A power supply is configured to accept battery and external power sources, and is adapted for use in equipment in a broadband communications network. A first voltage detector detects a first voltage signal at an electrical path associated with the battery power source and a second voltage detector detects a second voltage signal at an electrical path associated with the external power source. A processor is responsive to the first and second voltage detectors and adapted to generate an electrical signal indicating whether the battery power source is present, charged and being used. A light emitting diode, responsive to the processor, displays, in an order of priority, whether the battery power source is present, charged or being used.
