ABSTRACT:
An abnormal temperature detector for an electronic apparatus includes a plurality of temperature detectors, an abnormality detector, and a power supply controller. The plurality of temperature detectors are arranged at least at one detection point of a rack, of an electronic apparatus, in which a plurality of wiring boards having IC elements mounted thereon are housed, and respectively output detection outputs when a temperature at the detection point becomes a preset temperature or more. The abnormality detector detects that detection outputs are output from all the temperature detectors at the detection point. The power supply controller interrupts a power supply of the apparatus in response to an abnormality detection output from the abnormality detector.
