5. iMcV module DIP Switch settings can be used to make initial configuration
settings overriding the management module’s setting. (See examples.)
INSERTING AN IMCV MODULE
1. Without Configuration Control
•
DIP Switches are ignored and the iMcV module takes the
configuration from the management module. This could be the default
configuration or from a previously installed module.
2. With Configuration Control
•
If the iMcV module is different (model or DIP Switch settings) from the
iMcV module installed in the slot previously, then the DIP Switch
settings are used for configuration. This configuration is then copied
up to the management module.
•
If the iMcV module is exactly the same (model and DIP Switch
settings) to the iMcV module previously installed, the iMcV module
will use the settings from the management module.
INSERTING A MANAGEMENT MODULE
•
Without Configuration Control
o
iMcV modules in an unmanaged chassis use DIP Switch settings.
When the management module is inserted, the iMcV modules
use the configuration stored in the management module. This will
more than likely change the configuration of the iMcV modules -
at the very least causing a short interruption in data flowing
through the iMcV modules.
•
With Configuration Control
o
The iMcV modules copy their configuration up to the
management module. The iMcV modules keep working with no
configuration change and no interruption in data.
NOTE
:
If the end user has a mixture of standard iMcV modules and 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.
** WARNING **
Installing modules without understanding the effects of LinkLoss and FiberAlert can cause
functioning units to appear flawed or even non-functional.
