Embodiment Construction

[0017] The design method of a PCIEX16 compatible self-developed PCIE DAUGHTER CARD of the present invention is described in detail below.

[0018] A PCIEX16 compatible self-developed PCIE DAUGHTER CARD design method of the present invention requires a 10G external plug-in card at the optical port to realize the function of three-network integration on the main board of the server, that is, the data transmission function must be realized first, and then the data transmission function must be realized. IP binding between intranet and data extranet. At the same time, in order to support the management function, there needs to be a dedicated NCSI data channel between the onboard BMC and the external 10G network card for management.

[0019] The self-developed 10G add-in card adopts the standard PCIEX8 data signal line design. At the same time, the data line managed by NCSI is an additional data signal line after the X8 data for NSCI use. Therefore, the design of this card will h...

Abstract

The invention provides a PCIEX16(Peripheral Component Interconnect Express)-compatible independent research PCIE DAUGHTER CARD design method, which is characterized by comprising a signal wire switching method and a switching method between Power and Standby electricity as well as between Power and Core electricity. A signal judgment mechanism is used for judging differences between unavailable slots, signal wires are switched by a logic switching unit; and a standbyPower power supply mode which adopts a PCIeX8+PCIex1 slot and a corePower power supply mode which only adopts a PCIex16 slot are switched on one card. Compared with the prior art, the design method disclosed by the invention is characterized in that people can apply a network card into all server products, the network card can be used as a common network card and also can be used as a special network card, which has a management function, of a mainboard.

Description

technical field [0001] The invention relates to the field of computer communication, in particular to a design method of a PCIEX16 compatible self-developed PCIE DAUGHTER CARD. Background technique [0002] As the demand for products increases, we independently develop an external optical fiber 10G network card (this network card has a PCIe signal line of PCIeX8 and an additional NCSI signal line on the PCIeX1 slot) to realize network card and network card management functions. [0003] After repeated reasoning and verification, in the initial implementation plan, if the network card is directly inserted into the PCIeX16 slot by the customer, it will cause the PCIE data line on the motherboard PCIEX16 slot, the ground and the NCSI data line of the PCIEX1 golden finger of the network card design. Short circuit, causing electrical damage to the board. [0004] Therefore, after repeated thinking, research and formulate the difference between the slots to allow the network card...
