Troubleshooting
This
chapter
provides
information
concerning
the
following:
Unless
otherwise
noted,
the
following
information
applies
to
all
DFE
modules.
Using LANVIEW
The
modules
use
a
built
‐
in
visual
diagnostic
and
status
monitoring
system
called
LANVIEW.
The
LANVIEW
LEDs
(
Figure 4
‐
1
)
allow
quick
observation
of
the
network
status
to
aid
in
diagnosing
network
problems.
About the Management (MGMT) LED
The
MGMT
LED
(shown
in
Figure 4
‐
1
)
indicates
when
the
module
is
serving
as
the
Management
Module
to
control
the
management
functions
for
all
DFE
modules
in
the
chassis.
The
Management
Module
handles
all
IP
requests
to
the
chassis
IP
address,
such
as
PING,
Telnet,
SNMP,
and
HTTP.
The
Management
Module
also
handles
the
CLI
configuration
sessions
by
means
of
the
console
port.
So,
when
you
plug
into
a
DFE
module
COM
port
to
configure
a
module
in
the
chassis,
it
is
handled
by
the
Management
Module
regardless
of
the
DFE
module
COM
port
that
you
use.
Viewing the Receive and Transmit Activity
On
the
7G4202
‐
72
and
7G4282
‐
49,
you
can
view
the
receive
and
transmit
activity
on
the
RX
and
TX
LEDs.
However,
only
one
group
of
ports
may
be
viewed
at
a
time.
On
the
7G4282
‐
49,
there
are
8
ports
per
group.
On
the
7G4202
‐
72,
there
are
20
ports
per
group.
To
view
the
receive
and
transmit
activity
on
a
group
of
attached
segments,
press
the
GROUP
SELECT
button
(see
Figure 4
‐
1
)
to
step
to
the
group
of
interest
(Groups
1
‐
3
for
the
7G4202
‐
72,
and
Groups
1–5
for
the
7G4282
‐
49).
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.
