Note that this is a one-time operation. It takes effect only at the first reboot after
resetting console authentication is selected. At the next reboot, console authentication
is required.
8) Start up and ignore configuration.
Select option 8. The system sets an Ignore flag to Flash memory and displays:
Flag set successfully.
Thus, empty configuration applies at reboot. The system removes the Ignore flag after its boot
is completed.
In case you forget the password, you may select this option to have the router boot with the
configuration file ignored. After accessing the system, you may change or delete the password.
Note that if not saved, the modified configuration cannot survive a reboot. To have the router
reboot with the new configuration, you must perform the save operation after completing the
configuration.
9) Boot ROM Operation Menu
Select option 9 to enter Boot ROM Download Menu as follows for upgrade, backup, or
recovery:
Boot ROM Download Menu:
1: Download Boot ROM with XModem
2: Download Extended Segment of Boot ROM with XModem
3: Restore Extended Segment of Boot ROM from FLASH
4: Backup Extended Segment of Boot ROM to FLASH
5: Exit to Main Menu
Enter your choice(1-5):
10) a: Ignore software check
When upgrading software, make sure that you are using the correct software version.
If the upgrade still fails and the system displays “invalid version” in this case, you can
use this option. It allows the system to upgrade software without checking the version
of extended Boot ROM image segment, Boot ROM image, and application image for
backward compatibility. This is a one-time operation, however; the router checks
version again at reboot.
11) b: Boot from Flash
12) c: Boot from the CF card
13) d: Exit and reboot
5.2.2 Upgrading Software Using Xmodem
