+    Implement to describe the status of the power supplied to the chassis by the
+    power supply unit(s). It is expected that the relationship to the chassis is
+    shown by implementing this interface under a multi-object path, such as
+    chassisN/unit[N] where unit can be an individual or group.

+    - name: Status
+      type: enum[self.Status]

+        The current status of the power being supplied to the chassis.

+         The power supply unit(s) are not providing enough power for normal
+         chassis operation, such as in a Brownout/Blackout condition where one
+         or more power supplies report AC loss VIN fault.
