In certain situations, the AP may exhibit patterns associated with the color red. Each pattern corresponds to a distinct symptom. This FAQ will explain those interpretations for you.

  • Steady red: The AP failed to boot up or is experiencing system failure.
  • Fast red blinking with on for 50 milliseconds and off for 50 milliseconds: The AP is undergoing firmware upgrade.
  • Slow red blinking with blink for 3 times and off for 3 seconds: The uplink of the AP is disconnected.
