Leave unconnected to CF-EW72 V2 yet. - configure 192.168.1.(2-254)/24 static ip address on your PC LAN - press and keep pressed RESET button on device - power the device by plugging PoE Injector (POE) <-> CF-EW72 V2 (LAN) cable - wait for about 10 seconds until wifi led stops blinking and release RESET button - navigate from your PC to http://192.168.1.1 and upload OpenWrt *-factory.bin firmware file - proceed until router starts blinking with wifi led again (flashing) and stops (rebooting to OpenWrt) MAC addresses as verified by OEM firmware: vendor OpenWrt address LAN lan\eth0 label WAN wan label + 1 2g phy0 label + 2 5g phy1 label + 3 The label MAC address was found in 0xe000. LEDs detailed: The only both visible and controllable indicator is blue:wlan LED. It is not bound by default to indicate activity of any wireless interfaces. Place (WAN->ANT) | Num | GPIO | LED name (LuCI) | Note -----------------|-----|----------------------------------------------------------------------------------------- power | 1 | | | POWER LED. Not controlled with GPIO. hidden_led_2 | 2 | 13 | blue:hidden_led_2 | This LED does not have proper hole in shell. wan | 3 | | | WAN LED. Not controlled with GPIO. hidden_led_4 | 4 | 16 | blue:hidden_led_4 | This LED does not have proper hole in shell. lan | 5 | | | LAN LED. Not controlled with GPIO. noconn_led_6 | 6 | | | Not controlled with GPIO, possibly not connected wlan | 7 | 15 | blue:wlan | WLAN LED. Wireless indicator. noconn_led_8 | 8 | | | Not controlled with GPIO, possibly not connected mt76-phy0 and mt76-phy1 leds also exist in OpenWrt, but do not exist on board. Signed-off-by: Alexey D.
