The hardware for HIL404 cannot be switched on. The LED exists at the front side of the hardware doesn't light up. Power cable has been connected to the socket and the socket works perfectly fine as I have tested it already with other electrical appliances. The red power button has already been pressed (supposedly after that, the LED light up). When the ethernet cable is connected to the PC, the light also did not light up, indicating the power supply did not reach the HIL404. How to solve this issue and what could be the problem?
