Overview of DFE-Diamond Module Shutdown Procedure
The DFE ‐ Diamond 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 ‐ Diamond
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 ‐ Diamond module in an operating system using the OFFLINE/RESET
switch shown in Figure 4 ‐ 2 . There are two shut down procedures.
• Recommended shutdown procedure (“ Recommended Shutdown Procedure Using OFFLINE/
RESET Switch ” on page 4 ‐ 6)
• Last resort shutdown procedure (not recommended) (“ Last Resort Shutdown Procedure
Using OFFLINE/RESET Switch ” on page 4 ‐ 7)
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
Enterasys Matrix DFE-Diamond/Platinum Series
Configuration Guide for the instructions to configure
the device.
If the problem continues, contact Enterasys Networks
for technical support.
