physical element is

SerialNumber A manufacturer-
allocated number used
to identify the physical
element.
string
Tag Uniquely identifies the
physical element and
serves as the element’s
key. The Tag property
can contain information
such as asset tag or
serial number data. The
key for a physical
element is placed very
high in the object
hierarchy in order to
identify the hardware/
entity independently,
regardless of the
physical placement in or
on cabinets, adapters,
and so on. For example,
a hotswappable or
removable component
can be taken from its
containing (scoping)
package and be
temporarily unused. The
object still continues to
exist and may even be
inserted into a different
scoping container.
Therefore, the key for
the physical element is
an arbitrary string that is
defined independently
of any placement or
location-oriented
hierarchy.
