The invention discloses a redundant switch, which comprises a first power supply module, a second power supply module, a main switching board, a standby switching board, a redundant management moduleand a network port switching module, wherein the first power supply module and the second power supply module are separately connected with the main switching board, the standby switching board and the redundant management module; the redundancy management module comprises a micro-control unit and a logic device connected with the micro-control unit through an I/O port; the micro-control unit is connected with the main switching board and the standby switching board; the logic device is connected with the network port switching module; the main switching board and the standby switching board are separately connected with the network port switching module through network cables; the network port switching module provides a plurality of paths of network interfaces to the outside; the redundancy management module is externally connected with a change-over switch and an indicating lamp. According to the invention, when the master switching board fails, the redundancy management module controls the network port switching module to switch and connect the external network interface to the slave switching board, so that redundancy switching of the switching board is realized.

    本发明公开了一种冗余交换机,包括第一电源模块、第二电源模块、主交换板、备交换板、冗余管理模块和网口切换模块:第一电源模块和第二电源模块分别与主交换板、备交换板、冗余管理模块连接;所述冗余管理模块包括微控制单元及与其通过I/O口连接的逻辑器件,所述微控制单元分别与主交换板和备交换板连接,所述逻辑器件连接网口切换模块;主交换板和备交换板分别与网口切换模块通过网线连接;网口切换模块对外提供若干路网络接口;冗余管理模块对外连接切换开关和指示灯。本发明在主交换板故障时,冗余管理模块控制网口切换模块,将外部网络接口切换连接到从交换板,实现交换板的冗余切换。
