network. The "cut-through" technique permits collision fragment frames, which are a result of late collisions, to be forwarded--which add to the network traffic. There is no way to filter frames with a bad CRC (the entire frame must be present in order for CRC to be calculated). Since collisions and bad packets are more likely when traffic is heavy, store- and-forward switch technology enables more bandwidth to be available for good packets when the traffic load is greatest.

To minimize the possibility of dropping frames on congested ports, each Magnum ES42 Series Edge Switch dynamically allocates buffer space from 128KB memory pool, ensuring that heavily used ports receive very large buffer space for packet storage. (Many other switches have their packet buffer storage space divided evenly across all ports, resulting in a small, fixed number of packets to be stored per port. When the port buffer fills up, dropped packets result.) This dynamic buffer allocation provides the capability for the maximum resources of the Magnum ES42 Series unit to be applied to all

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.
