P12v_stby: AC power input by the server power supply refers to 220V AC power input by the server power supply input. 220V alternating current is connected to a power input end of the server through a power line (namely an AC line). 220V alternating current is converted into two direct currents of P12V_main and P12V_STBY in the server power supply. Both of these are 12V voltages, except that the current provided by p12v_main is larger, and in addition p12v_main needs to receive a power enable signal to be converted into system mean power to output voltage to other chips or components. And the current provided by the P12V_STBY is smaller, and the P12V_STBY automatically outputs voltage after being inserted into an AC line without power supply enabling signal control. The 12V STBY is typically converted to p3v3_stby or other small voltage to power components such as CPLD for earlier chip use in the board card. After the server is started, the P12V_main is converted into other system main voltages to be used for chips or parts which work after the starting in the board card, such as a CPU, a memory, a hard disk and a fan lamp.

The CPLD monitors the PSU1_POWER_GOOD, PSU1_EN, PSU2_POWER_GOOD, PSU2_EN signal states, and P12V_STBY signal states of the first PSU and the second PSU.
Working principle: when a user is in a power-off test (or in a power supply abnormality scene, one power supply is suddenly abnormal), and one power supply test is closed (the AC mains supply is closed), the CPLD can monitor a plurality of signal states of the two PSUs. For example, after one power supply is disconnected, the other power supply is immediately cut off according to the redundant mode of the power supply, and the server is not down; however, in the abnormal situation, after one power is lost, the other power is not switched in time, so that the server is in large-area downtime; at the moment, the signal states of the two PSUs are monitored to clearly confirm whether the signal states are problems at the server side or factors of the on-site power supply environment of the machine room. Under normal conditions, the states monitored by the signals CPLD, namely PSU1_POWER_GOOD, PSU1_EN, PSU2_POWER_GOOD, PSU2_EN and P12V_STBY, are all high-level states, if any signal is abnormal, the CPLD informs the detection manager, the detection manager generates a log, and the detection manager can alarm through a buzzer. When the psu1_power_good, psu1_en, psu2_power_good, psu2_en, p12v_stby signals are always in a normal state, such as after AC mains is cut off, the server is down, and at this time, if psu2_power_good, psu2_en, p12v_stby signals of psu2 are all pulled low, this indicates that the customer POWER supply environment is problematic. If the PSU2_POWER_GOOD, PSU2_EN and P12V_STBY signals are unchanged, but are down, the problem of the reliability of the redundant logic of the server is solved.
The embodiment of the invention provides a server power module state detection device, and the embodiment of the invention also provides a server power module state detection method corresponding to the device based on the server power module state detection device described in the embodiment.
Fig. 7 is a flowchart of a method for detecting a state of a power module of a server according to an embodiment of the present invention, as shown in fig. 7, the method includes the following steps.
S1, receiving a main power supply module state signal, a standby power supply module state signal and a server standby power supply signal.
S2, recording the main power supply module state signal, the standby power supply module state signal and the server standby power supply signal into a log.
The maintainer can analyze the fault reasons according to the signals recorded in the log. For example, when the main power supply module is switched to the standby power supply module, if the power supply environment of the standby power supply module is normal, that is, the uninterrupted power supply is normal, the state signal of the standby power supply module and the standby power supply signal of the server are both in a normal state, no abnormal phenomenon occurs, and if a downtime fault occurs at this time, the server redundant logic reliability is abnormal. If the power supply environment of the standby power supply module is abnormal, that is, when the uninterruptible power supply is abnormal, the state signal of the standby power supply module and the standby power supply signal of the server are abnormal, and at the moment, a downtime fault occurs, and the situation that the power supply environment of the standby power supply module is abnormal can be judged. When the standby power supply module is switched to the main power supply module, if the power supply environment of the main power supply module is normal, namely, the mains supply is normal, the state signal of the main power supply module and the standby power supply signal of the server are both in a normal state, no abnormal phenomenon occurs, and if a downtime fault occurs at the moment, the server redundancy logic reliability is abnormal. If the power supply environment of the main power supply module is abnormal, namely, the mains supply is abnormal, the state signal of the main power supply module and the standby power supply signal of the server are abnormal, and at the moment, a downtime fault occurs, so that the power supply environment of the main power supply module can be judged to be abnormal. The maintenance personnel can look up the state signal of the main power supply module and the standby power supply signal of the server in the log, and the fault cause can be determined according to the state of the state signal of the main power supply module and the standby power supply signal of the server.
In an alternative embodiment, the fault cause may be automatically determined, and specifically includes the following steps.
S1, receiving a main power supply module state signal, a standby power supply module state signal and a server standby power supply signal.
S2, receiving a server state signal and a power supply switching signal.
And S3, recording the main power supply module state signal, the standby power supply module state signal and the server standby power supply signal into a log.
And S4, responding to the downtime of the server during power supply switching, analyzing the fault reason according to the power supply module state signal and the server standby power supply signal, and recording the fault reason to a log.
The step S4 specifically includes: responding to the server downtime when the main power supply module is switched to the standby power supply module, and judging that the power supply environment of the standby power supply module is abnormal if the state signal of the standby power supply module and the standby power supply signal of the server are abnormal; and if the standby power supply state signal and the server standby power supply signal are normal, judging that the reliability of the redundant logic of the server is abnormal. Responding to the server downtime when the standby power supply module is switched to the main power supply module, and judging that the power supply environment of the main power supply module is abnormal if the state signal of the main power supply module and the standby power supply signal of the server are abnormal; and if the main power supply state signal and the server standby power supply signal are normal, judging that the reliability of the redundant logic of the server is abnormal.
