【产品详情】

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。 该交换机没有任何光纤端口，但有 16 个铜端口，铜端口是 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，其核心是缓冲组播和广播数据包的能力。应该有足够的空间来允许每个端口缓冲一个数据包;如果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，并将缓冲剩余的流以供以后传输。

IS420ESWBH3A开关上有 LED 指示灯。有一个电源 LED，其余 LED 是活动和链接功能。当链路 LED 呈黄色常亮时，表示正在使用 10 MB 链路，当绿色常亮时表示正在使用 100 MB 链路，无 LED 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。

【英文介绍】

The industrial Ethernet switch IS420ESWBH3A is part of the Mark VIe security control system designed by General Electric. The switch does not have any fiber ports, but has 16 copper ports, which are 10/100Base-TX RJ45 ports. The primary operation of the switch is performed as a Tier 1 Ethernet switch, the core of which is the ability to buffer multicast and broadcast packets. There should be enough space to allow one packet buffering per port; If multiple incoming streams are sent to the switch, it can only accept one of the multiple incoming streams and will buffer the remaining streams for later transmission.

The IS420ESWBH3A switch has an LED indicator. There is a power LED and the rest of the leds are active and link functions. When the link LED is steady yellow, it means that the 10 MB link is in use, when the green is steady on, it means that the 100 MB link is in use, and no LED light means that there is no link. The color of the active LED is also green and yellow, but they will flash, when the LED flashes green, it means that the activity is in a full duplex state, and when it flashes yellow, the activity is in a half duplex state.
