Dfe-Gold Module Shutdown Procedure - Enterasys Gold Distributed Forwarding Engine 4G4282-49 Hardware Installation Manual

DFE-Gold Module Shutdown Procedure

Table 4-2 Troubleshooting Checklist (continued)
Problem
Port(s) goes into
standby for no
apparent reason.
User parameters
(IP address, device
and module name,
etc.) were lost
when the module
power was cycled,
the front panel
OFFLINE/RESET
switch was
pressed.
DFE-Gold Module Shutdown Procedure
The DFE‐Gold 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‐Gold 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 that ensure the
stability of 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
cycling power or
pressing the OFFLINE/
RESET switch, 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 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.
Recommended Action
Verify that Spanning Tree is enabled. Refer to the
