The aim of the Main Units (such as P2-UMT1664“M”) and Stacking Units
(such as P2-UMT1664“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 the HIGHEST tiered
device and end with the Base Unit (first-tier Paragon switch). For example,
in a “Single Base” configuration (only one Paragon 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
