Description
Technical Field
The present invention relates to the field of server technologies, and in particular, to a server chassis intrusion detection circuit, method, apparatus, and storage medium.
Background
In the field of servers, the design of chassis intrusion switches is indispensable. The chassis intrusion switch is a spring device mounted to the chassis and connected to the baseboard management controller of the motherboard by a cable. When the case cover is closed, the spring is retracted under the influence of pressure, and the main board receives a high-level state. When the case cover is opened, the spring is sprung, and the main board receives a low-level state. The baseboard management controller judges the state of the case cover according to the level state.
The state of the case cover is judged through the case intrusion switch, the case cover is convenient to record, the server maintenance personnel can further conveniently analyze the operation maintenance history of the server, and meanwhile, the substrate management controller can conveniently conduct targeted control according to the case cover opening condition, and the influence on the inside of the case after the case cover is opened is reduced.
FIG. 1 is a schematic diagram of a prior art connection state of a chassis intrusion detection circuit in a chassis open state; fig. 2 is a schematic diagram of a connection state of a chassis intrusion detection circuit in the prior art in a chassis cover closing state.
As shown in fig. 1, a 2 pin (pin) connector U1 is used on the motherboard and connected to the chassis intrusion switch S by a cable. The case intrusion switch S typically has 3 pins, where COM is a common terminal, NO is a normally open contact, i.e., is disconnected from the common terminal COM under natural conditions, and NC is a normally closed contact, i.e., is connected to the common terminal COM under natural conditions. The 1pin of the connector U1 is connected to the common terminal COM and pulled up to the standby power p3v3_stby through a resistor of 4.7kΩ, and the other pin of the connector U1 is connected to ground through a resistor of 100 Ω.
When the chassis is uncapped, as shown in fig. 1, a common end COM of the chassis intrusion switch S is connected with the normally closed contact NC, and a chassis uncap detection signal receiving end intruder_n signal of the baseboard management controller (Baseboard Management Controller, BMC) inputs a low level to the baseboard management controller through a 4.7kΩ resistor and a 100 Ω resistor voltage division; when the enclosure is closed, as shown in fig. 2, the common terminal COM of the enclosure intrusion switch S is disconnected from the normally closed contact NC, and the enclosure open detection signal receiving terminal intruier_n signal of the baseboard management controller is pulled up to a high level.
To summarize, when the chassis cover is closed, the spring of the chassis intrusion switch S is compressed, so that the chassis cover-opening detection signal receiving end intruier_n of the baseboard management controller inputs a high level; when the chassis cover is opened, the spring of the chassis intrusion switch S springs up, so that the chassis cover detection signal receiving end intruier_n of the baseboard management controller inputs a low level. Therefore, according to the signal type input by the case cover opening detection signal receiving end INTRUDER_N, the baseboard management controller can determine the opening and closing conditions of the case cover, and further performs targeted control.
However, in the server production and assembly link, if the producer forgets to plug wires or damage cables (break between the connector and the chassis intrusion switch or between the connector and the baseboard management controller), the chassis uncovering detection signal receiving end intruder_n of the baseboard management controller always keeps a high level under the action of the pull-up resistor. The high level input by the chassis opening detection signal receiving end intruder_n is a normal signal for the baseboard management controller, that is, the baseboard management controller cannot distinguish whether the chassis opening is in a closed state or a signal that the chassis opening cannot be detected due to poor communication with the chassis opening switch, in other words, when the chassis is opened, the chassis opening signal fed back by the chassis opening switch cannot be fed back to the baseboard management controller, so that the baseboard management controller cannot perform corresponding control and management, and in general, a worker cannot notice the problem when performing the chassis opening inspection. Thus, this problem cannot be intercepted in the production link, resulting in bad aircraft flow to the end user; it is also difficult to find easily during daily use, resulting in a baseboard management controller control leak.
The technical problem that can in time indicate staff's problem when forgetting the plug wire or cable damage causes quick-witted case invasion switch and baseboard management controller intercommunication to be unsmooth because of the production personnel is provided, is the technical problem that the skilled person need solve.

The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
Example 1
Fig. 3 is a schematic diagram of a connection state of a server chassis intrusion detection circuit in a chassis uncapped state according to an embodiment of the present application; fig. 4 is a schematic diagram of a connection state of a server chassis intrusion detection circuit in a chassis cover closing state according to an embodiment of the present application.
As shown in fig. 3, the server chassis intrusion detection circuit provided in the embodiment of the present application includes: the system comprises a chassis invasion switch S, a connector U2, a first pull-down resistor R1, a first voltage dividing resistor R2 and a baseboard management controller;
wherein the case intrusion switch S is a single-pole double-throw switch; the first end of the first pull-down resistor R1 is connected with the common end COM of the chassis invasion switch S through a first channel in the connector U2, the first end of the first pull-down resistor R1 is also connected with the chassis uncovering detection signal receiving end INTRUDER_N of the baseboard management controller, and the second end of the first pull-down resistor R1 is grounded; the first end of the first voltage dividing resistor R2 is connected with a first direct current VCC1, and the second end of the first voltage dividing resistor R2 is connected with a normally open contact NO of the chassis invasion switch S through a second channel in the connector U2;
When the case is in a cover closing state, the case invasion switch S is arranged at the normally closed contact NC; when the case is in a cover opening state, the case intrusion switch S is arranged on the normally open contact NO; the first voltage dividing resistor R2 is configured to output a high level at a first end of the first pull-down resistor R1 after being connected to the first pull-down resistor R1;
the baseboard management controller is used for: when the high level is input to the case cover opening detection signal receiving end INTRUDER_N, the case is confirmed to be in a cover closing state; when the case cover opening detection signal receiving end INTRUDER_N inputs a low level, confirming that the case is in a cover opening state; and when the chassis uncovering detection signal receiving end INTRUDER_N inputs a low level and lasts for a first preset duration after the machine is started, the abnormal alarm of the chassis intrusion detection circuit is carried out.
On the basis of a chassis intrusion detection circuit in the prior art, the server chassis intrusion detection circuit provided by the embodiment of the application modifies the line sequence of the chassis intrusion switch S, uses the normally open contact NO and the common terminal COM, and modifies the hardware of the server main board, so that the chassis uncap detection signal receiving end intruder_n of the baseboard management controller is pulled down through the first pull-down resistor R1, and defaults to input a low level to the baseboard management controller, and a second channel in the connector U2 is pulled up to the first direct current power supply VCC1 through the first voltage dividing resistor R2.
When the server chassis intrusion detection circuit provided by the embodiment of the application is applied, as shown in fig. 3, the common end COM of the chassis intrusion switch S and the normally open contact NO are disconnected when the chassis is opened, so that the chassis opening detection signal receiving end intruder_n of the baseboard management controller inputs a low level. When the chassis is closed, as shown in fig. 4, the common terminal COM of the chassis intrusion switch S is connected to the normally open contact NO, so that the chassis open detection signal receiving terminal intruier_n of the baseboard management controller inputs a high level after being divided by the first voltage dividing resistor R2 and the first pull-down resistor R1. If the cable is forgotten to be damaged or the cable is forgotten to be damaged, the chassis opening detection signal receiving end INTRUDER_N of the baseboard management controller always inputs a low level, which is an abnormal signal, and if the baseboard management controller continuously receives the low level input by the chassis opening detection signal receiving end INTRUDER_N for a first preset time after the equipment is started, the chassis intrusion detection switch is considered to be abnormal, and a worker is reminded to check whether the chassis intrusion detection circuit is abnormal or not or whether the chassis forgets to close the cover through an alarm, so that the problem of the chassis intrusion detection circuit is found in the production stage of the equipment; if the problem of abnormality of the chassis intrusion detection circuit occurs in normal use of the terminal user, the problem of abnormality of the chassis intrusion detection circuit can be timely determined by the server chassis intrusion detection circuit provided by the embodiment of the application.
Optionally, if the chassis cover opening detection signal receiving end intruder_n of the baseboard management controller inputs a low level after the machine is started, the baseboard management controller may perform the chassis intrusion detection circuit abnormality alarm after the low level signal continues for a second preset time period (less than the first preset time period). If the chassis cover opening detection signal receiving end INTRUDER_N of the baseboard management controller inputs a high level after the baseboard management controller is started, then the first preset time length is used as an evaluation standard, namely, after the first preset time length is continuously input a low level at a certain time point, the chassis intrusion detection circuit abnormality alarm is performed.
In a specific implementation, the first voltage dividing resistor R2 is configured to output a high level at a first end of the first pull-down resistor R1 after being connected to the first pull-down resistor R1, that is, when the resistance value of the first voltage dividing resistor R2 and the resistance value of the first pull-down resistor R1 are selected, the first voltage dividing resistor R2 and the voltage value corresponding to the high level required by the chassis opening detection signal receiving end intruder_n of the baseboard management controller need to be determined according to the voltage value provided by the first direct current power VCC1, so as to ensure that the chassis opening detection signal receiving end intruder_n of the baseboard management controller can input the high level through the first voltage dividing resistor R2 and the first pull-down resistor R1 after being connected to the first voltage dividing resistor R2 through the common end COM, the normally open contact NO and the connector U2 of the chassis intrusion switch S, so as to prompt the chassis opening state of the baseboard management controller.
The abnormal alarm mode of the chassis intrusion detection circuit by the baseboard management controller can be that an alarm (such as a buzzer, an indicator lamp and the like) connected with the baseboard management controller is controlled to send out an alarm signal, or the chassis intrusion detection circuit abnormal log is generated by the baseboard management controller and is reported to the central processing unit, and then the central processing unit controls the user interface to display the abnormal alarm information of the chassis intrusion detection circuit.
Alternatively, the first direct current power VCC1 may specifically be a standby 3.3V power supply, the first pull-down resistor R1 specifically is a 20kΩ resistor, and the first voltage dividing resistor R2 specifically is a 1kΩ resistor.
Example two
In the foregoing embodiment, if the baseboard management controller receives the low level input from the chassis open cover detection signal receiving end intruder_n for a first preset period of time after the device is started, it is considered that there may be a case intrusion detection circuit abnormality or a case forgetting to close the cover. In order to further facilitate the positioning problem of the staff, based on the above embodiment, as shown in fig. 3 and 4, the server chassis intrusion detection circuit provided in the embodiment of the present application further includes a second pull-down resistor R3 and a second voltage dividing resistor;
The first end of the second pull-down resistor R3 is connected with the second end of the second voltage dividing resistor through a third channel in the connector U2, the first end of the second pull-down resistor R3 is also connected with a cable in-place identification signal end INTRUDER_prsnt of the baseboard management controller, and the second end of the second pull-down resistor R3 is grounded; the first end of the second voltage dividing resistor is connected with the second direct current power supply, and the second voltage dividing resistor is used for outputting high level at the first end of the second voltage dividing resistor after being communicated with the second voltage dividing resistor;
correspondingly, the baseboard management controller is also used for carrying out abnormal alarm on the cable of the chassis intrusion detection circuit when receiving the low input level of the cable in-place identification signal terminal INTRUDER_prsnt.
In a specific implementation, by adding another resistor voltage-dividing circuit composed of a second pull-down resistor R3 and a second voltage-dividing resistor based on the third channel of the connector U2, the second pull-down resistor R3 is simultaneously connected with the cable of the baseboard management controller at the bit identification signal terminal intruder_prsnt, and is used for pulling to the bottom when the resistor voltage-dividing circuit is not connected, so as to provide a low level for the cable of the baseboard management controller at the bit identification signal terminal intruder_prsnt; and through designing the resistance value voltage division of the second voltage division resistor and the second pull-down resistor R3, after the resistor voltage division circuit is communicated, a high level is provided for a cable of the baseboard management controller at the bit identification signal end INTRUDER_prsnt.
