Red Lion 508FX2-ST
Product Name: N-Tron 500 Series 8-Port Industrial Ethernet Switch with ST Fiber
Introduction: This unmanaged industrial switch combines copper Fast Ethernet with multimode fiber ST ports for harsh environments. It provides plug-and-play switching for factory floors, utilities and process networks.
Detailed content
Technical Specifications:
- Model: 508FX2-ST
- Copper ports: 6 x 10/100Base-TX RJ45
- Fiber ports: 2 x 100Base-FX ST, multimode
- Fiber distance: up to 2 km
- Throughput: store-and-forward switching fabric rated for full 8-port wire speed
- Supply voltage: 10 to 30 V DC, redundant inputs
- Protection: IP20
- Mounting: DIN rail
- Operating temperature: -40 to 85 °C
- Housing: metal
Functional Features: Auto-negotiation, auto-MDIX, auto-duplex on copper, bi-color LEDs for link/speed/activity, redundant power inputs, industrial EMC and hazard-area compliance per product standards.
Material Composition: Metal enclosure, PCB with industrial-grade Ethernet PHYs, ST optical transceivers, RJ45 magnetics, redundant DC power filtering components.
Structural Features: Compact DIN-rail body, front ST fiber connectors, front RJ45 row, LED status array, spring/screw power terminals, fanless passive cooling.
Working Principle: Incoming Ethernet frames are received, checked and stored, then forwarded to the destination port based on MAC learning. Fiber ports extend the network over multimode optical cable with electrical isolation and longer distance than copper.
Application Scenarios: Industrial automation backbones, water/wastewater plants, factory VLAN edge switches, fiber uplinks between cabinets, outdoor enclosures with extended temperature demands.
Installation Requirements: Mount on a 35 mm DIN rail, use 12 or 24 V DC redundant power with proper fusing, insert ST fiber with correct polish and cleaning, keep bend radius within fiber specification, and ground the metal enclosure.
Usage Precautions: Do not exceed 30 V DC input, avoid unauthorized managed-configuration expectations because the unit is unmanaged, clean fiber ends before mating, verify port LED status after startup, and ensure ventilation around the metal case.
