Restart the server and press 'F8' when prompted during the POST. The iLO starts running, and you will be prompted to enter a username and password. Enter the valid iLO user ID and password. The defaults are 'administrator' for the username, and the number from the tag attached to the server for the password.
Enter the serial number of the server in the DNS field. Click 'OK' when you are finished and you will be signed in to iLO.
Change the default administrator password if you want by clicking 'Administrator' at the bottom of the page. Enter the new password in the password field and hit 'F10' on your keyboard to apply it.
Click 'File' and then 'Quit' to close iLO. The server will automatically reboot. When iLO comes back up, type the new password in the password field and click 'OK.' Your new password will be changed.
