- step S4 If a positive determination result is obtained in step S4, the expander 50 starts a protocol link on the condition that the response signal 402 has been received (S10), and recognizes the mounting of the drive 52 mounted on the module.
- step S11 the microcontroller 220 determines whether a low-level fan module signal 410 is detected from the module.
- step S12 When a positive determination result is obtained in step S12, that is, when a signal indicating that the fan module signal 410 is detected is received from the microcontroller 220, the expander 50 recognizes the module as the fan-equipped drive module 70 (S13). ), The location of the fan-equipped drive module 70 is recognized on the basis of the response signal 402 from the module, and the ID of the drive 52 is recognized on the basis of the recognized location (S14), and then becomes an idle state (S15). The process returns to step S1.
- step S12 when a negative determination result is obtained in step S12, if the microcontroller 220 does not detect the low level fan module signal 410 from the module, the expander 50 recognizes the module as the drive module 120 (S16). ) Recognizes the location of the drive module 120 based on the response signal 402 from the module, recognizes the ID of the drive 52 based on the recognized location (S17), and then enters the idle state (S18), step S1. Return to the process.
- FIG. 13 is a flowchart for explaining the expander temperature management method.
- the expander 50 periodically collects drive temperature information from an internal temperature sensor built in each drive 52 (S 21), and uses the collected drive temperature information as a detected temperature of each drive 52.
- Information (temperature 512) is updated (S22), and it is determined whether or not the detected temperatures of all the drives 52 are equal to or lower than the temperature threshold Tth (S23).
- step S23 When an affirmative determination result is obtained in step S23, the expander 50 executes a process for collecting drive temperature information from each drive 52 (S24), and returns to the process of step S21.
- step S23 when a negative determination result is obtained in step S23, that is, when the temperature of at least one drive 52 exceeds the temperature threshold Tth, the expander 50 detects that the detected temperature exceeds the temperature threshold Tth. It is determined whether or not there is a fan (S25).
- step S25 the expander 50 sets the fan rotation speed corresponding to the drive temperature for the fan of the module in which the high temperature drive 52 is mounted (S26). Then, the rotational speed of the fan is read (S27), and it is determined whether or not the rotational speed of the fan is the set rotational speed (S28).
- step S28 If an affirmative determination result is obtained in step S28, the expander 50 starts a process for collecting drive temperature information (S29), and then returns to the process of step 21 and obtains a negative determination result in step S28. If this is the case, exception processing as fan abnormality, for example, processing for generating an alarm is executed (S30), and processing in this routine is terminated.
- step S25 the expander 50 determines whether or not the fan module 100 is mounted in the coolable area in which the high-temperature drive is disposed (S31). .

- step S34 When the expander 50 obtains a negative determination result in step S34, the expander executes exception processing as a fan abnormality (S30), thereafter ends the processing in this routine, and obtains a positive determination result in step S34. In this case, the process for collecting the temperature information of the drive 52 is started (S35), and the process returns to step S21.
- step S31 when a negative determination result is obtained in step S31, that is, when it is impossible to cool the high temperature drive, the expander 50 executes a process for issuing a warning to the CPU 32 (S36). Thereafter, a process for collecting temperature information of the drive 52 is started (S37), and the process returns to step S21.
