Property Description
• 15 = Storage Media Package (example, Disk or Tape Drive)
• 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 different than the MIB's values. The values
"Rack" through "Port/Connector" are defined 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 differently by
inventory systems and differs 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.
SerialNumber
A manufacturer-allocated number used to identify the Physical Element.
SKU
The stock-keeping unit number for this PhysicalElement.
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.
Version
A string that indicates the version of the PhysicalElement.
DCIM_ParallelPort
Property Description
BaseIOAddress
An integer value that represents the base I/O address used by the
parallel port.
ConnectorType
ConnectorType is defined to force consistent naming of the 'connector
type' property in subclasses and to guarantee unique enum values for
all instances of ParallelPort. When set to 3 ("Proprietary"), the related
property OtherConnectorType contains a string description of the type
of port.
