to the ZyWALL and plugged in to an appropriate power source.
If the error persists, you may have a hardware problem. In this case,
you should contact your vendor.

ZyWALL from
the LAN.
Check your Ethernet cable type and connections. Refer to the
Rear
Panel and Connections
section for details.
Make sure your NIC (Network Interface Card) is installed and
functioning properly.
Cannot ping
any computer
on the LAN.
If all of the 10/100M LAN LEDs are off, check the cables between the
ZyWALL and your computer or hub.
Verify that the IP address and the subnet mask of the ZyWALL and
the computers are on the same subnet.
The WAN IP is provided after the ISP verifies the MAC address, host
name or user ID.

corresponding fields.

the
Wizard Setup
section in the User’s Guide) in the
System Name
field in the first screen of the
