[0133] In some embodiments of the present application, the method for controlling power on and off of a PCIe card further includes, after step S103, prohibiting power on and off of the PCIe card if the judgment result is no.

[0134] In some embodiments of the present application, the PCIe card is powered on and off, including generating an IPMI instruction and modifying the power enable signal of the slot where the PCIe card is located, so as to realize powering off and then powering on the PCIe card.

[0135] In some embodiments of the present application, powering off and then powering on the PCIe card can implement a cold restart, thereby ensuring that the PCIe card recovers from a failure and operates normally, or enabling a firmware update to take effect.

[0136] In some embodiments of the present application, the IPMI instruction is used by the BMC to modify the IO pin level of the IO expansion chip; the BMC transmits the IPMI instruction to the IO expansion chip through the I2C signal.

[0137] In some embodiments of the present application, when the server is running a service, a PCIe card has a fault and needs debugging or a firmware upgrade, after-sales or operation and maintenance personnel can obtain the device information of the PCIe card through the operating system, and control the power supply of the slot where the PCIe card is located through the BMC out-of-band management tool IPMI command to realize the power on and off function of the PCIe card.
