DFE-Gold Module Shutdown Procedure
4-6 Troubleshooting
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.
Port(s) goes into
standby for no
apparent reason. Loop condition
detected. Verify that Spanning Tree is enabled. Refer to the
Matrix DFE-Gold Series Configuration Guide for
the instructions to set the type of STA.
Review the network design resolve loops.
If the problem continues, contact
Enterasys Networks for technical support.
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. 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. Reenter the lost parameters as necessary. Refer
to the Matrix DFE-Gold Series Configuration
Guide for the instructions to configure the device.
If the problem continues, contact
Enterasys Networks for technical support.
