What is rlPhdUnitGenParamHardwareVersion?

This object's description text is also copied as 'Serial number of the product' in the source MIB, but per its name it reports the unit's hardware revision level. An admin needs the hardware version, distinct from software or firmware, to determine whether a given physical unit supports a particular feature or software release that has a minimum hardware-revision requirement. For example, before applying a new software image with a documented minimum hardware revision, the admin checks this field to confirm the unit's hardware version meets that requirement.
