GE IS220UCSAH1A工业以太网交换机是通用电气公司设计的Mark VIe安全控制系统的一部分。该交换机没有任何光纤端口，但有16个铜质端口，这些铜质端口是10/100Base-TX RJ45端口。该交换机的主要功能是作为一级以太网交换机，其核心功能是缓冲组播和广播数据包。应该有足够的空间来允许每个端口缓冲一个分组；如果有多个传入流被发送到交换机，它只能接受多个流中的一个传入流，并将缓冲其余的流以供以后传输。

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接功能指示灯。当链路指示灯呈稳定黄色时，表示正在使用10 MB的链路；当呈稳定绿色时，表示正在使用100 MB的链路；如果没有指示灯亮起，则表示没有链路。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，表示活动处于半双工状态。

开关可以多种方式安装，开关可以平行或垂直安装在din导轨上，如果需要，也可以安装在面板上。

The industrial Ethernet switch is part of the Mark VIe security control system designed by General Electric Company. This switch does not have any fiber optic ports, but has 16 copper ports, which are 10/100Base-TX RJ45 ports. The main function of this switch is to serve as a primary Ethernet switch, with its core function being to buffer multicast and broadcast data packets. There should be enough space to allow each port to buffer one packet; 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 switch. There is one power indicator, while the other indicators are activity and link function indicators. When the link indicator light is stable 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; If no indicator lights up, it means 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 switch can be installed in multiple ways, and can be installed parallel or vertically on the din rail. If necessary, it can also be installed on the panel.
