Overview of DFE Module Shutdown Procedure

The DFE modules installed in a Matrix E7,Matrix N1, 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" on page 4‐6)
• Last resort shutdown procedure (not recommended) ("Last Resort Shutdown Procedure" on
page 4‐7)
Possible Cause
Position of Mode switch (7),
Persistent Data Reset, was
changed sometime before
either cycling power or
pressing the RESET button,
causing the user-entered
parameters to reset to factory
default settings.
Clear Persistent Data that
was set through Local
Management.
The module was moved
either from slot-to-slot or from
chassis-to-chassis.
Caution: Do not remove a DFE-Diamond module from an operating chassis system before reading
the following information and instructions.
Precaución: Antes de retirar los módulos DFE-Diamond del chasis en funcionamiento, lea las
