The complex programmable logic module 101 determines the state of the first circuit board level power signal, and each of the LED lights 102 respectively displays the state of the first circuit board level power signal of each of the circuit boards. (Here, the first board-level power signal state is the board-level power signal state), which in turn informs the maintenance personnel which board 103 is faulty (ie, powered down), so that the circuit of the abnormal board can be further advanced. Troubleshoot. The logical AND operation result between the different voltages of each of the circuit boards 103 is displayed on the corresponding LED lamp 102 of the circuit board 103.

It should be noted that the first logical operation is a logical AND operation. For example, When the output voltage or output current of one of the circuit boards 103 is normal, the output is 1, and if the output voltage or the output current is abnormal, the output is 0. Thus, the corresponding board-level power signal state is obtained by a logic operation (eg, an AND operation, an OR operation, an OR operation, etc.), and the complex programmable logic module 101 determines the board-level power signal state. As long as the output voltage (or output current) of one of the circuits is abnormal, the complex programmable logic module 101 determines that the corresponding circuit board 103 is abnormal, that is, the corresponding LED light 102 is not bright. Further, it is determined that the circuit board 103 has failed. It can be seen from the above that the present invention not only improves the hardware structure of the conventional CPLD, but also forms the complex programmable logic module 101 of the present invention, and also utilizes the complexity of the complex programmable logic module 101. For the remaining time (for example, before or after the power-on self-test), the various circuit boards 103 of the server 100 are normally operated (ie, in power supply) or malfunctioned (ie, powered down), and faults are accurately detected and positioned. In Improve the efficiency of troubleshooting work.

Specifically, when the complex programmable logic module 101 determines a first When the state of the first board level power signal of a target circuit board is abnormal, the first target circuit board is an abnormal circuit board. It should be noted that the first target circuit board is the above-mentioned circuit board 103. The complex programmable logic module 101 is switched to the first target circuit board by using a software mode of the CPLD, and acquires at least one circuit end power signal state of the first target circuit board, and the at least one The circuit side power signal state performs a second logic operation to form a first circuit end power signal state. The complex programmable logic module determines a state of the first circuit end power signal, and each of the LED lights 102 switches to display a state of the first circuit end power signal corresponding to the first target circuit board. The state of the first circuit end power supply signal is a power signal state of each circuit on the circuit board 103. For example, if the output voltage (or output current) of one of the circuits of the first target circuit board is normal, the output is 1, and if the output voltage (or output current) is abnormal, the output is 0. If the output voltage (or the output current) is abnormal, the first target circuit board is abnormal, that is, the corresponding LED lamp 102 is not lit, thereby determining that the circuit is faulty. It should be noted that LED lights 102 and complex programmable logic are not limited. The module 101 is specifically disposed on which circuit board 103.

Referring to Figures 2 and 3, for example, the first LED light 102 is used to display A board level power signal state of the second riser board 202. The second LED lamp 102 is used to display a board level power signal state of the first riser board 201. The third LED lamp 102 is used to display a board level power signal status of the motherboard 204. The fourth LED lamp 102 is used to display a board level power signal state of the main converter board 203. The complex programmable logic module 101 collects each monitored circuit board 103 of the server 100 (including the first riser board 201, the second riser board 202, the third riser board 203, and The circuit-side power signal state of the motherboard 204) and a logic signal state of at least one of the circuit terminals are logically operated to form a board-level power signal state of each of the circuit boards 103. The complex editable logic module determines a board level power signal state of the circuit board 103, and each of the LED lights 102 respectively indicates a corresponding one of each circuit board 103 in a lighted/off manner. A board-level power signal state. When the maintenance personnel finds that the third LED lamp 102 is turned off, it can immediately judge that the motherboard 204 is malfunctioning, that is, power is lost. Then, the complex programmable logic module 101 is switched to the motherboard 204 to obtain the state of the plurality of circuit end power signals of the motherboard 204.

At this time, the output voltage of the first LED lamp 102 corresponding to the display motherboard 204 is The first circuit of +12V, the second LED lamp 102 corresponds to the second circuit showing that the output voltage of the motherboard 204 is +5V, and the third LED lamp 102 corresponds to the third output voltage of the motherboard 204 is +3.3V. The fourth LED lamp 102 corresponds to a fourth circuit that displays an output voltage of the motherboard 204 of +1.5V. When the fourth LED lamp 102 is found to be extinguished, the fourth circuit indicating that the output voltage of the motherboard 204 is +1.5 V has failed. It should be noted that an embodiment of the present invention is only for explaining that the fourth circuit of the motherboard 204 is faulty, the complex programmable logic module 101 and corresponding LEDs. In the case of the lamp 102, when the other circuit boards 103 are faulty, the complex programmable logic module 101 and the corresponding LED lamp 102 are similar, and are not described herein again.

When the complex programmable logic module 101 determines a second target When the state of the first circuit end power signal of the road board is abnormal, the second target circuit board is an abnormal circuit board. It should be noted that the second target circuit board is the above-mentioned circuit board 103. The complex programmable logic module 101 acquires the first target circuit board by switching to a first target circuit board (not shown) passing through one of the plurality of circuit boards 103 And the at least one circuit end power supply signal state of the two target circuit boards, and performing a third logic operation on the at least one circuit end power supply signal state to form a second circuit end power supply signal state. The complex programmable logic module 101 determines the state of the second circuit end power signal, and each of the LED lights 102 switches to display the state of the second circuit end power signal corresponding to the second target circuit board, that is, Each of the LED lamps 102 switches from displaying a normal operation (ie, in power supply) or a failure (ie, power down) state of each of the circuit boards 103 to displaying only the second circuit terminals in the second target circuit board. Power signal status. Then, it can be determined which circuit of the abnormal circuit board is faulty.

For another example, referring to FIG. 2 and FIG. 3, the first LED lamp 102 is used for display. A board level power signal state of the second riser board 202 is shown. The second LED lamp 102 is used to display a board level power signal state of the first riser board 201. The third LED lamp 102 is used to display a board level power signal status of the motherboard 204. The fourth LED lamp 102 is used to display a board level power signal state of the third riser board 203. The complex programmable logic module 101 collects each monitored circuit board 103 in the server 100 (including the first riser board 201, the second riser board 202, the motherboard board 204, and the third The power supply signal state of the circuit end of the adapter board 203), and Performing a logic operation on at least one circuit end power signal state to form a board level power signal state of each circuit board 103, the complex editable logic module determining a board level power signal state of the circuit board 103 And each of the LED lamps 102 respectively indicates a first board-level power signal state of each of the corresponding circuit boards 103 in a lighting/extinguishing manner.

When the maintenance personnel finds that the fourth LED light 102 is off, it can be judged immediately. The third adapter board 203 fails, which means that the power is turned off. Then, the maintenance personnel switch to the jumper on one of the first transfer board 201, the second transfer board 202, the third transfer turn 203, and the motherboard board 102 (here, the motherboard 204) to The third adapter plate 203 is configured to acquire a plurality of circuit end power signal states of the third riser board 203, wherein the jumper mode may be a metal connection line connecting two demand points in a vertical manner, or two connected in a horizontal manner. The metal connection line of the demand point, and the specific jumper method is not limited to this, only according to the actual situation. At this time, the first LED lamp 102 corresponds to the first circuit that displays the output current of the third interposer 203 is 7.6A, and the second LED lamp 102 corresponds to the output current of the third interposer 203 that is 6.0A. In the second circuit, the third LED lamp 102 corresponds to a third circuit that outputs an output current of the third interposer 203 of 5.0A, and the fourth LED lamp 102 corresponds to the output current of the third interposer 203 that is 1.0A. Four circuits. When the second LED lamp 102 is found to be off, the second circuit indicating that the output current of the third riser board 203 is 6.0A has failed. It should be noted that an embodiment of the present invention is only for explaining the case where the second circuit of the third riser board 203 fails, the complex programmable logic module 101 and the corresponding LED lamp 102, and other circuit boards. The situation when the fault occurs in 103 is similar, and will not be described here.

It can be seen from the above that when the first of each of the circuit boards 103 is determined When the state of the power signal of the circuit end is abnormal, the circuit board 103 is an abnormal circuit board, and can be transmitted in two ways: one is a software mode (ie, CPLD switching), and the other is a physical mode (ie, Jumper). The jumper switch) switches to the abnormal circuit board, and each LED lamp 102 displays the state of the circuit side power signal of the corresponding circuit board 103.

The first target group is a packet at a board group level, and the second board level power signal state is a board level power signal state.

When the complex programmable logic module 101 determines a third target circuit When the state of the second board-level power signal of the board is abnormal, the third target board is different Common circuit board. The complex programmable logic module is switched to each of the circuits of the third target circuit board by the third programmable jumper of the complex programmable logic module 101 or one of the plurality of circuit boards 103 The group 101 acquires the state of the at least one circuit end power signal of the third target circuit board, and performs a sixth logic operation to form a third circuit end power signal state, and at the same time, the plurality of LED lights 102 switch display Corresponding to the third circuit end power signal state of each of the circuits.
