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 
procedure 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.
