Description: This table lists the orderable part number, serial number, hardware revision, manufacturing assembly number and revision, firmwareID and revision if any, and softwareID and revision if any, of relevant entities listed in the ENTITY-MIB entPhysicalTable.

Entities for which none of this data is available are not listed in this table. This is a sparse table so some of these variables may not exist for a particular entity at a particular time. For example, a powered-off module does not have softwareID and revision; a power-supply would probably never have firmware or software information.

Although the data may have other items encoded in it (for example manufacturing-date in the serial number) please treat all data items as monolithic. Do not decompose them or parse them. Use only string equals and unequals operations on them.
