Overview of DFE Module Shutdown Procedure
The
DFE
modules
installed
in
a
Matrix E7,
Matrix
N3,
Matrix
N5,
or
Matrix
N7
chassis
are
interdependent
and
operate
under
a
single
IP
address
as
a
single,
distributed
switch
system
(hardware,
databases,
and
persistent
storage).
In
this
operating
environment,
the
DFE
module
must
shut
down
in
an
orderly
fashion
to
ensure
that
the
other
modules
in
the
system
and
other
devices
on
the
network
are
notified
of
the
impending
change.
The
device(s)
can
then
make
intelligent
decisions
and
stabilize
the
network
before
the
change
is
made,
thereby
increasing
network
availability.
You
can
shut
down
a
DFE
module
in
an
operating
system
using
the
OFFLINE/RESET
switch
shown
in
Figure 4
‐

.
There
are
two
procedures
to
shut
down
a
DFE
module.

User parameters (IP
address, device and
module name, etc.)
were lost when the
module power was
cycled, the front
panel OFFLINE/
RESET switch was
pressed.
Position of Mode switch (7),
Persistent Data Reset, was
changed sometime before
either cycling power or
pressing the OFFLINE/RESET
switch, causing the user-
entered parameters to reset to
factory default settings.
Clear Persistent Data that was
set through Local
Management.
The DFE module was moved
either from slot-to-slot or from
chassis-to-chassis.
Reenter the lost parameters as
necessary. Refer to the
Enterasys Matrix
DFE-Platinum Series Configuration Guide
for the instructions to configure the
DFE module.
If the problem continues, contact
Enterasys Networks for technical support.
