Check the cable connection. If the ETHERNET LEDs are visible, the LED at the top left
should light up green. Otherwise, there must be a network connection error or a power
issue.

If you are using several VLANs (Virtual Local Area Networks), check that the device is
on the same VLAN as your computer.

Connect your computer directly to the device using a direct cable. The device
automatically takes an IP address (format 169.254.x.y). Change the IP address of your
computer to this type by using a network mask 255.255.0.0.
