MOXA EDS-508A-MM-ST Managed Industrial Ethernet Switch

The MOXA EDS-508A-MM-ST is a rugged 8-port managed Ethernet switch designed for high-availability industrial networks requiring hybrid copper and fiber connectivity. This model features six Fast Ethernet RJ45 ports and two multi-mode 100BaseFX fiber ports with ST connectors, making it ideal for plants or infrastructure sites utilizing legacy ST fiber cabling alongside modern copper Ethernet .

Key Features and Product Highlights

• Hybrid Port Configuration: 6x 10/100BaseT(X) RJ45 ports (auto negotiation, full/half duplex, auto MDI/MDI-X) plus 2x 100BaseFX multi-mode fiber ports with ST connectors .

• Extended Fiber Distance: Multi-mode fiber ports support transmission distances up to 4 km (with 62.5/125 µm fiber) or 5 km (with 50/125 µm fiber) at 1310 nm wavelength .

• Industrial-Grade Reliability: Metal IP30 housing, DIN-rail mounting, redundant dual 12/24/48 VDC power inputs (9.6 to 60 VDC operating range), and -10°C to 60°C operating temperature .

• Fast Network Redundancy: Proprietary Turbo Ring and Turbo Chain technologies enable recovery times of less than 20 ms. Supports standards-based STP, RSTP, and MSTP for additional redundancy .

• Comprehensive Layer 2 Management: VLAN (802.1Q, port-based), QoS (802.1p), IGMP snooping/GMRP, port trunking (LACP), bandwidth management, and port mirroring .

• Advanced Security Features: IEEE 802.1X, HTTPS/SSL, SSH, TACACS+, RADIUS, and MAC-based port locking .

• Integrated I/O for Alarms: 2 alarm relay contacts (1 A @ 24 VDC) and 2 digital input channels (+13 to +30V for state 1) for integrating external sensors and alerts .

• Flexible Management: Configure via web browser, CLI, Telnet, serial console, or Windows utility. Supports SNMPv1/v2c/v3, RMON, and LLDP .
