Problems solved by technology

[0004] According to the above method, when the link between the card slot of the motherboard and the interface card is abnormal, it is necessary for technicians to manually replace the interface card on site and re-establish the link to determine whether the abnormality is caused by the motherboard or the interface card. An exception occurs, so the efficiency of locating the source of the exception (mainboard or interface card) is low

Embodiment Construction

[0059] The technical solutions in the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them.

[0060] The card slot, method and device for locating an abnormality source provided by the embodiments of the present invention may be applied to a scene where a link between a card slot and an interface card inserted into the card slot is abnormal. The card slot may be a card slot on a main board (also called a main control board); the interface card may be a network card, an optical fiber communication card, or an adapter card. When the interface card is inserted into the card slot, and the interface card and the card slot are electrically connected, the main board can implement the functions of the interface card through the interface card.

Abstract

The embodiment of the invention provides a card slot and an abnormal source positioning method and device and relates to the fields of communication and computing. Through the card slot and the abnormal source positioning method and device, abnormal source positioning efficiency can be improved. The card slot comprises a first sub-card slot and a second sub-card slot, wherein the first sub-card slot comprises n first connector sets, each first connector set comprises at least one first connector, the second sub-card slot comprises n second connector sets, each second connector set comprises atleast one second connector, each first connector uniquely corresponds to one second connector, and a switch is arranged between each first connector and the uniquely corresponding second connector.

Description

technical field [0001] The invention relates to the fields of communication and computing, in particular to a card slot, a method and a device for locating an abnormal source. Background technique [0002] PCIe (English: peripheral component interconnect express) is a high-performance, high-bandwidth serial communication interconnection standard. The link (English: lane) between the card slot and the interface card defined in PCIe is a full-duplex transmission mode, and each transmission direction is composed of a pair of differential signal lines, so a link is composed of 4 signal lines. After each link is physically connected, the link establishment starts. After the state negotiation is carried out through the link training state machine (English: link training and status state machine, LTSSM), if the link is successfully established, the LTSSM enters the L0 state ( That is, the normal state); if the link fails to be established, the LTSSM enters the repair state or the ...
