Chapter 7: Configurations
When implementing complex tiered and stacked architectures for a Paragon system, there are important
guidelines describing the legal and illegal configurations among devices in a Paragon system, and the
procedures to make the system function in the appropriate manner that you must follow and procedures to
make the system function in an appropriate manner.
Principles of Re-Connection
Whenever a change is made to a connected tiered device, it is recommended that power to all devices
is recycled, if possible. This includes the device where the connection is changed directly, as well as all
devices below it in the system architecture.
The sequence of power recycling should start from highest tiered device and end with the Main base
unit. For example, in a “Single Base” configuration (only one UMT Matrix Switch as the base unit), if
a connection change is made at a device on the third tier, the sequence of power recycling should be as
follows:
The third tier device with the changed connection
The second tier device connected to the third tier device
The base unit
In the event that a change is required for an existing configuration, the chapter illustrates proper procedures
for adding or removing units and changing tier paths.
