IS420ESWBH2A设备是由通用电气设计的非托管IONet/工业以太网交换机，用于Mark VIeS或Mark VIe安全控制系统。五个 ESWB 交换机之间差异的一个关键定义特征是交换机上的光纤端口数量;此交换机有两个 100Base-FX 多模光纤端口，无论哪种模式，光纤端口都具有 LC 型连接。RJ45连接器的一个特殊功能是它们能够处理大量应力，并且应该能够使用多达200次插入/拆卸循环。
IS420ESWBH2A交换机的标准操作将以缓冲组播和广播数据包流的能力为中心。有多个流将进入交换机，并且有足够的空间来缓冲每个端口的一个数据包，请注意，多个流通常只允许缓冲一个传入流，并且必须保存剩余的流以供以后传输。
由于使用IS420ESWBH2A开关时需要高可靠性，因此在工作期间应考虑几个性能标准、开关架构、浪涌电流和开关延迟。开关的浪涌电流将提供软启动，有助于将浪涌电流限制在正常工作电流的 200% 以下。

The IS420ESWBH2A device is an unmanaged IONet/Industrial Ethernet switch designed by General Electric for Mark VIeS or Mark VIe security control systems. A key defining feature of the difference between the five ESWB switches is the number of fiber optic ports on the switch; This switch has two 100Base-FX multimode fiber optic ports, and regardless of the mode, the fiber optic ports have LC type connections. A special feature of RJ45 connectors is that they can handle a large amount of stress and should be able to use up to 200 insertion/disassembly cycles.
The standard operation of the IS420ESWBH2A switch will revolve around the ability to buffer multicast and broadcast packet flows. Multiple streams will enter the switch and have sufficient space to buffer one packet per port. Please note that multiple streams typically only allow buffering of one incoming stream and must save the remaining streams for future transmission.
Due to the high reliability required when using the IS420ESWBH2A switch, several performance standards, switch architecture, surge current, and switch delay should be considered during operation. The surge current of the switch will provide soft start, which helps to limit the surge current to below 200% of the normal operating current.
