Technical Field

The invention relates to the technical field of servers. The invention further relates to a device for health detection of the indicator light and a using method thereof.

Background

The conditions that cables are not well plugged or a hardware single body breaks down and the like due to human factors are frequently encountered in the whole machine production process of equipment such as a server and the like, so that a hardware link is broken, and some status indicator lamps of the whole machine cannot work normally. In some cases, for example, once a fault indicator lamp fails to work normally, when a server actually fails, the indicator lamp fails to indicate a corresponding fault, which may result in more serious adverse effects.

in order to verify that the status indicator lamp itself and its hardware link including the interface are normal, a common approach is to test the status indicator lamp before the device leaves the factory. However, the factory test of the whole machine generally only focuses on the indicator light that should be turned on when the equipment is in a normal state, and for some indicator lights that are not turned on in a normal state, especially for some fault indicator lights that are not turned on in most cases on the equipment that is about to be shipped, it is difficult to recognize the situation that the fault indicator lights cannot be turned on normally. And manual control lighting detection is carried out on all the status indicator lamps, so that time and labor are consumed, and the problems of missing detection and the like of equipment due to manual negligence can occur. Meanwhile, if a special test interface is not made in the early stage of lighting control of some state indicator lamps, manual direct lighting operation cannot be realized in the later stage. These situations can leave a potential hazard for the status indicator lights in subsequent status indicating operations.

therefore, a detection device and a detection method for improving detection capability of all status indicator lamps are needed, so that testability of the whole device can be improved and quality of a server can be better ensured under the condition that normal hardware functions are not affected.

Detailed Description

while the present invention may be embodied in various forms, there is shown in the drawings and will hereinafter be described some exemplary and non-limiting embodiments, with the understanding that the present disclosure is to be considered an exemplification of the invention and is not intended to limit the invention to the specific embodiments illustrated.

fig. 1 shows a schematic view of an embodiment of an apparatus 100 for indicator light health detection according to the present invention. In the embodiment shown in fig. 1, the apparatus 100 comprises at least:

An indicator lamp 10, the indicator lamp 10 being turned on or off according to a command;

A function control device 20, the function control device 20 being configured to issue a function instruction for the indicator lamp 10;

a test interface 30, the test interface 30 configured to receive an input test signal;

the analysis device 40 is connected to the test interface, and is configured to analyze the test signal and send a test instruction;

A path selection device 50, the output of the path selection device 50 being connected to the indicator light 10, a first input of the path selection device 50 being connected to the function control device 20 and a second input of the path selection device 50 being connected to the evaluation device 40,

Wherein, the path selection device 50 is configured to gate the path between the first input end and the output end by default so that the indicator light 10 performs status indication according to the functional instruction;

And, the path selection device 50 is further configured to, in response to receiving the test instruction, gate the path between the second input terminal and the output terminal so that the indicator light 10 performs the health detection according to the test instruction.

It should be noted that the device 100 for indicating lamp health detection according to the present invention generally comprises a plurality of indicating lamps 10, each connected to the output terminal 50 of the channel selection device.

In the device 100 for health detection of indicator light of the present invention, on one hand, the function control device 20 is connected to the first input terminal of the channel selection device 50 through the function control bus of the indicator light, and usually, the function control device 20 is preferably a device originally used by a server to control the indicator light to indicate the status according to the function, and the function control device 20 and the function control bus together form the original normal function link of the indicator light. When the indicator lamp needs to work normally, the path selection device 50 gates the path between the first input end and the output end, and communicates the indicator lamp with the original function control device 20 through the function control bus, so that the indicator lamp 10 performs the state indication under the normal working condition according to the function instruction sent by the original function control device 20.

On the other hand, the resolver 40 is connected to a second input of the path selector 50 via a test control bus (indicated by a dashed line in fig. 1) of the indicator, and the resolver 40 is in signal communication with the test interface 30 and receives the test signal from the test interface 30. At the same time, the analyzer 40 analyzes the test signal to issue a test command. The analysis device 40 and the test control bus together form a test link of the indicator light. When the health detection of the indicator light is required, the path selection device 50 shields the first input end and gates the path between the second input end and the output end, and the indicator light is communicated with the analysis device 40 through the test control bus, so that the indicator light 10 performs the health detection according to the test instruction analyzed by the analysis device 40. For example, before the server leaves a factory, the test interface 30 injects a corresponding test signal into the whole machine, the corresponding test instruction is transmitted to the indicator lamps through the analysis of the analysis device 40, so that all the indicator lamps are lightened, whether the indicator lamps and hardware links thereof have faults or not can be known by observing the on-off state of the indicator lamps, if the interface is not plugged or cables are broken, the judgment can be directly carried out by observing the state of the indicator lamps, and once the faults on the hardware occur, a worker can be timely maintained or replaced.

In order to prevent the interference of the test link to the normal lighting operation of the indicator lamp during normal operation, the path selection device 50 not only plays a role of switching the control signals, but also plays a role of isolating the interference between different control signals. In addition, the path selection device 50 defaults to the path between the function control device 20 and the indicator lamp, and reduces the influence of the test control bus of the indicator lamp on the original state indication function to the maximum extent.

In some embodiments of the device 100 for indicating lamp health detection of the present invention, the parsing device 40 is a decoder, the test interface 30 is a GPIO (General Purpose Input/Output) interface, preferably an SGPIO (Serial General Purpose Input/Output), and the decoder receives a Serial test signal Input from the test interface 30 and parses the test signal into a parallel test command. Particularly, when it is required to perform health detection on a plurality of indicator lamps 10 simultaneously, the analyzer 40 may convert the external serial indicator lamp test signal into parallel test instructions separated and independent from each other to light up the corresponding indicator lamps 10, as shown in fig. 2.

in a further embodiment of the device for health detection of indicator light of the present invention, the decoder is one of a CPLD, a single chip microcomputer, or an application specific integrated circuit. Preferably, the decoder is a CPLD, and accordingly the CPLD analyzes the serial indicator light test signal input from the GPIO interface. Here, a device or a module capable of analyzing the test signal injected from the test interface 30 to obtain the test instruction of each indicator light 10 is included in the scope according to the present invention.

In still other embodiments of the apparatus 100 for indicating lamp health detection of the present invention, the parsing device 40 is a BMC, and the test Interface 30 is an IPMI Interface, wherein the BMC receives a test signal input from the IPMI (Intelligent platform management Interface) Interface and parses the test signal into a parallel test command. Particularly, when it is required to perform health detection on a plurality of indicator lamps 10 simultaneously, the external serial indicator lamp test signals injected from the IPMI interface can be converted into parallel test instructions separated and independent from each other by the analysis device 40, that is, the BMC, so as to light up the corresponding indicator lamps 10, as shown in fig. 2.

In one or more embodiments of the apparatus 100 for indicating light health detection of the present invention, the path selection means 50 is an alternative data selector MUX (multiplexer). In the process of multi-path data transmission, any one path can be selected according to requirements, and the path is called a data selector, also called a multiplexer or a multi-path switch. In the device 100 for indicating lamp health detection according to the present invention, an alternative data selector is preferably used as the path selection device 50, and two inputs are respectively connected to the function control device 20 and the analysis device 40.

In a further embodiment of the device 100 for indicator light health detection of the present invention, the alternative data selector comprises at least one of a plurality of individual multiplexers or a multi-channel integrated multiplexer or a CPLD. That is to say, the one-out-of-two data selector may be implemented by a plurality of mutually separated one-out-of-two multiplexers, or by a multi-channel one-out-of-two integrated multiplexer, or by a CPLD completing the function of the multi-channel one-out-of-two multiplexer according to coding, and mainly completing the switching of the normal functional link and the test link to control the indicator light 10.

in some embodiments of the apparatus 100 for indicating lamp health detection of the present invention, the path selection device 50 is configured to gate the path between the first input terminal and the output terminal when the control pin is switched to the low state, and to gate the path between the second input terminal and the output terminal when the control pin is switched to the high state. When selecting a device of the path selection apparatus 50 or programming, the control pin of the path selection apparatus 50 for path selection adopts a strategy of gating a functional control path (i.e., a path of a first input terminal and an output terminal) when a low level is switched in, and switching to a test control path (i.e., a path of a second input terminal and an output terminal) when a high level is switched in.

In several embodiments of the device 100 for indicating lamp health detection of the present invention, the test command issued by the parsing device 40 includes a high signal for the control pin. The parsing means 40 sends out the parsed test command and also sends a high level signal for the control pin to inform the path selection means 50 of the path switching.

In another aspect, the invention further provides a use method of the device for indicating lamp health detection in any one of the preceding embodiments. Fig. 3 shows a schematic block diagram of an embodiment of the method, which comprises at least the following steps as shown in fig. 3:

S3: the path selection device gates the path between the analysis device and the indicator lamp according to the test instruction so as to carry out health detection on the indicator lamp and the interface thereof according to the analyzed test instruction.

That is, the method of using the device 100 according to the present invention at least comprises the steps of firstly inputting the test signal from the test interface 30 in step S1, then receiving the test signal in step S1 by the parsing device 40 in step S2 and parsing the test signal into the test command, and then sending the test command by the parsing device 40, after the test command sent by the parsing device 40 in step S2 is received by the path selecting device 50, the path selecting device 50 gates the path between the parsing device 40 and the indicator lamp 10, so as to perform the health check of the indicator lamp 10 and its interface according to the parsed test command.
