Troubleshooting Software Loading Failure

If software loading fails, the system runs the old version of the software. In this case, check if the
physical ports are properly connected.
If the ports are not properly connected, reconnect them correctly and restart the loading process.
If the ports are properly connected, check the loading process information displayed on
HyperTerminal for input errors. In case of any input errors, restart the loading process with correct
inputs.
Input errors include:
A baud rate other than 9600 bps selected for BootWare loading using XMODEM.
An improper baud rate setting in HyperTerminal.
A wrong IP address, file name, or TFTP Server work path specified for software loading using
TFTP.
A wrong IP address, file name, username, or password specified for software loading using FTP.
If the case cannot be located, contact your local dealer for help.

Troubleshooting the Power System

For the WX3024, you can check whether the power system of the device has failed by viewing the RPS
LED and PWR LED on the front panel; for the WX3010 and WX3008, you can check whether the power
system of the device has failed by viewing the PWR LED on the front panel. When the power supply
functions normally, the RPS LED stays on or the PWR LED is blinking green. If the RPS LED is off or the
PWR LED is solid red, check whether:
The device power cable is properly connected;
The power input to the device meets the requirements.

Troubleshooting the Configuration System

If the device is operational upon power-on, the configuration terminal displays the boot information;
otherwise, you may see nothing or illegible characters on the configuration terminal.
No display on the terminal
If there is no output information after the device is powered on, check whether:
The power supply is normal;
The console cable is properly connected.
If the cause cannot be located in the steps above, check whether:
The console cable is in good condition.
Terminal settings are correct.
