Important
The following procedures assume that all switches have a clean configuration from manufacturing.
When adding a new switch to an already running stack, it is also assumed that the new switch is
using the same firmware image version as other switches in the stack.
Note: Once switch IDs are assigned, they are persistent and will be retained during a
power cycle to any or all of the switches.
