devices. There is no software configuring to be done at installation or for maintenance, even for the LLL ports. The internal functions of both are described below.

Switching, Filtering and Forwarding

Each time a packet arrives on one of the switched ports, the decision is taken to either filter or to forward the packet. Packets whose source and destination addresses lie on the same port segment will be filtered, constraining them to one port and relieving the rest of the network from processing them. A packet whose destination address is on another port segment will be forwarded to the appropriate port, and will not be sent to the other ports where it is not needed. Packets needed for maintaining the operation of the network (such as occasional multi-cast packets) are forwarded to all ports. The Magnum ES42 Series Edge Switches operate in the store-and-forward switching mode, which eliminates bad packets and enables peak performance to be achieved when there is heavy traffic on the network.

Switching, Address Learning

The Magnum ES42 Series units have address table capacity of 2K node addresses, and are suitable for use in large networks. They are self-learning, so that as

ES42 specifications

The GarrettCom ES42 is a high-performance switch designed to meet the demanding requirements of industrial Ethernet applications. It is known for its rugged construction, reliability, and versatility in various settings, including transportation, automation, and utility operations. Built to withstand harsh environments, the ES42 excels in applications where standard networking devices would fail.

One of the primary features of the GarrettCom ES42 is its extensive selection of port configurations. It typically includes multiple 10/100/1000Base-T Ethernet ports, allowing for easy integration into existing networks. The switch also offers optional SFP (Small Form-factor Pluggable) slots, providing flexibility for fiber optic connections which is crucial for long-distance data transmission in industrial settings.

The ES42 employs advanced Layer 2 switching technologies that enhance network efficiency and performance. Its support for multiple VLANs (Virtual Local Area Networks) enables network segmentation, improving both security and traffic management. Quality of Service (QoS) features allow for prioritization of critical data traffic, ensuring that essential communications receive the resources they need for optimal performance.

Another significant characteristic is its built-in redundancy features. The ES42 supports a range of redundancy protocols such as RSTP (Rapid Spanning Tree Protocol) and STP (Spanning Tree Protocol), which minimize downtime and ensure continuous network availability. This is particularly important in industrial applications where even a brief interruption can lead to significant operational losses.

The GarrettCom ES42 is also designed to operate in extreme temperature conditions, with models available that can function in temperatures ranging from -40°C to +85°C. This ruggedness makes it suitable for outdoor deployments and environments with high levels of vibration and electromagnetic interference.

In terms of management capabilities, the ES42 offers a comprehensive range of options, including SNMP (Simple Network Management Protocol), which allows for remote monitoring and configuration. This feature is vital for operators managing multiple devices across vast industrial networks.

Overall, the GarrettCom ES42 combines reliability, flexibility, and robust performance, making it an ideal choice for organizations needing dependable networking solutions in challenging environments. Its extensive features and technologies ensure that it meets the needs of modern industrial applications while providing scalability for future growth.
