Introduction:
Tech doc to advise that device connected via a fanout model are not suppressed because fanouts do not have the full fault isolation capability.
 
Question:
When upstream device is down why are all models connected via fanout not suppressed when all others are suppressed
 
Answer:
Fanouts do not have the fault isolation capability that enables the fault isolation process to determine that the upstream device is the problem.
 
We would recommend to use in place of a fanout a SharedMediaLink model which has enhanced fault isolation capabilities.
