When the interior temperature inside a line accommodating apparatus (100) measured by an apparatus-interior temperature sensor (103) is equal to or higher than a predetermined first threshold value, a control unit (105) shuts off the supply of power from a power supply unit (102) to a line module (101-1, 101-2) having a module temperature, measured by a module temperature sensor (104), higher than the sum of a predetermined second threshold value and the interior temperature. |
