All microprocessors of speed 450MHz and up will
automatically set their internal speeds, so the switch
setting is not applicable.
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:
Ÿ
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 26.
Ÿ
Change switch 8 on the system switch block to On
(Bypass Power-On Password). See “System board
connectors” on page 143 for the location of the
switch block.
