ES42 Series Edge Switches

Installation and User Guide (05/05)

auto-cross (MDIX) operation under auto-negotiation mode. The ES42 series provides switching among four 10/100 auto-negotiating copper ports and two 100Mb fiber ports which may be SC, ST, MTRJ or LC multi-mode or single-mode. The ES42’s breadth of fiber options and well as temperature options provide many networking options and solutions in a very small footprint.

Two sets of LEDs to indicating the operating status of ports are mounted on the top and front (for extra viewing advantage while rack-mounted). For each port, there are Link and Activity (LK/ACT) LED’s on the top indicating that the media cables are connected correctly and showing, by blinking, when there is traffic. The LK/ACT LED’s are repeated on the front as 1 (port 1)…6 (port 6), whereas on the side as LA1…LA6 . There is another set of LEDs on the front for 10 or H and 100 or F, to indicate the data rate as well as a set to indicate duplex for ports 1 and 2 only. 10/100 indicates the speed for copper ports, whereas F/H indicates Full and Half duplex for fiber ports only.

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.
