31.1.1 General
This section provides a broad range of troubleshooting tips for your device.
None of the LEDs turn on.
Make sure that you have the power cord connected to the NXC and plugged in to an appropriate
power source. Make sure that you have both power cords connected to the NXC and plugged into
appropriate power sources. Make sure you have both of the NXC's power switches turned on. Make
sure you have the NXC 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 NXC from the LAN.
• Check the cable connection between the NXC and your computer or switch.
• Ping the NXC 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 NXC's.
• In the computer, click Start > Programs > Accessories and then Command Prompt. In the
Command Prompt window, type "ping" followed by the NXC's LAN IP address (192.168.1.1 is
the default) and then press [ENTER]. The NXC should reply.
• If you've forgotten the NXC'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 NXC 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 NXC'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.
