What is entPhysicalIsFRU?

A true/false flag indicating whether this physical component is a field-replaceable unit according to the vendor; components permanently built into a FRU report false. An admin uses this to distinguish swappable parts, like a power supply, from fixed sub-components that can't be individually replaced.
