+This GPIO value represents the status of standby power regulator fault detection
+logic. This GPIO is an input only. The status will reflect a regulator
+non-faulted condition after AC power cycle when no standby power regulator fault
+condition is present. The status will reflect a standby regulator power faulted
+condition when an unexpected drop in standby power is detected.
