The
Ethernet
RF
Modem
does
not
sup
‐
port
Power
‐
over
‐
Ethernet
(PoE).
The
device
cannot
be
powered
directly
from
a
PoE
port
on
a
compatible
hub.
However,
it
may
be
useful
to
send
power
on
the
unused
wires
of
the
CAT
‐
5
cable
in
a
situation
where
the
radio
will
be
mounted
in
a
location
that
optimizes
radio
coverage,
but
may
not
have
a
power
outlet
nearby.
There
are
several
third
party
devices
available
that
can
inject
the
power
onto
the
cable
and
then
remove
it
at
the
remote
side.
