What do the different blink codes on Sophos access points mean?

In this guide, we explain what it means when the LEDs on a Sophos access point are flashing.

How is a reset made?

From time to time it is necessary to reset the access point. However, simply pressing the reset button is not enough. Depending on how long the reset button is pressed, the APX will either reboot or its configuration and image will be reset to factory defaults.

Restart with current build and configuration

  1. Press the reset key for up to 8 seconds.
  2. Release the reset key.
  3. The LED goes out and then lights up green. The AP is restarted.

Restart with current build and base configuration

  1. Press the reset button for 15-20 seconds.
  2. Release the reset key.
  3. The AP triggers a reboot and starts in the factory state.
  4. The access point must now be re-registered with the controller.
