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, and 0–9) 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 jumper”.
• Remove the battery and then install the battery.
Setting the password override jumper: When a power-on password is set, POST
does not complete until you enter the password. If you forget the power-on password,
you can regain access to the server through either of the following methods:
• Enter the administrator password at the power-on prompt, if an administrator
password has been set. (If necessary, see “Administrator password” for details.)
Start the Configuration/Setup Utility program, and change the power-on
password.
• Change the position of the jumper on J15 as described in Table 2 on page 19 to
bypass the power-on password check. You can then start the
Configuration/Setup Utility program and change the power-on password.
Table 2 on page 19 contains the names and descriptions of jumper J15, located on
the system board.
Notes:
1. Turn off the server, and disconnect all power cords before moving any
jumpers.
2. Jumpers J17 and J3 are located on the same jumper block as jumper J15 on
the system board. These jumpers are set to
Disabled
. Do not change the
settings on these jumpers.
Attention: If you change the settings on these jumpers, the server will fail.
