Manually Assigning a New Unit to an Existing Stack

To manually assign a new unit a position in an existing stack, use the following steps.

  1. On the stack, determine the next available stack-unit number, and the management priority of the management unit.
    EXEC Privilege mode
    show system brief or show system stack-unit
  2. On the new unit, number it the next available stack-unit number.
    EXEC Privilege mode
    stack-unit stack-unit-number renumber stack-unit-new-number
  3. (OPTIONAL) On the new unit, assign a management priority based on whether you want the new unit to be the stack manager.
    CONFIGURATION mode
    stack-unit stack-unit-number priority priority-number
  4. Connect the new unit to the stack using stacking cables.
