Switch and network computer room for placing the switch

Abstract

The embodiment discloses a switch and a network computer room for placing the switch. The switch comprises a cabinet, a middle plate and a plurality of plug-in cards, wherein each plug-in card includes two port switch chip, one internal connection switch chip, a port connector, a middle plate connector and a guide rail, wherein the ports of the port switch chip are divided into the same number of external connection ports and inner connection ports; the external connection ports are connected with the port connector; the internal connection ports are respectively connected with the internal connection switch chip in each plug-in card; the internal connection ports and the ports of the internal connection switch chips, which are connected across the plug-in cards, are respectively connected with the middle plate connector, so as to achieve connection between the internal connection ports and the internal connection switch chips of different plug-in cards through the middle plate connector; the cabinet includes guide rail slots with the same number of the plug-in cards; and the plug-in cards can be plugged in or pulled out by inserting or pulling the guide rail along the insertion hole of the guide rail slots. The embodiment can improve integrity degree and reduce number of the plug-in cards of the switch, thereby effectively reducing the switch size.

Description

technical field [0001] The present invention relates to network equipment, more specifically, to a switch and a network cabinet for placing 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 expanding the number of por...
