What to do if no LEDs light up when I power on my ZyXEL Communications Gateway?

If none of the LEDs turn on when you turn on the ZyXEL Communications Gateway, ensure the included power adapter or cord is correctly connected to both the ZyWALL and a working power source. If the issue remains, it may indicate a hardware problem, and you should contact your vendor.
