Abstract

The embodiment discloses a plug-in board, a switch employing the plug-in board and a switch design method. The switch comprises a middle plate and a plurality of plug-in boards adopting the same structure, wherein each plug-in board comprises two port exchange chips, an interconnection exchange chip, a port connector and a middle plate connector; the ports of the two port exchange chips are divided into external connection ports and interconnection ports, which are in the same quantity; the external connection ports are connected with the port connector; the interconnection ports are respectively connected with the interconnection exchange chip in each plug-in board; the interconnection ports and the ports of the exchange chips, which need to span over the plug-in board for connection, are respectively connected with the middle plate connector; and the middle plate connector is in plug-in connection with the middle plate provided with a connection circuit, so as to achieve connection between the interconnection ports and the interconnection exchange chips of different plug-in boards. The embodiment effectively improves the integration level of the plug-in board of the switch and reduces the consumption of the plug-in boards, thereby enabling the assembly density of the switch to be increased and further effectively reducing the size of the switch.

Description

technical field [0001] The invention relates to network equipment, more specifically, to a plug-in board, a switch with the plug-in board and a design method for the switch. Background technique [0002] As an important network device, a switch is used to forward electrical signals in a link. [0003] Due to the limited ports provided by the switch chip, which is one of the core components of the switch, the design scheme of large switches is generally to cascade multiple switch chips according to a certain topology, so as to achieve the purpose of expanding the number of ports. [0004] In the prior art, in order to realize the cascading and application of multiple switching chips, the technical solution adopted is to modularize each functional component, divide it into a variety of circuit boards with their own modules according to different functions, and divide each circuit board The board is designed as the physical form of the plug-in board; then, the purpose of expan...
