In rare cases an N-Ring can have a “Partial Fault”. An example of this is to have a break in just one fiber in a duplex channel fiber pair. The screenshot below shows N-Ring Manager Status when a ‘Higher’ N-Ring Port (A2 or E2) is not receiving self health frames all the way around the N-Ring, though the other (low A1/E1) N-Ring port is:

N-Ring Partial Fault (Error on high port)!!
