CHAPTER 7: CONFIGURATIONS 61
Redundant Configuration
The procedure outlined below must be followed to ensure this configuration functions properly:
− After installation, all UMT Matrix Switches should undergo a FUNC reset to clear the switch
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-Base 1 → UMT-Base 2.
− Whenever a third tier UMT Matrix Switch is replaced, all of the second tier and base UMT Matrix
Switches should undergo a FUNC reset.
− Whenever a second tier UMT Matrix Switch is replaced, all of the base UMT Matrix Switches
should undergo a FUNC reset.
− Whenever a base UMT Matrix Switch is replaced, only the new UMT Matrix Switch should
undergo a FUNC reset.
