Problems solved by technology

[0007] In communication equipment, the reliability of the micro switch is not very high. Under the mechanical impact formed during the insertion and removal of the single board or due to its own aging, it will gradually fail. The position micro switch will also be loose, and the software mistakenly thinks that the wrench is in the Hot swap state, resulting in an abnormal power-off of the AMC, which reduces the reliability of power supply control

Embodiment 1

[0026] An embodiment of the present invention provides a single board hot swap control method, which is used to improve the reliability of powering on and off a single board in a system.

[0027] An embodiment of the present invention provides a single-board hot-swap control method, which is applied to a communication system, and the single board of the communication system includes at least two microswitches, see Figure 4 , the single board hot swap control method includes the steps of:

[0028] S101. After detecting that the first micro switch is disconnected, detect whether the second micro switch is disconnected within a predetermined time;

[0029] S102. If it is detected that the second micro switch is not turned off within a predetermined time, then do not power off the single board.

[0030] In the embodiment of the present invention, if it is detected that the second micro switch is turned off within a predetermined time, the single board is powered off.

Abstract

The embodiment of the invention discloses a hot plug control method for a single board and communication equipment. At least two micro switches are arranged on the single board. The hot plug control method for the single board comprises the following steps of: when a first micro switch is detected to be switched off, detecting whether a second micro switch is switched off in a preset time or not;and if the second micro switch is detected not to be switched off in the preset time, not powering the single board off. In the embodiment of the invention, the at least two micro switches are arranged on the single board, the detection of whether the second micro switch is switched off in the preset time or not is continued after the first micro switch is detected to be switched off, and if the second micro switch is detected not to be switched off in the preset time, power-off is not performed, thereby avoiding the condition of abnormal power-off, caused by a failure of one switch, of the single board.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a single board hot swap control method and communication equipment. Background technique [0002] In the field of communication technology, especially in telecommunications, many devices are designed using ATCA (Advanced Telecom Computing Architecture) or MicroTCA (MicroTelecom Computing Architecture) standards. In the ATCA or MicroTCA system, AMC (Advanced Mezzanine Card, Advanced Mezzanine Card) single board will be used. see figure 1 , is a schematic diagram of the application of AMC in the ATCA system. Multiple AMCs are plugged into one ATCA board first, and then the ATCA board is connected to the backplane through the connector. see figure 2 , is a schematic diagram of the application of AMC in the MicroTCA system. Each AMC does not need to be connected to a single board first, but is connected to the system backplane through the slot of the MicroTCA chassi...
