Important
The following procedures assume that all units have a clean configuration from manufacturing. When adding
a new unit to an already running stack, it is also assumed that the new unit is using the same firmware image
version as other units in the stack.
Notes: Ensure that each switch is fully operational before applying power to the next switch.
Since unit IDs are assigned on a first-come, first-served basis, this will ensure that unit IDs are
ordered sequentially.
Once unit IDs are assigned, they are persistent and will be retained during a power cycle to any or
all of the units.
