Passwords
From the Security choice, you can set, change, and delete a user (power-on)
password and a supervisor password.
If you set only a user password, you must type the user password to complete the
system startup.
A supervisor password is intended to be used by a system administrator; it limits
access to the configuration choices. If you set only a supervisor password, you do
not have to type a password to complete the system startup, but you must type the
supervisor password to access all the BIOS Setup Utility program configuration
choices.
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
BIOS Setup Utility program configuration choices; 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 BIOS Setup Utility program
configuration choices; 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 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.
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 BIOS Setup Utility program and
reset the user password.
v
Remove the battery from the server and then reinstall it. For instructions for
removing the battery, see the
Problem Determination and Service Guide on the
IBM Documentation CD.
v Press the Clear CMOS button on the system board to clear the user and
supervisor passwords. See the
Problem Determination and Service Guide on the
IBM Documentation CD for additional information.
Supervisor password
If a supervisor password is set, you must type the supervisor password for access
to the full BIOS Setup Utility settings. 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 press the Clear
CMOS button. See the
Problem Determination and Service Guide on the IBM
Documentation CD for additional information.
