Administrator password
If an administrator password is set, you must type the administrator password for access to the full Setup
utility menu. You can use any combination of up to seven characters (A - Z, a - z, and 0 - 9) for the
password.
If you forget the administrator password, you can reset it after you change the position of the clear
CMOS jumper.
Resetting passwords
If you forget the power-on password or administrator password, you can move the clear-CMOS jumper
block on the system board to pins 2 and 3, to clear CMOS memory and bypass the power-on or
administrator password check. The jumper location is shown in the following illustration.

Notes:
1.
If no jumper is present, the server responds as if the pins are set to 1 and 2.
2.
Changing the position of the UEFI boot recovery jumper from pins 1 and 2 to pins 2 and 3 before the server is
turned on alters which flash ROM page is loaded. Do not change the jumper pin position after the server is
turned on. This can cause an unpredictable problem.
