Troubleshooting
Viewing the Receive and Transmit Activity
On
the
4G4202
‐
60
and
4G4282
‐
41,
you
can
view
the
receive
and
transmit
activity
on
the
RX
and
TX
LEDs.
However,
only
one
group
of
20
ports
may
be
viewed
at
a
time.
To
view
the
receive
and
transmit
activity
on
a
group
of
attached
segments,
press
the
GROUP
SELECT
button
(see
Figure 4
‐

)
to
step
to
the
group
of
interest
(Groups
1
‐
3
for
the
4G4202
‐
60,
and
Groups
1
‐
5
for
the
4G4282
‐
41).
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
port.
