OVERVIEW OF DFE MODULE SHUTDOWN PROCEDURE
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.
The DFE modules installed in a Matrix E7, Matrix N3, 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 button
shown in
Figure
4-2. There are two procedures to shut down a DFE module.
•
