 When non-Configuration Control iMcV-modules are placed in a
managed chassis, the iMcV-module’s DIP Switches are ignored and
the iMcV-module is configured by the chassis’ Management
Module. If the SNMP Management Module is removed or fails,
then the iMcV-modules will revert back to the DIP Switch settings.
When an iMcV-module configuration changes from the
Management Module’s settings to DIP Switch settings, the traffic
across the iMcV-module will be interrupted for a very short period
of time.
 When introducing a Management Module to a chassis full of
working non-Configuration Control iMcV-modules, the iMcV-
modules will stop using the DIP Switch settings and start using the
Management module’s settings. When an iMcV-module changes
from DIP Switch settings to the Management module’s settings, the
traffic across the iMcV-modules will be interrupted for a very short
period of time
 When removing an existing iMcV-module and replacing it with a
different model iMcV-module, the configuration of the former
iMcV-module remains.
Unmanaged Modules
Before installing, configure the IE-iMcV-2xLIM, TX/SFP modules for desired
features. The table below indicates the available features and settings for the IE-
iMcV-2xLIM, TX/SFP modules.
After configuring the DIP Switches for the desired settings, install the module and
connect the appropriate cables (refer to Installing an IE-iMcV-2xLIM, TX/SFP
section for more information).
