总线接口通信模件FCI冗余安装2个冗余接口通信模件FCI.一个FCl运行为主方式。
另一个FCl运行为热备方式FCl自身具备诊测能力，当检测到主FCI故障时，自动切换到热备的FCl运行。
如果选择冗余FCI及冗余ModuleBus VO总线时，主FCl可以控制2条ModuleBus总线，当主FCl故障时，热备的FCI将同时切换接管2条ModuleBus总线。
Bus interface communication module FCI Redundancy Install two redundant interface communication modules FCI. One FCl runs in primary mode.
The other FCl runs in hot backup mode. The FCl has the detection capability and automatically switches to the hot standby FCl when the active FCI is faulty.
If redundant FCI and redundant ModuleBus VO buses are selected, the active FCl can control two ModuleBus buses. When the active FCl is faulty, the hot standby FCI takes over the two ModuleBus buses at the same time.
