LED keeps blinking red
The LED stays blinking red for a long time, indicating the Ethernet port is not connected. Verify the Ethernet connection.
LED keeps blinking green
The AP performs initialization after power on. During this period, the LED keeps blinking green and does not turn solid
until the initialization is completed. Note: If the blinking persists for an hour, it indicates the device initialization fails and
the device is faulty.
LED keeps blinking orange (Fit AP mode)
Sometimes the AP performs firmware upgrade after power on. During this period, the LED keeps blinking orange and
does not turn solid until the upgrade is completed. Note: Do not plug or unplug the power cord when the Status LED is
blinking as firmware update takes time. If the blinking persists for ten minutes, it indicates the device fails to complete
firmware upgrade and is faulty.
LED does not turn solid blue or blinking blue
After the system starts and the LED does not turn solid blue or blinking blue, probably because the AP has not established
a proper CAPWAP connection with the AC. Verify the AC is operational and configured properly.
