Installation and User Guide (05/05)

nodes are added or removed or moved from one segment to another, the ES42- Series switch automatically keeps up with node locations.

An address-aging algorithm causes least-used addresses to fall out in favor of new frequently-used addresses. To reset the address buffer, cycle power down-and-up.

4.2 Auto-cross (MDIX), Auto-negotiation and Speed-sensing

The RJ-45 ports support auto-cross (MDI or MDIX) in the auto-negotiation mode according to the IEEE 802.3u standard. No crossover cables are needed on RJ-45 port, when connecting the ES42 to other unmanaged switches, legacy hubs, managed switches, media-converter etc. Please note that there can be conditions with managed switches where the switch manager fixes the port settings via software, and the result of the auto-negotiation is changed in the managed switch by the manager commands. In such cases, the 10/100 speed or the F/H mode may be affected, but auto-cross in the ES42 will still work. The auto-cross function cannot be disabled.

When an RJ-45 cable connection is made, and each time LINK is enabled, auto-negotiation takes place (except for legacy products, which do not have auto- negotiation and which go to the default state accordingly). The Magnum ES42 Switch advertises its capability for 10 or 100 Mbps speed and F/H duplex mode, and the device

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.
