Background
In the field of servers, status indicators are disposed on a backplane having a hard disk to indicate the status of the hard disk on the backplane, and the status of the hard disk may include in-service status, undetected status, error status, rebuilt status, and location status. The status of the hard disk is usually determined by the server host, and the control unit transmits a corresponding signal to the control unit on the backplane through the SGPIO and I2C interfaces, and the control unit controls the status indicator lamp to indicate the status of the hard disk accordingly.

For the example of fig. 1, if the look-up table indicates that the first voltage level corresponds to the first lighting information and the second voltage level corresponds to the second lighting information, when the control unit Crl1 detects the first voltage level at the detection end Det1, the control unit Crl1 will correspondingly retrieve the portion of the lighting configuration signal related to the first lighting information according to the look-up table, and when the control unit Crl2 detects the second voltage level at the detection end Det2, the control unit Crl2 will correspondingly retrieve the portion of the lighting configuration signal related to the second lighting information. In some embodiments, the detector Det1 is an ADC pin of the control unit Crl1, and the detector Det2 is an ADC pin of the control unit Crl2, for converting the first voltage level and the second voltage level into digital signals to determine the voltage level.
After the control unit Crl1 obtains the first light-emitting information, the control unit Crl1 decodes the first light-emitting information to drive the light-emitting units LED 1-LED 4. Similarly, when the control unit Crl2 obtains the second light information, the control unit Crl2 decodes the second light information to drive the light units LED 5-LED 8.

Even if the number of the back boards needs to be adjusted, only different voltage levels need to be set and the corresponding relation in the corresponding table needs to be modified, and a complex decoding mode is not needed, so that the server system has design flexibility and expandability.
