The management IC supports multiple NCSI network devices. Using the management IC to control, users can switch network devices in the interactive module without reproducing boards and adjusting hardware, which increases product flexibility and saves costs.

The management IC is the management end of the NCSI bus, and the management IC in the system can use BMC. The switch module adopts a switch module with a control signal (the control signal is represented by SEL), and supports 6-bit input and output (the NCSI link contains 6 signals). The SEL signal is connected to the management IC, and there is an interactive interface between the management IC and the user. According to the user's choice, the high and low level output of the control signal SEL is realized, thereby controlling the opening and closing of the switch module, thereby gating the corresponding network equipment.

In this embodiment, when the PCB is wired, placing the switch modules close to each other can shorten the path branches generated between each other, and the path branches will affect the quality of the NCSI signal, so the position of the switch modules is arranged close to each other.

The human-computer interaction interface of the management IC makes all NCSI network devices a selection interface for users to choose according to their needs. In addition, the GPIO signal of the management IC corresponds to the control signal of the switch module, and all connected NCSI network devices need to correspond to the corresponding GPIO interfaces, as shown in the following table:

Table 1: Example of NCSI network device relationship diagram corresponding to GPIO status

Implement this relationship in the control command of the management IC. When it is used to select an NCSI network device, the corresponding GPIO needs to be set to enable the link of the secondary NCSI network device. For example, if the user selects NCSI network device 1, the management IC needs to set GPIO1 to 0, and the corresponding GPIOs of other NCSI network devices to 1 to close the link. After setting the GPIO, the management network needs to initialize the NCSI link to start normal NCSI network functions.
