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.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a reset control system of a BIOS and a BMC according to the present invention, which is applied to a server, and the reset control system includes:

It should be noted that the resetting of the BIOS and the BMC includes two processes, the first process is that the BIOS and the BMC perform configuration information clearing after receiving a reset signal (i.e., a first level), specifically, the BIOS and the BMC clear their configuration information after receiving the reset signal, where the configuration information includes the previously updated BIOS firmware and BMC firmware; the BIOS can send an emptying signal to the CPLD after emptying the configuration information of the BIOS, and the BMC can also send an emptying signal to the CPLD after emptying the configuration information of the BMC; the second process is that the CPLD sends a restart signal to the power supply after receiving the reset signal (namely the first level), the emptying signal of the BMC and the emptying signal of the CPLD, the power supply turns off and restarts the output of the power supply after receiving the restart signal, the BIOS and the BMC are powered off and then powered on, and the BIOS and the BMC reload default firmware after being powered off and then powered on, thereby realizing the reset. The reset process of the BIOS and BMC is the same as in the prior art, except that the first level is sent to the BIOS, BMC, and CPLD.
In order to solve the problem that a server cover needs to be opened in the prior art, the reset control system of the BIOS and the BMC provided in the application includes a reset button 1 and a level control module 2, wherein the reset button 1 is disposed outside the server, so that a worker can conveniently reset the BIOS and the BMC by pressing the reset button 1 when hardware reset is required to be performed on the BIOS and the BMC. The level control module 2 is connected with the reset button 1, and controls the reset button 1 to output a first level to the BIOS, the BMC and the CPLD when the reset button 1 is pressed down so as to realize the reset of the BIOS and the BMC; when the reset button 1 is not pressed, the reset button 1 is controlled to output a second level to the BIOS, the BMC and the CPLD so as not to trigger the BIOS and BMC reset. Wherein the first level and the second level are opposite levels. In the present application, whether the first level is specifically a high level or a low level is not particularly limited, and is determined according to actual conditions.
The invention provides a BIOS and BMC reset control system, which comprises a reset button 1 and a level control module 2, wherein the reset button 1 is arranged outside a server, when the BIOS and BMC are required to be reset, a cover does not need to be opened, and in some cases (for example, when the reset button 1 is arranged on a front panel of the server), even the server does not need to be pulled out of a cabinet, so that the reset operation process of the BIOS and the BMC is simplified, and the labor and the time are saved.
Referring to fig. 2, fig. 2 is a schematic structural diagram of another BIOS and BMC reset control system according to the present invention; on the basis of the above-described embodiment:
as a preferred embodiment, the reset button 1 comprises a housing, a control module, and a first contact 21, a second contact 22 and a movable contact 23 disposed in the housing, wherein:
the movable end of the movable contact 23 is connected with the control module, and the immovable end of the movable contact 23 is respectively connected with the BIOS, the BMC and the CPLD;
the first contact 21 and the second contact 22 are connected with the level control module 2;
when the control module is pressurized, the movable contact 23 is connected with the second contact 22;
when the pressure applied by the control module is released, the movable contact 23 is connected with the first contact 21;
the level control module 2 is configured to output a first level to the second contact 22 and output a second level to the first contact 21.
In this embodiment, the reset button 1 is a three-contact button, and the movable contact 23 can be operated by the control module, that is, the control module controls which contact the movable contact 23 is connected to.
Specifically, the level control module 2 outputs a first level to the second contact 22 and outputs a second level to the first contact 21. When the control module is applied with pressure, the movable contact 23 is connected with the second contact 22, the level of the movable contact 23 is the same as that of the second contact 22, and the movable contact 23 outputs a first level to the BIOS, the BMC and the CPLD; when the control module is not pressed, the movable contact 23 is connected with the first contact 21, and the level of the movable contact 23 is the same as that of the first contact 21, and the movable contact 23 outputs a second level to the BIOS, the BMC and the CPLD.
The reset button 1 provided by the embodiment has a simple structure and a small volume. Of course, the reset button 1 may have other structures, and the present embodiment is not particularly limited herein.
As a preferred embodiment, the housing is provided with an opening, the control module is disposed in the housing, the control module includes an elastic member and a slider, wherein:
the elastic piece is arranged between the shell and the sliding block, and the sliding block is connected with the movable contact 23;
when pressure is applied to the sliding block through the opening, the sliding block drives the movable contact 23 to be connected with the second contact 22, and the elastic piece deforms;
when the pressure is released, the elastic element is reset so that the slider is reset and the slider brings the movable contact 23 into connection with the first contact 21.
It is considered that if the reset button 1 is protruded outside the server, a false triggering may often occur. In order to solve this problem, in this embodiment, the reset button 1 is a hidden button.
Referring to fig. 3, fig. 3 is a schematic structural diagram of a reset button 1 according to the present invention.
In fig. 3, the contacts 11 and 15 correspond to the first contact 21 in fig. 2, the contacts 12 and 14 correspond to the second contact 22 in fig. 2, and the contact 13 corresponds to the movable contact 23 in fig. 2, wherein the first contact 21, the second contact 22, and the movable contact 23 are contact pieces. In practical applications, any one of the second termination point 11 and the contact 15 of the pull-up resistor R1 may be used, and any one of the second termination point 12 and the contact 14 of the pull-down resistor R2 may be used.
Specifically, an opening is provided on the housing, the control module is provided in the housing, and the control module includes an elastic member and a slider, the elastic member is provided between the housing and the slider (in fig. 2, the elastic member is provided on the opening side of the housing, and of course, the elastic member may be provided on the side close to the contact), and the slider is connected to the movable contact 23. When pressure is applied to the slider, the slider moves, and the movable contact 23 is driven to move.
Further, when pressure is applied to the slider through the opening, the slider moves to bring the movable contact 23 into connection with the second contact 22, and the elastic member deforms (is in a stretched state); when the pressure is released, the elastic element is reset, the slider is reset and the slider drives the movable contact 23 to connect with the first contact 21.
It can be seen that, because the slider is arranged in the shell of the reset button 1, if a user presses the button, the user needs to stretch the hand into the shell through the opening to press the slider, so that the risk of mistaken pressing is greatly reduced, and the normal work of the server is ensured.
As a preferred embodiment, the elastic member is a spring.
In particular, the spring has the advantages of simple structure and low cost. Of course, the elastic member may be other types of elastic members, and the present application is not limited thereto.
As a preferred embodiment, the first level is a low level, and the second level is a high level;
the level control module 2 includes:
resetting the power supply Vcc;
a capacitor C;
a pull-up resistor R1 having a first end connected to a reset power supply Vcc and a second end connected to a first end of a capacitor C, a common end of the pull-up resistor R1 connected to the capacitor C being connected to the first contact 21, and the second end of the capacitor C being grounded;
the first terminal of the pull-down resistor R2 and the pull-down resistor R2 are grounded, and the second terminal of the pull-down resistor R2 is connected to the second contact 22.
Specifically, the first level may be a low level, and the second level is a high level. In this embodiment, the level control module 2 includes a reset power Vcc, a capacitor C, a pull-up resistor R1, and a pull-down resistor R2, where the pull-up resistor R1 is connected to the reset power Vcc, so that the second end of the pull-up resistor R1 outputs a high level to the first contact 21. The pull-down resistor R2 is grounded, so that the second terminal of the pull-down resistor R2 outputs a low level to the second contact 22.
In this embodiment, the specific first level and the specific second level and the structure of the level control module 2 are not particularly limited, and are determined according to actual situations.
As a preferred embodiment, further comprising:
a first jumper pin having a first end connected to the first contact 21 and a second end connected to a second end of the pull-up resistor R1;
a second jumper pin with a first end connected with the movable contact 23 and a second end connected with the BIOS, the BMC and the CPLD respectively;
and a third jumper pin having a first terminal connected to the second contact 22 and a second terminal connected to the second terminal of the pull-down resistor R2.
Specifically, in order to solve the problem, three jumper pins are further provided between the reset button 1 and the level control module 2 in this embodiment, in consideration that in some cases, the reset button 1 may malfunction, and at this time, the BIOS and the BMC cannot be reset. When the reset button 1 fails, if the BIOS and the BMC do not need to be reset at the moment, the jumper cap can be inserted into the first jumper pin and the second jumper pin, and the first jumper pin and the second jumper pin are equivalently connected, so that the second jumper pin is output to output high level to the BIOS, the BMC and the CPLD; if the BIOS and the BMC need to be reset, the jump caps on the first jumper pin and the second jumper pin can be taken off, the jump caps are inserted into the second jumper pin and the third jumper pin, and the connection of the second jumper pin and the third jumper pin is equivalent to that of the second jumper pin and the third jumper pin, so that the second jumper pin outputs low level to the BIOS, the BMC and the CPLD.
It should be further noted that, if the reset button 1 does not malfunction, no jumper cap is inserted on any of the three jumper pins, and at this time, the three jumper pins are equivalent to wires, which has no influence on the user to adjust the reset button 1.
Therefore, the reset control system provided by the embodiment does not affect the reset control of the BIOS and the BMC even if the reset button 1 fails, and improves the reliability and stability of the reset control.
As a preferred embodiment, the reset button 1 is provided on the front panel of the server.
In order to further facilitate the user to reset and control the BIOS and the BMC, the reset button 1 can be arranged on the front panel of the server, so that the user does not need to pull the server out of the cabinet, the reset operation process of the BIOS and the BMC is further simplified, and the labor and the time are saved.
The invention also provides a server which comprises the BIOS and the reset control system of the BMC.
