2 The switch has the higher MAC address. 3 A unit is selected as standby by the administrator, and a fail over action is manually initiated or occurs due to stack master failure. In most cases, a switch that is added to an existing stack will become a stack member, and not the stack master. When you add a switch to the stack, one of the following scenarios takes place regarding the management status of the new switch: • If the switch has the stack master function enabled but another stack master is already active, then the switch changes its configured stack master value to disabled. • If the stack master function is unassigned and there is another stack master in the system then the switch changes its configured stack master value to disabled. • If the stack master function is enabled or unassigned and there is no other stack master in the system, then the switch becomes stack master. • If the stack master function is disabled, the unit remains a non-stack master. If the entire stack is powered OFF and ON again, the unit that was the stack master before the reboot will remain the stack master after the stack resumes operation. You can manually set the unit number for the switch. To avoid unit-number conflicts, one of the following scenarios takes place when you add a new member to the stack: • If the switch has a unit number that is already in use, then the unit that you add to the stack changes its configured unit number to the lowest unassigned unit number. • If the switch you add does not have an assigned unit number, then the switch sets its configured unit number to the lowest unassigned unit number. • If the unit number is configured and there are no other devices using the unit number, then the switch starts using the configured unit number. • If the switch detects that the maximum number of units already exist in the stack making it unable to assign a unit number, then the switch sets its unit number to unassigned and does not participate in the stack.
