Passwords
From the User Security menu choice, you can set, change, and delete a power-on
password and an administrator password. The User Security choice is on the full
Setup utility menu only.
If you set only a power-on password, you must type the power-on password to
complete the system startup and to have access to the full Setup utility menu.
An administrator password is intended to be used by a system administrator; it
limits access to the full Setup utility menu. If you set only an administrator
password, you do not have to type a password to complete the system startup, but
you must type the administrator password to access the Setup utility menu.
If you set a power-on password for a user and an administrator password for a
system administrator, you must type the power-on password to complete the system
startup. A system administrator who types the administrator password has access to
the full Setup utility menu; the system administrator can give the user authority to
set, change, and delete the power-on password. A user who types the power-on
password has access to only the limited Setup utility menu; the user can set,
change, and delete the power-on password, if the system administrator has given
the user that authority.
Power-on password: If a power-on password is set, when you turn on the server,
the system startup will not be completed until you type the power-on password. You
can use any combination of between six and 20 printable ASCII characters for the
password.
When a power-on password is set, you can enable the Unattended Start mode, in
which the keyboard and mouse remain locked but the operating system can start.
You can unlock the keyboard and mouse by typing the power-on password.
If you forget the power-on password, you can regain access to the server in any of
the following ways:
v If an administrator password is set, type the administrator password at the
password prompt. Start the Setup utility and reset the power-on password.
v Remove the battery from the server and then reinstall it. (See “Removing the
battery” on page 229 and “Installing the battery” on page 231 for more
information.)
v Change the position of the power-on password switch (enable switch 1 of the
system board switch block (SW4) to bypass the power-on password check (see
“System-board switches and jumpers” on page 17 for more information).
