SNMP Management Module, the High Density L2 Module with
Configuration Control will function based on its DIP Switch settings. If
the DIP Switches have not been changed, the stored configuration will
be used. The stored configuration can be extracted from the SNMP
Management Module or the DIP Switches.
• Replacing the same type of a High Density L2 Module with Configuration
Control
- If the DIP Switch settings are the same as the settings on the removed
High Density L2 Module, the new High Density L2 Modules with
Configuration Control 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 a High Density L2 Module with Configuration
Control
- 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 SNMP Manageable 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 High Density L2 Module or
High Density L2 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 High Density L2 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, while those without Configuration
Control will be set to their default settings.
4.2 Unmanaged Modules
Before installing, configure the L2 modules for desired features. The table on
the next page indicates the available features and settings for the L2 modules.
After configuring the DIP Switches for the desired settings, install the module
and connect the appropriate cables (refer to the Installating a High-Density
Media Converter System II Layer 2 section for more information).
