DGS-3100 Series Gigabit Stackable Managed Switch User Manual • A running stacking member group is added to an existing stack, assuming each one of the stack groups has an elected Stack Master. The total of existing stacking members and new stacking members exceeds the maximum allowed number of stacking members in a stack, which is 6 stacking members: - Master Detection and Master Election processes determine the master out of one of two combined stacking groups. - When switches are added to a running stack, the Unit ID Allocation and Duplicate ID Conflict Resolution process detects an error if too many switches are present in the stack, and no changes are to stacking members that originally belonged to the group managed by the newly elected master. The original switches retain their ID assignments and configurations. The stacking members that originally belonged to the group managed by the Stack Master that lost the Master Election process are shut down. 25
