Problems solved by technology

[0013] It needs personnel to actively trigger through software under the BMC, and it is not easy for non-professionals to operate; when the NSCI is blocked, the BMC cannot be accessed. At this time, if you want to switch the NCSI line through the BMC, you need to enable a dedicated management network to access the BMC, or enter the OS, use Special tool to access BMC and further to switch NCSI lines

Embodiment Construction

[0027] According to the accompanying drawings of the description, the present invention is further described in conjunction with specific embodiments:

[0028] Such as figure 1 As shown, in this embodiment, the standard PCIe x8 gold finger is connected to the external standard network card end and the motherboard, and the standard PCIex8 Slot is corresponding to the motherboard end. It is a PCIe device presence detection pin. This pin is usually pulled up to a high level on the motherboard side, which is a logic "1"; when an external card is connected, it is automatically set to a low level and becomes a logic "0". ";

[0029] The NCSI switch is a data strobe for choosing one of two. In addition to the A / B / C three sets of data chains and the necessary power and ground pins, there is also a Select pin. Among them: A group of NCSI data is connected to the controller of the NCSI function— —BMC MAC module, group B is connected to the carrier board network card end, while group...

Abstract

The invention discloses a system for improving dual-network card NCSI management system switching efficiency. The system comprises an NCSI Switch; the NCSI Switch is an alternative data selector and comprises A, B and C groups of data chains; the A group of NCSI data is connected with a controller with an NCSI function, namely, a BMC MAC module; the B group of the data chains are connected to an onboard network card end; the C group of the data chains are connected with an external network card slot; the NCSI Switch further comprises a Select pin; and the Select pin is connected with an online detection pin of the external network card slot through a logic conversion circuit. According to the method, adaptive switching of NSCI management system lines is realized, so that the switching no longer depends on a conventional external manual active triggering mode, and the switching efficiency is improved; speaking from a project development stage, the software design difficulty is lowered and the manpower input is reduced; and seen from product operation and maintenance, the product error tolerance rate is increased, the operation difficulty of operation and maintenance personnel is lowered, and the product stability is enhanced.

Description

technical field [0001] The invention relates to the technical field of computer board design, in particular to a system and method for improving switching efficiency of a dual-network card NCSI management system. Background technique [0002] Server (Server) is different from general consumer electronic products, requiring extremely high reliability and stability. For this reason, a complete server system generally has a dedicated network connected to the BMC, so as to monitor the operating status of each module of the motherboard in real time, and take corresponding measures in time to ensure the normal operation of the system when there is an abnormality in the system. [0003] BMC generally communicates with the outside world through two network methods: [0004] Dedicated management network and shared management network. Dedicated management network usually requires an external PHY chip to form a complete management system with BMC internal MAC module, peripheral RJ45 ...
