After the preset type hard disk label is pasted, the second contact switch is connected, the second type identification channel is conducted at the same time, when the first power supply passes through the second resistor and is used as the second input end of the first AND gate logic unit, the voltage at the moment is smaller than the voltage provided by the second power supply, at the moment, the first input end of the AND gate logic unit is connected with the first type identification channel, so that no signal input at the first input end is negligible, the input end of the first AND gate logic unit is low, the low level is output, and the output end of the first AND gate logic unit is low.

At this time, the input of the decision module of the other cable installation position recognition device has a high level, so the first output end of the nor gate logic unit of the cable installation position recognition device outputs a high level, and the corresponding indicator lamp is lightened at this time.
According to the embodiment, the disk array card identification module is arranged on the normal disk array card bracket and is only used for identifying whether the disk array card is arranged or not, and the original physical structure and functions are not affected.
