The needs of Internet development promote the upgrading of network infrastructure equipment. In today's Internet era, servers are still the most important infrastructure equipment. Various Internet manufacturers can deploy different services on servers to meet the needs of different Internet users. The server is generally equipped with two different network channels, one is the external Internet channel, which is used to access the Internet for data communication and storage; the other is the local server management network channel, which is used to access to The server management personnel carry out the management and control of the server. This kind of channel generally has strict management requirements and is forbidden to go outside.

The above-mentioned server management network is generally based on the BMC (Baseboard Management Controller, Baseboard Management Controller) chip as the management core, and a modular architecture scheme that connects the RJ45 network port through several PHY (Port PhysicalLayer, port physical layer) chips. Among them, the DC-SCM (DataCenter-readySecureControlModule, data center-ready security control module) board is a management board commonly used in servers. The server's rear window location.

Existing module architecture scheme 1 is shown in Figure 1. There is a BMC chip on the DC-SCM board, and two MAC (MediaAccessControl, media access control) ports are connected to the BMC chip, and MAC1 is connected to PHY1, wherein PHY1 is used for network The converted PHY chip is then connected to the onboard RJ45-1 network port of the DC-SCM board. MAC2 is connected to PHY2, then connected to MDICONN (Medium DependentInterfaceconn, media-related interface/signal connector), and connected to the left ear plate at the front window of the server through a cable. There is another RJ45-2 network port on the ear plate.

Existing module architecture scheme 2 is shown in FIG. 2 , a single MAC1 on the BMC chip is connected to PHY1, and then connected to MDICONN0 (signal connector). When you need to use the RJ45 (Registered Jack-45) network port on the rear window of the server, connect to MDICONN1 through the MDI (Medium Dependent Interface, media-dependent interface) cable, and then connect to the RJ45-1 network port through the wiring on the DC-SCM board; When the front window RJ45 network port needs to be used, it is connected to the left ear plate through the MDI cable, and the left ear plate is connected to the RJ45-2 network port through MDICONN2, so that the front and rear management ports of the server can be switched and used.
