CAUTION:
Be careful when changing the BIOS settings. The BIOS interface is designed for advanced users. Any
change in the setting could prevent your system from starting correctly and you might have potential loss of
data.
Disabling a forgotten password
The software security features of the system include a system password and a setup password. The password jumper enables or
disables password features and clears any password(s) currently in use.
Prerequisites
CAUTION:
Many repairs may only be done by a certified service technician. You should only perform

Steps
1. Power off the compute sled and remove the compute sled from chassis.
2. Move the jumper on the system board from pins 1 and 2 to pins 2 and 3.
NOTE:
The existing passwords are not disabled (erased) until the system boots with the jumper on pins 2 and 3.
However, before you assign a new system and/or setup password, you must move the jumper back to pins 1 and 2.
NOTE:
If you assign a new system and/or setup password with the jumper on pins 2 and 3, the system disables the new
password(s) the next time it boots.
