Chapter 6 Maintenance and Troubleshooting

6.1 Dealing with Loading Failures

If software loading fails, the system operates with the original version.

To address the failure cause, take these steps:

1) Check that the physical ports are correctly and securely connected. If they are not,

reconnect them correctly and restart loading.

2) Check information about the loading procedures for input errors on the

HyperTerminal.

z

If XModem is used, check that you have reset the baud rate of the HyperTerminal
to 9600 bps after loading the software with another baud rate.

z

If TFTP is used, check that you have correctly specified the TFTP parameters:
server and switch IP addresses; name of the software to be loaded; and path for
the TFTP server to operate on program files.

z

If FTP is used, check that you have correctly specified the FTP parameters: server
and switch IP addresses; name of the software to be loaded; and username and
password.

3) Contact your sales agent for help if you cannot address the problem after taking

the preceding two steps.
