The Moxa EDS-G512E-8PoE-4GSFP-T is a fully managed industrial Gigabit switch with 12 ports, specifically designed for use in demanding environments. It features 8 PoE/PoE+-capable RJ45 ports (10/100/1000BaseT(X)) and 4 SFP slots for fiber optic connections (100/1000BaseSFP), making it suitable for both copper and optical network connections. The switch is designed for extreme operating conditions, with an operating temperature range of -40 to 75 °C and humidity of 5 to 95 % (non-condensing), qualifying it for use in process automation, traffic control, rail infrastructure, power supply, and other critical industrial applications.

Applications

The switch is designed for industrial networks requiring high reliability, redundancy, and security. It is particularly suitable for environments with high mechanical and thermal stress, such as factories, railway stations, power plants, or public transport. Support for industrial protocols such as EtherNet/IP, Modbus TCP, and PROFINET IO Device enables integration into existing automation systems. The robust construction with a metal housing and IP30 protection ensures stable operation in indoor environments with increased dust or moisture exposure.

Features and Equipment in Detail

The switch offers extensive networking functions, including VLAN (IEEE 802.1Q, GVRP, port-based, up to 256 VLANs, VID 1–4094), QoS (IEEE 802.1p/1Q, TOS/DiffServ, 4 priority queues), IGMP Snooping v1/v2/v3, and GMRP. Support for Jumbo Frames (9.6 KB) increases transmission performance for large data packets. The MAC table contains 8 K entries, and the buffer is 4 Mbit, ensuring efficient data processing. The PoE function (IEEE 802.3af/at) delivers up to 36 W per port, with a total budget of 240 W. The recommended operating voltage is above 50 VDC to optimally utilize PoE power.

Technology Explained Simply

PoE technology (Power over Ethernet) enables power supply to network devices via the Ethernet cable, eliminating the need for separate power sources. This is particularly advantageous for IP cameras, access points, or industrial sensors installed in hard-to-reach locations. Redundancy protocols such as Turbo Ring, Turbo Chain, RSTP, MSTP, and STP ensure rapid network recovery in case of failures. Link Aggregation (IEEE 802.3ad) allows combining multiple physical connections into one logical link to increase bandwidth and availability. Integrated MRP support (Media Redundancy Protocol) is relevant for rail and energy applications.

Compatibility and Accessories

The switch is compatible with SFP modules for fiber optic connections. Support for industrial protocols such as EtherNet/IP, Modbus TCP, and PROFINET IO Device enables integration into existing automation systems. Management is performed via Web-GUI, CLI, Telnet, TFTP, or a USB console (Type B). Network management is supported by SNMPv1/v2c/v3, RMON, Syslog, and DHCP Server/Client (Option 66/67/82). Time synchronization is achieved via NTP/SNTP.

Mounting and Installation

The switch can be mounted on a DIN rail and optionally features a wall mounting bracket. The metal housing (IP30) protects against dust and light mechanical stress. Power supply is via two 4-pole screw terminals with an input range of 44–57 VDC (recommended 48 VDC). Maximum current draw is 5.3 A at 48 VDC, and maximum power consumption without PoE devices is 14.36 W. The power supply includes reverse polarity protection and overcurrent protection.

Operational Advantages

The switch offers high operational reliability through redundant network protocols and extensive security functions such as IEEE 802.1X, RADIUS, TACACS+, HTTPS, SSH, MAC/IP-ACL, Sticky MAC, and Broadcast Storm Protection. Integrated LED status indicators, including PoE LEDs, enable quick visual monitoring of operational status. A relay output (1 A @ 24 VDC) and a digital input provide additional control and monitoring options. The MTBF is 788,215 hours (Telcordia), indicating high reliability. The manufacturer's warranty covers 5 years.

Certifications

The switch complies with numerous international standards: safety according to UL 508 and EN 62368-1, EMC according to FCC and IEC 61000-4-3/4/5, rail applications according to EN 50121-4, energy applications according to IEC 61850-3 and IEEE 1613, transportation applications according to NEMA TS2, and marine applications according to ABS, DNV, LR, and NK.
