Problems solved by technology

The disadvantages of this approach are:
[0010] 1) The special identification of cables is inspected and confirmed by people, and it cannot be guaranteed to be 100% correct
[0011] 2) The cable coding cannot be normalized, and the risk of availability increases
[0012] 3) If there are more than three miniSAS cables in the design, the cable expandability is not good

Embodiment Construction

[0063] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0064] In the embodiment of the present invention, the detection signal is received through the cable; the first duty ratio is compared with the second duty ratio, or the first frequency is compared with the second frequency, wherein the first duty ratio is the pre-stored The original duty cycle of the detection signal, the first frequency is the original frequency of the detection signal stored in advance, and the second duty cycle is the actual duty cycle of the detection signal after it is transmitted through the cable , the second frequency is the actual frequency after the detection signal is transmitted through the cable; according to the comparison result and a preset line insertion judgment principle, determine the insertion status of the cable. In this way, it is possible to automatically and correctly detect ...

Abstract

A method and an apparatus for detecting a cable connection condition, wherein the method comprises: receiving a detection signal through a cable (301); comparing a first duty ratio with a second duty ratio, or comparing a first frequency with a second frequency, wherein the first duty ratio is a pre-stored original duty ratio of the detection signal, the first frequency is a pre-stored original frequency of the detection signal, the second duty ratio is an actual duty ratio of the detection signal after transmission through the cable, and the second frequency is an actual frequency of the detection signal after transmission through the cable (302); and according to a comparison result and a preset cable connection determination principle, determining the cable connection condition (303), and thereby implementing automatic and correct detection of the cable connection condition instead of manual distinguishing by identifying the cable manually.

Description

technical field [0001] The invention relates to the field of communication, in particular to a method and device for detecting cable insertion conditions. Background technique [0002] In server products, the connection between the single boards in the rack server is through soft cable connection to realize data interaction. Therefore, there are many cables, and it is easy to have stable plugging but wrong plugging, or unstable plugging. The problem. [0003] Many interfaces with the same function, such as Serial Attached SCSI (SmallComputerSystemInterface), SAS) or Serial Advanced Technology Attachment (SerialAdvancedTechnologyAttachment, SATA) have industry-wide small SAS interface (MiniSerialAttachedSCSI, miniSAS) connectors and The general-purpose miniSAS cable runs in parallel for a long period of time in the chassis. After the cable crosses many times, it is difficult to distinguish the corresponding relationship with the opposite end interface. This is likely to occu...
