Moxa EDS-405A-MM-ST , 3 10/100BaseT(X) ports, 0 to 60 °C content_copy

The EDS-405A-MM-ST from Moxa is a compact, industrial-grade managed Ethernet switch designed for demanding applications in harsh environments. It features three RJ45 ports and two fiber ports, configured for connection with 10/100BaseT(X) and 100BaseFX (SC/ST, multimode). The integrated support for Turbo Ring and Turbo Chain enables a network recovery time of under 20 milliseconds, ensuring availability in critical installations. Additionally, RSTP and STP are supported to ensure seamless integration into existing standard redundancy concepts.

Applications
This switch is suitable for use in industrial automation networks, particularly in environments with high requirements for fail-safety and operational safety. The extended operating temperature range of -10 to 60 °C (standard model) makes it suitable for indoor use under moderate temperature conditions. The metal housing with IP30 protection offers protection against mechanical impacts and provides sufficient protection class for use in enclosed enclosures.

Functions and Equipment in Detail
The EDS-405A-MM-ST supports VLAN functionality according to IEEE 802.1Q, port-based VLANs, and GVRP to efficiently segment networks. QoS functions are based on IEEE 802.1p and TOS/DiffServ to ensure prioritized data transmission. IGMP Snooping enables efficient control of multicast data streams. Management is performed via web browser, CLI, Telnet, serial console, or Windows utilities, enabling flexible configuration and monitoring. The integrated support for EtherNet/IP, Modbus TCP, and PROFINET IO Device (depending on model) facilitates integration into existing automation systems.

Technology Explained Simply
The integrated redundancy protocols Turbo Ring and Turbo Chain ensure rapid network recovery after a failure, with up to 250 switches operable in a chain. Power supply is via 12/24/48 VDC (9.6 to 60 VDC) with redundant inputs, reverse polarity protection, and overcurrent protection, enhancing reliability in industrial applications. Time management functions include NTP/SNTP for all models, with IEEE 1588v2 available only in PTP models. Security functions include HTTPS, SSL, SSH, access control, Port Lock, and Broadcast Storm Protection to prevent unwanted network activities.

Compatibility and Accessories
The switch is designed for use in existing Ethernet networks and supports standard protocols such as SNMP v1/v2c/v3, Telnet, TFTP, DHCP, LLDP, Port Mirroring, RMON, and Syslog. The fiber ports enable connection over longer distances with 100BaseFX (SC/ST, multimode). Mounting is done via DIN rail or optionally via a wall mount. Certifications include UL 508, UL 60950-1, EN 62368-1, FCC, EN 55032/35, ATEX, EN 50121-4, NEMA TS2, and DNV, confirming suitability for various industrial application areas.

Mounting and Installation
Installation is via DIN rail, enabling quick and secure mounting in enclosures. An optional wall mount is available. Power supply is via an external DC power supply, supporting an input voltage of 9.6 to 60 VDC. Cabling is done via RJ45 and fiber cables, with automatic speed detection and Auto MDI/MDI-X simplifying configuration.

Operational Advantages
The EDS-405A-MM-ST offers high availability through fast network recovery, flexible management via various interfaces, and a robust design for industrial environments. The integrated alarm function via a relay output in case of power failure or port interruption enables proactive fault detection. The MTBF is up to 1,547,941 hours (Telcordia standard), highlighting the high reliability of the device. Dimensions are 53.6 x 135 x 105 mm, and weight ranges from 650 g to 820 g (model-dependent). Relative humidity of 5–95 % (non-condensing) is also specified.

Scope of Delivery
The scope of delivery includes the switch, an RJ45-to-DB9 cable, port covers, a quick start guide, and a warranty card. These components enable quick commissioning and maintenance of the device.
