Table 4-3 Troubleshooting Checklist (Continued)
Problem
Port(s) goes into
standby for no
apparent reason.

power was cycled,
the front panel
OFFLINE/RESET
switch was

Overview of DFE-Platinum Module Shutdown Procedure
DFE modules installed in an SS6000, Matrix N3, Matrix N7, or Matrix E7 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.
4-6 Troubleshooting
Possible Cause
Loop condition
detected.
Position of Mode switch
(7), Persistent Data
Reset, was changed
sometime before either

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-Platinum 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
