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, 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 4‐3. There are two procedures to shut down a DFE module.

•Recommended shutdown procedure (“Recommended Shutdown Procedure Using OFFLINE/RESET Switch” on page 4‐11)

•Last resort shutdown procedure (not recommended) (“Last Resort Shutdown Procedure Using OFFLINE/RESET Switch” on page 4‐12)
