Figure 21: FI down cable configuration
Note:
Avaya recommends you to use the FI down configuration. Many network management
software packages assume a down configuration.
FI up configuration
In a FI up 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
bottom unit in the Stack. This bottom unit is designated unit 2. The Stack is wired upwards
though the units and the software continues to number up though the Stack. In this
configuration, the Base unit discovers the Stack in a FI up direction. The following illustration
shows a typical FI up configuration.
