Abstract:

   This document defines a YANG data model that augments the system
   capabilities model of RFC 9196 to allow a network element to
   advertise, per hardware Component, the set of Power States that the
   Component supports, together with a static characterization of each
   such state: the expected and maximum Power the Component draws in it,
   and the time to enter and exit it.

   This capability model complements the operational Power and Energy
   data model defined in the GREEN Power and Energy YANG module, which
   reports the current Power State and the measured Power of a
   Component, but not which Power States are available, how much Power
   each draws, or how long transitions between them take.  It is
   anchored to the hardware inventory of RFC 8348, reuses the Power
   State identities of the GREEN Power and Energy model, and, because it
   is static, may be provided at implementation time as YANG instance
   data per RFC 9195 so that an Energy Management System can learn a
   platform's Power State capabilities before the equipment is deployed
   or even powered on.
