GE IS420ESWAH3A Industrial Ethernet Switch with Eight 10/100Base-TX Copper RJ45 Ports for Real-time Industrial Control

The General Electric IS420ESWAH3A is an Industrial Ethernet (IONet) Switch engineered for real-time industrial control systems. It is designed to meet the demanding speed and functionality requirements of these environments through a set of specific hardware and performance features.

A key distinguishing hardware characteristic of the IS420ESWAH3A is its front-panel configuration, which features eight 10/100Base-TX copper RJ45 ports. Notably, this model is unique within the ESWA switch family as it is the only variant that does not include any fiber optic ports, setting it apart from its counterparts.

The switch's operational capability is heavily based on its packet buffering architecture. It is designed to handle continuous streams of multicast or broadcast packets. A critical operational note is that the switch can only buffer a single incoming stream at any given time. Any additional streams must be queued and buffered for later transmission. To ensure proper performance, it is recommended to use a configuration of one packet per port.

In terms of its core performance criteria, the IS420ESWAH3A is characterized by several key specifications, including inrush current and switch latency. Fundamentally, the switch is built on a store-and-forward architecture. This design provides high data integrity by receiving and completely checking each data packet before forwarding it, thereby offering confidence for the reliable transfer of large amounts of data in a critical control environment.
