+ *      none(2) indicates that there is no source of output
+ *      power (and therefore no output power), for example,
+ *      the system has opened the output breaker.
+ *
+ *      NOTE: In a single-module system, this point
+ *      is intended to have the same behavior as
+ *      the RFC1628 point upsOutputSource."
