4
(Continued)
4
Stagger
the
cables
as
shown
in
the
figure
to
make
it
easier
to
feed
them
through
the
gland.
5
Connect
Ethernet
cables
as
follows:
•
APs,
BH10s,
or
BH20s
(PTP
100
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
Motorola
600S
SD
surge
suppressor
(model
number
600S
SC
or
later)
should
be
mounted
outside
the
building
or
communications
hut
on
each
line
at
the
point
of
cable
penetration
to
prevent
overvoltages
and
over-currents
from
entering
the
building
and
potentially
damaging
other
electronic
equipment.
•
T
errestrial
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
Motorola
600S
SD
surge
suppressor
(model
number
600S
SC
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.
•
T
errestrial
feeds
over
100
Mbps
(1000BaseT
Gigabit
Ethernet)
:
cable
directly
to
the
Gigabit
port
of
the
EtherWAN
switch,
and
mount
a
Motorola
PTP
-LP
U
lightning
protection
unit
or
equivalent
within
3
ft
(1 m)
of
the
CMM4
if
the
CMM4
is
located
outdoors
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
(P
owered
InDoor
Unit)
also
inside
the
building,
and
install
a
Hyperlink
T
echnologies
AL-CA
T6HP
-JW
surge
suppressor
(only
needed
in
special
cases)
or
equivalent
on
the
outside
of
the
building
or
communications
hut
at
the
point
of
cable
penetration.
