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
Configuration/Setup Utility menu.
If you set a power-on password for a user and an administrator password for a
system administrator, you can type either password to complete the system startup.
A system administrator who types the administrator password has access to the full
Configuration/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 Configuration/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, you must type the
power-on password to complete the system startup. You can use any combination
of up to seven characters (A - Z, a - z, and 0 - 9) for the password.
If 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.
Administrator password
If an administrator password is set, you must type the administrator 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. The
Administrator Password choice is on the Configuration/Setup Utility menu only if
an optional IBM Remote Supervisor Adapter II is installed.
Resetting passwords
If you forget the power-on password or administrator 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 Configuration/Setup Utility program and reset the
power-on password.
v
Remove the battery from the server and then reinstall it. See the Problem
Determination and Service Guide on the IBM System x Documentation CD for
instructions for removing the battery.
v Change the pin position of the clear CMOS (password override) jumper on the
system board to bypass the power-on password and administrator password
check (see “Erasing a lost or forgotten password (clearing CMOS)”).
Erasing a lost or forgotten password (clearing CMOS)
If you forget the power-on or administrator password, you can change the pin
position of the clear CMOS jumper on the system board to bypass the power-on or
administrator password check. This enables you to reset these passwords.
To erase a forgotten password, complete the following steps:
1. Review the safety information that begins on page v and “Handling
static-sensitive devices” on page 18.
2. Turn off the server and all attached devices.
3. Disconnect the power cord.
4. Remove the side cover (see “Removing the side cover” on page 19).
