1. A non-transitory computer-readable storage medium that stores one or more sequences of instructions for detecting an imminent failure in a power supply, which when executed by one or more processors, cause:
an internal computerized component, disposed within a device comprised within an outer housing, periodically reading a set of measurements from one or more sensors affixed to said power supply also disposed within said outer housing and storing at least a portion of the set of measurements read from said one or more sensors as a stored set of measurements, wherein the power supply is not disposed within said device, and wherein said outer housing provides a hermetically sealed environment;
the internal computerized component analyzing said set of measurements and said stored set of measurements using, at least in part, a weighted set of factors, to detect the imminent failure in said power supply based upon, at least in part, detecting an exponential acceleration of rising temperature and equivalent series resistance (ESR) in at least one electrolytic capacitor of said power supply; and
the internal computerized component periodically informing a cable headend of said set of measurements and/or said stored set of measurements.
