           This MIB is used to report AC power attributes in devices.
           The table is a sparse augmentation of the eoPowerTable table
           from the energyObjectMib module.  Both three-phase and
           single-phase power configurations are supported.

           As a requirement for this MIB module, RFC 7461 SHOULD be
           implemented.

           Module Compliance of ENTITY-MIB v4 with respect to
           entity4CRCompliance MUST be supported which requires
           implementation of four MIB objects: entPhysicalIndex,
           entPhysicalClass, entPhysicalName, and entPhysicalUUID."
