CHAPTER 6: CONFIGURATIONS 79

In order to make a redundant configuration system operate more efficiently, the following

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

 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.

Loop-Back Configuration

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