Power Supply Profile Foreword The Power Supply Profile (DCIM1001) was prepared by the Dell CIM Review Board. 6 Version 1.0.
Power Supply Profile Introduction This specification identifies the necessary classes, properties, methods, and values to be instantiated and manipulated to represent and manage power supply modeled using the DMTF Common Information Model (CIM) core and extended model definitions. This document is intended for implementers who write CIM-based providers or consumers of management interfaces representing the component described herein. Version 1.0.
Power Supply Profile Power Supply Profile 1 Scope The Power Supply Profile extends the management capabilities of referencing profiles by adding the capability to represent power supplies for manageability and describe power supplies in a redundant configuration. The power supply as a logical device is modeled as referencing the power supply physical package for physical asset information and profile versioning for the schema implementation version information.
Power Supply Profile 3.1 can used for statements of possibility and capability, whether material, physical, or causal 3.2 cannot used for statements of possibility and capability, whether material, physical, or causal 3.3 conditional indicates requirements to be followed strictly in order to conform to the document when the specified conditions are met 3.4 mandatory indicates requirements to be followed strictly in order to conform to the document and from which no deviation is permitted 3.
Power Supply Profile 3.13 Spare Power Supply indicates an instance of CIM_PowerSupply that represents a spare power supply in any condition 4 Symbols and Abbreviated Terms 4.1 CIM Common Information Model 5 Synopsis Profile Name: Power Supply Profile Version: 1.0.0 Organization: Dell CIM Schema Version: 2.15.
Power Supply Profile CIM_PowerSupply instance supplies power to the managed system that is scoped through the CIM_SystemDevice association. The power supply’s physical aspects can be represented by one or more instances of CIM_PhysicalPackage. The profile information is represented with the instance of CIM_RegisteredProfile. RedundancySet ComputerSystem EnabledLogicalElementCapabilities 0..1 (See Referencing Profile) 0..1 1 MemberOfCollection 0..
Power Supply Profile 7 Implementation Requirements Requirements and guidelines for propagating and formulating certain properties of the classes are discussed in this section. Methods are listed in section 8 and properties are listed in section 10. 7.1 CIM_PowerSupply At least one instance of CIM_PowerSupply shall be instantiated. 7.
Power Supply Profile 7.4 CIM_PowerSupply.RequestedState The CIM_PowerSupply.RequestedState property shall have a value of 12 (Not Applicable), 5 (No Change), or a value contained in the CIM_EnabledLogicalElementCapabilities.RequestedStatesSupported property array of the associated CIM_EnabledLogicalElementCapabilities instance (see section 7.2.1).
Power Supply Profile 7.7 Modeling Power Supply Redundancy (Optional) Modeling of power supply redundancy is optional. Even when a managed system supports and implements the redundancy, the redundant power supplies may co-exist with non-redundant power supplies. The conditions and requirements in this section refer only to the CIM_PowerSupply instances that represent redundant power supplies.
Power Supply Profile 7.8.1 CIM_PowerSupply.ElementName Is Modifiable Implementations may allow the CIM_PowerSupply.ElementName to be modified by a client. This behavior is conditional. This section describes the CIM elements and behavior requirements when an implementation supports client modification of the CIM_PowerSupply.ElementName property. CIM_PowerSupply.
Power Supply Profile 7.10 Power Supply Profile Metrics (Optional) This section describes the Power Supply Profile metrics. The constraints in this section are in addition to the ones defined in DSP1053. The CIM_BaseMetricDefinition.Name property shall have the value specified in the column “Name”, and shall meet the requirements for one of the metrics type mentioned in the corresponding column “Supported Metrics” per DSP1053 if the metric matches the description in the column “Description”.
Power Supply Profile 8.1 Method: CIM_PowerSupply.RequestStateChange( ) Invocation of the CIM_PowerSupply.RequestStateChange( ) method will change the element’s state to the value that is specified in the RequestedState parameter. Return values for RequestStateChange( ) shall be as specified in Table 4 where the method-execution behavior matches the return-code description. RequestStateChange( ) method’s parameters are specified in Table 5.
Power Supply Profile 8.2 Method: CIM_RedundancySet.Failover( ) The CIM_RedundancySet.Failover( ) method forces a failover from one member of a CIM_RedundancySet collection to another. When the method executes successfully, the power supply that is represented by the CIM_PowerSupply instance referenced by the FailoverFrom parameter will become inactive. The power supply that is represented by the CIM_PowerSupply instance referenced by the FailoverTo parameter will take over as the active power supply.
Power Supply Profile Table 7 – CIM_RedundancySet.Failover( ) Method: Parameters Qualifiers Name Type Description/Values IN, REQ FailoverFrom CIM_ManagedElement REF The redundant element that will become inactive IN, REQ FailoverTo CIM_ManagedElement REF The redundant element that will become active and take over the inactivated element 8.3 Profile Conventions for Operations Support for operations for each profile class (including associations) is specified in the following subclauses.
Power Supply Profile 8.5 CIM_EnabledLogicalElementCapabilities Operations All operations in the default list in section 8.3 are supported as described by DSP0200 version 1.2. 8.6 CIM_IsSpare Operations Table 9 lists operations that either have special requirements beyond those from DSP0200, or shall not be supported.
Power Supply Profile 8.9 CIM_PowerSupply Operations Table 12 lists operations that either have special requirements beyond those from DSP0200, or shall not be supported. Table 12 – CIM_PowerSupply Operations Operation Requirement Messages ModifyInstance Optional. See section 8.9.1. None 8.9.1 CIM_PowerSupply—ModifyInstance This section details the requirements for the ModifyInstance operation applied to an instance of CIM_PowerSupply. The ModifyInstance operation may be supported.
Power Supply Profile 8.12 CIM_SystemDevice Operations Table 14 lists operations that either have special requirements beyond those from DSP0200, or shall not be supported.

Power Supply Profile 9.2 Power Sensor Information Figure 5 shows a possible instantiation of the Power Supply Profile including the power measuring sensors. Numsensor1, represents the numeric reading of Watts for the total power produced by all the power supplies of system1, pwrsupply1 and pwrsupply2. Each individual power supplies’ supplied power is represented by sensors numsensor3 and numsensor4.
