Any embodiment or design described herein as "exemplary" or "for example" should not be construed as preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete fashion.

In the description of the embodiments of the present application, unless otherwise indicated, the meaning of "a plurality" means two or more. For example, a plurality of processors refers to two or more processors; the plurality of transit connectors refers to two or more transit connectors.

Firstly, explanation is made on some concepts related in a method for detecting misplug of an external device and a computing device provided by the embodiment of the application, which are specifically as follows:

pin: called Pin, english called Pin. The wiring to the peripheral circuits is led out from the internal circuit of the integrated circuit (chip), and all the pins form the interface of the chip. A section of the end of the lead is soldered to a pad on the printed board.

Multiple hosts: also called multi-host, for indicating a scenario in which one device (e.g., a network card) is simultaneously connected to multiple processors or devices.

Based on the foregoing background, embodiments of the present application provide a computing device, where a controller in the computing device is connected to a plurality of transit connectors in the computing device; the transit connector is connected with an expansion connector in the docking station. The controller is used for determining the current connection relation of the docking station, and the connection relation comprises the following steps: a connection relationship of each docking connector in the docking station with the transit connector; and outputting alarm information for indicating that the current connection relation of the docking station is wrong under the condition that the current connection relation of the docking station is different from the preset connection relation of the docking station. Therefore, the user can timely acquire the error of the current connection relation of the docking station and correct the error connection relation, and the correct connection of the cable between the docking station and the transfer connector is ensured, so that the problem that the server cannot normally use the hardware resources to be expanded is solved.

Embodiments of the present application provide a computing device comprising: the docking station comprises a controller, a plurality of transfer connectors and at least two docking stations, wherein each docking station comprises at least two docking connectors. For example: the computing device includes: 1 controller, 4 transit connectors, and 2 docking stations, wherein each docking station includes 2 docking connectors. For ease of description of the embodiments herein, the computing device is illustrated in fig. 1, where the number of controllers in the computing device is 1, the number of docking connectors is 4, the number of docking stations is 2, and the number of docking connectors in each docking station is 2.

The 4 transfer connectors are respectively connected with the controller, namely: the transfer connector_1, the transfer connector_2, the transfer connector_3 and the transfer connector_4 are respectively connected with the controller; the controller may be at least one of a baseboard management controller (baseboard management controller, BMC), a programmable logic device (complex programmable logic device, CPLD), an FPGA, a DSP, and the like having processing capability.

One of the 4 transfer connectors is connected with one of the 2 docking stations (e.g., transfer connector_1 is connected with expansion connector_1, transfer connector_2 is connected with expansion connector_2, transfer connector_3 is connected with expansion connector_3, and transfer connector_4 is connected with expansion connector_4).

It should be noted that, in the embodiment of the present application, any two devices in the computing device are electrically connected (i.e. connected by a cable), which is not described in detail later.

The docking station is a device for providing a slot for a device to be expanded of the computing device, and can be understood as a circuit board with a connection slot. For example: when the equipment to be expanded is a network card, the docking station is a riser card for providing a network card slot; when the device to be expanded is a hard disk, the docking station is a hard disk backboard provided with a hard disk slot.

It should be understood that only one type of device to be expanded can be inserted into one expansion dock, and the expansion docks corresponding to different types of devices to be expanded are different, for example, the expansion dock corresponding to an OCP (open compute project, open computing item) network card is different from the expansion dock corresponding to a DPU (data processing unit, data processing) network card, and the expansion dock corresponding to a solid state disk is also different from the expansion dock corresponding to a mechanical disk.

It should be noted that, the types of the transit connector and the expansion connector are the same, for example: when the transit connector is a unified bus connector (unified bus connector, UBC) connector, the expansion connector is also a UBC connector; when the transit connector is an slimline_x8 connector, the extension connector is also an slimline_x8 connector, and in this embodiment, the transit connector and the extension connector are UBC connectors, which will not be described in detail later.

The controller is used for determining the current connection relation of the docking stations (namely, docking station_1 and docking station_2); the current connection relation of the docking station comprises the following steps: a connection relationship of each expansion connector in the docking station with the transit connector; that is, the current connection relationship of the docking station is used to indicate which of the transit connectors the docking connector in the docking station is actually connected to. For example: as shown in fig. 1, the current connection relationship of the docking station_1 includes: connection of expansion connector_1 to transit connector_1 and connection of expansion connector_2 to transit connector_2.

It should be noted that, the positions of the transit connectors_1 to transit connector_4 in the computing device are fixed; and which pin on the controller is connected to one of the transit connectors is also fixed, the controller has determined (or has knowledge of) the transit connector to which each pin on it is connected.

On the basis that the controller has knowledge of the transit connectors to which each pin is connected, the specific implementation of the controller determining the current connection relationship of a docking station includes: the controller obtains the identifiers of a plurality of expansion connectors (such as that the transit connector_1 is connected with the expansion connector_1) connected with each transit connector through each transit connector (such as that the transit connector_1 is connected with the expansion connector_1), wherein the identifiers of the expansion connectors are used for indicating the expansion dock where the expansion connectors are positioned and the positions of the expansion connectors on the expansion dock, and further, the controller can judge which expansion connector on which expansion dock each transit connector is connected with through the identifiers of the plurality of expansion connectors; the controller then determines the current connection relationship of the docking connector on the docking station with each transit connector based on the identification of the plurality of docking connectors.

Illustratively, assume that as shown in FIG. 1, a transit connector_1 in a computing device is connected to an expansion connector_1, a transit connector_2 is connected to an expansion connector_2, a transit connector_3 is connected to an expansion connector_3, and a transit connector_4 is connected to an expansion connector_4; since the docking station_1 includes: expansion connector_1 and expansion connector_2; the current connection relationship of the docking station_1 includes: the transit connector_1 is connected with the expansion connector_1, and the transit connector_2 is connected with the expansion connector_2. Since docking station_2 includes docking connector_3 and docking connector_4 therein; the current connection relationship of docking station_2 includes: the transit connector_3 is connected with the expansion connector_3, and the transit connector_4 is connected with the expansion connector_4.

Optionally, in one implementation, the identification of the expansion connector in the computing device shown in fig. 1 includes: a first location identifier and a second location identifier, the expansion connector comprising: a first pin and a second pin; the first pin is configured with a first position identifier, and the first position identifier is used for indicating position information of the expansion connector in a target docking station, wherein the target docking station is the docking station where the expansion connector is located. The second pin is configured with a second location identifier for indicating location information of the target docking station in the at least two docking stations; that is, the first location identifier is a location identifier of the docking connector in the target docking station, and the second location identifier is a location identifier of the target docking station in the plurality of docking stations; the controller may then determine a target docking station from among the plurality of docking stations in the computing device based on the second location identification, and then determine the expansion connector from among the plurality of expansion connectors in the target docking station based on the first location identification, so the controller may determine a specific location of the expansion connector based on the first location identification and the second location identification.

Illustratively, assume that the expansion connector is expansion connector_1 in fig. 1, where expansion connector_1 includes: a first pin and a second pin; the first pin is configured with a first position identifier "0", where the first position identifier "0" is used to indicate that the expansion connector_1 is located at a left side position in the docking station where the expansion connector_1 is located. A second position identifier '0' is configured on the second pin, wherein the second position identifier '0' is used for indicating that the docking station where the expansion connector_1 is located is the docking station which is located at the left side position in the docking station_1 and the docking station_2, and the docking station where the expansion connector_1 is located is the docking station_1 because the docking station_1 is located at the left side of the docking station_2; also, since the expansion connector_1 is located at the left position in the expansion dock_1, it is determined that the expansion connector is the expansion connector_1 in the expansion dock_1.

Based on the first pin and the second pin on the expansion connector, the controller obtains the identifier of the expansion connector (such as the identifier of the expansion connector_1) connected with the controller through a transfer connector (such as the transfer connector_1), wherein the identifier of the expansion connector_1 comprises: a first location identifier and a second location identifier of the expansion connector_1; and then, the controller determines the connection relation between the expansion connectors with the same second position identification in the acquired plurality of expansion connector identifications and the transfer connector as the connection relation of the docking station indicated by the second position identification.

Illustratively, assuming that one of the docking stations is located at a left position within the docking station, the first position of that docking connector is identified as "0", and that one of the docking stations is located at a right position within the docking station, the first position of that docking connector is identified as "1"; the second position of the docking connector in one docking station is identified as "0" when the docking station is in a left position within the computing device and as "1" when the docking station is in a right position within the computing device.

Then in the computing device shown in fig. 1, the identity of the expansion connector acquired by the controller through transit connector_1 is { identity of expansion connector_1: (0, 0) }; wherein, the first "0" in (0, 0) is the position identification of the expansion connector_1 in the docking station where it is located (i.e. docking station_1), i.e. the first "0" is the first position identification of the expansion connector_1; the second "0" is the location identification of docking station_1, i.e., the second "0" is the second location identification of docking station_1. The identity of the expansion connector acquired by the controller through the transit connector_2 is { identity of expansion connector_2: (1, 0) }; the identity of the expansion connector acquired by the controller through the transit connector_3 is { identity of expansion connector_3: (0, 1) }; the identity of the expansion connector acquired by the controller through the transit connector_4 is { identity of expansion connector_4: (1,1) }. The controller obtains the identifier (0, 0) of the transit connector_1 through the transit connector_1, which indicates that the transit connector_1 is connected with the expansion connector_1 in the docking station_1, that is, the controller obtains the identifier of which expansion connector through the transit connector_1, which indicates that the transit connector_1 is connected with the expansion connector.

Since the second position identification in the identification (0, 0) of the expansion connector_1 acquired by the transit connector_1 and the second position identification in the identification (1, 0) of the expansion connector_2 acquired by the transit connector_2 are both "0", and the first position identification in the identification (0, 0) of the expansion connector_1 is "0", the first position identification in the identification (1, 0) of the expansion connector_2 is "1", the controller determines that the connection relationship of the current expansion connector_1 is that the expansion connector_1 is connected with the transit connector_1 and the transit connector_2, and can further confirm that the expansion connector_1 on the expansion connector_1 is connected with the transit connector_1, and the expansion connector_2 on the expansion connector_2 is connected with the transit connector_2, based on the identifications { (0, 0) and (1, 0) }, of the expansion connector_1 transmitted thereto, respectively. In the same manner, the controller determines that the current connection relationship of docking station_2 is that docking station_2 is connected with transit connector_3 and transit connector_4, and may further confirm that docking connector_3 on docking station_2 is connected with transit connector_3 and docking connector_4 on docking station_2 is connected with transit connector_4.

The controller is further configured to output alarm information when the current connection relationship of the docking station is different from the preset connection relationship of the docking station, where the alarm information is used to indicate that the current connection relationship of the docking station is wrong.

It should be noted that, the preset connection relationship of the docking station may be obtained by the controller from a local location, or may be obtained by the controller from another device or equipment.

For example, assuming that the current connection relationship of the docking station_1 is shown in fig. 1, the current connection relationship of the docking station_1 is in a single-host mode, and specifically, the current connection relationship of the docking station_1 includes: the extension connector_1 is connected with the transit connector_1, and the extension connector_2 is connected with the transit connector_2. Assume that the preset connection relationship of the docking station_1 is a multi-host mode, as shown in fig. 2, specifically including: expansion connector_1 is connected to transit connector_1, and expansion connector_2 is connected to transit connector_4. Since the expansion connector_2 is connected with the transit connector_4 in the preset connection relation of the expansion dock_1, if the expansion connector_2 is connected with the transit connector_2 in the current connection relation of the expansion dock_1; then the current connection relationship of the docking station_1 is different from the preset connection relationship of the docking station_1, at this time, the controller outputs alarm information, the content of the alarm information is that the current connection relationship of the docking station_1 is wrong, and the staff is requested to correct the following in time! The following is carried out The following is carried out ".

Optionally, the identifier of the expansion connector further includes a type identifier of a target docking station where the expansion connector is located, where the expansion connector includes: in the case of the first pin and the second pin, the expansion connector further includes: a third pin; the third pin configures a type identification of the target docking station.

The docking station comprises at least: a first type and a second type, wherein the first type of docking station is a docking station for providing slots to a hard disk, and the second type of docking station is a docking station for providing slots to a network card.

Based on the first pin, the second pin and the third pin on the expansion connector, the controller obtains the identifier of the expansion connector_1 connected with the controller through a transfer connector (such as a transfer connector_1), wherein the identifier of the expansion connector_1: comprising the following steps: a first location identifier, a second location identifier of the expansion connector_1, and a type identifier of the expansion dock_1 where the expansion connector_1 is located; then, the controller determines the connection relationship between the docking connector, of which the second position identifier and the docking station type identifier are the same, and the transit connector as the connection relationship of the docking station_1.

Illustratively, the connection relationship between the transit connectors_1 to_4 and the expansion connectors is shown in fig. 1, the transit connector_1 is connected with the expansion connector_1 in the expansion dock_1, the transit connector_2 is connected with the expansion connector_2 in the expansion dock_1, the transit connector_3 is connected with the expansion connector_3 in the expansion dock_2, and the transit connector_4 is connected with the expansion connector_4 in the expansion dock_2; wherein the first position of expansion connector_1 is identified as "0" (i.e., on the left side) and the first position of expansion connector_2 is identified as "1" (i.e., on the right side); the location of docking station_1 is identified as "0", then the second location of docking connector_1 and docking connector_2 are both identified as "0"; the docking station_1 type is identified as "0"; this type identifier of "0" indicates that the docking station_1 is a docking station for providing a slot for the network card; the first position of expansion connector_3 is identified as "0", and the first position of expansion connector_4 is identified as "1"; the position of docking station_2 is identified as "1", and then the second positions of docking connector_3 and docking connector_4 are identified as "1"; the docking station_2 type is identified as "1"; the type identifier "1" indicates that the docking station_2 is a docking station for providing a slot to a hard disk (e.g., NVME).

Then, at this time, the identifier obtained by the controller through the transit connector_1 is { the identifier of the expansion connector_1: (0, 0) }, wherein the first "0" of the identifications (0, 0) of the expansion connector_1 is the first location identification of the expansion connector_1, the second "0" is the second location identification of the expansion connector_1, and the third "0" is the type identification of the expansion dock_1 where the expansion connector_1 is located. The identity obtained by the controller through the transit connector_2 is the identity of { expansion connector_2: (1, 0) }; the identity obtained by the controller through the transit connector_3 is the identity of { expansion connector_3: (0, 1) }; the identity obtained by the controller through the transit connector_4 is the identity of { expansion connector_4: (1,1,1) }.

Since the identifier (0, 0) of the expansion connector_1 acquired by the transit connector_1 and the second position identifier in the identifier (1, 0) of the expansion connector_2 acquired by the transit connector_2 are both "0", and the type identifiers of the docking stations are both 0; and the first position in the identifier (0, 0) of the expansion connector_1 is identified as "0", and the first position in the identifier (1, 0) of the expansion connector_2 is identified as "1", so the controller determines that the connection relationship of the current docking station_1 is that the docking station_1 is connected with the transit connector_1 and the transit connector_2; and it can be further confirmed that the docking connector_1 on the docking station_1 is connected with the transit connector_1, the docking connector_2 on the docking station_2 is connected with the transit connector_2, and the type of the docking station_1 is a network card.

The identifier of the expansion connector is used for indicating the expansion connector connected with the transit connector, that is, when the controller obtains the identifier of the expansion connector_1 through the transit connector_1, the controller indicates that the transit connector_1 is connected with the expansion connector_1; the identifier of the expansion connector includes pin information of the expansion connector, the pin information is used for determining whether the expansion connector actually connected with the transfer connector is a preset expansion connector, so as to judge whether the cable between the transfer connector and the expansion connector is connected correctly, for example, assume that the expansion connector indicated by the pin information acquired by the controller through the transfer connector_1 is an expansion connector_2; then, assume that the preset transfer connector_1 is connected with the expansion connector_1; then the controller determines at this point that transit connector_1 is connected to the wrong expansion connector.

It should be understood that the controller is respectively connected with a plurality of transfer connectors in the computing device where the controller is located, wherein the plurality of transfer connectors are respectively connected with different expansion connectors in a one-to-one manner; based on this, the controller acquires the identification of the expansion connector connected to each of the transit connectors through the plurality of transit connectors, respectively.

Illustratively, in the case where the transit connector_1 is connected to the expansion connector_1 in the computing device as shown in fig. 1, the pin information of the expansion connector_1 is included in the identification of the expansion connector acquired by the controller through the transit connector_1.

In one implementation, the identification of the expansion connector includes: a first location identifier and a second location identifier of the expansion connector; the first position identifier is used for indicating position information of the expansion connector in a target expansion dock, wherein the target expansion dock is the expansion dock where the expansion connector is located; the second location identification is used to indicate location information of the target docking station in at least two of the computing devices.

Illustratively, assume that transit connector_1 in the computing device shown in FIG. 1 is connected to docking connector_1 in docking station_1, transit connector_2 is connected to docking connector_2 in docking station_1, transit connector_3 is connected to docking connector_3 in docking station_2, and transit connector_4 is connected to docking connector_4 in docking station_2. The first pin of the expansion connector_1 is configured with a first position identifier "0", the second pin of the expansion connector_1 is configured with a second position identifier "0", the first pin of the expansion connector_2 is configured with a first position identifier "1", and the second pin of the expansion connector_2 is configured with a second position identifier "0"; the first pin of the expansion connector_3 is provided with a first position identifier "0", the second pin of the expansion connector_3 is provided with a second position identifier "1", the first pin of the expansion connector_4 is provided with a first position identifier "1", and the second pin of the expansion connector_4 is provided with a second position identifier "1".

Then, the identifier obtained by the controller through the transit connector_1 is { identifier of the expansion connector_1, (0, 0) }, wherein the first "0" in the identifier (0, 0) of the expansion connector_1 represents the first position identifier of the expansion connector_1, and the second "0" represents the second position identifier of the expansion connector_1; the identification obtained through the transit connector_2 is the identification of { expansion connector_2, (1, 0) }, the identification obtained through the transit connector_3 is the identification of { expansion connector_3, (0, 1) }, and the identification obtained through the transit connector_4 is the identification of { expansion connector_4, (1, 1}.

In another implementation manner, the identification of the expansion connector further includes, on the basis of the first location identification and the second location identification of the expansion connector, the identification of the expansion connector: and identifying the type of the target docking station, wherein the target docking station is the docking station where the docking connector is positioned.

It should be noted that, the expansion connector includes: the expansion connector further comprises: a third pin, on which a type identifier of the target docking station is configured; the controller obtains the type identifier of the target docking station from the third pin of the expansion connector through the transfer connector, and determines the first position identifier, the second position identifier and the type identifier of the target docking station of the expansion connector as the identifiers of the expansion connector.

The types of the target docking station include: a first type and a second type; the first type of docking station is used for providing slots for the hard disk, and the second type of docking station is used for providing slots for the network card; alternatively, the first type of docking station is an NVME backplane for providing slot riser cards to the OCP network card and the second type of docking station is an NVME backplane for providing slots to the NVME.

Illustratively, assuming that one of the docking stations is located at a left position within the docking station, the first position of that docking connector is identified as "0", and that one of the docking stations is located at a right position within the docking station, the first position of that docking connector is identified as "1"; the second position of the docking connector in one docking station is identified as "0" when the docking station is in a left position within the computing device and as "1" when the docking station is in a right position within the computing device; when the type of one docking station is the first type, the type of the docking station is identified as '0', and when the type of one docking station is the second type, the type of the docking station is identified as '1'. Assume again that the type of docking station_1 in the computing device shown in fig. 1 is identified as "0" and the type of docking station_2 is identified as "1".

Then, as shown in fig. 1, in the case where the transit connector in the computing device is connected to the expansion connector through a cable shown by a broken line, the controller in the computing device obtains an identification of { expansion connector_1: (0, 0) }, wherein the first "0" in (0, 0) is the first location identifier of expansion connector_1, the second "0" is the second location identifier of expansion connector_1, and the third "0" is the type identifier of expansion dock_1 where expansion connector_1 is located. The identity obtained by transit connector_2 is the identity of { expansion connector_2: (1, 0) }, the identification obtained by the transit connector_3 is the identification of { expansion connector_3: (0, 1) }, the identification obtained by transit connector_4 is the identification of { expansion connector_4: (1,1,1) }.

S110b, the controller determines the current connection relation of the docking station according to the obtained identifiers of the plurality of docking connectors.

In the case that the identifier of the expansion connector includes the first location identifier and the second location identifier of the expansion connector, the specific implementation of S110b includes: and the controller determines the connection relation between all the expansion connectors with the same second position identification in the obtained multiple expansion connector identifications and the transfer connector as the current connection relation of the docking station.

The current connection relationship of the docking station comprises the connection relationship of all docking connectors on the docking station and the transfer connector.

Illustratively, as shown in fig. 1, in a case where the transit connector in the computing device is connected to the expansion connector through a cable represented by a broken line, the identification of the plurality of expansion connectors acquired by the controller includes: { identification of expansion connector_1 (0, 0) } wherein the first "0" in the identification of expansion connector_1 (0, 0) represents the first location identification of expansion connector_1 and the second "0" represents the second location identification of expansion connector_1; { identification of expansion connector_2, (1, 0) }, { identification of expansion connector_3, (0, 1) }, and { identification of expansion connector_4, (1, 1) }. Since the identifier (0, 0) of the expansion connector_1 is obtained by the controller through the transfer connector_1, it is determined that the transfer connector_1 is connected with the expansion connector_1, the transfer connector_2 is connected with the expansion connector_2, the transfer connector_3 is connected with the expansion connector_3, and the transfer connector_4 is connected with the expansion connector_4 in the same manner; because the second position identifiers in the identifiers (0, 0) and (1, 0) respectively acquired by the controller through the transfer connector_1 and the transfer connector_2 are both "0", and the position identifier of the docking station_1 is also "0", the controller determines that the current connection relationship of the docking station_1 comprises: the transit connector_1 is connected with the expansion connector_1, and the transit connector_2 is connected with the expansion connector_2. Likewise, the controller determines that the current connection relationship of docking station_2 includes: the transit connector_3 is connected with the expansion connector_3, and the transit connector_4 is connected with the expansion connector_4.

In the case that the identifier of the expansion connector includes a first location identifier, a second location identifier of the expansion connector, and a type identifier of a target docking station where the expansion connector is located, the specific implementation of S110b includes: the controller determines the connection relation between the expansion connector and the transfer connector, wherein the second position identification and the type identification of the expansion connector are the same, in the identifications of the expansion connectors, as the current connection relation of the expansion dock.

Illustratively, as shown in fig. 1, in a case where the transit connector in the computing device is connected to the expansion connector through a cable represented by a broken line, the identification of the plurality of expansion connectors acquired by the controller in the computing device includes: identification of { extended connector_1: (0, 0) }, wherein the first "0" in (0, 0) is a first location identifier of expansion connector_1, the second "0" is a second location identifier of expansion connector_1, and the third "0" is a type identifier of expansion dock_1 in which expansion connector_1 is located; identification of { extended connector_2: (1, 0) }, { identification of expansion connector_3: (0, 1) } identity of { expansion connector_4: (1,1,1) }.

Since the identifier acquired by the controller through the transit connector_1 is the identifier (0, 0) of the expansion connector_1, it is determined that the transit connector_1 is connected with the expansion connector_1, and the transit connector_2 is connected with the expansion connector_2, the transit connector_3 is connected with the expansion connector_3, and the transit connector_4 is connected with the expansion connector_4 in the same manner; because the second position identifiers in the identifiers (0, 0) and (1, 0) acquired by the transfer connector_1 and the transfer connector_2 are both 0, and the third position identifiers are both 0; while the second position of docking station_1 is identified as "0", and the type identification of docking station_1 is also "0"; the controller determines that the current connection relationship of docking station_1 includes: the transfer connector_1 is connected with the expansion connector_1, the transfer connector_2 is connected with the expansion connector_2, and the type of the expansion dock_1 is a network card. Likewise, the controller determines that the current connection relationship of docking station_2 includes: the transit connector_3 is connected with the expansion connector_3, and the transit connector_4 is connected with the expansion connector_4.

S120, the controller determines whether the current connection relation of the docking station is the same as the preset connection relation of the docking station.

It should be noted that, the preset connection relationship of the docking station may be directly obtained by the controller from the local, or may be obtained by the controller from another device in the computing device, or may be obtained by the controller from another device.

For example, it is assumed that the transit connector_1 is connected to the expansion connector_1 in a preset connection relationship of the expansion connector_1, that is, the identifier obtained by the controller through the transit connector_1 is (0, 0), where (0, 0) is the identifier of the expansion connector_1, the first "0" in (0, 0) is the first location identifier of the expansion connector_1, the second "0" is the second location identifier of the expansion connector_1, and the third "0" is the type identifier of the expansion connector_1 where the expansion connector_1 is located.

Then, when the transit connector_1 is connected with the docking connector_1 in the current connection relationship of the docking station_1, that is, the identifier of the docking connector actually acquired by the controller through the transit connector_1 is (0, 0), the controller determines that the current connection relationship of the docking station_1 is the same as the preset connection relationship of the docking station_1.

In the case of a cable connection error between the transit connector and the expansion connector, for example, the transit connector_1 is connected with the expansion connector_2, the identification of the expansion connector acquired by the controller through the transit connector_1 is (1, 0), since the identification (1, 0) of the expansion connector currently acquired through the transit connector_1 is not identical to the identification (0, 0) of the expansion connector preset acquired through the transit connector_1; the controller determines that the current connection relationship of the docking station_1 is different from the preset connection relationship of the docking station_1.

In case the cable connection between the transit connector and the docking connector is correct, and the type of docking station connected is wrong, such as: when the identifier of the expansion connector acquired by the controller through the transfer connector_1 is (0, 1), the docking station represented by the type identifier "1" of the docking station_1 in the identifier of the expansion connector currently acquired by the transfer connector_1 is an NVME backboard, the third bit of the identifier of the expansion connector preset in the controller and acquired by the transfer connector_1 is "0", and the docking station represented by "0" is a riser card; the NVME backplate and the riser card are docking stations providing different types of slots, so the controller determines that the current connection relationship of docking station_1 is different from the preset connection relationship of docking station_1.

And under the condition that the current connection relation of the docking station is the same as the preset connection relation of the docking station, the controller executes an ending action to end the current method.

In case that the current connection relationship of the docking station is different from the preset connection relationship of the docking station, the controller performs S130 described below.

S130, the controller outputs alarm information.

The alarm information is used for indicating the current connection relation error of the docking station.

Illustratively, as shown in fig. 1, in the case that the transit connector in the computing device is connected to the expansion connector by a cable represented by a dotted line, the current connection relationship of the docking station_1 is in a single-host mode, and specifically, the current connection relationship of the docking station_1 includes: the extension connector_1 is connected with the transfer connector_1, and the extension connector_2 is connected with the transfer connector_2; assume further that the preset connection relationship of the docking station_1 is a multi-host mode as shown in fig. 2, which specifically includes: the extension connector_1 is connected with the transfer connector_1, and the extension connector_2 is connected with the transfer connector_4; since the expansion connector_2 is connected with the transit connector_4 in the preset connection relation of the expansion dock_1, and the expansion connector_2 is connected with the transit connector_2 in the current connection relation of the expansion dock_1; therefore, the current connection relation of the docking station_1 is different from the preset connection relation of the docking station_1, at the moment, the controller outputs alarm information, and the content of the alarm information is that the current connection relation of the docking station_1 is wrong, and the staff is required to correct the following conditions in time! The following is carried out The following is carried out ".
