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.
6.2 Dealing with Password Loss
Contact your sales agent if you lost the BootROM password or user password.
6.3 Dealing with Power System Failures
You can know whether the power system has failed by reading the POWER LED on the
front panel. If the power system is operating normally, the POWER LED is ON. If not,
check that:
z The switch power cord is correctly connected.
z The power source can work with the switch.
6.4 Dealing with Configuration System Failures
If the switch is operating normally after it is powered up, it displays the start-up
information on the console terminal. If the configuration system has failed, it displays
illegible characters or nothing at all.
