    Hi folks,

    Link to EuP Final Directive on EcoDesign of 6 July 2005

      http://europa.eu/eur-lex/lex/LexUriServ/site/en/oj/2005/l_191/l_19120050722en00290058.pdf

    Link to ITU-T (2009-2012) charter for Management of Transport
    Systems (i.e., networks and network devices):

      http://www.itu.int/ITU-T/studygroups/com15/sg15-q14.html

    which lists the power management task:

      Revise Recommendation G.7710/Y.1701, Common Management
      Requirements, including requirements for power saving modes

    Link to final (for PURCHASE) IEEE 1621-2004
    " IEEE Standard for User Interface Elements in Power Control of
    Electronic Devices Employed in Office/Consumer Environments":

      http://ieeexplore.ieee.org/xpl/freeabs_all.jsp?tp=&isnumber=31207&arnumber=1453037&punumber=9863

    Which is the basis of DMTF CIM_PowerManagementCapabilities
    property "PowerStatesSupported" enumeration:

           Values { "Other", "On", "Sleep - Light", "Sleep -Deep",
              "Power Cycle (Off - Soft)", "Off - Hard",
              "Hibernate (Off - Soft)", "Off - Soft",
              "Power Cycle (Off-Hard)", "Master Bus Reset",
              "Diagnostic Interrupt (NMI)", "Off - Soft Graceful",
              "Off - Hard Graceful", "Master Bus Reset Graceful",
              "Power Cycle (Off - Soft Graceful)",
              "Power Cycle (Off - Hard Graceful)",
              "Diagnostic Interrupt (INIT)", "DMTF Reserved",
              "Vendor Specific" },
           MappingStrings { "IEEE P1621 | 3.2" },

    Also see the "PowerCapabilities" property:

           Values { "Unknown", "Other",
              "Power Saving Modes Entered Automatically",
              "Power State Settable", "Power Cycling Supported",
              "Timed Power On Supported" },
           MappingStrings { "MIF.DMTF|System Power Controls|001.2" },

    And the "PowerChangeCapabilities" property:

           Values { "Unknown", "Other",
              "Power Saving Modes Entered Automatically",
              "Power State Settable", "Power Cycling Supported",
              "Timed Power On Supported",
              "Off Hard Power Cycling Supported", "HW Reset Supported",
              "Graceful Shutdown Supported" },
           ModelCorrespondence {
              "CIM_PowerManagementService.RequestPowerStateChange",
              "CIM_PowerManagementCapabilities.OtherPowerChangeCapabilities" }]

    The key CIM classes that apply to any element (typically system or device):

      CIM_PowerAllocationSettingData
      CIM_PowerManagementCapabilities
      CIM_PowerManagementService

    So, DMTF CIM has a standard set of power states and power
    change capabilities. WIMS WG should consider these and map
    to/from them in any PWG best practice or standard on power
    management for Imaging Systems (for Web Services access).

    Link to current DMTF CIM v2.20 Schema release:

    Have fun reading.

    Cheers,
