CORRECTIVE ACTION
Make sure that you have the correct power adaptor connected to the Prestige, it
is plugged into an appropriate power source and the Prestige is 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.
Check the cable connection from your computer to the Prestige.
Make sure your computer's IP address is in the same subnet as the Prestige's
IP address (see Section 5.1 on page
Ping the Prestige from a computer on the LAN. Make sure your computer's
Ethernet adapter is installed and functioning properly. In the computer, click
Start, (All) Programs, Accessories and then Command Prompt. In the
Command Prompt window, type "ping" followed by the Prestige's LAN IP
address (192.168.1.1 is the default) and then press [ENTER]. The Prestige
should reply; otherwise see
If the Prestige's IP address has changed, then enter the new one as the URL.
Use Internet Explorer 6.0 and later or Netscape Navigator 7.0 and later with
JavaScript enabled.
Make sure you enter the password correctly (the field is case sensitive).
If you've forgotten the Prestige's password, use the RESET button. Press the
button in for about 10 seconds (or until the PWR/SYS LED starts to blink), then
release it. It returns the Prestige to the factory defaults (password is 1234, LAN
IP address 192.168.1.1 etc.; see your User's Guide for details).
