power cords; then, remove the cover. See “Removing the cover” on page 44.

password for one boot cycle.
Note: This means that you can now start or power-up the server one time
without having to use the power-on password. But if you do not use the
Configuration/Setup Utility program to change or delete the password,
the next time you start the server the original power-on password will be
reinstated.
4. Connect the server to a power source, keyboard, monitor, and mouse.
5. Power-up the server.
Note: You can now start the Configuration/Setup Utility program and either delete
the old or set a new power-on password.
Administrator password
Select this choice to set an administrator password. The administrator password
provides access to all choices on the Configuration/Setup Utility main menu. You can
set, change, or delete both the administrator and power-on passwords, and allow a
power-on password to be changed by the user.
Attention: If an administrator password is set and then forgotten, it cannot be
overridden or removed. You must replace the system board.
The following table provides a summary of the password features.
