Abstract
Apparatus and methods are provided. A system includes two or more power supplies receiving electrical energy from respective independent sources. One of the power supplies detects an anomalous condition of the associated energy source and provides an alert signal. At least one of the other power supplies transitions from a standby mode to a normal output mode in response to the alert signal. The failing power supply provides operating level energy to an electrical load while the one or more other power supplies transition from standby to normal output level.
