IS420ESWBH3A 基于以太网传输数据的交换机，它采用共享总线型传输媒体方式的局域网

IONet 交换机是一种以太网交换机，主要用于安防监控领域。与普通交换机不同的是，IONet 交换机除了具备数据传输交换功能外，还具备 POE 供电功能。这项功能可以给网络摄像头、无线 AP 网络、电话等网络设备供电，从而让它们免去繁杂的电源布线。IONet 交换机的优势有：
– 技术先进：单使用一条网线就可以同时传输数据和供电，比使用多条线路来说更先进。
– 布线方便：由于布线方便不用额外电源布线，在中大型监控系统中可以极大的节省投资成本。
– 节省成本：从工程角度来说可以少请施工人员，少购买些线材之类的降低劳动成本和物料成本，还可以缩短项目工期，后期维护难度也得到简化。
– 安全性高：由于没有直接的强电电源及强电电路，提高了使用的安全性。

以太网IONet交换机是一种基于以太网传输数据的交换机，它采用共享总线型传输媒体方式的局域网。以太网交换机的结构是每个端口都直接与主机相连，并且一般都工作在全双工方式。交换机能同时连通许多对端口，使每一对相互通信的主机都能像独占通信媒体那样，进行无冲突地传输数据。

IONet交换机是GE Speedtronic Mark VIe燃气轮机控制系统的一部分，具有8个端口和10/100BASE-TX。它专为满足实时工业控制解决方案的需求而设计，是Mark VIe和VIeS安全控制系统中使用的所有IONet交换机所必需的。

IONet交换机采用DIN – 导轨安装模块，具有802.3、802.3U、802.x兼容性，支持10/100基础铜带自动协商全/半双工自动协商100 mbps。它具有FX – 上行链路端口HP – MDIX自动感应LED指示链路存在、活动、双工和速度端口的状态，并且每个LED有两种颜色。此外，IONet交换机还具有4k媒体访问控制(MAC)地址的最小256kb缓冲区，并具有LED指示电源状态的功能。

在安装IONet交换机时，需要将开关连接到配电板的28 V直流电。

The IONet switch is an Ethernet switch mainly used in the security monitoring field. Different from ordinary switches, IONet switches have POE power supply function in addition to data transmission and exchange function. This feature can power network devices such as webcams, wireless AP networks, and telephones, so that they do not have to deal with complicated power wiring. The benefits of IONet switches are:
– Advanced technology: A single network cable can transmit data and power at the same time, which is more advanced than using multiple lines.
– Easy wiring: Because of the convenience of wiring without additional power wiring, it can greatly save investment costs in medium and large monitoring systems.
– Cost saving: from the engineering point of view, it can reduce the labor cost and material cost by requiring less construction personnel and purchasing less wire, which can also shorten the project period and simplify the difficulty of maintenance in the later period.
– High safety: Since there is no direct strong power supply and strong current circuit, it improves the safety of use.

Ethernet IONet switch is a kind of Ethernet based data transfer switch, which adopts the shared bus transmission media mode of local area network. The structure of the Ethernet switch is that each port is directly connected to the host, and generally works in full-duplex mode. The switch can communicate with many pairs of ports at the same time, so that each pair of hosts communicating with each other can transmit data without conflict as if they were exclusive communication media.

The IONet switch is part of the GE Speedtronic Mark VIe gas turbine control system with 8 ports and 10/100BASE-TX. It is designed to meet the needs of real-time industrial control solutions and is required for all IONet switches used in the Mark VIe and VIeS security control system.

The IONet switch uses DIN-rail mounting modules with 802.3U, 802.3U, and 802.x compatibility, and supports 10/100 base copper strip auto-negotiation full/half-duplex auto-negotiation of 100 mbps. It has an FX-uplink port HP-MDIX automatic sensing LED indicating the status of link presence, activity, duplex, and speed ports, and each LED comes in two colors. In addition, the IONet switch has a minimum 256kb buffer for 4k Media Access control (MAC) addresses and features an LED to indicate power status.

When installing the IONet switch, you need to connect the switch to the 28 V DC of the power distribution board.
