[0022] In the above process, the steps of configuring the PCI Express Switch of the PCIE management line card on the master and slave management boards include multiple software operations, any one of which may cause the system to work abnormally
[0023] It can be seen from the above process that in order for the dual management system to work normally, the CPU processing system of the master and slave management boards must complete two configuration operations on the PCI Express Switch and the CPU processor system of the line card before establishing normal data communication , there are many steps, the operation is complicated, and it is easy to make mistakes, which makes it difficult to work normally

The present invention relates to an expanding device, a system and a configuration method for a PCIE channel, wherein, the device comprises three groups of input / output interfaces for the PCIE bus; a switch module provided with channels for upgoing and downgoing data, the first end of the switch module is connected with the interfaces of the first group respectively and the second end is switched and connected with the interfaces of the second group and the third group; a control module as well as a power drive module. The system adopts an expanding device for the PCIE channel and also comprises a CPU processing system, which is connected with the first group of input / output interfaces for the PCIE bus and also is connected with the control module to give control commands to control the operation of the control module. The method includes as following: after being electrified, a managing system decides whether the managing system is normally connected with the CPU processing system of the expanding system. If being connected normally, the managing system configures the CPU processing system of the expanding system of the PCIE channel and then works normally. The hardware of the present invention has simple structure, low cost, simple configuration flow and high work efficiency and reliability.
Description
technical field [0001] The present invention relates to a PCIE channel expansion device, a system and a configuration method thereof, in particular to a PCIE channel expansion device applicable to a dual management system, connecting each board and a master and a slave management board, and adopting the PCIE channel expansion A device channel expansion system and a configuration method thereof belong to the technical field of data communication. Background technique [0002] Peripheral Component Interconnect (hereinafter referred to as PCI) bus is a PC local bus standard launched in 1993. The PCI bus is a local bus that is not attached to a specific processor. From a structural point of view, PCI is a first-level bus inserted between the CPU and the original system bus. Specifically, a bridge circuit realizes the management of this layer, and realizes the interface between the upper and lower systems to coordinate data transmission. [0003] PCI Express (PCI Express, herei...
