In certain situations, the AP may alternate between amber and green blinks. However, the speed and frequency of these blinks can vary, and each has a distinct meaning. This FAQ will clarify those meanings for you.

  • Blinks between amber and green alternately with 300 milliseconds interval: The AP is booting up.
  • Blinks between amber and green alternately with 1 second interval: The AP is discovering the NCC.
  • Blinks between amber and green alternately 3 times and then turns solid green for 3 seconds: The AP is discovering an AC, or is managed by NCC but fails to connect with NCC, and is reconnecting with the NCC.
  • Blinks between amber and green alternately 2 times and then turns solid green for 3 seconds: The AP is managed by an AC, but the uplink is disconnected.
