Problem

Corrective Action

None of the LEDs 

turn on.

Make sure that you have the power cord connected to the ZyWALL and plugged in to an 

appropriate power source. Make sure you have the ZyWALL turned on. 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.

Cannot access 

the ZyWALL from 

the LAN.

Check the cable connection between the ZyWALL and your computer or switch. Refer to 

section

 3

 for details. 

Ping the ZyWALL from a LAN computer. Make sure your computer’s Ethernet card is 

installed and functioning properly. Also make sure that its IP address is in the same subnet as 

the ZyWALL’s.

In the computer, click 

Start

, 

(All) Programs

, 

Accessories

 and then 

Command Prompt

. In 

the 

Command Prompt

 window, type "ping" followed by the ZyWALL’s LAN IP address 

(192.168.1.1 is the default) and then press [ENTER]. The ZyWALL should reply.

If you’ve forgotten the ZyWALL’s password, use the 

RESET 

button. Press the button in for 

about 5 seconds (or until the 

PWR 

LED starts to blink), then release it. It returns the ZyWALL 

to the factory defaults (password is 1234, LAN IP address 192.168.1.1 etc.; see your User’s 

Guide for details).

If you’ve forgotten the ZyWALL’s IP address, you can use the commands through the 

console port to check it. Connect your computer to the 

CONSOLE 

port using a console 

cable. Your computer should have a terminal emulation communications program (such as 

HyperTerminal) set to VT100 terminal emulation, no parity, 8 data bits, 1 stop bit, no flow 

control and 115200 bps port speed. 

Cannot access 

the Internet.

Check the ZyWALL’s connection to the Ethernet jack with Internet access. Make sure the 

Internet gateway device (such as a DSL modem) is working properly. 

Check 

ge2

’s status in the 

Status

 screen. Use the installation setup wizard again and make 

sure that you enter the correct settings.
