Disabling a forgotten password
The software security features of sled 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.
Prerequisites
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

your warranty. Read and follow the safety instructions that came with the product.
Steps
1. Turn off the sled using the operating system commands or the CMC.

3. Move the jumper on the system-board jumper from pins 1 and 2 to pins 2 and 3.
4. Install the sled in the enclosure.
5. Turn on the sled.
When the sled is on, the power-on indicator is solid green. Allow the sled to finish booting.
The existing passwords are not disabled (erased) until the system boots with the password jumper on pins 2 and 3. However,
before you assign a new system and/or setup password, you must reinstall the password 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.
