Abstract
A first device (such as a power supply) may detect a power anomaly and provide a warning to a second device that is powered by the first device. For example, if there are conditions indicating an increased likelihood of a power outage (e.g., a brownout period, one or more voltage spikes, etc.), then the first device may notify the second device, and in response, the second device may take protective action. Examples of protective action may include, but are not limited to, saving certain data (e.g., critical data) to non-volatile data storage, initiating a shut-down procedure, warning a user of the second device, etc. As the warning and/or other communications between the power supply and powered device may be wireless, various example techniques for wirelessly pairing the devices are also disclosed.
