Optionally, in this embodiment, fig. 3 is a schematic diagram of a server link connection according to an embodiment of the present application, as shown in fig. 3, where a DEVICE link in a server is provided with two response chips (response 0, response 1), one PCIe switch chip and two PCIe DEVICEs (DEVICE 0, DEVICE 1), a debug interface of the response chip is an I2C (Inter-Integrated Circuit, two-wire serial bus) interface, an interface of the PCIe switch chip is a UART (Universal Asynchronous Receiver/Transmitter) interface, the server link may further include a BMC and a CPU, an I2C interface of the response chip on a hardware line is connected to the BMC, and a PCIe interface of the PCIe switch chip is connected to the BMC, where communications may be performed based on a UART protocol. The BMC (or CPU) can acquire the current connection state of the target protocol link corresponding to the target communication protocol (PCIe protocol) in the server, and determine the current connection condition of the target protocol link.
In one exemplary embodiment, the current connection state of the target protocol link corresponding to the target communication protocol in the server may be obtained, but is not limited to, by: acquiring a target connection parameter of the target protocol link, wherein the target connection parameter is a corresponding connection parameter under the condition that the target protocol link is normally connected; detecting the current connection parameter of the target protocol link, wherein the current connection parameter is a connection parameter in the current connection process of the target protocol link; and determining the current connection state of the target protocol link according to the target connection parameter and the current connection parameter.
Optionally, in this embodiment, the target protocol link corresponding to the target communication protocol in the server may include multiple target protocol links, and for each target protocol link, obtaining a corresponding target connection parameter may be adopted and a current connection parameter of the target protocol link is detected, where the target connection parameters between the multiple target protocol links may be the same or different, for example, each target protocol link in the multiple target protocol links may have a different target connection parameter due to a difference in transmission data or configuration parameters.
Alternatively, in this embodiment, the target connection parameter may be, but not limited to, directly obtained from the stored data, or may be obtained from a history connection record of the target protocol link, where the connection parameter is under the condition that the target protocol link is normally connected, as the target connection parameter.
Alternatively, in this embodiment, the target connection parameter may be, but not limited to, one or more parameters, where each parameter may indicate a current connection situation of the target protocol link, for example, a link rate or a link bandwidth of the target protocol link.
In one exemplary embodiment, the current connection state of the target protocol link may be determined from the target connection parameter and the current connection parameter, but is not limited to, by: comparing the target connection parameter with the current connection parameter; under the condition that the target connection parameter is consistent with the current connection parameter, determining that the current connection state indicates that the current connection of the target protocol link is normal; and under the condition that the target connection parameter is inconsistent with the current connection parameter, determining that the current connection state indicates the current connection fault of the target protocol link.

The RETIMER chip is used for prolonging the transmission distance of PCIe signals, and signal attenuation is compensated by regenerating and re-timing PCIe signals, so that the quality and reliability of the signals are improved. PCIe Switch chips are chips used to connect multiple PCIe devices, which typically have multiple PCIe ports between which forwarding and routing can take place, thereby enabling communication and data transfer between the multiple PCIe devices. PCIe Switch chips may also support other high speed bus protocols such as Ethernet and InfiniBand.

Specifically, the heartbeat lamp is usually a periodic flashing signal sent by an LED indicator lamp, and the frequency and period of the flashing signal can be adjusted according to the working state of the specific device. Normally, when the device is in a normal working state, the heartbeat lamp will flash periodically to indicate that the device is working normally, and provide services for users. If the equipment is abnormal or fails, the flicker frequency and period of the heartbeat lamp may change or the flicker is stopped, and at this time, a user can judge whether the equipment works normally according to the change of the heartbeat lamp signal. By observing the state of the heartbeat lamp, whether the equipment works normally or not can be judged quickly, and the reliability and stability of the equipment can be improved.

After the server is started, the BMC monitors heartbeat lamp signals of the RETIMER chip and the PCIe switch chip to judge whether the chip is in a normal working state.

Optionally, in this embodiment, the target connection parameter may include, but is not limited to, a link connection parameter and a device operation parameter, where the link connection parameter is used to indicate a connection condition of a link, and the device operation parameter is used to indicate an operation condition of a device.

Optionally, in this embodiment, when the BMC is powered on, the BMC may acquire information (i.e. an equipment operating parameter) and a link state (i.e. a link connection parameter) of each PCIe device from the BIOS, after AC (alternating current) power-on, the BMC may record a target connection parameter when the first power-on is performed, and compare the target connection parameter with the target connection parameter when the first power-on is performed later, so as to determine whether a PCIe fault occurs, and the PCIe device has no link or link status error.
