Abstract

The invention discloses a switch board card hot plug method, device and system of a switch and the switch. The method comprises the steps: detecting an in-place signal of a switch board card in a CPLDvia a processor; determining state information of the pluggable board card according to the in-place signal, wherein the state information comprises identity information and a plugging state, and theplugging state is plugging or removing; according to the state information, configuring drive communication between the processor and communication equipment in the pluggable board card, and configuring a communication port corresponding to the pluggable board card; according to the invention, wherein the CPLD for detecting the in-place condition of the switching board card inserted into the switch is arranged in the switch. The processor can exchange the in-place signals of the board card according to the CPLD, the state information of the switch board card which is plugged is determined according to the state information of the switch board card which is plugged, so that the communication setting of the switch board card which is plugged is correspondingly configured, the switch completes the plugging operation of the switch board card without power failure, the service is quickly recovered, the hot plugging function of the switch board card is realized, and user experience is improved.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a switch and a method, device and system for hot plugging of switch boards thereof. Background technique [0002] A switch is a network device used for electrical (optical) signal forwarding. It can provide an exclusive electrical signal path for any two network nodes connected to the switch. The most common switches are Ethernet switches. Other common ones are telephone voice switches, fiber optic switches, etc. [0003] There are several ports on the front panel of the switch that provide network access points. In recent years, with the continuous improvement of the bandwidth and capacity of switching chips, it is often necessary to arrange the front panel ports on different switching boards. Each switching board has a number of ports, and each switching board can be plugged and pulled independently. [0004] When a switch is deployed, one or several switching boards can...
