or exit without saving the changes.
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 allows the system to start the operating system.
The keyboard and mouse remain locked until you enter the correct password.
You can use any combination of up to seven characters (A–Z, a–z, 0–9 and blanks) for
your power-on password. Keep a record of your password in a secure place. If you
forget the power-on password, you can regain access to the server through one of the
following methods:
• If an administrator password is set, enter the administrator password at the
power-on prompt. Start the Configuration/Setup Utility program and change the
power-on password.
• Change the position of the password override jumper as described in “Setting the
password override switch”.
• Remove the battery and then install the battery.
Setting the password override switch: The following illustration shows the location
of the password override switch, switch 8 of switch block 1, on the system board.
Note: The illustrations in this document might differ slightly from your hardware.
To set the password override switch:
1. Review the information in “Before you begin” on page 42.
