This is the process to remove a unit from the stack.
Steps
1. User can manually disconnect the unit by removing stacking cables. Unit can be disconnected while
it's powered on or off.
2. When unit is disconnected, it will have stacking enabled. To recover to a clean unit user can use
'stack unconfigure clean' or 'stack unconfigure me' commands on this unit.
3. If the removed unit was dynamically learned, the active unit will remove this unit from configuration.
If the removed unit was static, the configuration can be removed by issuing 'no stack unit <unit id>'
command.
4. To temporarily disable a unit from stack, on the active unit enter stack disable command for the
particular unit.
5. Please note that 'Stack unconfigure me' will recover the unit to its startup configuration before it
joined the stack. 'Stack unconfigure clean' will remove unit's startup configuration. These
commands will reload the unit and boot up as standalone unit.
Replacing a unit from the stack
Assumption
• All the units have sequential IDs
• Replacing with a clean unit
Description
If the user wants to replace an old unit from the stack, the two options are as follows:
1. Replacing an old stack unit with a clean stack unit
2. Replacing multiple stack units with multiple clean stack units
Steps
Replacing one stack unit with a clean stack unit
1. After removing the old unit from the stack, connect the new unit to the stack using the same
stacking ports used by the old unit.
2. If the module configuration of the replacement unit matches the configuration on the Active
Controller, the Active Controller resets the new unit and upon boot up new unit joins the stack with
the same ID was the unit that was removed, and the stack retains its original topology.
3. If the configuration of the new unit does not match the old unit, the new unit is added with a new ID
based on the next available ID.
Replacing multiple stack units with multiple clean stack units
1. After removing the old stack units, connect the new units to the existing stack using the stacking
ports as the old unit.
2. The active controller replaces the unit with the lowest ID first. For example, if you remove units 4
and 5, the active controller assigns ID 4 to the first new device you install.
3. If you wanted this particular unit to replace unit 5, instead of unit 4, you must use secure-setup to
select the ID of the old unit for the new unit. The active controller resets the unit, and upon boot up it
joins the stack.
