CORRECTIVE ACTION
Make sure that you have the included power adaptor or cord connected to the
ZyWALL and to an appropriate power source.
If the error persists, you may have a hardware problem. In this case, you should
contact your vendor.
CORRECTIVE ACTION
Check your Ethernet cable type and connections. Refer to the Quick Start Guide
for LAN connection instructions.
Make sure the computer's Ethernet adapter is installed and functioning properly.

the station.
Verify that the IP address and the subnet mask of the ZyWALL and the
computers are on the same subnet.
