Table 2-98 Indicators on the AirEngine 5761-11

Silkscreen	Name	Color	Status	Description
-	System indicator	-	Off	The system is not running.
		White	Steady on	The system is just powered on. The system is starting after a reset. The upper-layer system is starting.
		White	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.
		White	Slow blinking (0.5 Hz)	The AP is running properly, the Ethernet connection is normal, and STAs are associated with the AP. This state is supported in V200R022C00 and later versions.
		White	Slow blinking (0.2 Hz)	The AP is running properly, and the Ethernet connection is normal. For V200R022C00 and later versions, this state also indicates that no STA is associated with the AP.
		White	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.
		Red (blinking red and white 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.

Table 2-99 Buttons on the AirEngine 5761-11

Silkscreen	Name	Description
Default	Reset button	For versions earlier than V200R022C00SPC100: Hold down the button for more than 3 seconds to restore the factory settings and restart the device. For versions from V200R022C00SPC100 to V200R023C10: 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 red and white fast at the same time (causing color deviation), and the device restores the factory settings, switches to the Fit mode, and restarts.
