Figure 26: StackPower Star Topology
StackPower Partitioning Examples
These figures show StackPower stacks of switches with failover conditions.
In the following figure, the StackPower cable 2 is faulty. This is considered a broken ring and is a fault
condition. Power is still shared across the stack, but this condition will place a limitation on power budgeting
and the number of high priority ports it can protect in the case of any further failures such as failure of power
supply, AC mains, StackPower port and so on. StackPower is not intended for secondary failures and hence
restoration of the failed component or power should be done immediately.
