4. LED Indicators

• RDY (Green): Solid = Module operational; Blinking = Initialization/self‑test

• ERR (Red): Solid = Hardware/config fault; Blinking = Minor alarm

• STS1/FX1 ACT (Green): Channel 1 link/activity

• STS2/FX2 ACT (Green): Channel 2 link/activity

5. Installation

1. ESD protection: Wear anti‑static wristband before handling.

2. Power off: Disconnect rack power before insertion/removal.

3. Insert module: Align with empty Quantum slot, push firmly, tighten screw.

4. Connect cables:

   • Fiber: LC connectors (Tx ↔ Rx between devices)

   • Copper: RJ45 to switch/PLC/IO

5. Cable management: Avoid sharp bends; secure cables to prevent tension.

6. Power on: Restore power; verify RDY LED solid green.

6. Configuration

Software

• Compatible with EcoStruxure Control Expert 14.0+ (Unity Pro)

• No programming required for basic conversion; set network parameters in hardware config.

Network Settings

• Set IP, subnet mask, gateway for copper ports (if using Modbus TCP).

• Enable RIO fiber link in Quantum CPU configuration.

• Configure redundancy (RSTP) if required.

7. Operation

• Normal: RDY solid green; ACT LEDs blink on data transfer.

• Fiber link: Tx/Rx must be crossed between two modules.

• Redundancy: Automatically switches to backup fiber link on primary failure.

• Hot swap: Replace module without stopping the system (same model).

8. Maintenance & Troubleshooting

Routine Maintenance

• Inspect cables/connectors monthly; clean fiber ends with lint‑free cloth.

• Check LED status; update firmware via Control Expert if needed.

• Conformal coating reduces cleaning frequency; avoid harsh chemicals.

Common Issues

• RDY off: Backplane power fault or poor contact → Reseat module, check power.

• ERR solid: Config mismatch or hardware damage → Verify config, replace module.

• No fiber link: Tx/Rx reversed, dirty connectors, or cable break → Check polarity, clean, replace cable.

• Copper port no link: Cable fault or speed mismatch → Replace cable, check auto‑negotiation.

9. Safety & Compliance

• Install/maintain only by qualified personnel.

• Disconnect power before servicing.

• Use only approved fiber/copper cables.

• Comply with local EMC and safety regulations.
