Property Description
• 16 = Blade
• 17 = Blade Expansion
NOTE: This enumeration expands on the list in the Entity
MIB (the attribute, entPhysicalClass). The numeric values
are consistent with CIM's enum numbering guidelines, but
are slightly dierent than the MIB's values.
The values Rack through Port/Connector are dened per the
Entity-MIB (where the semantics of rack are equivalent to the
MIB's stack value).
The other values (for battery, processor, memory, power source/
generator and storage media package) are self-explanatory. A value
of Blade should be used when the PhysicalPackage contains the
operational hardware aspects of a ComputerSystem, without the
supporting mechanicals such as power and cooling. For example, a
Blade Server includes processor(s) and memory, and relies on the
containing chassis to supply power and cooling.
In many respects, a Blade can be considered a Module/Card.
However, it is tracked dierently by inventory systems and diers in
terms of service philosophy. For example, a Blade is intended to be
hot-plugged into a hosting enclosure without requiring additional
cabling, and does not require a cover to be removed from the
enclosure for installation. Similarly, a Blade Expansion has
characteristics of a Blade and a Module/Card. However, it is
distinct from both due to inventory tracking and service philosophy,
and because of its hardware dependence on a Blade. A Blade
Expansion must be attached to a Blade prior to inserting the
resultant assembly into an enclosure.
PartNumber
The part number assigned by the organization that is responsible for
producing or manufacturing the PhysicalElement.
PropertyOwnershipTag
Property Ownership Tag of a system.
SecurityBreach
An enumerated, integer-valued property indicating whether a
physical breach of the Frame was attempted but unsuccessful
(value = 4) or attempted and successful (value = 5).
Possible values are:
• 1 = Other
• 2 = Unknown
• 3 = No Breach
• 4 = Breach Attempted
• 5 = Breach Successful
SKU
The stock-keeping unit number for this PhysicalElement.
Tag
An arbitrary string that uniquely identies the Physical Element and
serves as the key of the Element. The Tag property can contain
information such as asset tag or serial number data. The key for
PhysicalElement is placed very high in the object hierarchy in order
to independently identify the hardware or entity, regardless of
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 can even be inserted into a
dierent scoping container. Therefore, the key for Physical Element
