IS420ESWBH3A GE 工业以太网交换机

产品说明

工业以太网交换机IS420ESWBH3A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。

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。

IS420ESWBH3A开关可以多种方式安装，开关可以平行或垂直安装在d in导轨上，如果需要，也可以安装在面板上。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。

Product Description

Industrial Ethernet Switch IS420ESWBH3A is part of the Mark VIe Safety Control System designed by General Electric. This switch does not have any fiber ports but has sixteen copper ports, the copper ports are 10/100Base-TX RJ45 ports. The primary operation of the switch is to perform as a level one Ethernet switch which will center on the capability to buffer multicast and broadcast packets. There should be enough space to allow for the buffer of one packet per port; if multiple incoming streams are being sent to the switch, it can only accept one incoming stream out of the multiple streams and will buffer the remaining streams for later transmission.

There are LED indicators on the IS420ESWBH3A switch. There is a power LED and the remaining LEDs are activity and link functions. When the link LED is solid yellow it indicates that a 10 MB link is being used and when solid green a 100 MB link is being used, and no LED light indicates that there is no link. The colors for the activity LED are also green and yellow but they will flash, when the LED flashes green it indicates that the activity is at full duplex and when flashing yellow the activity is at half duplex.

The IS420ESWBH3A switch can be mounted in a variety of ways, the switch can be DIN-rail mounted in a parallel or perpendicular application and also has the possibility to be panel mounted if needed. Please note that when the switch is DIN-rail mounted there are different clips needed which are the 259B2451BVP1 and 259B2451BVP4 clips.
