PowerConnect 7000 Series and M6348 Stacking Compatibility The stack can contain any combination of switch models in the PowerConnect 7000 Series as well as the PowerConnect M6348 switch, as long as all switches are running the same firmware version. For example, a single stack of six switches might include the following members: • Two PC7048 switches • One PC7024 switch • Three PCM6348 switches Any member can be the stack Management Unit. How is the Management Unit Selected? A stack manager is elected or re-elected based on the following considerations, in order: 1 The switch is currently the stack manager. 2 The switch has the higher MAC address. NOTE: The terms "Master" and "Manager/Management Unit" are often used interchangeably through out this chapter. In most cases, a switch that is added to an existing stack will become a stack member, and not the Management Unit. 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 Management Unit function enabled but another Master unit is already active, then the switch changes its configured Management Unit value to disabled. • If the Management Unit function is unassigned and there is another Management Unit in the system then the switch changes its configured Management Unit value to disabled. • If the Management Unit function is enabled or unassigned and there is no other Management Unit in the system, then the switch becomes Management Unit.
