Handling software upgrade failures
If a software upgrade fails, the system runs the old software version. To handle a software failure:
1. Check the physical ports for a loose or incorrect connection.
2. If you are using the console port for file transfer, check the HyperTerminal settings (including the
baud rate and data bits) for any wrong setting.
3. Check the file transfer settings:
 If XMODEM is used, you must set the same baud rate for the terminal as for the console port.
 If TFTP is used, you must enter the same server IP addresses, file name, and working directory as
set on the TFTP server.
 If FTP is used, you must enter the same FTP server IP address, source file name, working directory,
and FTP username and password as set on the FTP server.
4. Check the FTP or TFTP server for any incorrect setting.
5. Check that the storage device has sufficient space for the upgrade file.
6. If the message “Something is wrong with the file” appears, check the file for file corruption.
Dealing with password loss
CAUTION:
Dealing with console login password loss and user privilege level password loss from BootWare menus is
disruptive.
How to deal with console login password loss and user privilege level password loss depends on the
state of password recovery capability (see Figure 9 ). Password recovery capability controls console user
access to the device configuration and SDRAM from BootWare menus.
 If password recovery capability is enabled, a console user can access the device configuration
without authentication and configure new passwords.
 If password recovery capability is disabled, a console user must restore the factory-default
configuration before configuring new passwords. Restoring the factory-default configuration deletes
the main and backup next-startup configuration files.
To enhance system security, disable password recovery capability.
