In order to make a redundant configuration system operate more efficiently, the following
connection scheme between tiers is recommended:
connection scheme between tiers is recommended:
− Assume there are two UMT Base devices, the UMT-Base 1 and UMT-Base 2
− Assume there are three UMT second tier devices, the UMT-2A, UMT-2B, and UMT-2C
− Channel connection of UMT-Base 1
− Assume there are three UMT second tier devices, the UMT-2A, UMT-2B, and UMT-2C
− Channel connection of UMT-Base 1
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-Base 2
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.
configurations described in this chapter.
Loop-Back Configuration
This dead-loop setup will cause Server database conflict and should therefore never be used.
