Disabling a forgotten password
The sled 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. Turn off the nodes using the operating system commands, or the iDRAC, or the CMC.
The sled is powered off when all the nodes are turned off.
2. Remove the sled from the enclosure.
3. Locate the jumpers on the system board.
4. Relocate the jumper plug to disable the password feature.
5. Install the sled in the enclosure.
6. Turn on the sled.
When the sled is on, the power-on indicator is solid green. The nodes also power on when the sled is turned on, and the node
indicators are solid blue. Allow the sled 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.
7. Turn off the nodes using the operating system commands, or the iDRAC, or the CMC.
