IS420ESWAH4A设备被描述为通用电气为其Mark VIe或Mark VIe安全控制系统制造的非管理型工业以太网10/100 Base交换机。该交换机有8个10/100Base-TX铜交换机，只有一个100Base-LX10单模光纤接口。光纤端口是所有ESWA交换机之间的主要区别。该交换机是为ESWA硬件形式设计的，允许它在安装时与259B2451BVP1或259B2451BVP2夹一起使用，当垂直安装交换机时使用BVP2夹，当平行安装交换机时使用BVP1夹。

当使用IS420ESWAH4A交换机时，需要以下特性来帮助实现功能和速度:

全/半双工自动协商

电源用LED

最小265 KB缓冲区，4k媒体访问地址

HP-MDIX auto-sensing

上述功能只是满足速度和功能需求所需的部分功能。更多的要求可以在GEI-100869 Mark VIe工业以太网/IONet交换机汇总表或GEH-6855 Mark VIe功能安全系统卷II指南中找到。GEH-6855手册中的信息从第85页开始。

如果使用IS420ESWAH4A交换机替换其他非管理型交换机，则使用已经存在的安装支架;支架可以是din导轨或面板安装支架。确定开关如何安装所需的所有信息，特别是面板安装，GEH-6855手册第二卷第90页有一个图表，可以使用。

The IS420ESWAH4A device is described as an unmanaged industrial Ethernet 10/100 Base switch manufactured by General Electric for their Mark VIe or Mark VIeS Safety control systems. This switch has eight 10/100Base-TX copper switches and only one 100Base-LX10 single-mode fiber port. The fiber port is the primary distinguishing feature between all of the ESWA switches. This switch was designed for the ESWA hardware form which allows for it to be used with the 259B2451BVP1 or 259B2451BVP2 clips when being mounted, the BVP2 clip is used when mounting the switch perpendicular to the rail and the BVP1 clip is used when mounting the switch parallel to the rail.

When using the IS420ESWAH4A switch the following features are needed to help with functionality and speed:

Full/half duplex auto-negotiation
LED for power
Minimum 265 KB buffer with 4k media access addresses
HP-MDIX auto-sensing

The above features are just some of the features needed when meeting the speed and functionality requirements. More requirements can be found in either the GEI-100869 Mark VIe Industrial Ethernet/IONet Switches Summary Sheet or the GEH-6855 Mark VIeS Functional Safety Systems Volume II guide. Information in the GEH-6855 manual starts on page eighty-five.

If the IS420ESWAH4A switch is being used to replace a different unmanaged switch the mounting brackets that already exist will be used; the brackets can be DIN-rail or panel mounting brackets. All information needed to determine how the switch will be mounted, especially panel mounted there is a diagram on page ninety of the second volume of the GEH-6855 manual that can be used.
