The embodiment provides a device slot identification method, which can be applied to electronic devices such as a server and terminal equipment. The electronic equipment can be used for installing the expansion equipment required by a user through the expansion slot, and the installed expansion equipment can be mounted on an expansion port of the electronic equipment. The positions of the expansion devices need to be known during maintenance and assembly of the electronic devices, so that the identification of the device slots of the server is needed. The expansion port may be a PCIe (PERIPHERAL COMPONENT INTERCONNECT EXPRESS ) port. Correspondingly, the expansion slot may be a PCIe slot (PCIe expansion slot), and the expansion device mounted through the PCIe slot may be a PCIe expansion device (for example, a network card or the like may be referred to as a PCIe peripheral), and for other types of expansion ports, expansion slots, and expansion devices, the device slot identification method in this embodiment is also applicable. The expansion port may be an expansion port of a processing unit of the electronic device, for example, an expansion port of a CPU (Central Processing Unit ), or an expansion port of another processing unit (for example, a micro control unit), which is not limited in this embodiment.

With the development of the internet industry and the large-scale application of cloud computing and big data technology, the demand of servers is greatly increased. The scalability of a server is an important technical index of the server. The extensible peripherals of the current server mainly comprise a hard disk and PCIe devices. Wherein various expansion cards conforming to the PCIe standard add a variety of features to the server. Typically, the server will have many PCIe slots for installing PCIe expansion devices required by the user. The identification of PCIe device slots is an important requirement in server operation and maintenance and reconfiguration (configuration modification) of the server because the locations where these PCIe devices are located need to be known.

For example, as shown in fig. 2, a server has 6 PCIe slots, that is, PCIe1 to PCIe6 (that is, PCIe slots 1 to PCIe slots 6), and 6 PCIe standard network cards may be installed. When a certain network card fails, the network card needs to be known to be installed on which PCIe slot position so as to be convenient for operation and maintenance personnel to maintain and replace. Thus, there is a need for a management system of a server that can identify the PCIe slots on the server to which each PCIe expansion device is installed.

In the related art, in order to perform device slot identification, a fixed topology structure may be adopted, that is, the expansion ports of the electronic device are in one-to-one correspondence with the expansion slots on the device chassis, and all configurations of the electronic device use the correspondence. However, in the above device slot identification manner, all configurations of the electronic device need to be used according to a given topology, which limits flexibility of device use.

Taking a server as an example, in the design of the server, a fixed PCIe topology may be adopted, that is, PCIe ports of a CPU on a motherboard of the server and PCIe slots on a chassis of the server are in one-to-one correspondence, and all configurations of the server use this correspondence. As shown in fig. 3, there are two CPUs on the motherboard, each with 3 x16 bandwidth PCIe ports (ports). In the server design, the PCIe ports of the CPU are fixed to PCIe slots on the chassis one by wires, connectors or cables on the PCB (Printed Circuit Board ), i.e., in all configurations, PCIe peripherals are plugged into PCIe slots 1, and the device is connected to PCIe port 1 of CPU 0. Through the fixed mapping relationship, the management system can know which PCIe slot the PCIe expansion device is installed on.

However, although PCIe slot identification can be implemented by the above solution, flexibility of server use is limited, all configurations need to be used according to a given PCIe topology, and obvious disadvantages exist in a multi-purpose requirement environment of the server.

In order to solve the above problem, an FRU (Field Replaceable Unit ) unit may be added to the riser card extending the slot, and slot information in which the corresponding riser card is installed is stored in the FRU. And designing a corresponding number of transfer cards according to the number of the expansion slots. Therefore, the expansion port of the processing component on the main board can be connected to any adapter card (equivalent to being connected to the corresponding expansion slot) through the cable, and the expansion slot can be known by acquiring the slot information stored by the FRU, so that the expansion device is known to be mounted on which expansion slot.

For example, an FRU unit may be added to a Riser (an example of a Riser card) card, where slot information of PCIe slots in which a corresponding Riser card is installed is stored, and how many Riser cards are designed with how many PCIe slots. Therefore, the PCIe port of the CPU on the main board can be connected to any Riser card (namely to any PCIe slot) through a cable, and the control system can know which expansion slot the Riser card is mounted on by acquiring FRU information, so that the PCIe expansion device is hung on which expansion slot. Here, the Riser card is a PCB adapter board, fixed on a PCIe slot bracket, and PCIe peripherals are installed on the Riser card.

The scheme is flexible in topology, can meet the requirements of various configurations of the server, but needs to design various adapter cards (for example, riser cards), and is easy to produce material stagnation, so that the production and maintenance cost of the electronic equipment is increased.

In order to at least partially solve the above-mentioned problem, in this embodiment, a manner that a metal copper exposure area is set on an adapter card installed on an expansion slot and a positioning contact group is set on a structural support, and positions of positioning contacts contacted by the metal copper exposure area of the adapter card installed on different expansion slots in the positioning contact group are at least partially different is adopted, the adapter card may generate slot indication information based on positions of positioning contacts contacted by the metal copper exposure area in the positioning contact group, and the generated slot indication information may indicate the expansion slot (the slot position of the expansion slot) installed therein; when the expansion port is loaded with expansion equipment, the expansion slot position where the associated adapter card is installed can be determined through the slot position indication information stored in the adapter card associated with the mounted expansion equipment, so that equipment slot position identification is realized. The equipment slot position identification mode does not need to fix the connection relation between the expansion port and the expansion slot position, does not need to design various adapter cards, can increase the flexibility of equipment use, is convenient to carry out equipment maintenance, and has small influence on production and maintenance cost.

The device slot position identification method in the embodiment can be applied to electronic devices, the electronic devices comprise a processing component and a structural support, the processing component comprises a plurality of expansion ports, the structural support is provided with a plurality of expansion slots, and adapter cards are arranged on the expansion slots in the expansion slots, namely, the corresponding relations among the expansion ports, the expansion slots and the adapter cards can be one-to-one correspondence. For each expansion port, the expansion port can be used for connecting the mounted expansion equipment through the transfer card mounted on the corresponding expansion slot, and the corresponding relationship among the expansion port, the expansion slot, the transfer card and the expansion setting can be one-to-one correspondence.

The structural support is used for fixing the adapter card and the expansion equipment, can provide position information besides the supporting function, and the provided position information can be slot position indication information which can be used for indicating the slot position of the expansion slot position where the adapter card corresponding to the identification is installed. For this purpose, a plurality of first positioning contact groups may be provided on the structural support, each of the expansion slots may correspond to one of the first positioning contact groups, and expansion slots among the plurality of expansion slots may have a one-to-one correspondence with the first positioning contact groups among the plurality of first positioning contact groups. The positions of the metal copper exposure areas of the adapter cards installed on different expansion slots in the expansion slots are at least partially different from the positions of the positioning contacts contacted by the corresponding first positioning contact sets in the corresponding first positioning contact sets. Here, the structural support may be fixed to the chassis of the electronic device, and thus, the expansion slot on the structural support may also be understood as an expansion slot on the chassis.

Alternatively, the Riser card may be a Riser card (i.e., PCIe Riser card, PCIe add-on card) that may convert PCIe signals on the motherboard to their corresponding PCIe slots. When a golden finger (referring to a row of contacts on a PCIe peripheral device) on a PCIe peripheral device (i.e., a PCIe expansion device) is inserted on the PCIe slot of the Riser card, PCIe signals on the motherboard may be connected to the PCIe peripheral device. PCIe peripheral equipment, the Riser card and the structural support are assembled and fixed on the case for use. As shown in fig. 4, fig. 4 illustrates an exemplary positional relationship among PCIe peripherals, fabric supports, and chassis. Here, the PCIe slots are locations on the fabric support where PCIe expansion devices may be installed. The structural support can be made of metal, and PCIe peripheral equipment and a Riser card are fixed on the chassis through screws or bayonets.

Alternatively, the number of point contacts included in each first positioning contact set may be the same, for example, as shown in fig. 5, where M Riser cards are allowed to be installed on the side wall of the structural support, each Riser card corresponds to one first positioning contact set, each first positioning contact set includes N positioning contacts, and each first positioning contact set allows positioning contacts (positioning contacts marked gray in fig. 5) contacted by metal copper exposure areas of the corresponding adapter card to be at least partially different in positions in the first positioning contact set. Here, the contact of the metal copper-exposed region with the positioning contact may be achieved by forming a via with the positioning contact. Correspondingly, the positioning contact which is not allowed to be contacted with the metal copper exposure area of the corresponding adapter card can be omitted. In this case, the number of positioning contacts included in the different first positioning contact sets may be different as long as the corresponding adapter card can be made to recognize different slot indication information.

Fig. 6 is a schematic flow chart of an alternative device slot identification method according to an embodiment of the present application, as shown in fig. 6, the flow includes the following steps S602 to S604.

Step S602, when there is a mounted expansion port of the mounted expansion device in the plurality of expansion ports, slot indication information stored in a designated register of the associated adapter card is obtained, and target slot indication information is obtained.

In this embodiment, when there is an identification requirement, an expansion port on which an expansion device is mounted in a plurality of expansion ports may be detected, and if an expansion port on which an expansion device is mounted is detected, that is, an expansion port on which an expansion device is mounted, slot indication information stored in a designated register of an associated switch card may be obtained, so as to obtain target slot indication information. Here, the associated patch card is a patch card that connects the mounted expansion port and the expansion device mounted on the mounted expansion port, and the expansion slot in which the associated patch card is mounted may be an associated expansion slot. The mounted expansion port and the associated transit card may be connected by a communication bus, through which the slot indication information stored in the associated transit card, i.e., the target slot indication information, may be obtained from a designated register of the associated transit card.

The target slot position indication information is generated based on the positions of the positioning contacts contacted with the metal copper exposure areas of the associated adapter cards in the first positioning contact groups, and the generated slot position indication information can be distinguished because the positions of the positioning contacts contacted with the metal copper exposure areas of different adapter cards in the first positioning contact groups are at least partially different, so that the slot position positions of the expansion slots where the corresponding associated cards are installed can be identified through the slot position indication information. For the target slot indication information, it may be used to identify the slot position of the associated extended slot. Alternatively, the above specified register may be an IO (Input/Output) Expander register, or may be another specified register, as long as the above slot indication information can be stored.

Step S604, determining an expansion slot position in which the associated adapter card is installed in the expansion slots by analyzing the target slot position indication information.

After the target slot indication information is acquired, the acquired target slot indication information may be parsed, where the parsing may be based on a correspondence between the slot indication information and a slot position of the extended slot. For example, for extended slots arranged in a matrix, part of the indication information indicates row information of the extended slots, and part of the indication information indicates column information of the extended slots. Through the analysis process, the expansion slot positions where the associated adapter cards are installed in the expansion slots, namely the slot positions of the associated expansion slots, can be determined.

It should be noted that, in order to realize automatic identification of an extended slot (e.g., PCIe slot), in this embodiment, slot information (i.e., slot indication information) is obtained through a chassis structure and a hardware circuit, and a slot position where an extended device (e.g., PCIe peripheral) is located is deduced through an identification system (a system running the device slot identification method in this embodiment, which may be referred to as a slot identification system), so as to realize automatic identification of an extended slot by an electronic device (e.g., automatic identification of a PCIe slot by a server), which increases flexibility of use of the device, facilitates operation and maintenance of a user, and is low in cost.

Under the condition that mounted expansion ports of mounted expansion equipment exist in a plurality of expansion ports, slot indication information stored in a designated register of an associated adapter card is obtained to obtain target slot indication information, wherein the associated adapter card is an adapter card for connecting the mounted expansion ports and the expansion equipment mounted on the mounted expansion ports, the target slot indication information is generated based on the position of a positioning contact contacted with a metal copper exposure area of the associated adapter card in a first positioning contact group, and the target slot indication information is used for identifying the slot position of the expansion slot where the associated adapter card is mounted; by analyzing the target slot indication information, the expansion slots in which the associated adapter cards are arranged in the expansion slots are determined, the problem that the equipment slot identification method in the related technology has poor flexibility in equipment use is solved, and the equipment use flexibility is improved.

In some exemplary embodiments, the plurality of expansion slots are divided into a plurality of expansion slot groups, and the division of the expansion slot groups may be based on slot positions of the expansion slots. For example, the plurality of expansion slot groups may correspond to a plurality of bracket areas, and the plurality of bracket areas may be divided by dividing the structural bracket into a plurality of bracket portions, or may be divided into a plurality of expansion slot groups according to the slot positions of the expansion slots, and divided based on the slot positions of the expansion slots in each expansion slot group.

For example, as shown in fig. 2, PCIe1 to PCIe6 on the server may be divided into two expansion slot groups, where PCIe1 to PCIe3 are a group, PCIe4 to PCIe6 are a group, a location area on the structural support corresponding to PCIe1 to PCIe3 may be a support area (which may be a left support), and a location area corresponding to PCIe4 to PCIe6 may be a support area (which may be a right support).

For each first positioning contact set, it can be divided into a first sub positioning contact set for identifying the position of the corresponding expansion slot in the corresponding expansion slot group and a second sub positioning contact set for identifying the expansion slot group to which the corresponding expansion slot belongs. Accordingly, the slot indication information of one extended slot may be determined based on the position of the positioning contact allowed to contact the metal copper exposure area in the corresponding first sub-positioning contact set in the first sub-positioning contact set to which the positioning contact allowed to contact the metal copper exposure area in the corresponding second sub-positioning contact set in the second sub-positioning contact set to which the positioning contact allowed to contact the metal copper exposure area in the corresponding first sub-positioning contact set is located, and may be a positioning code, where the number of bits of the code is identical to the number of positioning contacts included in the corresponding first positioning contact set. The positioning contacts here are contacts for positioning the expansion slots, which can be realized by protruding contacts and non-protruding contacts.

Optionally, the positions of the metal copper exposure area of the adapter card installed on the expansion slot in the same expansion slot group and the positioning contact contacted by the corresponding first sub-positioning contact group in the first sub-positioning contact group are at least partially different, and the positions of the metal copper exposure area of the adapter card installed on the expansion slot in the same expansion slot group and the positioning contact contacted by the corresponding second sub-positioning contact group in the second sub-positioning contact group are the same. The positions of the metal copper exposure areas of the adapter cards arranged on the expansion slots in different expansion slot groups and the positioning contacts contacted by the corresponding second sub-positioning contact groups in the second sub-positioning contact groups are at least partially different. The extended slot may be uniquely identified by a combination of the first and second sub-set of locating contacts.

Optionally, the structural support may be fixed on a chassis of the electronic device, and the structural support is further provided with a plurality of second positioning contact sets corresponding to the plurality of expansion slot bit groups one by one, where, in the second sub positioning contact sets included in the first positioning contact set corresponding to each expansion slot bit group, a positioning contact used for contacting with a metal copper exposure area of the adapter card contacts with a chassis bottom of the chassis through a positioning contact in the second positioning contact set corresponding to each expansion slot bit group. The chassis and the internal support of the electronic equipment are both made of metal, and the electronic equipment is connected with the ground after being put on the support. The circuit in the circuit board inside the chassis is equivalent to grounding after being contacted with the chassis or the metal structural part, through the design, the positioning contacts used for being contacted with the metal copper exposure area of the adapter card are grounded through the positioning contacts (hereinafter referred to as effective positioning contacts) in the second positioning contact set corresponding to each expansion slot group (can be understood as a bracket area), so that the level of the contact position of the metal copper exposure area of the adapter card and the effective positioning contacts is different from the level of other positions, and the convenience of identifying the slot indication information is improved.

For example, the structural support plays a role of fixing and supporting, the Riser card is fixed on the side wall of the structural support, and the structural support is fixed on the chassis. For the structural support, when the Riser card is arranged on the side wall of the support, the metal reed or the contact point is in contact with the Riser card on the side wall of the support, the metal reed or the contact point is also in contact with the bottom of the case at the lower end of the side wall of the support, and the metal reed or the contact point on the support is used for providing position information.

As shown in fig. 7, the server has 6 PCIe slots, which are divided into left and right groups (3 PCIe slots per group) and distributed on left and right brackets (corresponding to the bracket areas described above). If the server system recognizes that there is a PCIe device plugged in, it needs to determine which slot in 1-6 the PCIe device is installed in. For this purpose, the column and row positioning of the expansion slot can be determined first, i.e. it is known at which position (column positioning) of the expansion slot on the structural support and whether the left support or the right support is located (row positioning).

Taking a left bracket as an example, PCIe 1-3 are arranged on the left bracket, and three dotted frames on the side wall of the bracket in FIG. 7 are the mounting positions of three Riser cards, corresponding to the three PCIe slots. The Riser card and PCIe slots in fig. 7 are in one-to-one correspondence, i.e., one PCIe slot on each Riser card. Here, the structural support has, in addition to the function of the conventional support, three sets of positioning contacts, namely, a Riser card column positioning contact (an example of a first sub-positioning contact set), a Riser card row positioning contact (an example of a second sub-positioning contact set), and a support row positioning contact (an example of a second positioning contact set), each set of positioning contacts having 3 bits (the number of slots of the positioning contacts can be increased or decreased as required, as long as the number of slots can be covered by the code).

The Riser card column alignment contacts have a total of three bits, column 1, column 2 and column 3, respectively, from left to right (indicating the position in a column). When the Riser card is installed in the PCIe1 position, contact column 1 (gray-marked positioning contact of the Riser card column positioning contacts in fig. 7) is in contact with the Riser card, and column 2 and column 3 (white-marked positioning contact of the Riser card column positioning contacts in fig. 7) contacts are not in contact with the Riser card; when the Riser card is installed in the PCIe2 position, contact column 2 is in contact with the Riser card and columns 1 and 3 are not in contact with the Riser card. When the Riser card is installed at different positions in the column direction, the contacted contacts are different and can be used as column identifiers of PCIe slot positions.

The Riser card row positioning contacts have a total of three bits, row 1, row 2 and row 3, respectively, from left to right. When a Riser card is installed at any one of the positions PCIe1, 2, 3, contact row 1 (grey marked ones of the Riser card row positioning contacts in fig. 7) is in contact with the Riser card, and row 2 and row 3 (white marked ones of the Riser card row positioning contacts in fig. 7) contacts are not in contact with the Riser card. Since the Riser cards in these 3 positions are all on the same shelf, their corresponding rows are identical (here, the left shelf is defined as row 1). The three PCIe slot rows 1 are all connected together and are connected with the bracket row positioning contacts.

The support row positioning contacts have three bits in total, namely row 1, row 2 and row 3 from left to right. When the bracket is mounted on the chassis, the bracket row positioning contacts will contact the chassis base. After the left bracket in fig. 7 is installed, the contact row 1 is in contact with the chassis base, and the contact rows 2 and 3 are not in contact with the chassis base. Thus, the structural supports are arranged at different positions in the row direction of the chassis base, and the row identifications of the contacts are different.

With the positioning contact configuration in this embodiment, the slot indication information stored in the designation register of the riser card mounted on each expansion slot is a positioning code generated based on the positioning contact point contacted by the metal copper exposure area of the riser card mounted on each expansion slot, that is, a positioning code generated based on the position of the positioning contact point contacted by the metal copper exposure area of the riser card mounted on each expansion slot in the belonging positioning contact point group.

In this embodiment, for each expansion slot, the corresponding slot indication information is fixed, and does not depend on the connection relationship with the expansion port or whether the adapter card is installed, so a code mapping table may be preconfigured to record the correspondence relationship between the expansion slot in the plurality of expansion slots and the corresponding positioning code. Correspondingly, through analyzing the target slot indication information, the extension slot in which the associated adapter card is installed in the plurality of extension slots is determined, and the method comprises the following steps: and inquiring a preset coding mapping table by using target slot indication information, and determining the inquired expansion slot as the expansion slot on which the associated adapter card is installed.

Alternatively, for each riser card, after the riser card is mounted to the corresponding expansion slot, the slot indication information required to be stored can be determined, and thus, the slot indication information can be determined and stored in the designated register at any time after the riser card is mounted to the expansion slot.

For example, the Riser card not only provides a function of connecting the PCIe peripheral device with the PCIe port of the CPU, but also converts the position information on the structural support into a digital signal through a circuit and sends the digital signal to the slot identification system, and the slot identification system can determine the slot position where the PCIe peripheral device is located through the position information. When the Riser cards are installed at the positions of PCIe 1-6 slots, the corresponding positioning codes of each Riser card can be determined. The encoded information for the 6 PCIe slots on the server may be stored in a slot code mapping table as shown in table 1.

TABLE 1

As can be seen from Table 1, PCIe slots are in one-to-one correspondence with the rank locating codes of the slots. The PCIe slot position of the Riser card can be known only by the identification system acquiring the positioning code transmitted by the Riser card, so that the position of the PCIe peripheral device arranged on the Riser card is known.

Through this embodiment, through the extension slot group that different positioning contact group identification adapter card was installed to belongs to and the position in the extension slot group that belongs to, can conveniently carry out extension slot location, improve extension slot identification's convenience and accuracy.

In some exemplary embodiments, the first set of positioning contacts of the plurality of first positioning contact sets corresponding to the associated riser card is an associated positioning contact set, and the metallic copper-exposed area of the associated riser card includes a set of first contact points for contacting positioning contacts of a first subset of the associated positioning contact sets, and a set of second contact points for contacting positioning contacts of a second subset of the associated positioning contact sets. For the associated riser card, it may determine slot position information corresponding to the associated expansion slot, i.e., target slot position information, after being mounted to the associated expansion slot, and store the determined target slot position information in a designated register thereon. The steps described above may be performed by a processing chip associated with the transit card. Alternatively, the processing chip may be an IO Expander chip, and the register is designated as an IO Expander register.

The processing chip may include a first set of pins corresponding to a first sub-set of positioning contacts in the associated set of positioning contacts, which may be connected to a first set of contact points, and a second set of pins corresponding to a second sub-set of positioning contacts in the associated set of positioning contacts, which may be connected to a second set of contact points. Because the level of the positioning contact contacted with the metal copper exposure area of the associated adapter card is different from the level of the positioning contact not contacted with the metal copper exposure area of the associated adapter card, the pin level of the first pin, which is contacted with the corresponding positioning contact, of the connected first contact point is different from the pin level of the first pin, which is not contacted with the corresponding positioning contact, of the connected first contact point; for a set of second pins, the pin level of the second pin of the connected second contact point in contact with the corresponding positioning contact point is different from the pin level of the second pin of the connected second contact point not in contact with the corresponding positioning contact point.

In this embodiment, the extended slot group to which the associated extended slot belongs may be determined according to the pin levels of different second pins in the set of second pins, and the position of the associated extended slot in the extended slot group to which the associated extended slot belongs may be determined based on the pin levels of different first pins in the set of first pins, so as to implement slot identification. Correspondingly, before the slot indication information stored in the designated register of the associated transit card is acquired, the method further comprises the steps of: determining, by the processing chip, a set of pin levels of the first pin and a set of pin levels of the second pin; and generating target slot indicating information according to the pin level of the first pin and the pin level of the second pin.

For example, the Riser card not only provides the function of connecting the PCIe peripheral device to the CPU PCIe port, but also converts the location information on the structural support into a digital signal through a circuit and sends the digital signal to the identification system. When the Riser card is arranged on the support, a metal copper exposure area exists at a position on the PCB corresponding to the row-column contact on the support, and after the metal copper exposure area contacts with the support contact, a closed loop is formed between the metal copper exposure area and a related circuit group on the Riser card, so that position information is converted into a digital coding signal and sent to the identification system. The server case and the internal support are both made of metal, the server is connected with the ground after being put on the shelf, and the circuit board in the case is equivalent to the ground after being contacted with the case or the metal structural part.

In combination with the identification circuit in the Riser card shown in fig. 8, when the Riser card is installed at the PCIe1 to 6 slot positions, pin levels of the IO Expander chip on the Riser card are different, and coding information read through the I2C (Inter-INTEGRATED CIRCUIT, integrated circuit bus) is also different. The encoded information for the 6 slots on the server is shown in table 1.

When the Riser card is mounted at the uppermost PCIe slot position of the left bracket, pins Pin1 and Pin4 of the Riser card circuit IO Expander are in contact with a Riser card column positioning contact_column 1 and a Riser card row positioning contact_row1 on the structural bracket, the pins are equivalent to the ground, the level is pulled down, and the level is still high due to the existence of a pull-up resistor in other bits. If the Riser card is installed at the middle position of the right bracket, pins Pin2 and Pin5 of the Riser card circuit IO Expander are contacted with a Riser card column positioning contact_column 2 and a Riser card row positioning contact_row2 on the structural bracket, the pins are equivalent to the ground, the level is pulled down, and the level of other bits is still high due to the existence of a pull-up resistor. Thus, when the Riser is mounted on the structural support, the pin level of the IO Expander chip in the Riser card changes. The level change is transmitted as digital information to a slot identification system through an I2C bus to carry out slot identification. The slot recognition system herein may be a system that performs device slot recognition, which may be the aforementioned management system.

Here, the position identifier (i.e., position information) is automatically formed according to the positions where the Riser card and the structural support are installed, and the position identifier is converted into digital code information through a designed circuit (as shown in fig. 8), and the slot identification system completes automatic identification of the PCIe slot through the code information. The structural support and the Riser card in the scheme can be arranged at any position of the design, and PCIe ports on the main board can be connected to any PCIe slots according to actual needs without fixing, so that the server is very flexible to use. Meanwhile, the Riser card and the structural support can be used at any PCIe slot position without one PCIe slot position, and as only one Riser card and one structural support are needed, the production and the installation are convenient, the production cost is saved, and the boring and stagnation problem caused by excessive materials is avoided.

Through this embodiment, through setting up the pin that corresponds with different sub-location contact sets to carry out the slot identification based on the pin level that detects, can improve convenience and the efficiency of slot identification.

In some example embodiments, determining that there is a mounted expansion port of the mounted expansion devices in the plurality of expansion ports may be at any desired time. Alternatively, in this embodiment, each expansion port in the plurality of expansion slots may be scanned by a BIOS (Basic Input/Output System) to determine whether an expansion device is mounted on each expansion port when the electronic device is turned on.

For example, after the server is powered on, the BIOS may scan all PCIe ports of the CPU for mounted PCIe devices.

According to the embodiment, the expansion slot position on which the expansion equipment is mounted is detected when the equipment is started, so that the expansion equipment can be conveniently and conveniently used based on the slot position identification result in the running process of the equipment, and the timeliness of information acquisition is improved.

In some exemplary embodiments, the expansion port and the riser card mounted on the expansion slot may be connected by a sideband signal bus. Correspondingly, for a scenario that a mounted expansion port of the mounted expansion device exists in the plurality of expansion ports, slot indication information stored in a designated register of the associated adapter card is obtained, and target slot indication information is obtained, including: accessing a designated register of the associated transit card through a sideband signal bus of the mounted expansion port to acquire slot indication information stored in the designated register of the associated transit card, thereby acquiring target slot indication information.

The sideband signal bus described above may be a bus for transmitting sideband signals between an expansion port and a riser card, the sideband signals being signals for transmitting specific information between devices, these signals typically being used to assist a primary communication protocol. The sideband signal buses used may be the same or different for different expansion ports and riser card types, and may include, but are not limited to, at least one of the following: I2C, I3C (Improved I2C, improved integrated circuit bus) may also include other buses, which are not limited in this embodiment.

For example, the IO Expander register on the corresponding Riser card may be accessed through a sideband signal bus of the PCIe port on which the PCIe device is mounted, thereby reading the location encoding information stored therein.

According to the embodiment, the appointed register of the transfer card is accessed through the sideband signal bus to acquire the slot indication information stored in the appointed register, so that the influence of slot identification on the operation of the electronic equipment can be reduced, and the performance of the operation of the equipment is improved.

In some exemplary embodiments, determining whether an expansion port of the mounted expansion device exists may be performed by the BIOS, acquiring the slot indication information may be performed by the BMC (Baseboard Management Controller ), and in this manner, slot identification may be performed by the BMC without affecting operation of the main operating system, in which case the foregoing slot identification system may be operated by the BMC.

Correspondingly, for the case that the mounted expansion port of the mounted expansion device exists in the expansion ports, accessing the designated register of the associated transit card through the sideband signal bus of the mounted expansion port comprises: sending a notification message to the baseboard management controller through the basic input output system; in response to receiving the notification message, the designated register of the first riser card is accessed by the baseboard management controller via the sideband signal bus of the mounted expansion port. The notification message may be used to notify the baseboard management controller to access a designated register of the associated riser card, which may be a specific instruction that may be sent to the BMC via an interrupt signal.

For example, if a device mounted on a PCIe port is scanned, the BIOS informs the BMC to access the IO Expander register on the corresponding Riser through the sideband signal bus of the PCIe port. The BMC acquires the coding information stored in the IO Expander register on the corresponding Riser card and compares the coding information with the mapping table shown in the table 1, so that the PCIe slot bit installed by the corresponding Riser card is obtained.

According to the embodiment, when the existence of the expansion port on which the expansion device is mounted is detected, the BMC performs slot identification without affecting the operation of the main operating system, so that the influence of the slot identification on the operation of the electronic device can be reduced, and the operation performance of the device is improved.

In some exemplary embodiments, the sideband signal bus used to access the expansion card's designated registers may be an integrated circuit bus, which may allow for other signals transmitted on the electronic device (the integrated circuit bus may transmit multiple signals), while allowing for existing device versions, reducing device upgrade costs.

Correspondingly, for the case that the mounted expansion port of the mounted expansion device exists in the expansion ports, accessing the designated register of the associated transit card through the sideband signal bus of the mounted expansion port comprises: the designated registers of the associated riser card are accessed via the integrated circuit bus on which the expansion port has been mounted.

For example, the BIOS informs the BMC to access the IO Expander register on the corresponding Riser card via the I2C bus on which the PCIe port of the device is mounted.

Through the embodiment, the appointed register of the transfer card is accessed through the integrated circuit bus, other signals transmitted on the electronic equipment can be considered, the existing equipment version is considered, the equipment upgrading cost can be reduced, and the compatibility of slot identification is improved.
