'The ExternalReferenceDesignator property indicates the external reference designator of the port. External reference designators are identifiers that determine the type and use of the port. Example: COM1'
ExternalReferenceDesignator property is in 1 class (Win32_PortConnector) of ROOT\CIMV2\ms_409 and in 2 namespaces
'The InternalReferenceDesignator property indicates the internal reference designator of the port. Internal reference designators are specific to the manufacturer and identify the circuit board location or use of the port. Example: J101'
InternalReferenceDesignator property is in 1 class (Win32_PortConnector) of ROOT\CIMV2\ms_409 and in 2 namespaces
'CreationClassName indicates the name of the class or the subclass used in the creation of an instance. When used with the other key properties of this class, this property allows all instances of this class and its subclasses to be uniquely identified.'
'The InstallDate property is datetime value indicating when the object was installed. A lack of a value does not indicate that the object is not installed.'
'The name of the organization responsible for producing the physical element. This may be the entity from whom the element is purchased, but this is not necessarily true. The latter information is contained in the Vendor property of CIM_Product.'
'OtherIdentifyingInfo captures additional data, beyond asset tag information, that could be used to identify a physical element. One example is bar code data associated with an element that also has an asset tag. Note that if only bar code data is available and is unique/able to be used as an element key, this property would be NULL and the bar code data used as the class key, in the tag property.'
'The Status property is a string indicating the current status of the object. Various operational and non-operational statuses can be defined. Operational statuses are "OK", "Degraded" and "Pred Fail". "Pred Fail" indicates that an element may be functioning properly but predicting a failure in the near future. An example is a SMART-enabled hard drive. Non-operational statuses can also be specified. These are "Error", "Starting", "Stopping" and "Service". The latter, "Service", could apply during mirror-resilvering of a disk, reload of a user permissions list, or other administrative work. Not all such work is on-line, yet the managed element is neither "OK" nor in one of the other states.'
