Figure 4 As shown in FIG. 10, assuming that the detection circuit in the server node obtains ID0 as low and ID1 as low by detecting the on-off state of PIN02 and PIN13, the processing unit will determine that the on-off state of PIN02 in the connector unit connected to the server node in the cable backplane is disconnected and the on-off state of PIN13 is disconnected according to ID0 as low and ID1 as low. Assuming that the code table is the code table shown in Table 1, the processing unit can query the code table shown in Table 1 according to the code of PIN02 and PIN13, so that the ID value corresponding to the code is 00, and thus the slot number of the server node in the server cabinet can be determined as 00. Figure 4 Figure 4 Figure 4

[0111] ​​​It can be seen that, by using the embodiment of the application, the server node can automatically acquire the pass / fail code corresponding to the connector unit in the cable backplane by detecting the pass / fail of the connector unit connected in the cable backplane, and can acquire the slot number corresponding to the pass / fail code by querying the code table, so that the server node can accurately determine the slot number of itself in the server cabinet.

[0112] Please refer to Figure 5 , Figure 5 is a flowchart of a detection method 102 of a cabinet server cable connection provided by the embodiment of the application. Different from the method shown in Figure 2 and Figure 3 , the method shown in Figure 5 specifically describes that the identity information of the connector unit connected by the server node in the cable backplane is the information carrier outside the target slot in the server cabinet. As Figure 5 shown, the detection method 102 of the cabinet server cable connection can include but is not limited to the following steps:

[0113] S501, the server node acquires the information carrier of the target slot in the server cabinet, and the information carrier is used to indicate the identity information of the connector unit connected by the server node in the cable backplane;

[0114] Among the target slot in the server cabinet, the connector unit connected by the server node in the cable backplane is included; the information carrier is preset outside the target slot in the server cabinet.

[0115] Optionally, the information carrier includes an NFC tag, a bar code, a two-dimensional code, etc.

[0116] It can be understood that the server cabinet includes at least one slot, and one information carrier is respectively preset outside each slot.

[0117] S502, the server node identifies the information carrier to determine the first slot number of the server node in the server cabinet.

[0118] Optionally, when the information carrier is an NFC tag, an NFC reader can be placed in the server node, so that the server node can acquire the information in the NFC tag through the NFC reader.

[0119] Exemplarily, please refer to Figure 6a , Figure 6a is a schematic diagram of an information carrier for setting a node slot in a server cabinet provided by the embodiment of the application. As Figure 6aAs shown in the figure, the information carrier of the node slot is on the right side of the whole server cabinet; the information carrier is an NFC tag; and the server node end is provided with an NFC reader. The server node can obtain the NFC tag through the NFC reader, identify the NFC tag, and obtain information in the NFC tag. The information includes the slot number corresponding to the NFC tag in the whole server cabinet. Thus, the server node can determine that the slot number corresponding to the NFC tag in the server cabinet is the first slot number of the server node in the server cabinet.

[0120] Optionally, when the information carrier is a bar code or a two-dimensional code, a micro code scanner can be arranged in the server node, so that the server node obtains information in the bar code or the two-dimensional code through the micro code scanner.

[0121] For example, refer to Figure 6b , Figure 6b Another schematic diagram of the information carrier of the node slot provided in the server cabinet is provided in the embodiments of the present application. As shown in the figure, Figure 6b The information carrier of the node slot is on the right side of the server cabinet; the information carrier is a bar code or a two-dimensional code; and the server node end is provided with a micro code scanner. The server node can scan the bar code or the two-dimensional code through the code scanner, obtain the bar code or the two-dimensional code, identify the bar code or the two-dimensional code, and obtain information in the bar code or the two-dimensional code. The information includes the slot number corresponding to the bar code or the two-dimensional code in the whole cabinet. Thus, the server node can determine that the slot number corresponding to the bar code or the two-dimensional code in the server cabinet is the first slot number of the server node in the server cabinet. Optionally, the bar code or the two-dimensional code can be pre-stuck on a position with a certain degree of recess in the cabinet. In this way, on the one hand, enough scanning distance can be left to enable the micro code scanner in the server node to scan the bar code or the two-dimensional code; on the other hand, the bar code or the two-dimensional code can be prevented from being damaged due to human or environmental reasons.

[0122] As can be seen, in the embodiments of the present application, the server node can obtain the information carrier of the node slot, identify the information carrier, and thus determine the first slot number of the server node in the server cabinet.

[0123] Optionally, the methods shown in the above Figure 2 , Figure 3 and Figure 5 can be applied to the whole cabinet server using a cable backplane, so that the server node can accurately determine the position of the connector unit connected by the server node in the cable backplane, and thus obtain the accurate node slot number of the server node in the server cabinet.

[0124] For example, refer to Figure 7 , Figure 7is a flowchart of a method for detecting a server cabinet cable connection 200 provided by an embodiment of the present application. Compared with the method for detecting a server cabinet cable connection shown in Figure 2 or Figure 3 or Figure 5 the method shown in Figure 7 the method shown in Figure 7 the method for detecting a server cabinet cable connection 200 can include but is not limited to the following steps:

[0125] S701, the server node sends a first slot number to the cabinet management board, and correspondingly, the cabinet management board receives the first slot number from the server node.

[0126] The cabinet management board is configured to determine whether to send an alarm information according to the first slot number and a second slot number of the server node in the server cabinet, and the alarm information is used to indicate that the first slot number and the second slot number are inconsistent, and the second slot number is determined by the cabinet management board by analyzing a link layer discovery protocol (LLDP) message of a switch.

[0127] The first slot number is determined by the server node according to identity information of a connector unit connected in a cable backplane, and the first slot number is used to indicate a position of the connector unit connected in the cable backplane.

[0128] Optionally, before step S701, the server node can also determine the first slot number. Optionally, the server node can determine the first slot number by the method shown in Figure 3 or Figure 4 Optionally, the first slot number can also be called an accurate slot number.

[0129] S702, the cabinet management board analyzes a link layer discovery protocol (LLDP) message of a switch, and determines a switch port identifier corresponding to the server node based on the analyzed LLDP message, wherein the switch and the server node are connected.

[0130] S703, the cabinet management board queries a preset list according to the switch port identifier, obtains a slot number corresponding to the switch port identifier, and takes the slot number corresponding to the switch port as a second slot number of the server node in the server cabinet.

[0131] The slot number corresponding to the switch port identifier is used to indicate a position of a connector connected in a cable backplane, and the preset list includes a corresponding relationship between each switch port identifier and each slot number.

[0132] Optionally, the second slot number can also be referred to as an analyzed slot number.

[0133] Optionally, in a specific implementation, steps S702 and S703 can be performed first, and then step S701 is performed, which is not limited here.

[0134] S704, the cabinet management board determines whether to send an alarm information according to the first slot number and the second slot number, the alarm information being used to indicate that the first slot number and the second slot number are inconsistent.

[0135] In an optional embodiment, the cabinet management board determining whether to send an alarm information according to the first slot number and the second slot number can include: determining whether the first slot number and the second slot number are consistent, if consistent, not doing any processing; and if inconsistent, determining to send the alarm information.

[0136] For example, assuming that the cabinet management board determines that the first slot number corresponding to the server node is 00 and the second slot number is 01, it can be determined that the first slot number and the second slot number are inconsistent, at this time, the cabinet management board can send the alarm information. In this way, the staff can perform relevant checks (such as checking whether the cable is inserted incorrectly, or checking whether the LLDP packet exists an analysis failure) after receiving the alarm information, so as to perform corresponding modification measures based on the check result.

[0137] In an optional embodiment, the server node can not perform step S701. In this embodiment, the cabinet management board can send the second slot number corresponding to the server node determined by the cabinet management board to the server node, so that the server node can determine whether to send an alarm information according to the first slot number and the second slot number.

[0138] It can be seen that in the embodiment of the application, the cabinet management board can determine the second slot number (or referred to as the analyzed slot number) of the server node in the server cabinet, and receive the first slot number (i.e. accurate slot information) from the server node, and determine whether to send an alarm information according to the first slot number and the second slot number, so that the staff can determine whether it is necessary to troubleshoot the cable connection failure (such as cable misinsertion) or LLDP packet analysis failure according to whether the alarm information is received, and eliminate the corresponding failure through relevant operations after receiving the alarm information.
