Nobelic video recorders have light indicators you can use to find out if the device receives power, as well as if it's connected to the network. These indicators are located at the front and back panel of these devices.
The front panel has the indicator labeled POWER. This LED is solid blue if the device receives power.
The Ethernet cable port located on the back panel has 2 indicators, which can help determine if the DVR is connected to the network. If these indicators are not lit up, please double-check the connection to the router and the integrity of the Ethernet cable used.
