Complete these steps to recover your password:

1. Install a serial terminal or a PC with terminal emulation software on the PIX console port.

2. Verify that you have a connection with the PIX, and that characters are going from the terminal to the PIX, and from the PIX to the terminal.

Note: Because you are locked out, you only see a password prompt.

3. Immediately after you power on the PIX Firewall and the startup messages appear, send a BREAK character or press the ESC key. The monitor> prompt is displayed. If needed, type ? (question mark) to list the available commands.

4. Use the interface command to specify which interface the ping traffic should use. For floppiless PIXes with only two interfaces, the monitor command defaults to the inside interface.

5. Use the address command to specify the IP address of the PIX Firewall's interface.

6. Use the server command to specify the IP address of the remote TFTP server containing the PIX password recovery file.

7. Use the file command to specify the filename of the PIX password recovery file. For example, the 5.1 release uses a file named np51.bin.

8. If needed, enter the gateway command to specify the IP address of a router gateway through which the server is accessible.

9. If needed, use the ping command to verify accessibility. If this command fails, fix access to the server before continuing.

10. Use the tftp command to start the download.

11. As the password recovery file loads, this message is displayed:

12. Do you wish to erase the passwords? [yn] y

Passwords have been erased.

Note: If there are Telnet or console aaa authentication commands in version 6.2, the system also prompts to remove these.

13. The default Telnet password after this process is "cisco." There is no default enable password. Go into configuration mode and issue the passwd your_password command to change your Telnet password and the enable password your_enable_password command to create an enable password, and then save your configuration.

Thank you for the detailed description.

This was a problem at one of our custumers . And he informs me that he is using the procedure with a PIX installed with a failover!

So, no problem, needed only to disconnect the two PIXs.
