All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without any creative effort belong to the protection scope of the present application.

The rapid development of network technology makes people have higher requirements on out-of-band manageability and controllability of servers. Through out-of-band management, engineers can connect to corresponding servers through networks at any place to perform a series of management and maintenance, and do not need to stay in a noisy laboratory environment for a long time.

NCSI (Network Controller base Interface) is an industry standard for a Sideband Interface Network Controller defined by the Distributed Management Task Force (DMTF) to support out-of-band Management of servers. Fig. 1 is a structural diagram of an NCSI communication system in the prior art, as shown in fig. 1, in the prior art, a network card is connected to a motherboard through a gold finger, and a server needs to connect the network card to the motherboard through an NCSI cable, so as to implement NCSI communication. When the network card needs to support the NCSI, the scheme needs additional NCSI cables and connectors, which increases the cost and the design complexity.

The core of the application is to provide an NCSI communication system, method, device and medium, which are used for reducing the waste of cost and making the design more concise when carrying out NCSI communication.

In order that those skilled in the art will better understand the disclosure, the following detailed description is given with reference to the accompanying drawings.

Fig. 2 is a structural diagram of an NCSI communication system provided in an embodiment of the present application, as shown in fig. 2, including a motherboard and a network card, where an NCSI signal in a gold finger connector of the network card is multiplexed to JTAG signal pins and RSVD signal pins, and the NCSI communication system further includes a switch chip;

the network card is connected with the slot of the mainboard through the golden finger connector, and the golden finger connector of the network card is connected with the NCSI unit and the JTAG unit of the network card through the switching chip so as to form an NCSI channel and a JTAG channel;

Fig. 3 is a schematic diagram of a design of a network card gold finger according to an embodiment of the present application, in which JTAG signal pins and RSVD signal pins are multiplexed, for example, JTAG2 is modified to NCSI _ RXD0 and JTAG4 is modified to NCSI _ TXD0 in fig. 3, so that when the network card is connected to a motherboard through a gold finger, receiving and sending of NCSI data can be implemented, and NCSI communication is implemented. The JTAG interface (Joint Test Action Group) is an international standard Test protocol (IEEE 1149.1 compliant) and is mainly used for chip internal Test.

It can be understood that, in order to save extra connectors and cables, the NCSI signal is multiplexed to the JTAG signal pins and RSVD signal pins, and in order to implement JTAG and NCSI communication, a switching chip needs to be added to the network card, and the switching chip connects the NCSI unit and the JTAG unit of the gold finger connector and the network card to form an NCSI channel and a JTAG channel. After receiving the control signal, the control chip can switch on the NCSI channel or the JTAG channel, thereby realizing different communication modes. In a specific implementation, the control chip is a data selector (MUX), and the function of the MUX is mainly to switch signals. The integrated analog electronic switch has become a leading product in the small signal field, and compared with the conventional mechanical contact type electronic switch, the integrated electronic switch has many advantages, such as high switching speed, no jitter, power saving, small volume, reliable operation, easy control, and the like.

In a specific implementation, the control signal may be manually adjusted, or may be controlled by the server through a switch, and in this embodiment, the switching device of the control signal is a jump cap. The jump cap is a connector for connecting two male pins, and is similar to a switch of a certain function or circuit on a circuit board. Plug and unplug jumpers are commonly used to alter certain arrangements of circuit boards. In this embodiment, the switching of the control signal can be realized by plugging and unplugging the jump cap.

NCSI signals transmitted by GOLD FINGER connectors (GOLD filters) of the network cards are respectively transmitted to JTAG units and NCSI units of the network cards after passing through MUX switching chips. The MUX defaults that the channel of the connector NCSI is connected, the JATG channel is disconnected, and the NCSI communication is realized by default; when the network card needs to perform boundary scan detection through JATG, the MUX _ EN signal can be sent out through the jump cap to switch the channel to the JATG channel, namely the JATG channel is switched on, and the NCSI channel is switched off.

The NCSI communication system provided by the embodiment of the application comprises a mainboard and a network card, wherein NCSI signals in a golden finger connector of the network card are multiplexed to JTAG signal pins and RSVD signal pins, and the NCSI communication system further comprises a switching chip; the network card is connected with the slot of the mainboard through the golden finger connector, and the golden finger connector of the network card is connected with the NCSI unit and the JTAG unit of the network card through the switching chip so as to form an NCSI channel and a JTAG channel; the switching chip switches and conducts the NCSI channel or the JTAG channel under the action of the control signal.

And a switching chip is added in the network card to realize the switching between the JATG function and the NCSI function. By adopting the technical scheme, the cost of the connector and the cable is saved, and the design is simpler.
