CHAPTER 7: CONFIGURATIONS 95
Non-Standard Tier Configuration
Guidelines for Existing Firmware Versions
Non-Standard tier configurations are those configurations supported by Paragon II, but require
special procedures in order to function properly. These include:
• Triangle Configuration
• Single Diamond Configuration
• Redundant Configuration
Recovery:
− After any re-connection subsequent to the Non-Standard tier configuration, all UMTs
should undergo a FUNC reset to clear the database. See Reset Unit under Paragon II
Front Panel Display and Controls in Chapter 2 for more information on clearing the
database. This procedure should be performed starting from the third-tier device down to
the Base Unit.
− Whenever a third-tier UMT is replaced, all of the second-tier and base UMTs should
undergo a FUNC reset.
− Whenever a second-tier UMT is replaced, all of the base UMTs should undergo a FUNC
reset.
− Whenever a base UMT is replaced, only the new UMT should undergo a FUNC reset.
−
Triangle Configuration
The following procedure must be followed to ensure this configuration functions properly:
After re-connection, all UMTs must undergo a FUNC reset to clear the switch database. See
Reset Unit under Paragon II Front Panel Display and Controls in Chapter 2 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-2A → UMT-Base 1.
