Installation Manual

Maintaining Software

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

5.2.2Upgrading Software Using Xmodem

You can use the console port to upgrade software using Xmodem without the need of setting up a configuration environment.
