As shown in fig. 3, first, the preset level output terminal (AIRDUCT _ POWEROFF _n) of the baseboard management controller 1 outputs a high level (high), when the wind scooper 2 is not mounted on the motherboard 6 (not mounted), or when the wind scooper 2 is not mounted on the motherboard 6 (not mounted), the second conductive metal sheet group (i.e. the third conductive metal sheet 41 and the fourth conductive metal sheet 42) on the motherboard 6 is opened, and is in an unconnected state, the switch unit MOS Q193 is turned on, so that the detection input terminal AIRDUCT _n is changed from a low level to a high level (the voltage value of the high level of the detection input terminal AIRDUCT _n is smaller than the voltage value of the high level of the level output terminal AIRDUCT _ POWEROFF _n), and the wind scooper is not mounted, so as to alarm by the alarm module 8.
As shown in fig. 4, first, the preset level output terminal (AIRDUCT _ POWEROFF _n) of the baseboard management controller 1 outputs a high level (high), when the installation of the wind scooper 2 on the motherboard 6 is completed (after the installation of the first conductive metal sheet group on the wind scooper 2 and the second conductive metal sheet group on the motherboard 6 are completed, the second conductive metal sheet group (i.e. the third conductive metal sheet 41 and the fourth conductive metal sheet 42) on the motherboard 6 is shorted, and is in a connection state, so that the detection input terminal AIRDUCT _n is changed from a high level to a low level, then the baseboard management controller 1 adjusts the output of the preset level output terminal (AIRDUCT _ POWEROFF _n) to a low level (low), and the switch unit MOS transistor Q193 is turned off, then the installation of the wind scooper 2 is completed, and then the detection of whether the other wind scoopers 2 are installed is continued.

In the related art, the server generally only uses naked eyes to judge whether the wind scooper is installed or not, but often shifts or forgets to install in the subsequent assembly process, so that subsequent testing or business forwarding is caused, if the technical scheme of the utility model is used, not only can the heat dissipation problem caused by the wind scooper be rapidly confirmed, but also the subsequent linkage event caused by the incomplete installation of the wind scooper such as poor assembly can be avoided, and under the condition that a system does not cover, a user can easily grasp whether the installation state of the wind scooper is abnormal through the BMC, so that the detection of the installation state of the wind scooper is realized, the high risk caused by judging whether the installation state of the wind scooper is good or not only by manpower is avoided, and further, starting up under the condition of abnormal heat dissipation is avoided, and more system errors are caused subsequently.
Preferably, the gate of the MOS transistor Q193 is further electrically connected to the power VCC through a second resistor (resistor 1), so as to ensure that the gate of the MOS transistor Q193 is in a high-level state at all times during the level power-up process of the level output end of the baseboard management controller 1, and still can reliably detect the installation condition of the wind scooper.
