Chapter 7: Configurations
The aim of the Main Switching Units (UMT “M”) and Stacking Units (UMT “S”) is to allow
users to build the Paragon system to include additional channel ports and the tiers up to three
levels, so that more users and channels can be configured to control more servers. The system
does not need to be over-redundant in accessibility, but administrators should consider the
configurations illustrated in this chapter. In more complex stacked Paragon setups, there are
important guidelines about legal and illegal device configurations that must be followed to ensure
functionality.
Principles of Re-Connection
When a change is made to a connected tiered device, we 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
Master Base Unit. For example, in a “Single Base” configuration (only one UMT 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 (first tier)
