5.1.3 Redundancy criteria

冗余准则

A redundancy toggle between Primary and Secondary is forced when the self-test diagnosis reveals the following conditions:

当自建诊断显示以下情况时,强制在主(控制器)和备(控制器)之间发生冗余切换。

If the redundant link is interrupted, a redundancy toggle is initiated. The previous Primary remains in the “no operating system“ status. When the redundancy link is re-established, a reset must be initiated in the Secondary.

如果冗余链路断开,则启动冗余切换。之前的Primary仍然处于“无操作系统”状态。当冗余链路重新建立时,必须在从备(控制器)启动复位。

 

If the Ethernet interface for the redundancy link on the Secondary fails, no redundancy toggle is performed. When the Ethernet interface for the redundancy link on the Secondary operates again, a reset must be initiated in the Secondary. 

如果冗余链路的以太网接口故障,冗余切换不会执行。当备控制器上的冗余链路以太网接口再次运行时,必须从备控制器复位操作。
