System and Setup Password Features
The system is shipped without the system password feature enabled. If system security is a concern, operate the system only with system password
protection.
To change or delete an existing password, you must know the password. See "
Deleting or Changing an Existing System Password
." If you forget the
password, you cannot operate the system or change settings in the System Setup program until a trained service technician changes the password jumper
setting to disable the passwords, and erases the existing passwords. See "
Disabling a Forgotten Password
Using the System Password
After a system password is assigned, only those who know the password have full use of the system. When the System Password option is set to Enabled,
the system prompts you for the system password after the system starts.
Assigning a System Password
Before you assign a system password, enter the System Setup program and check the System Password option.
When a system password is assigned, the setting shown for the System Password option is Enabled. If the setting shown for the Password Status is
Unlocked, you can change the system password. If the Password Status option is Locked, you cannot change the system password. When the system
password feature is disabled by a jumper setting, the system password is Disabled, and you cannot change or enter a new system password.
When a system password is not assigned and the password jumper on the system board is in the enabled (default) position, the setting shown for the
System Password option is Not Enabled and the Password Status field is Unlocked. To assign a system password:
1.
Verify that the Password Status option is set to Unlocked.
2.
Highlight the System Password option and press
3.
Type your new system password.
You can use up to 32 characters in your password.
As you press each character key (or the spacebar for a blank space), a placeholder appears in the field.
The password assignment is not case-sensitive. However, certain key combinations are not valid. If you enter one of these combinations, the system
beeps. To erase a character when entering your password, press
Password
Status
Setting the Setup Password option to Enabled prevents the system password from being changed or disabled at system start-up.

Locked. In this state, you cannot change the system password using the System Password option and cannot be disabled at system start
up by pressing
To unlock the system password, enter the setup password in the Setup Password field and then change the Password Status option to
Unlocked. In this state, you can disable the system password at system start up by pressing
using the System Password option.

assigned or if you leave your system unlocked so that someone can disable the password by changing a jumper setting.
