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