Failure patterns we regularly see on ControlLogix EtherNet/IP bridge module hardware like the 1756-EN2TR:
- Scrolling display / IP address display blank while the module still passes traffic
- Module drops all CIP connections under load and recovers only after a power cycle
- Ethernet port failure: no link LED, or link flapping with a known-good cable and switch port
- Solid red OK LED at power-up (module hardware fault) or module not seen in RSLinx
- Overheating when the module runs near its connection limit in a sealed enclosure
