Introduction 1 - 5
Complete ONline Control
When you install an EMM into a concentrator for the first time and it
becomes master, it automatically learns and saves the configurations of all
existing modules and their ports. The EMM provides the following features
that maximize security and minimize the risk of losing module and port
configuration settings:
All known modules installed in an ONline System Concentrator after
an EMM has been installed will have all ports disabled to prevent
unapproved connections and will be set to the network setting of
isolated. The one exception is when a module is unknown to the
EMM, in which case it will be configured off its dip switch settings.
If you remove any module from the concentrator and then reinstall it,
or another module of the same type in the original slot, the EMM will
automatically configure it as it was as of the last save.
If you replace an EMM with another EMM, the new EMM
automatically learns the module and port configurations. However,
you will need to configure the new EMM to the proper terminal and
device settings.
