In the description of the present invention, unless otherwise explicitly limited, terms such as arrangement, installation, connection and the like should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific contents of the technical solutions.
Some embodiments of the present invention provide a VPX blade power-up control method, referring to fig. 1 and fig. 2, including:
110, acquiring a first control signal sent by a processor of the VPX blade;
120, detecting the first control signal to obtain first detection data;
130, determining the power-on working state of the VPX blade according to the first detection data;
and 140, controlling the power module of the VPX blade to be powered on according to the power-on working state.
In an exemplary embodiment, the control method is implemented by using a power supply controller, a VPX blade is a blade type board card conforming to a VPX standard, a first control signal sent by a processor of the VPX blade is used to directly control a power-on working state of the power supply controller, and the power supply controller obtains first detection data according to a detection result after receiving the first control signal, where the first detection data includes: and receiving the first control signal, and not receiving the first control signal. And when the first control signal is received, namely the power-on normal working state is obtained, and at the moment, the power-on work of the power supply controller is controlled according to the first control signal sent by the processor of the VPX blade. When the first control signal is not received, the power supply controller is in a power-on abnormal working state, and at the moment, the power supply controller automatically controls power-on working. In the control method, the VPX blade is powered on at last under different power-on working states, and only the specific power-on flow of the power controller is different. And the power supply controller controls a plurality of power supply modules on the VPX blade to be powered on according to the self-determined power-on working state.
In some embodiments, the power-on operating state includes a power-on abnormal state, and determining the power-on operating state of the VPX blade according to the first detection data includes:
and if the first control signal is not detected within the preset time, determining that the working state of the VPX blade is a power-on abnormal state.
In one embodiment, when the VPX blade is inserted into the chassis, the processor and the power controller of the VPX blade start to work under the default enabling of 3.3V of the VPX blade, the power controller is preset with a detection time, for example, within 500ms, a first control signal is detected, namely the processor is in a normal working state, and the power controller is controlled by the processor and controls when the power controller enables other working modules on the VPX blade to be powered on to work. If the processor does not respond after waiting for 500ms, namely the processor does not receive the first control signal, the power controller directly starts to control other working modules to be powered on at the moment, so that the processor can still normally work under the condition of processor failure.
Some embodiments control power-up of a power module of a VPX blade according to a power-up operating state, comprising:
and controlling the power supply module of the VPX blade to be powered on according to the preset configuration according to the power-on abnormal state.
When the power supply controller is in a power-on abnormal state, the power supply controller controls power-on of power supply modules of other working modules on the VPX blade according to internal preset, and then the power supply controller starts to work normally. Specifically, when a plurality of Power modules need to be powered on, the Power modules are configured in advance, firstly, the Power switch outputs a 12V working voltage, the Power switch outputs a 12V _ PGOOD feedback signal to the Power controller in a state that the voltage output is normal, after the Power controller receives the 12V _ PGOOD signal, it is determined that the Power switch normally works, at this time, an RTM _ PWREN control signal is output, an enable signal end of the first Power module is controlled, the first Power module works, the first Power module outputs a RTM _ Power supply signal, the first working module is controlled to work, and meanwhile, the first Power module returns a RTM _ PGOOD signal to the Power controller to notify the Power controller to start working by normal Power on. After receiving the RTM _ PGOOD feedback signal, the power controller sends a control signal of PWREN1 to control the second power module to work, and the specific work flow is the same as that of the first power module, which is not described herein. And sequentially powering on the third power supply module and the fourth power supply module according to the same power-on working mode, so that the whole VPX blade starts to work normally, the power-on process of the whole VPX blade is completed, and after ALL the power supply modules are powered on, the power supply controller outputs a feedback signal of ALL _ PWR _ PGOOD to the processor to inform the processor that ALL the power supply modules are powered on normally. In other embodiments, all power modules may be controlled to be powered on simultaneously.
Some embodiments, obtaining a first control signal sent by a processor of a VPX blade, further comprises:
and acquiring a second control signal sent by the chassis management controller through a processor of the VPX blade, and sending a first control signal according to the second control signal.
The processor is in communication connection with the case management controller on the case by adopting an IPMB bus and is used for receiving a second control signal sent by the case management controller.
Some embodiments, obtaining a first control signal sent by a processor of a VPX blade, further comprises:
and if the processor of the VPX blade does not acquire the second control signal sent by the chassis management controller, stopping sending the first control signal.
When the processor of the VPX blade does not acquire the second control signal, namely, the chassis management controller or the IPMB fails, the processor of the VPX blade stops sending the first control signal. The process is started when the VPX blade is inserted into the chassis and still stays in the preset waiting time of the power controller, the first control signal is stopped being sent at the moment, namely the process is the same as the case that the processor fails in the embodiment, and the power controller directly starts to control other working modules to be powered on, so that the chassis management controller or the IPMB bus can still work normally when the chassis management controller or the IPMB bus fails.
The present invention further provides a VPX blade power-on control circuit, referring to fig. 2, including: the power controller is used for controlling power-on of a power module of the VPX blade according to a first control signal and executing the power-on control method of the VPX blade in the embodiment, the processor is connected with the power controller, and the processor is used for obtaining a second control signal sent by the chassis management controller and sending the first control signal according to the second control signal. The processor is a Micro Control Unit (MCU) and is in communication connection with the power controller by adopting an IPMB bus and is used for transmitting a second control signal.
In some embodiments, the power supply controller is a programmable logic device. For example, the hardware circuit can be a field programmable gate array FPGA or a complex programmable logic device CPLD, and a program can be flexibly set according to the user requirements to complete the design of the hardware circuit. In other embodiments, the logic circuit can be built for other electronic elements.
In some embodiments, the enable terminal of the programmable logic device is grounded through a pull-down resistor for placing the programmable logic device in a power-on operating state. In this embodiment, the enable terminal of the programmable logic device is grounded through the pull-down resistor, when the VPX blade is inserted into the chassis and powered on, the programmable logic device defaults to automatically control the power module to be powered on, but the processor outputs a high-level signal, i.e., a PAY _ PWREN signal in the figure, to the enable terminal of the programmable logic device in the first time under the condition of normal operation, so that the programmable logic device stops operating, and the processor determines the operating time of the programmable logic device according to negotiation communication with the chassis management controller, i.e., the programmable logic device is in a control state of normal operation. When the communication between the processor and the chassis management controller is in a problem or the processor fails, a high level signal output by the processor disappears, and the enabling end of the programmable logic device automatically changes into a low level through the pull-down resistor, so that the programmable logic device automatically starts to work and controls the power module to be powered on.
The control flow of the control circuit for powering up the VPX blade is described in detail in an embodiment. Referring to fig. 3, after the VPX blade is inserted into the chassis, the power controller and the processor start to operate, the power controller detects a first control signal within a preset time period, and when the first control signal is not detected, the power controller controls the power modules to be sequentially powered on. When the power controller detects a first control signal, the power detection controller is controlled by the processor, the processor immediately outputs a high-level signal, the step that the power controller automatically powers on is stopped, then the processor is communicated with an external case controller, when the processor detects a second control signal, the second control signal sent by the case management controller controls the first control signal to be output, so that whether the power controller powers on or not is controlled, if the case management controller controls the power controller to power on, the power controller sequentially controls the power modules to power on, and detects whether all the power modules successfully power on or not according to a feedback signal returned by the power modules, if all the power modules successfully power on, the power on is completed, and the VPX blade normally works. And if one of the power supply modules is not electrified successfully, the power supply control module stops working, and the VPX blade is not electrified. When the processor does not detect the second control signal, the processor stops outputting the first control signal, and the power controller is used for automatically controlling the power modules to be sequentially powered on until the power-on is finished.
The VPX blade comprises the VPX blade power-on control circuit, and under the condition that a chassis management controller or a processor fails, the VPX blade can still be powered on, and service processing of the VPX blade cannot be influenced.
