Property Description
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.
Serial Number
Manufacturer-allocated number is used to identify the physical
element.
Version
Indicates the version of the identified physical element.
Tag
An arbitrary string that uniquely identifies 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 different
scoping container. Therefore, the key for Physical Element is
an arbitrary string and is defined independently of any
placement or location-oriented hierarchy.
VendorCompatibilityStrings
An array of strings that identify the component that is
compatible with, and can be inserted in a slot that reports this
string as one of the array element in the
VendorCompatibilityStrings. This allows system administrators
to determine whether it is appropriate to insert a package into
a slot to ensure uniqueness within the NameSpace, each value
defined by the vendor for use in the
VendorCompatibilityStrings property SHOULD be constructed
using the following preferred algorithm: : Where and are
separated by a colon ':', and where MUST include a
copyrighted, trademarked or otherwise unique name that is
owned by the business entity creating/defining the
InstanceID, or is a registered ID that is assigned to the
