Problems solved by technology

[0012] From the perspective of the whole process, the PCIE Switch mode switching operation is very cumbersome and takes a long time, which is not conducive to improving efficiency.
In some on-site environments, it is necessary to open the case to adjust the status of the Strap Pin. At the same time, it is very difficult to refresh the firmware, which brings great inconvenience to the use.

Embodiment Construction

[0051]The invention provides a method for switching the working mode of PCIE Switch with one key, which can realize one-key switching of the working mode through the UI button on the outside of the chassis or the relevant options under the BMC remote login interface; the Switch can be viewed through the UI indicator light on the panel or under the BMC interface model. Refresh the FW, restart the system, configure Strap Pin, etc. involved in the switching process are automatically performed by the BMC without human intervention.

[0052] as attached Figure 5 As shown, connect the Strap Pin to the pull-up resistor R1 and the pull-down resistor R2 through an analog switch or a Mos tube.

[0053] The analog switch is controlled by the BMC. You can choose to turn on the pull-up resistor R1, turn on the pull-down resistor R2, or turn off the high-impedance state of the pull-up resistor R1 and the pull-down resistor R2, which can meet the requirements of the three configuration sta...

Abstract

The invention provides a method for switching a PCIE Switch working mode through one key. According to the method, one-key switching of the working mode is achieved through a UI key at the outer sideof a case or related options of a BMC remote login interface, FW refreshing, system restarting, Strap Pin configuration and the like which are involved in the switching process are all automatically conducted by a BMC, manual interference is not needed, the method is convenient to operate, and the testing efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of server bus board design, in particular to a method for switching the working mode of a PCIE Switch with one key. Background technique [0002] With its high efficiency and strong versatility, PCIE is widely used as a common interface in the computer, server, and storage industries. As the demand for performance and functions continues to increase, HBA cards, HCA cards, GPU cards, network cards, OCP cards and various accelerator cards based on PCIE interfaces have emerged one after another. Limited by the number of CPU PCIE ports, the supported PCIE devices in the same system are limited. In order to solve the contradiction between the limited PCIE port of the CPU and the increasing function and performance requirements, the PCIE Switch for expanding the PCIE port was born. [0003] Currently, the common modes supported by PCIE Switch are Base Mode, VS Mode, NT Mode and Fabric Mode. Among them, Base Mode is a com...
