Disabling A Forgotten Password

The blade's software security features include a system password and a setup password. The password jumper enables
these password features or disables them, and clears any password(s) currently in use.
CAUTION: Many repairs may only be done by a certified service technician. You should only perform
troubleshooting and simple repairs as authorized in your product documentation, or as directed by the online or
telephone service and support team. Damage due to servicing that is not authorized by Dell is not covered by your
warranty. Read and follow the safety instructions that came with the product.
1. Remove the blade from the sleeve.
2. Remove the blade system board to gain access to the jumpers.
3. Relocate the jumper plug to disable the password feature.
4. Reinstall the blade system board.
5. Install the blade in the sleeve.
When the blade is on, the power-on indicator is solid green. Allow the blade to finish booting.
The existing passwords are not disabled (erased) until the system boots with the password removed. However,
before you assign a new system and/or setup password, you must reinstall the password jumper.
NOTE: If you assign a new system and/or setup password with the jumper removed, the system disables the new
password(s) the next time it boots.
