GE Multilin IS420ESWBH2A Ethernet/IONet Switch

Product Description.

The IS420ESWBH2A device is an unmanaged IONet/Industrial Ethernet switch designed by General Electric for use with Mark VIeS or Mark VIe safety control systems.

One of the key defining features of the differences between the five ESWB switches is the number of fibre optic ports on the switch; the

This switch has two 100Base-FX multimode fibre optic ports, regardless of the mode of LC connection the fibre optic ports have.

A special feature of the RJ45 connectors is that they can handle high stress and should be able to use up to 200 insertion/removal cycles.

Standard operation of the IS420ESWBH2A switch will centre on the ability to buffer multicast and broadcast packet streams.

There are multiple streams that will enter the switch and there is enough room to buffer one packet per port.

Note that multiple streams typically allow only one incoming stream to be buffered, and the remaining streams must be saved for later transmission.

Because of the need for high reliability when using the IS420ESWBH2A switch, several performance criteria should be considered during operation,

switch architecture, inrush current, and switch latency. The inrush current of the switch will provide a soft start, helping to limit the inrush current to less than two hundred per cent of the normal operating current.

The Industrial Ethernet Switch IS420ESWBH2A is part of the Mark VIe series designed by General Electric and features two 100Base-FX multimode ports.

The IS420ESWBH2A switch has an RJ45 connector that should have a maximum of 200 insertion/deletion cycles.

The IS420ESWBH2A has high-speed and feature-use capabilities, and to achieve these features, a 100 Mbps FX uplink port and 10/100 base copper ports with auto-negotiation are required.
