A method of replacing a fan module during operation of an electronic apparatus, said method comprising the steps of:
- instructing a replacement of the fan module;
- controlling a fan drive voltage supplied to the fan module;
- turning off the fan drive voltage when the replacement is instructed;
- and
- confirming a state where a plurality of fan modules are installed, wherein
- the controlling step includes the step of controlling the fan drive voltage supplied to a fan module to be replaced if the replacement of a fan module is instructed during the state where the plurality of fan modules are installed.
A method of replacing a fan module during operation of an electronic apparatus, said method comprising the steps of:
- instructing a replacement of the fan module;
- controlling a fan drive voltage supplied to the fan module;
- turning off the fan drive voltage when the replacement is instructed;
- starting a timer count operation at a time when the fan drive voltage supplied to a fan module is controlled;
- and
- alerting an operator when a timer count value of the time count operation reaches a specified value.
An electronic apparatus capable of replacing a fan module during operation, comprising:
- means for instructing a replacement of the fan module;
- means for controlling a fan drive voltage that turns off the fan drive voltage supplied to a fan module to be replaced when the replacement is instructed;
- and
- means for detecting a state where a plurality of fan modules is installed, wherein
- the controlling means includes means for controlling the fan drive voltage supplied to a fan module to be replaced if the replacement of a fan module is instructed during the state where the plurality of fan modules are installed.
