Today i have managed to Drop a chinese 7608n-e2 NVR ceilling to the ground ( while the case is closed ) After booting up, everything went normal, but SADP tool can not see the device anymore. TX/RX led on the front panel is blinking ( not so often ) and i also see the led on the router . So the cable is seen. But as the device is set to DHCP, its not getting any ip adres, also cannot ping when setting static one20160208_014329.jpg20160208_014537.jpg20160208_014545.jpg

The cables, which are connecting the mainboard with the front panel, are connected good. and no parts are missing. What could be wrong?
I am sure the router , cable etc are OK. Before the accident the nvr was working good.
