LED Indicators & Status Feedback

- PON Signal Strength:

- All LEDs OFF: Booting up

1× red: Signal too low (< –28 dB)

1× white: Signal low (≥ –28 dB)

2× white: Good (≥ –25 dB)

3× white: Strong (≥ –11 dB)

1× red + 2× white: Signal too strong (≥ –8 dB)

3× red: No signal

Red flashes alternated with strong signal: No ONU authority 

Ethernet Port: Steady white indicates link-up; blinking signals activity; off signifies no connection. 

Power LED: Solid white confirms power status.
