[0022] The lighting of the server hard disk refers to the multiple indicator lights on the server hard disk, which are used to display the working status of the hard disk. These indicator lights usually include different colors, and each color represents a different state of the hard disk. For example: green means that the power supply is normal and the server is in operation; yellow means that the server is in standby mode. In order to ensure the normal operation of the server hard disk and data security, it is necessary to check the status of the hard disk indicator light regularly. Therefore, the lighting control of the server hard disk in different states will be particularly important. In the related art, when performing the lighting control of the server hard disk, it is necessary to manually burn and configure the corresponding user flash memory according to different topological scenarios in advance, and then perform the lighting control. However, in the related art, the complexity of the lighting control is increased by manually burning and configuring the corresponding user flash memory according to different topological scenarios, thereby reducing the testing efficiency of the lighting control system.

Figure 3 As shown, the method includes:

[0109] In summary, the lighting control method provided in this embodiment obtains the hard disk presence signal of the hard disk device through the hard disk slot through the backplane logic device, encapsulates the hard disk presence signal into a communication reception frame, and sends the communication reception frame to the transmission unit; the transmission unit parses the communication reception frame to obtain the hard disk presence signal, determines the corresponding hard disk presence status according to the hard disk presence signal, and maps the hard disk presence status to the hardware device unit to complete the initialization of the hardware device unit. By initializing the hardware device unit, the foundation is laid for subsequent lighting control.

[0110] It should be noted that communication control frames and communication receive frames are collectively referred to as communication frames. Communication frames consist of two signal lines: the data line (SDA) and the clock line (SCL). The core timing is defined as follows: while the clock line remains high, a high-to-low transition of the data line indicates a start signal, and a low-to-high transition indicates a stop signal. Data is transmitted in bytes, using a MSB-first transmission mechanism. Each byte is followed by a single-bit acknowledgement signal. During the high-level period of the ninth clock cycle, a low data line indicates an acknowledgement (ACK), while a high data line indicates a negative acknowledgement (NACK). The I2C protocol format includes two basic communication modes: write mode and read mode.

[0111] The communication control frame corresponds to the write mode. In the write mode, the host sends the 7-bit slave address (the lowest bit LSB = 0 indicates a write operation). After the slave returns an ACK response in the 9th clock cycle, the host sends data byte by byte, and each byte requires an ACK confirmation from the slave.

[0112] The communication receiving frame corresponds to the read mode. In the read mode, the host sends the slave address (LSB=1), and starts sending data after the slave responds with an ACK. The host sends an ACK to maintain transmission or a NACK to terminate communication after receiving each byte. The above I2C protocol format, I2C write mode and I2C read mode are shown in detail. Figure 4 The I2C protocol diagram shown.

[0113] Through the description of the above implementation methods, those skilled in the art can clearly understand that the method according to the above embodiment can be implemented by means of software plus the necessary general hardware platform, and of course it can also be implemented by hardware, but in many cases the former is a better implementation method.

[0114] The above describes in detail a lighting control system and lighting control method provided by the present application. This article uses specific examples to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only intended to help understand the method and core concept of the present application. It should be noted that for ordinary technicians in this technical field, without departing from the principles of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the scope of protection of the claims of the present application.
