The vendor-specific serial number string for the physical
entity. The preferred value is the serial number string actually
printed on the component itself (if present).
On the first instantiation of a physical entity, the value of
entPhysicalSerialNum associated with that entity is set to the
correct vendor-assigned serial number, if this information is
available to the agent. If a serial number is unknown or
non-existent, the entPhysicalSerialNum will be set to a
zero-length string instead.
Note that implementations that can correctly identify the
serial numbers of all installed physical entities do not need to
provide write access to the entPhysicalSerialNum object.
Agents that cannot provide non-volatile storage for the
entPhysicalSerialNum strings are not required to implement
write access for this object.
Not every physical component will have a serial number, or
even need one. Physical entities for which the associated
value of the entPhysicalIsFRU object is equal to "false(2)"
(for example, the repeater ports within a repeater module), do
not need their own unique serial number. An agent does not
have to provide write access for such entities, and may return
a zero-length string.
If write access is implemented for an instance of
entPhysicalSerialNum, and a value is written into the
instance, the agent must retain the supplied value in the
entPhysicalSerialNum instance associated with the same
physical entity for as long as that entity remains instantiated.
This includes instantiations across all re-initializations/
reboots of the network management system, including those
that result in a change of the physical entity's
entPhysicalIndex value.
