Chapter 6 Maintenance and Troubleshooting
6.1 Software Loading Failure
If software loading fails, the system still runs the original version. In this case, check
whether the physical interfaces are properly connected:
If not, reconnect them correctly and restart the loading procedure.
If so, view the loading information displayed on the HyperTerminal to check for
input errors. If there is any input error, restart the loading procedure and ensure
the input correctness.
Common input errors include:
Fail to set the baud rate of the HyperTerminal to 9,600 bps when loading the
software at a baud rate of 9,600 bps through XMODEM.
Enter an incorrect IP address, software name, or path of the TFTP server when
using TFTP.
Enter an incorrect IP address, software name, username, or password when using
FTP.
If software loading fails when there are neither physical connection problems nor input
errors, please contact your agent for help.
6.2 Configuration System Failure
After the LS8M1WCMA0-OVS card is powered on and the system is normal, the
booting information will be displayed on the console terminal. If the configuration
system has any faults, illegible characters or nothing will be displayed on the console
terminal.
I. Troubleshooting when nothing is displayed
If nothing is displayed on the terminal after the LS8M1WCMA0-OVS card is powered
on, please check whether:
The power supply is normal.
The console cable is properly connected.
If the above-mentioned items ruled out, the problem may lie in the console cable or the
settings of the terminal (such as HyperTerminal) parameters. Please perform the
corresponding check.
