In order to make a redundant configuration system operate more efficient, the following connection
scheme between tiers is recommended:
Assume there are two UMT Base devices, the UMT-Base1 and UMT-Base2
Assume there are three UMT second tier devices, the UMT-2A, UMT-2B, and UMT-2C
Channel connection of UMT-Base1
Channel ports 3*N+1 (1, 4, 7....) connect to UMT-2A user ports sequentially, starting from
user port 1
Channel ports 3*N+2 (2, 5, 8....) connect to UMT-2B user ports sequentially, starting from
user port 1
Channel ports 3*N (3, 6, 9....) connect to UMT-2C user ports sequentially, starting from user
port 1
Channel connection of UMT-Base2
Channel ports 3*N+1 (1, 4, 7....) connect to UMT-2A user port sequentially, starting from
user port 9 if UMT-2A has 16 user ports.
Channel ports 3*N+2 (2, 5, 8....) connect to UMT-2B user port sequentially, starting from
user port 9 if UMT-2A has 16 user ports.
Channel ports 3*N (3, 6, 9....) connect to UMT-2C user port sequentially, starting from user
port 9 if UMT-2A has 16 user ports.

Illegal Configuration

Illegal configurations are those that are not currently supported by Paragon. Please use one of the
configurations described in this chapter.

Loop-Back Configuration

This dead-loop setup will cause Server database conflict and should therefore never be used.
