Default
Table 4-18 Indicators on the AirEngine 8761-X1
Silkscreen Name Color Status Description
- System indicator - Off The system is not running.
Green Steady on
  • The system is just powered on.
  • The system is starting after a reset.
  • The upper-layer system is starting.
Green Steady on after blinking once After the hardware reset is cleared and the software starts, the indicator blinks once. Then, the indicator is steady on until the bottom-layer system starts.
Green Slow blinking (0.5 Hz) The AP is running properly, the Ethernet connection is normal, and STAs are associated with the AP.
Green Slow blinking (0.2 Hz) The AP is running properly, the Ethernet connection is normal, and no STA is associated with the AP.
Green Blinking once every 0.25s (4 Hz)
  • The bottom-layer system is being started.
  • The software is being upgraded.
  • After the software is loaded and started, the AP requests to go online in Fit or cloud management mode. The indicator remains in this state till the AP successfully goes online.
Yellow (blinking red and green at the same time, causing color deviation) Blinking once every 0.25s (4 Hz)

Hold down the Default button for more than 6 seconds to restore the factory settings.

This function is supported in V200R024C00 and later versions.
Red Steady on The system is faulty.

Silkscreen Name Description
Default Reset button
  • For versions earlier than V200R024C00: If you press the button, the device resets. If you hold down the button for more than 6 seconds, the device restores the factory settings, switches to the Fit mode, and restarts.
  • For V200R024C00 and later versions: If you press the button, the device resets. If you hold down the button for more than 6 seconds, the indicator blinks yellow (blinking red and green fast at the same time, causing color deviation), and the device restores the factory settings, switches to the Fit mode, and restarts.
