Recovering a Lost Password
An overview of recovering a lost password follows:
•
Enter the show version command to note the existing virtual configuration
register value.
•
Break to the bootstrap program prompt (ROM monitor).
•
Change the configuration register to 0x141 (ignore break; ignore NVRAM;
boot from ROM).
•
Enter the privileged mode in the system bootstrap program.
•
Enter the show configuration command to display the enable password.
•
Change the configuration register value back to its original setting.
To recover a lost password, follow this procedure:
1.
Attach an ASCII terminal to the BRIM console port (see Chapter 3, Section
3.5 Console Port Connections).
2.
Configure the terminal to operate at 9600 baud, 8 data bits, no parity, 2 stop
bits (or to whatever settings the CRBRIM-W/E is set).
A key to recovering a lost password is to set the configuration
register so that the NVRAM contents are ignored (0x0040),
allowing you to see your password.
NOTE
To recover a lost password if Break is disabled, you must have
physical access to the CRBRIM-W/E.
