In step 71, the monitoring module 13 determines whether a request related to one of the local area network serial function, multi-computer switching function and firmware update is received and generated by the operation detection module 11 of the launch notification. When the monitoring module 13 determines that the activation notification has been received (that is, in step 22 of the first detection subroutine, step 32 of the second detection subroutine, and step 32 of the second detection subroutine When any one of 34 has sent the activation notification to the monitoring module 13), the process proceeds to step 72; when the monitoring module 13 determines that the activation notification has not been received, the process proceeds to step 73.

In step 72 , the monitoring module 13 sets the physical connection enable bit to a high level, and proceeds to step 73 .

In step 73, the monitoring module 13 determines whether the physical connection enable bit is set to a high level.

In step 74, the monitoring module 13 periodically obtains 12 Obtain a total number of online logins of any one of the LAN serial function, the multi-computer switching function and the web page function currently being operated online. Among them, the monitoring module 13 first obtains the number of online logins corresponding to the operation of the LAN serial function, the number of online logins corresponding to the operation of the multi-computer switching function, and the number of online logins corresponding to the operation of the web page function, and sums up the corresponding operations The number of online logins of LAN serial function, multi-computer switching function and web page function to obtain the total number of online logins. In this embodiment, the monitoring module 13 obtains the current total online login number from the meeting management module 12 every 60 seconds, but it is not limited thereto.

When the monitoring module 13 determines that the total online login number is not equal to 0, the process returns to step 73; when the monitoring module 13 determines that the total online login number is equal to 0, the process proceeds to step 76.

In step 76, the monitoring module 13 sets the physical connection enable bit to a low level. The trigger condition for setting the physical connection enable bit to the low level is that the physical connection start bit is set to the low level when the bus online login number is equal to 0. Even if the number of online logins corresponding to the operation of the LAN serial function and the multi-computer switching function is 0, and even the number of online logins for operating the webpage function to update the firmware is 0, but as long as the online login related to the operation of other webpage functions If the number is not 0 (that is, the number of online logins counted according to the web page request sent in step 35 of the second detection subroutine is not 0), the entity connection enable bit will not be set to low quasi-position.

It is worth mentioning that in the following usage scenarios, it is necessary to ensure that the connection is not interrupted. Scenario 1: Install the operating system through the baseboard management control unit 1, Scenario 2: Use the local area network serial function, Scenario 3: Firmware such as BMC firmware, BIOS firmware and CPLD firmware are updated through the baseboard management control unit 1 . Since the operating system will be installed using the multi-computer switching function, the operation detection module 11 can detect the received web page request by detecting whether the received web page request is related to the multi-computer switching function Whether it may be related to the installation of the operating system, when a web page request related to the multi-computer switching function is detected, the activation notification is sent to the monitoring module 13, so that the monitoring module 13 activates the entity connection bit Set to a high level to ensure that the connection is not interrupted. Similarly, when the operation detection module 11 detects an intelligent platform management interface request related to the LAN serial function, it sends the activation notification to the monitoring module 13, so that the monitoring module 13 Set the physical connection start bit to a high level to ensure that the connection is not interrupted. And when the operation detection module 11 detects a webpage request related to updating firmware, it also sends the activation notification to the monitoring module 13, so that the monitoring module 13 sets the physical connection activation bit It is a high level to ensure that the connection is not interrupted. In this way, the requirement of uninterrupted connection in the above usage scenarios can be met.
