Bypassing an Unknown Power-on Password
When a power-on password is set, POST does not complete until you enter the
password. If you forget the power-on password, you can regain access to the
server through one of the following methods:
Enter the administrator password at the power-on prompt, if an administrator
password has been set. (If necessary, see “Using the Administrator Password
Menu” on page 27 for details.) Start the Configuration/Setup Utility programs
and change the power-on password. See “Using the Power-on Password
Menu” on page 25.
Change switch 8 on the system switch block to On (Bypass Power-On
Password). See “System Board Connectors” on page 169 for the location of
the switch block.
