xups Dual Input Status

The present status of the sources of input power in a dual source UPS. The enumeration primarySourceGood(2) indicates that the primary source of power is present and within 'normal' ranges for voltage and frequency, but the secondary source is either not present or not in an acceptable range. The enumeration bothSourcesGood(4) indicates that both sources are present and within their respective 'normal' ranges; bothSourcesBad(1) indicates that neither source is present, or, if present, is not within acceptable ranges. This object will only be implemented for UPSs with two sources of input power, e.g., redundant AC feeds or a separate Bypass or Generator source. The secondary source will not be an AC power source in all cases.
