Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the method, the upper cover of the case needs to be opened to manually modify the jump cap, so that the method is inconvenient in practical application, is not friendly to users, has high requirements on the users, and needs the users to clearly switch the jump cap modes of different network cards, otherwise, the risk of setting errors exists.
The method and the device determine the network card in place by using the detection module, and inform the switching control module to realize the circuit conduction of the BMC and the network card in place, the whole operation is automatically executed by the system, the action of workers is not needed, the user has no threshold limit, and the NCSI access efficiency of the network card is higher.
The embodiment of the invention discloses a network card NCSI function self-adaptive system, which is shown in figure 1 and comprises a switching control module 1 and a detection module 2, wherein:
a first access port NCSI _ A of the switching control module 1 is connected with an NCSI port of the BMC, a second access port NCSI _ B of the switching control module 1 is connected with an NCSI port of a first network card, and a third access port NCSI _ C of the switching module is connected with an NCSI port of a second network card;
the detection module 2 is specifically configured to:
starting a switching control module 1;
detecting whether the first network card and the second network card are in place;
when the first network card and/or the second network card are/is in place, a network card to be connected is determined in the first network card and the second network card, and the switching control module 1 is informed to conduct an internal passage of a first passage port NCSI _ A and a second passage port NCSI _ B or a third passage port NCSI _ C corresponding to the network card to be connected;
and when the first network card and the second network card are not in place, closing the switching control module 1.
It can be understood that, after the switching control module 1 is started, the detection module 2 detects whether the first network card and the second network card are in place according to the preset frequency, and if any network card is in place, the switching control module 1 is notified that the signal for turning on the in-place network card and the BMC is turned on, specifically, if the network card to be connected is the first network card, the internal channel of the first channel port NCSI _ a and the internal channel of the second channel port NCSI _ B corresponding to the network card to be connected are turned on, and if the network card to be connected is the second network card, the internal channel of the first channel port NCSI _ a and the internal channel of the third channel port NCSI _ C corresponding to the network card to be connected are turned on. If no network card is in place, the switching control module 1 is closed to save power consumption; and then, the first network card and the second network card are still detected according to the preset frequency, when the network cards are in place, the switching control module 1 is started, and the switching control module 1 is informed to conduct the corresponding internal channels. It can be understood that this operation is to save the power consumption of the switching control module 1 when there is no network card in place, but also consider the response speed of the detection module 2 and the switching control module 1 when there is a network card in place, so a hysteresis waiting period may be set, and if the network card is restored to the on state in the hysteresis waiting period, the switching control module 1 continues to keep the on state.
It can be understood that, in this embodiment, the first network card and the second network card may select a home network card, and currently, commonly-used home network cards include a gigabit network card and a gigabit network card, and in this embodiment, the first network card and the second network card may select two gigabit network cards, or one gigabit network card and one gigabit network card, and fig. 1 is a corresponding configuration in this case.
Furthermore, because only one NCSI line is routed from the BMC to the switching control module 1 in the embodiment, compared with two NCSI lines where the BMC respectively goes to two switching control switches in the prior art, fewer lines are routed in the embodiment, and the stub can be reduced in response, so that the signal integrity is improved, and the stability of the whole system is improved.
The embodiment of the application determines the in-place network card by using the detection module and informs the switching control module to realize the circuit conduction of the BMC and the in-place network card, the whole operation is automatically executed by the system, the action of workers is not needed, the user has no threshold limit, and the NCSI access efficiency of the network card is higher.

when only the first network card is in place, determining the first network card as a network card to be connected;
and when only the second network card is in place, determining the second network card as the network card to be connected.
Further, in actual operation, the first network card may be selected as a gigabit network card, and the second network card may be selected as a gigabit network card.
Further, the detection module 2 is specifically configured to:
and when the first network card and the second network card are in place, determining the second network card as the network card to be connected according to the priority rule.
It is understood that the priority rule herein sets the priority of the first network card (gigabit network card) to be lower than that of the second network card (gigabit network card) in order to provide better performance preferentially, but may also be set according to other priority rules, and the priority rules are not limited.
Of course, if the types of the first network card and the second network card are the same, any network card can be randomly selected as the network card to be connected.
