Software Upgrade
Fault 1:
When upgrading the software using the TFTP approach, the system displays the
following message:
Loading... tftpGet: Error occurred while transferring the file.
An Error Occurred!:tftp transfer failed: error 0x43
download error!!!
Something is wrong. Please check.
Troubleshooting:
The symptom described above means that the new software version has not been
loaded. Fault isolation can be carried out from three aspects:
■
Check the TFTP server to see whether information can be sent. If not, the problem is
likely to result from an incorrectly-configured TFTP server IP address. In this case, make
sure that IP address of the TFTP server is the IP address of the network interface on the
PC, to which the Ethernet interface is connected. (For the procedure of selecting an
Ethernet interface for TFTP upgrade on 3Com 5000 Routers.
Run the
winipcfg
command and the system will prompt the IP address of the Ethernet
interface.
■
If Windows prompts “The system detected conflict between the IP address xxxx and
the system hardware address xxxx” in this case, it is very likely that the IP address of
the TFTP server was incorrectly assigned to the upgrading Ethernet interface on the
Router.
■
Check the TFTP server. If it prompts “The system cannot find the specified file”, ,
check whether the path set on the TFTP server and the file name (including the
extension) of the application software set on the Router are correct.
Upgrade the application software again after the problem is solved.
Fault 2:
When upgrading the software using the TFTP approach, and the system displays the
following message:
Loading...
NET download completed...
read len = [05567609]
The downloaded software is not a valid version.
Please download the correct version.
Press <Enter> key when ready.
Troubleshooting:
3Com 5000 Routers should be loaded with different application software versions. The
problem described above is likely to result from a mismatch between the application
software version and the router model. In this case, contact your agent to obtain the
correct software version and upgrade it again.
