The EDS-405A-SS-SC-T from Moxa is a compact, managed Industrial Ethernet Switch with three 10/100BaseT(X) RJ45 ports and two 100BaseFX Single-Mode SC ports. It was specifically developed for industrial applications requiring reliable network communication, simple management, and high fault tolerance. The robust design enables use in demanding environments, such as those found in manufacturing automation, power supply, or transportation technology.

Applications
This switch is suitable for industrial networks where high availability and rapid recovery from network failures are critical. It is particularly suited for systems operating with EtherNet/IP, PROFINET, or Modbus TCP, as these protocols are supported out of the box. The integrated redundancy functions make it an appropriate component for ring or chain topologies, such as in production lines or building automation.

Functions and Features in Detail
The EDS-405A-SS-SC-T offers Turbo Ring and Turbo Chain technology, enabling recovery times of under 20 ms with up to 250 switches. These functions ensure high network availability, even in the event of individual link failures. Additionally, the switch supports RSTP/STP to manage redundant paths in the network. For efficient network structuring, features such as IGMP Snooping, QoS (IEEE 802.1p, TOS/DiffServ), port-based VLAN, and IEEE 802.1Q VLAN are available. VLAN registration is performed via GVRP. Management is possible through various interfaces: web browser, CLI (Command Line Interface), Telnet, serial console, Windows utility, or the ABC-01 module. The software MXstudio provides visual network analysis and management.

Technology Explained Simply
The two 100BaseFX Single-Mode SC ports enable fiber-optic connections with high reach, typically over several kilometers, making them ideal for connecting remote sites or avoiding electromagnetic interference. The RJ45 ports support Auto-Negotiation for speed and duplex mode (full-duplex/half-duplex) as well as Auto MDI/MDI-X, simplifying cabling. The bandwidth management function allows traffic control to prioritize critical applications. Port Mirroring and RMON support network diagnostics and monitoring. Alarms can be sent via E-Mail or relay to quickly detect faults.

Compatibility and Accessories
The switch is equipped with EtherNet/IP and PROFINET out of the box, making it suitable for integration into existing industrial control systems. Support for Modbus TCP extends compatibility with additional fieldbus systems. For management and diagnostics, MXstudio and the ABC-01 module are available, enabling centralized network management. Connections to other switches or devices are made via the RJ45 and SC ports, with the SC ports intended for fiber optic cables with single-mode optics.

Mounting and Installation
The switch is designed for mounting in standard 19-inch racks or on walls. The included mounting hardware (model-dependent) facilitates installation. Configuration is performed via the mentioned management interfaces, with the quick start guide and conformity documents included in the delivery to support setup.

Operational Advantages
Thanks to integrated redundancy functions and support for modern network protocols, the EDS-405A-SS-SC-T provides high operational reliability. Simple management via multiple interfaces and diagnostic functions such as Port Mirroring and RMON enable efficient network monitoring. Support for industrial protocols like EtherNet/IP and PROFINET simplifies integration into existing automation systems. The fiber optic ports ensure stable, interference-free connections over long distances.

Delivery Contents
The delivery includes 1x EDS-405A Switch (model variant according to order), a quick start guide, conformity documents, and mounting hardware (model-dependent).
