Make sure that you have the power adaptor connected to the ZyWALL and plugged in to an
appropriate power source. Make sure the fuse is not burnt out (see the User’s Guide appendices for
details). Check all cable connections.
If the LEDs still do not turn on, you may have a hardware problem. In this case, you should contact
your local vendor.
