fcm Instance Physical Index

1.3.6.1.2.1.10.56.1.1.1.4

If this management instance corresponds to a physical component (or to a hierarchy of physical components) identified by the Entity-MIB, then this object's value is the value of the entPhysicalIndex of that component (or of the component at the root of that hierarchy). If there is no correspondence to a physical component (or no component that has an entPhysicalIndex value), then the value of this object is zero.
