Handling upgrade failures
If an upgrade failure occurs, the switch operates using the original version.
Follow these steps to handle upgrade failure:
1. Check the connections of the physical ports. Reconnect ports that are not properly connected and
download the system software images again.
2. Check the HyperTerminal output for errors and typos. Correct errors and typos and download the
system software image again. The errors can be:
You have selected a baud rate of another value rather than 9600 bps to download the .app file
from the boot menu, but did not set to the corresponding baud rate on HyperTerminal.
You typed an incorrect IP address of the TFTP server or switch, filename, or TFTP work directory.
You typed an incorrect IP address of the FTP server or switch, filename, FTP username, password, or
FTP work directory.
3. Check that FTP or TFTP server software is running and has correct settings.
4. Check that the flash has enough memory to store the downloaded files.
5. Check that system software and Boot ROM are compatible. For the compatibility between the
system software and the Boot ROM, see the hardware and software compatibility matrix in
Release Notes.
6. Check that the Boot ROM image is applicable to the target cards.
