Abstract
A power supply control device controls power supplied via a power supply switch. An IPD turns the power supply switch on or off. A first power supply controller transmits an ON signal and an OFF signal a first device communication line. The ON signal instructs to turn on the power supply switch. The OFF signal instructs to turn off the power supply switch. If the first power supply controller determines that communication via the first device communication line is interrupted, a second power supply controller transmits the ON signal and the OFF signal to the IPD via a second device communication line.
