Hi Ed, the presence I am talking about is kind of a logical concept. You
can find the dbus and redfish properties in the proposal. I believe we plan
to use the following mappings,

dbus                             redifish
 logical
State(enabled)       Device#Status#State             If state is "enabled",
the device is considered present.
Health(OK)            Device#Status#Heatlth(OK)   If health is "OK", the
device is considered present and its current status is OK (its power should
be OK at least).
