Cisco 11503 - CSS Content Services Switch Administration Manual page 370

The administrative username and password are stored in nonvolatile random
access memory (NVRAM). Each time you reboot the CSS, it reads the username
and password from NVRAM and reinserts them into the user database. SuperUser
status is assigned to the administrative username by default.
You can change the administrative username and password, but because the
information is stored in NVRAM, you cannot permanently delete them. If you
delete the administrative username using the no username command, the CSS
deletes the username from the running-config file, but restores the username from
NVRAM when you reboot the CSS.
To change the administrative username and password through the Offline DM
Main menu:
