Problem
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.
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
• Recommended shutdown procedure ("Recommended Shutdown Procedure Using
OFFLINE/RESET Switch" on page 4‐11)
• Last resort shutdown procedure (not recommended)
Procedure Using OFFLINE/RESET Switch" on page 4‐12)
4-10 Troubleshooting
Possible Cause
Position of Mode switch (7),

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.
Caution: Do not remove a DFE module from an operating chassis system before reading
the following information and instructions.
Precaución: Antes de retirar los módulos DFE del chasis en funcionamiento, lea las
siguientes instrucciones y la información suministrada.
4‐3. There are two procedures to shut down a DFE module.
Recommended Action
