Port pruning

l

When power budget is exceeded, ports will be pruned based on their priority (first low priority

ports, then high priority ports and finally, critical priority ports).

l

If the decision has to be made between ports with equal priority, the biggest port number will be

pruned.

l

If a higher priority device gets connected and there is no power budget for it, then the lowest

priority port will get pruned based on the logic presented above.
