Since the debugging of each subsystem is performed through the display port, i.e., the VGA port, if a server includes 4 subsystems, 4 VGA ports are required, and if there are more, the number of VGA ports required correspondingly increases, with the attendant increase in complexity and risk of testing the VGA ports.
Therefore, the embodiment of the application provides a VGA port selection scheme, which can reduce the test complexity and risk of the VGA port and improve the test efficiency.
The embodiment of the application discloses a VGA port selection method, and as shown in FIG. 2, the method comprises the following steps:

It should be noted that, in the embodiment, the target server includes a plurality of subsystems, each subsystem has a VGA port, each VGA port has a corresponding VGA signal line therein, and the embodiment transmits a corresponding VGA signal through the VGA signal line. Correspondingly, the Switch selector acquires the output signal of each VGA port through the VGA signal line.
Step S12: and screening the output signals of all the VGA ports through a Switch selector to screen out target output signals, and determining the VGA port of the target output signals as a target VGA port.
It should be noted that the Switch selector has two states: on or off. In this embodiment, the Switch state of the VGA port of the target output signal is set to the on state by the Switch selection function in the Switch selector, so that the VGA port of the target output signal is determined to be the target VGA port. That is, based on the multiple inputs of the Switch selector, the characteristics of the output are selected, and one VGA port is determined from the VGA ports corresponding to the subsystems in the target server.
The number of subsystems in the target server in this embodiment includes, but is not limited to, four or eight. In a specific embodiment, if there are four subsystems in the target server, corresponding to four VGA ports, the present application sets the switch state of one VGA port to the on state, so as to set the VGA port in the on state as the target VGA port, and similarly, in another specific embodiment, if there are eight subsystems in the target server, corresponding to eight VGA ports, the application sets the VGA port in the open state as the target VGA port by setting the switch state of one VGA port to the open state, at the moment, only one subsystem carries out display output, and only one VGA port needs to be tested and protected, so that, for a server with four subsystems, the method optimizes the existing technical scheme of testing and protecting four VGA ports into the method of testing and protecting only one VGA port; for a server with eight subsystems, the existing technical scheme that eight VGA ports need to be tested and protected is optimized to be that only one VGA port needs to be tested and protected, so that the test complexity and the risk of the VGA ports are reduced and the test efficiency is improved by reducing the number of the VGA ports which are externally output and displayed.
Therefore, the present application provides a VGA port selection method, including: determining VGA ports of all subsystems in a target server, and acquiring output signals of all the VGA ports; and screening the output signals of all the VGA ports through a Switch selector to screen out target output signals, and determining the VGA port of the target output signals as a target VGA port. Therefore, the multi-path input and output characteristics of the Switch selector are selected, and one VGA port is determined from the VGA ports corresponding to all the subsystems in the target server, so that only one VGA port needs to be tested, the test complexity and the risk of the VGA port are reduced, and the test efficiency is improved.

Step S22: and screening the output signals of all the VGA ports through a Switch selector to screen out target output signals, and determining the VGA port of the target output signals as a target VGA port.
It should be noted that, by setting the Switch state of the VGA port of the target output signal to the on state through the Switch selection function in the Switch selector, the VGA port of the target output signal is determined as the target VGA port. That is, based on the multiple inputs of the Switch selector, the characteristics of the output are selected, and one VGA port is determined from the VGA ports corresponding to the subsystems in the target server.

In this embodiment, by disposing a protection device on the signal line of the target VGA port, the output signal of the target VGA port is correspondingly protected. Specifically, by arranging a surge protection device, an electrostatic protection device and a filter device on a signal line of the target VGA port, the output signal of the target VGA port is correspondingly protected. Because this application only needs to protect a VGA port, consequently this application greatly reduced the protection cost.
Therefore, the present application provides a VGA port selection method, including: determining VGA ports of all subsystems in a target server, and acquiring output signals of all the VGA ports; screening the output signals of all the VGA ports through a Switch selector to screen out target output signals, and determining the VGA port of the target output signals as a target VGA port; the method comprises the steps of carrying out corresponding signal protection on a target output signal in a target VGA port, selecting output characteristics based on multi-path input of a Switch selector, and determining a VGA port from VGA ports corresponding to subsystems in a target server.
