CLX node loss fault

I have a CLX system with multiple nodes on ethernet. If communcations to one or more nodes is lost then the plc faults and shuts doen the entire plant. Is this a configuration error or is there a way to mask out the faults so that the system doesn't shut down? Thanks for any suggestions.

Tha fisrt question is what kind of ethernet switch are you using ??
What about UTP cables and optical fiber integrity ??

If you open each node in Logix5000 and look at the connection tab there should be a checkbox for "Major Fault On Controller if Connection Fails While in Run Mode". Uncheck this to stop a node loss from faulting the processor.
