Stacking Dell PowerConnect 7000 Series Switches
Page 22
Scenario 3
The following example contains a similar condition with a Master unit failover and consequent stack
split with five units in the stack, as Figure 4 shows.
Figure 4. Stack Split with Manager Failure
In this example, there is no link back to Switch 5 from Switch 1. In this case, if the Manager of the
stack goes down (failed/rebooted), the stack is split into two different stacks with units 1 and 2 in one
stack and units 4 and 5 in another. With this condition, none of the stacks will have a working Master
within the stack, so both of the stacks will elect new masters for each stack through the process based
on which unit has the highest base MAC address.
