Problems solved by technology

[0003] However, in some special occasions, the network interface reserved by the server cannot fully meet the needs of use. For example, the server itself does not have an onboard network card or the number of network ports is insufficient. In this case, it is generally necessary to expand the external network card.
[0004] However, for occasions where data transmission requirements are not high, choosing an external network card will undoubtedly increase the cost, and the server needs to be powered off and disassembled for installation, which will have a negative impact on the normal operation of the data center

Abstract

The present invention provides a switch, comprising: a first chip, the first chip converts the signal type of the received signal; a second chip, the second chip controls the exchange and sending and receiving of Ethernet signals; a Flash chip; an EEPROM chip USB interface and RJ45 interface; Wherein, described first chip connects Flash chip through SPI interface; Described first chip connects second chip; Described USB interface connects first chip; Described EEPROM chip connects second chip; The second chip is connected to the RJ45 interface. The invention can realize mutual conversion between USB signal and Ethernet signal, and has the basic function of switch at the same time. The server network interface can be flexibly expanded, and has the feature of hot plugging, and the use process does not affect the normal operation of the server.

Description

technical field [0001] The invention belongs to the technical field of switches, and in particular relates to a switch. Background technique [0002] With the development of network communication technology, the demand for big data transmission in data centers is also increasing, and switches play an important role as an indispensable node in the network data transmission link. Moreover, data terminals and transmission carriers are gradually diversifying, and the requirements for switches are becoming more diverse. At present, the most common one is an Ethernet switch, which is interconnected with server nodes through an optical interface or an electrical interface. [0003] However, in some special occasions, the network interface reserved by the server cannot fully meet the needs of use. For example, the server itself does not have an onboard network card or the number of network ports is insufficient. In this case, it is generally necessary to expand an external network ...
