Follow these steps to reset the password that allows the Admin user access to the ACE module:
Connect to the console port of the ACE module in the Catalyst 6500 series switch.
Reboot the ACE module from the Catalyst 6500 series CLI.
“no power enable module x”
“power enable module x”
During the bootup process, Press ESC when the “Waiting for 3 seconds to enter setup mode…” message appears on the terminal (see the example below). If you miss the time window, wait for the ACE module to properly complete booting, reboot the ACE module from the Catalyst 6500 series CLI, and try again to access the setup mode by pressing ESC. The setup mode prompts if you want to reset the admin password. Enter y. The “Resetting admin password to factory default” message appears. The ACE module deletes the admin user password configuration from the startup configuration and resets the password back to the factory default value of admin.
