工业以太网交换机IS420ESWBH3A是通用电气设计的Mark VIe安全控制系统的一部分。 此交换机没有任何光纤端口，但有 16 个铜缆端口，铜质端口为 10/100Base-TX RJ45 端口。交换机的主要操作是作为一级以太网交换机执行，该交换机将以缓冲组播和广播数据包的能力为中心。应该有足够的空间来允许每个端口一个数据包的缓冲区;如果将多个传入流发送到交换机，它只能接受多个流中的一个传入流，并将缓冲剩余的流以供以后传输。

IS420ESWBH3A开关上有 LED 指示灯。有一个电源指示灯，其余指示灯是活动和链路功能。当链路 LED 呈黄色常亮时，表示正在使用 10 MB 链路，当稳定绿色时，表示正在使用 100 MB 链路，并且没有 LED 指示灯表示没有链路。活动 LED 的颜色也是绿色和黄色，但它们会闪烁，当 LED 闪烁绿色时，表示活动处于全双工状态，当闪烁黄色时，活动处于半双工状态。
IS420ESWBH3A开关可以以多种方式安装，开关可以DIN导轨安装在平行或垂直应用中，如果需要，也可以进行面板安装。请注意，当开关安装在DIN导轨上时，需要不同的夹子，即259B2451BVP1和259B2451BVP4夹子。

The industrial Ethernet switch IS420ESWBH3A is part of the Mark VIe security control system designed by General Electric. This switch does not have any fiber optic ports, but has 16 copper ports, with copper ports being 10/100Base-TX RJ45 ports. The main operation of the switch is to act as a primary Ethernet switch, which will center around the ability to buffer multicast and broadcast data packets. There should be enough space to allow a buffer of one packet per port; If multiple incoming streams are sent to the switch, it can only accept one of the multiple streams and buffer the remaining streams for future transmission.

There is an LED indicator light on the IS420ESWBH3A switch. There is one power indicator, while the other indicators are for activity and link functionality. When the link LED is constantly yellow, it indicates that a 10 MB link is being used. When it is stable green, it indicates that a 100 MB link is being used, and no LED indicates that there is no link. The colors of the activity LED are also green and yellow, but they will flash. When the LED flashes green, it indicates that the activity is in full duplex state, and when it flashes yellow, it indicates that the activity is in half duplex state.

The IS420ESWBH3A switch can be installed in various ways, and the switch can be installed with DIN rails in parallel or vertical applications. If necessary, panel installation can also be carried out. Please note that when the switch is installed on a DIN rail, different clips are required, namely 259B2451BVP1 and 259B2451BVP4 clips.
