>>>>>型号:BC810 扩展带有通信接口 板载通信端口
【功能描述】
BC810主要由底板(TP857)和电源/逻辑板两部分组成。底板是CEX-Bus和外部电源的连接器所在的位置。它通过外壳的金属部件接地到din -导轨上。该板还携带外部电源投票二极管和保险丝。电源和逻辑板包括+3.3 V转换器、逻辑板、CEX-Bus互连驱动和互连电缆连接器。
BC810可与PM857、PM861A、PM862、PM863、PM864A、PM865、PM866、PM866A、PM867和PM891配套使用。
在两台BC810和主备CPU对联动的全冗余系统中，BC810支持在线更换CPU底板，不会影响CEX流量。如果需要更换BC810，所连接的CEX网段的流量将全部停止。
cex总线用于扩展带有通信接口单元的板载通信端口。也可以在cex总线上使用冗余通信接口。cex总线互连单元BC810用于将cex总线划分为不同的段，以提高其可用性。这提高了具有冗余通信接口的系统的可用性。

【英文介绍】
The BC810 is mainly composed of a baseboard (TP857) and a power/logic board. The backboard is where the connectors for the CEX-Bus and the external power supply are located. It is grounded to the DIN-rail through the metal parts of the housing. The board also carries an external power voting diode and fuse. Power and logic boards include + 3.3V converters, logic boards, CEX-Bus interconnect drivers, and interconnect cable connectors.
The BC810 can be used with PM857, PM861A, PM862, PM863, PM864A, PM865, PM866, PM866A, PM867 and PM891.
In two fully redundant systems where the active and standby cpus are interconnected, the CPU mainboard of the BC810 can be replaced online, which does not affect CEX traffic. If the BC810 needs to be replaced, all traffic on the CEX network segment connected to it stops.
The cex bus is used to extend an onboard communication port with a communication interface unit. Redundant communication interfaces can also be used on the cex bus. The cex bus interconnect unit BC810 is used to divide the cex bus into different segments to improve its availability. This improves the availability of systems with redundant communication interfaces.
