This reports the connectivity status of this slot's redundant path (whether the physical wiring path to the chassis I/O modules is intact). For this chassis slot's endpoint for whatever blade currently occupies it, connPath specifically covers the cabling/backplane path rather than the logical link state, so it's the field to check when a blade lost redundancy because one physical path failed even though the blade itself is still reachable through the other. A value of 'A' or 'A,B' here tells an admin whether this slot currently has one or both redundant fabric paths physically connected.
