Stacking Dell PowerConnect 7000 Series Switches
Merging Two Operational Stacks
The recommended procedure for merging two operational stacks is as follows:
1. Always power off all units in one stack before connecting to another stack.
2. Add the units as a group by unplugging one stacking cable in the operational stack and
physically connecting all unpowered units.
3. Completely cable the stacking connections, making sure the redundant link is also in place.
Two operational stacks can also be merged by reconnecting stack cables without powering down units
in either stack. Connecting a powered-up standalone unit to an existing stack leads to same behavior as
when merging two operational stacks. In such cases, Manager election is performed and the Manager
unit with the higher MAC address wins the election. The losing stack manager resets itself and all of its
member units. After the reset, all the losing stack members join the winning stack to form a single
stack. The winning stack remains functional through the merge process.
