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 31). 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.

Dealing with console login password loss

To set a new password if you forget the console login password:

1. If the password recovery capability is enabled, select 6 from the BootWare menu to start the system without loading the system configuration.

The following information appears:

Flag Set Success.

1. If the password recovery capability is disabled, select 5 from the BootWare menu to start the system with the factory default configuration.

The following information appears:

Because the password recovery capability is disabled, this operation can cause the configuration files to be deleted, and the system will start up with factory defaults. Are you sure to continue? [Y/N]Y Setting...Done.

1. When the BootWare menu appears again, select 0 to reboot the device.

The following information appears:

System start booting...

When you start the system without loading the system configuration, follow these steps to set a new login password:

1. After reboot, copy the configuration file to the PC through TFTP or FTP, and modify the configuration file in the text editor. Delete the password from the configuration file.
2. Copy the configuration file to the device to replace the original configuration file.
3. Set the next-startup configuration file.

<HP>system-view
<HP>startup saved-configuration startup.cfg
Please wait ...
... Done! 

1. Restart the device, and set a new password.

<HP>system-view
[HP]user-interface aux 0
[HP-ui-aux0]authentication-mode password
[HP-ui-aux0]set authentication password cipher 123456 

1. Save the new configuration by using the save command.

<HP> save 

Dealing with user privilege level password loss

1. Select 8 from the BootWare menu to clear the user privilege level password.

This operation takes effect at next reboot only. The user privilege level password is restored at a second reboot.

1. Reboot the device and you can directly enter system view.

Software loading failure

If software loading fails, the system runs previous software version. To troubleshoot the software loading failure:

• Verify that the physical ports are correctly connected. If the cable of any port is not connected, re-connect the cable to the port, and make sure the physical connection is correct. Load the software again.
• Check for errors in the software loading process displayed on the HyperTerminal. If errors exist, correct them, and load the software again.

For example, the software loading failures might occur in the following situations:

• When you use XMODEM to load software, you select a baud rate other than 9600 bps, but you have not reset the baud rate for the HyperTerminal.
• When you use TFTP to load software, you entered an incorrect IP address, software name, or TFTP serve path.
• When you use FTP to load software, you entered an incorrect IP address, software name, username, or password.

If software loading has failed even if the physical connections are in good condition and the software loading process does not have any input errors, contact HP Support.
