Upgrading the Boot ROMs

For troubleshooting information, refer to the System Error Messages and Debug Command Reference publications of Cisco Systems, found on the CD-ROM accompanying the router. You can also access “Technical Assis- tance” at the World Wide Web URL http://www.cisco.com (Cisco Connection Online) for a list of frequently asked questions and other technical tips.

Upgrading the Boot ROMs

The Boot ROMs are not user upgradeable. Please contact your nearest HP field service representative for further information.

Recovering Lost Passwords

This section explains how to recover the following types of passwords:

■An enable secret password (a very secure, encrypted password)— Available on routers running Cisco IOS Release 10.3(2) or later.

■An enable password (a less secure, nonencrypted password)—Used when the enable secret password does not exist.

■A console password—Prevents unauthorized users from attempting to change the router configuration. When a console password is set, you must provide a password to log in to the console and access user EXEC mode.

The key to recovering a lost enable password is to set the configuration register so that the contents of NVRAM are ignored (0x142), which allows you to see the password. The enable secret password is encrypted and cannot be recovered; it must be replaced. The enable and console passwords might be encrypted or clear text.

Take the following steps to recover a lost password:

1.Plan for about one-half hour of system downtime. The password recovery procedure requires a system reload.

2.Connect a terminal to the console port on the rear panel of the router. Make sure the terminal is configured to operate at 9600 baud, 8 data bits, no parity, and 2 stop bits.
