Disabling password recovery capability
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 to reconfigure 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.

Configuring the exception handling method
You can configure the device to handle system exceptions in one of the following methods:
• reboot—Automatically reboots to recover from the error condition (on an 6602/HSR6602) or
automatically reboots the failed MPU to recover from the error condition (on an 6604, 6608, or
6616).
• maintain—Stays in the error condition so you can collect complete data, including error messages,
for diagnosis. With this method, you must manually reboot the device.
