The present invention relates to an indicator light control system, in particular to a server hard disk indicator light control system and a control method thereof.

In a server system, it is common to connect a hard disk storage unit on the backplane to facilitate data storage of the server system or other technical service application and management requirements. In order to conveniently know and immediately grasp whether the operation of the hard disk storage unit is abnormal, the operation status of the hard disk storage unit is displayed through a hard disk status indicator (LED). Generally speaking, in a server system, the hard disk status indicators are mostly installed on the back panel, and the light source is guided through a light guide column (such as a light pipe) to a position that can be seen by the user, such as guiding the light source to the hard disk. On the tray or directly on the hard disk storage unit, it is convenient for the user to directly see the lighting of the hard disk status indicator light to know the operating status of the hard disk. However, the installation of the light guide column not only increases the production cost, but also needs to consider the wiring position in the internal installation space, and the installation is complicated and inconvenient. Although there are designs that directly dispose the hard disk status indicator on the hard disk storage unit, generally, only a few hard disk status indicators (LEDs) can be installed on the hard disk storage unit, and The hard disk status indicator will only display monotonically flickering or on-off status, and can only display several basic operating statuses of the hard disk storage unit.
