configuration on the unit will be used. The stored configuration can be
retrieved from the SNMP Management Module or the DIP Switches.

• Replacing the same type of iMcV-Module

If the DIP Switch settings are the same as the settings on the removed IE-
iMcV-T1-Mux/4 + Ethernet, the new IE-iMcV-T1-Mux/4 + Ethernet gets its
configuration settings from the SNMP Management Module.

If the DIP Switch settings are different, then the configuration of the module
is determined by the DIP Switch settings. (The settings are forwarded to the
SNMP Management Module and the values are saved.)

• Installing a different model of an iMcV-Module

If another type of module is installed into the same slot in a chassis, the
SNMP Management Module clears the memory of the previous
configuration for that slot; the installed iMcV-Module configures itself and
its configuration is forwarded to the SNMP Management Module, where the
values are saved.

The SNMP Write Lock switch does not impact any iMcV-Module or IE-iMcV-Module
with Configuration Control. Removing and installing a new SNMP Management
Module will no longer impact these modules, either. However, if there is a mixture of
iMcV-Modules with and without Configuration Control, the Write Lock Switch and a
new SNMP Management Module must be taken into consideration.

If the command cleandb is applied to an SNMP Management Module, all the settings
for the modules will be removed, but the Configuration Control modules will still be
based on the last change made. Those without Configuration Control will be set to
their default settings.

NOTE

If the end user has a mixture of standard iMcV-Modules as well as Configuration Control
iMcV-Modules, it is important to understand how SNMP and DIP Switches will impact the
cards depending on their capability. Standard iMcV-Modules cannot be upgraded to
Configuration Control capability, so it is strongly recommended to set the DIP Switches on
the modules and then configure them via software to match the same settings.
