password, you do not have to type a password to complete the system startup, but
you must type the supervisor password to access the Configuration/Setup Utility
menu.
If you set a user password for a user and a supervisor password for a system
administrator, you can type either password to complete the system startup. A
system administrator who types the supervisor password has access to the full
Configuration/Setup Utility menu; the system administrator can give the user
authority to set, change, and delete the user password. A user who types the user
password has access to only the limited Configuration/Setup Utility menu; the user
can set, change, and delete the user password, if the system administrator has
given the user that authority.
User password
If a user (power-on) password is set, when you turn on the server, the system
startup will not be completed until you type the user password. You can use any
combination of up to seven characters (A–Z, a–z, and 0–9) for the password.
When a user 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 user password.
When a user password is set, POST is not completed until you type the password.
If you forget the user password, you can regain access to the server in any of the
following ways:
v If a supervisor password is set, type the supervisor password at the password
prompt (see "Supervisor password"). Start the Configuration/Setup Utility program
and reset the user password.
v Remove the server battery and then reinstall it. See the Option Installation Guide
on the IBM xSeries Documentation CD for instructions for removing the battery.
v Change the position of the clear CMOS (password override) jumper on the
system board to bypass the user password check. See "Resetting passwords" for
additional information.
Supervisor password
If a supervisor (administrator) password is set, you must type the supervisor
password for access to the full Configuration/Setup Utility menu. You can use any
combination of up to seven characters (A–Z, a–z, and 0–9) for the password.
If you forget the supervisor password, you can reset it after you change the position
of the clear CMOS jumper. See "Resetting passwords" for additional information.
