Unit Numbering within the Fabric 79
■ Fabric topology is ‘discovered’ and the units auto-number their IDs.
Adding and removing units from the Fabric does not cause any
renumbering to occur and the Fabric will continue to work normally.
Renumbering only occurs when the Fabric is next power cycled if the
units are configured to auto-number.
The unit LEDs will display the unit number in the Fabric, from 1 to 8.
