>>>>>型號(hào):BC810 擴(kuò)展帶有通信接口 板載通信端口

【功能描述】

BC810主要由底板(TP857)和電源/邏輯板兩部分組成。底板是CEX-Bus和外部電源的連接器所在的位置。它通過(guò)外殼的金屬部件接地到din -導(dǎo)軌上。該板還攜帶外部電源投票二極管和保險(xiǎn)絲。電源和邏輯板包括+3.3 V轉(zhuǎn)換器、邏輯板、CEX-Bus互連驅(qū)動(dòng)和互連電纜連接器。

BC810可與PM857、PM861A、PM862、PM863、PM864A、PM865、PM866、PM866A、PM867和PM891配套使用。

在兩臺(tái)BC810和主備CPU對(duì)聯(lián)動(dòng)的全冗余系統(tǒng)中，BC810支持在線更換CPU底板，不會(huì)影響CEX流量。如果需要更換BC810，所連接的CEX網(wǎng)段的流量將全部停止。

cex總線用于擴(kuò)展帶有通信接口單元的板載通信端口。也可以在cex總線上使用冗余通信接口。cex總線互連單元BC810用于將cex總線劃分為不同的段，以提高其可用性。這提高了具有冗余通信接口的系統(tǒng)的可用性。

【英文介紹】

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.
