Matrix DFE-Platinum Series Installation Guide 3-7
Figure 3
‐
3
shows
connecting
a
twisted
pair
segment
to
the
2G4082
‐
25
module.
It
is
assumed
that
the
chassis
power
is
turned
on
to
provide
power
to
the
module.
Refer
to
Figure 3
‐
3
and
proceed
as
follows:
1.
Ensure
that
the
device
connected
to
the
other
end
of
the
segment
is
powered
ON.
2.
Connect
the
twisted
pair
segment
to
the
module
by
inserting
the
RJ45
connector
on
the
twisted
pair
segment
into
the
appropriate
RJ45
port
connector.

Verify
that
a
link
exists
by
checking
that
the
port
RX
(Receive)
LED
is
ON
(flashing
amber,
blinking
green,
or
solid
green).
If
the
RX
LED
is
OFF
and
the
TX
(Transmit)
LED
is
not
blinking
amber,
perform
the
following
steps
until
it
is
on:
a.
To
view
the
receive
and
transmit
activity
on
a
group
of
segments,
press
the
GROUP
SELECT
button
(see
Figure 3
‐
3
)
to
step
to
the
group
of
interest
(Groups
1
and
2).
Each
time
the
GROUP
SELECT
button
is
pressed,
the
GROUP
LED
lights
up
in
sequence,
indicating
which
Group
is
selected.
The
receive
and
transmit
activity
for
that
group
of
segments
is
then
indicated
by
the
RX
and
TX
LEDs
for
each
segment.
b. Verify
that
the
cabling
being
used
is
Category
5
UTP
with
an
impedance
between
85
and
111 ohms.
For
the
port
to
operate
at
100
or
1000
Mbps,
Category 5
cabling
must
be
used
and
installed
properly.
c.
Verify
that
the
device
at
the
other
end
of
the
twisted
pair
segment
is
on
and
properly
connected
to
the
segment.
d. Verify
that
the
RJ45
connectors
on
the
twisted
pair
segment
have
the
proper
pinouts
and
check
the
cable
for
continuity.
Typically,
a
crossover
cable
is
used
between
hub
devices.
A
straight
‐
through
cable
is
used
to
connect
between
switches
or
hub
devices
and
an
end
user
(computer).
Refer
to
Figure 3
‐

and
Figure 3
‐

for
four
‐
wire
RJ45
connections.
Refer
to
Figure 3
‐
6
and
Figure 3
‐
7
for
eight
‐
wire
RJ45
connections.
