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
