FI down configuration
In a FI down configuration, the base unit is physically located at the top of the stack. The
software automatically numbers the physical units based on the designated base unit (unit 1).
The FI cables connected to the FI-down ports of the base unit terminates in the FI-up ports on
the next unit in the stack, located below the base unit. The next unit is designated unit 2. The
FI stack is wired downward though the units and the software continues to number down
through the FI stack. In this configuration, the base unit discovers the virtual fabric in a FI down
direction. The following illustration shows a typical FI down configuration.

Note:
Avaya recommends you to use the FI down configuration. Many network management
software packages assume a stack down configuration.
