Description

Technical Field

[0001] This invention relates to the field of computers, and more specifically to a method, apparatus, device, and readable medium for preventing incorrect insertion of server cables. Background Technology

[0002] Due to the rapid development of internet services, the demand for servers is increasing. With the upgrade of the Intel platform, the demand for high-density servers and highly integrated servers is also growing, and there are more and more computing and storage servers.

[0003] With the increasing demand for servers, especially for dedicated servers, hardware designs are becoming more complex, and the integration of circuit boards is increasing, leading to a greater number of interconnecting cables between these boards. The development of heterogeneous servers and hybrid servers has also resulted in more connections between front-end and back-end servers, leading to increasingly complex structures and topologies. This increased complexity has created difficulties for production line operations, with frequent instances of improper or incorrect connections. Currently, complex high-density connectors only have cable insertion detection, which may result in incomplete connections. Heterogeneous servers often have multiple high-density cables connected at the front and back ends, making incorrect connections particularly easy. For example, cable A, intended for connector A, might be connected to connector B due to production line issues. Summary of the Invention

[0046] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to specific examples and the accompanying drawings.

[0047] Based on the above objectives, a first aspect of the embodiments of the present invention provides an embodiment of a method for preventing incorrect insertion of server cables. Figure 1 The diagram shown is a schematic flowchart of the method.

[0048] like Figure 1 As shown, the method may include the following steps:

[0049] S1 numbers the ports of the first and second components to be connected, and then numbers the pins within each port. For example... Figure 2 As shown, the first component can be a GPU, and the second component can be a CPU. The GPU has five ports, designated GPU_A through GPU_E, numbered 1 for GPU_A, 2 for GPU_B, and so on. The CPU also has five ports, designated CPU_A through CPU_E, numbered 1 for CPU_A, 2 for CPU_B, and so on. When the GPU and CPU are connected, ports with the same number are connected. Each port has multiple pins, which are numbered starting from 1, i.e., pin 1 is numbered 1, pin 2 is numbered 2, and so on.

[0050] S2 connects the pins with the same port number in the first component to the pins with a higher port number. That is, it connects the first pin of the first port in the first component to pin N, the second pin of the second port in the first component to pin N+1, the third pin of the third port in the first component to pin N+2, where N is greater than 1, and so on, completing the connection of the pins of each port in the first component. In the example above, when N is 3, pin number 1 in the GPU is connected to pin number 3, pin number 2 is connected to pin number 4, and pin number 5 is connected to pin number 7.

[0051] S3 grounds the pins in the second component that have the same port number as the port, and connects the pins in the first component whose pin numbers are greater than the port number to the first terminal of the corresponding indicator. That is, ground the first pin of the first port in the second component, connect the Nth pin to the first terminal of the first indicator, ground the second pin of the second port in the second component, connect the N+1th pin to the first terminal of the second indicator, ground the third pin of the third port in the second component, connect the N+2th pin to the first terminal of the third indicator, and so on, completing the pin connection for each port of the second component. In the example above, when N is 3, ground the pin numbered 1 in the CPU, connect the pin numbered 3 to the first terminal of the first indicator, ground the pin numbered 2 in the CPU, connect the pin numbered 4 to the first terminal of the second indicator, ground the pin numbered 5 in the CPU, and connect the pin numbered 7 to the first terminal of the fifth indicator. In the above two steps, the pins used for ports with the same number in the GPU and CPU are the same, and each port uses one indicator, which can be a light-emitting diode (LED).

[0052] The second terminal of the corresponding indicator of S4 is connected to the power supply via a resistor.

[0053] Finally, connect the corresponding ports using cables, such as... Figure 3 and Figure 4 As shown, in port A, the LED (light-emitting diode) will light up after power-on when the cable is fully inserted. Pins 1 and 2 can be shorted so that the LED will only light up when the cable is fully inserted, which can help determine if the cable is not inserted correctly or is misaligned. In port B, the LED will light up after power-on when the cable is fully inserted. The connection pins are modified to Pin 2 and Pin N+1. If the cable from port A is plugged into port B, the LED will not light up, allowing you to visually determine if the cable is plugged in incorrectly.

[0054] By using the technical solution of the present invention, the problem of improper insertion of high-density or multi-pin high-speed connectors can be solved, as can the problem of incorrect insertion of internal cables or cables between servers.

[0055] In a preferred embodiment of the present invention, connecting a pin with the same port number as the port number in the first component to a pin with a pin number greater than the port number includes:

[0056] Connect the first pin of the first port in the first component to the Nth pin;

[0057] Connect the second pin of the second port in the first component to the N+1th pin;

[0058] Connect the third pin of the third port in the first component to the (N+2)th pin, where N is greater than 1, and so on to complete the pin connection for each port of the first component. In the example above, when N is 3, connect pin number 1 in the GPU to pin number 3, pin number 2 to pin number 4, and pin number 5 to pin number 7.

[0059] In a preferred embodiment of the present invention, grounding the pin with the same port number in the port of the second component, and connecting the pin corresponding to the pin with a greater port number in the port of the first component to the first terminal of the corresponding indicating device includes:

[0060] Ground the first pin in the first port of the second component, and connect the Nth pin to the first end of the first indicator device;

[0061] Ground the second pin in the second port of the second component, and connect the N+1th pin to the first end of the second indicator device;

[0062] Ground the third pin of the third port in the second component, connect the N+2th pin to the first end of the third indicator, and so on to complete the pin connection of each port of the second component. In the example above, when N is 3, ground the pin numbered 1 in the CPU, connect the pin numbered 3 to the first end of the first indicator, ground the pin numbered 2 in the CPU, connect the pin numbered 4 to the first end of the second indicator, ground the pin numbered 5 in the CPU, and connect the pin numbered 7 to the first end of the fifth indicator.

[0063] In a preferred embodiment of the present invention, the indicating device includes a light-emitting diode.

[0064] In a preferred embodiment of the present invention, the BMC is connected to the first or second terminal of the indicating device. When the BMC detects a high level, it is determined that the cable is incorrectly inserted or not fully inserted; when the BMC detects a low level, it is determined that the cable is inserted correctly or is fully inserted.

[0065] By using the technical solution of the present invention, the problem of improper insertion of high-density or multi-pin high-speed connectors can be solved, as can the problem of incorrect insertion of internal cables or cables between servers.
