If the LNK/ACT LED on your ZyXEL Communications Switch does not light up or flash when a device is connected, ensure that the connected device is powered on and properly connected to the switch. Also, check that the Ethernet cards on the connected devices are functioning correctly and that the network cable is not longer than 100 meters.
