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).

Have fun reading.

Cheers,
