The part number assigned by the 
  organization that is responsible for producing or manufacturing the 
  PhysicalElement.

Qualifiers:
-------------
MaxLen=65
MappingStrings={MIB.IETF|Entity-MIB.entPhysicalModelName}


  

  





SerialNumber 
public string SerialNumber



  
General Information:
A manufacturer-allocated number used to 
  identify the Physical Element.

Product Specific 
  Usage:
"Serial Number" string in the SMBIOS Memory Device (type 17) 
  structure.

Manufacturer 
public string Manufacturer



  
General Information:
The name of the organization responsible 
  for producing the PhysicalElement. This organization might 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.

Product Specific Usage:
"Manufacturer" string in 
  the SMBIOS Memory Device (type 17) 
  structure.

Qualifiers:
-------------
MaxLen=65
MappingStrings={MIB.IETF|Entity-MIB.entPhysicalMfgName, 
  MIF.DMTF|FRU|003.4}


  

  





ElementName 
public string ElementName



  
General Information:


Product Specific 
  Usage:
'ElementName' is constant. In CIM_Chip instances its value is 
  set to 'Managed System Memory 
  Chip'.

-------------
Override=ElementName

CreationClassName Key 
public string CreationClassName



  
General Information:
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.

Product Specific 
  Usage:

Qualifiers:
-------------

MaxLen=65


  

  





Tag Key 
public string Tag



  
General Information:
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.

Product Specific 
  Usage:
"Physical Memory N" where N is replaced with the zero-based 
  ordinal value of the device among all physical memory devices in the SMBIOS 
  table.

-------------

OperationalStatus 
public uint16[] OperationalStatus



  
General Information:
Indicates the current statuses of the 
  element. Various operational statuses are defined. Many of the enumeration's 
  values are self-explanatory. However, a few are not and are described here in 
  more detail. 
"Stressed" indicates that the element is functioning, but 
  needs attention. Examples of "Stressed" states are overload, overheated, and 
  so on. 
"Predictive Failure" indicates that an element is functioning 
  nominally but predicting a failure in the near future. 
"In Service" 
  describes an element being configured, maintained, cleaned, or otherwise 
  administered. 
"No Contact" indicates that the monitoring system has 
  knowledge of this element, but has never been able to establish communications 
  with it. 
"Lost Communication" indicates that the ManagedSystem Element is 
  known to exist and has been contacted successfully in the past, but is 
  currently unreachable. 
"Stopped" and "Aborted" are similar, although the 
  former implies a clean and orderly stop, while the latter implies an abrupt 
  stop where the state and configuration of the element might need to be 
  updated. 
"Dormant" indicates that the element is inactive or quiesced. 
  
"Supporting Entity in Error" indicates that this element might be "OK" but 
  that another element, on which it is dependent, is in error. An example is a 
  network service or endpoint that cannot function due to lower-layer networking 
  problems. 
"Completed" indicates that the element has completed its 
  operation. This value should be combined with either OK, Error, or Degraded so 
  that a client can tell if the complete operation Completed with OK (passed), 
  Completed with Error (failed), or Completed with Degraded (the operation 
  finished, but it did not complete OK or did not report an error). 
"Power 
  Mode" indicates that the element has additional power model information 
  contained in the Associated PowerManagementService association. 
  
"Relocating" indicates the element is being 
  relocated.
OperationalStatus replaces the Status property on 
  ManagedSystemElement to provide a consistent approach to enumerations, to 
  address implementation needs for an array property, and to provide a migration 
  path from today's environment to the future. This change was not made earlier 
  because it required the deprecated qualifier. Due to the widespread use of the 
  existing Status property in management applications, it is strongly 
  recommended that providers or instrumentation provide both the Status and 
  OperationalStatus properties. Further, the first value of OperationalStatus 
  should contain the primary status for the element. When instrumented, Status 
  (because it is single-valued) should also provide the primary status of the 
  element.

Capacity 
public uint64 Capacity



  
General Information:
The total capacity of this PhysicalMemory, 
  in bytes.

Product Specific Usage:
The Capacity parameter is 
  calculated using the SMBIOS 2.7.1 Memory Device table (Type 17). 
Starting 
  in Intel AMT 8.0 and SMBIOS 2.7.1, this table includes the Extended Size field 
  which was created to accommodate device memories larger than 32,767 MB (32 GB 
  - 1 MB). This new field is not supported in SOAP. The maximum memory size 
  which can be reported by SOAP is 7FFFh. 
Therefore, a device’s actual 
  memory may be larger than the 32,767 MB (32 GB - 1 MB) reported by 
  SOAP.
