Chapter 6 Maintenance and Troubleshooting

6.1 Software Loading Failure

If software loading fails, the system keeps running in original version. 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 procedure.
If the ports are properly connected, check the loading procedure information
displayed on the HyperTerminal for input errors. If there is any input error, restart
the loading procedure with correct input.
For example, when using XMODEM, verify that you have reset the baud rate of the
HyperTerminal to 9,600 bps after loading the software with a baud rate other than 9,600
bps; when using TFTP, verify that you have specified the correct server and switch IP
addresses, the correct name of the software to be loaded and the correct working path
of TFTP server; when using FTP, verify that you have specified the correct server and
switch IP addresses, the correct name of the software to be loaded and the correct
username and password.
If software loading fails but there are neither physical connection problems nor input
errors, please contact your agent for help. Missing Password
