Hot-plug protection systems and devices with status indicators

A method, comprising:

• measuring, by a protection circuit, a value of a property associated with a load coupled to the protection circuit;
• determining, by the protection circuit, that the measured value of the property exceeds a protection threshold;
• in response to determining that the measured value of the property exceeds the protection threshold,
• taking, by the protection circuit, a protection action, and
• sending, by the protection circuit, a first signal indicative of the measured value of the property exceeding the protection threshold to a controller;
• and
• controlling, by the controller, a light emitting device to emit a corresponding light beam with a corresponding characteristic based on at least the first signal, wherein the light emitting device is configured to emit a plurality of light beams with a plurality of characteristics including the corresponding characteristic, and the plurality of light beams comprises the corresponding light beam.

A device, comprising:

• a protection circuit configured to be coupled to a load, wherein the protection circuit is configured to:
• measure a value of a property associated with the load,
• determine whether the measured value of the property exceeds a protection threshold, and
• take a protection action in response to determining that the measured value of the
• property exceeds the protection threshold;
• a controller coupled to the protection circuit;
• and
• a light emitting device coupled to the controller and configured to emit a plurality of light beams with a plurality of characteristics,
• wherein the protection circuit is further configured to:
• in response to the measured value of the property exceeding the protection
• threshold, send a first signal indicative of the measured value of the property exceeding the protection threshold to the controller;
• and
• send a second signal indicative of the measured value of the property to the controller, and
• wherein the controller is configured to:
• determine at least one of one or more events based on at least one of the first signal or the second signal;
• and
• for each of the one or more events, control the light emitting device to emit a
• corresponding light beam of the plurality of light beams with a corresponding characteristic of the plurality of characteristics.
