3. Follow the instructions that appear on the screen.
Using passwords
The System Security choice appears only on the full Configuration/Setup Utility
menu. After you select this choice, you can implement two levels of password
protection: power-on password and administrator password.
Power-on password
After you set a power-on password, you can enable the Unattended-Start mode.
This locks the keyboard and mouse but enables the system to start the operating
system. The keyboard and mouse remain locked until you type the correct
password.
You can use any combination of up to seven characters (A–Z, a–z, and 0–9) for
your power-on password. Keep a record of your password in a secure place. When
a power-on password is set, POST is not completed until you type the password. If
you forget the power-on password, you can regain access to the server through one
of the following methods:
v
If an administrator password is set, type the administrator password at the
power-on prompt. (If necessary, see “Administrator password” for details.) Start
the Configuration/Setup Utility program and change the power-on password.
v Remove the battery and then reinstall the battery (see “Replacing the battery” on
page 69 for instructions).
v Change the position of the power-on password override switch (switch 6 on
switch block 1) to bypass the power-on password check. You can then start the
Configuration/Setup Utility program and change the power-on password.
Notes:
1. Before changing any switch settings or moving any jumpers, turn off the
server; then, disconnect all power cords and external cables.
2. Any system-board switch or jumper blocks that are not shown in the
illustrations in this book are reserved.
3. Changing the position of the power-on password override switch bypasses
the power-on password check the next time the server is turned on. You do
not need to move the switch back after the password is overridden. The
default position is Off. To bypass the power-on password check, move the
switch to the opposite position.
4. Changing the position of this switch does not affect the administrator
password.
Administrator password
Select this choice to set an administrator password. The administrator password
provides access to all choices on the Configuration/Setup Utility main menu.
Note: This choice is available on the Configuration/Setup Utility menu only if the
optional IBM Remote Supervisor Adapter is installed in your server.
When you use an administrator password, you can set, change, or delete both the
administrator and power-on passwords and allow a power-on password to be
changed by the user. You can use any combination of up to seven characters (A–Z,
a–z, and 0–9) for your administrator password. Keep a record of your password in a
secure place.
Attention: If an administrator password is set and then forgotten, it cannot be
overridden or removed. You must replace the system board.
