Chapter 10: Configurations

Redundant Configuration
These configurations are simply more complex configurations, and might
be used to ensure redundancy; every Base Unit is configured to another,
in case of individual system failure.
The following procedure must be followed to ensure this configuration
functions properly.
After re-connection, all Paragon switches must undergo a FUNC
reset to clear the switches' database. See Reset Unit (on page
44) for more information on clearing the database. This
pro
c
edure should be performed starting from the third-tier device
down to the Base Unit.
Execute the FUNC reset in the following order: UMT-3A -->
UMT-3B --> UMT-2A --> UMT-2B --> UMT-1A --> UMT-1B.
Whenever a third-tier Paragon switch is replaced, all of the
second-tier Paragon switches and Base Units should undergo a
FUNC reset.
Whenever a second-tier Paragon switch is replaced, all of the
Base Units should undergo a FUNC reset.
Whenever a base-tier Paragon switch (Base Unit) is replaced,
only the new Paragon switch should undergo a FUNC reset.
