    Hi Everyone,

    Thanks so much for answering!

    I'm not sure if it is best that we continue to restrict what we define in the CIM model for print to be directly mapped to print MIB. Microsoft believes that in the future it will be important to be able to control device power management remotely using WS-Management.

    We believe that the PWG should consider looking at the existing DMTF power management classes to determine if they are appropriate.

    Definitely a topic for discussion next week. Mike Fenelon will be representing Microsoft.

    Thanks,
    Erhan

    Hi Nancy,

    Copying WIMS list so others can comment.

    CIM_PowerManagementService is a feature of a CIM_ComputerSystem
    - i.e., we inherited it from standard DMTF CIM profiles when we modelled
    a network printer as a CIM_Printer contained in a CIM_ComputerSystem
    (class corresponds to System group in MIB-II and Host Resources MIB).

    Since the Printer MIB has no power management and I can't find
    any IETF standards-track MIB that has power management, a CIM
    Printing Provider (SNMP to CIM proxy) can't implement power
    management interoperably.

    A basic principle of the WIMS-CIM project is "we invent nothing new"
    - so we can look at existing standard DMTF power management
    classes and see if they're appropriate, but SNMP mapping will remain
    proprietary in the near term.

    For future PWG work, I think PowerManagement is important - it *is*
    already in the new Projector and Display Management MIB - perhaps
    a topic for discussion at the PWG F2F next Wednesday?

    Cheers,
    - Ira

    Cheers,
    - Ira
