All Dell DRACs come with a default account set up as root / calvin which is a huge security risk if left!
The web interface doesn’t let you change the password but the firmware does when you boot the server.
A second way to change the password is with the racadm tool, if installed, at the command line! This means you don’t have to reboot that precious production server!
In DRAC 4, the first index slot is root by default. In DRAC 5 and 6, index 1 is Administrator, index 2 is root.
