Abstract
The present disclosure provides a hard disk indicator circuit and a hard disk backplane. The hard disk indicator circuit includes an indicating unit, a control unit, a drive unit and a verification unit. The indicating unit indicates state of the hard disk. The control unit detects the state of the hard disk and outputting a control signal according to the state of the hard disk. The drive unit receives the control signal and lights the indicating unit according to the control signal. The verification unit obtains a level value of the indicating unit and determines whether the indicating unit is faulty according to the level value and the control signal. The present disclosure can quickly and accurately obtain the fault state of the hard disk indicator, save manpower and improve the fault detection efficiency.
