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.
