System and Setup Password Features

NOTICE: The password features provide a basic level of security for the data on your system. If your data requires

more security, use additional forms of protection, such as data encryption programs.

NOTICE: Anyone can access the data stored on your system if you leave the system running and unattended

without having a system password assigned or if you leave your system unlocked so that someone can disable the password by changing a jumper setting.

Your system is shipped to you without the system password feature enabled. If system security is a concern, operate your system only with system password protection.

Using the System Setup Program 35

To change or delete an existing password, you must know the password. See "Deleting or Changing an Existing System Password" on page 37. If you forget your password, you cannot operate your 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" on page 39.

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:

Verify that the

NOTE: Password protection does not take effect until you reboot the system.

Using Your System Password to Secure Your System

NOTE: If you have assigned a setup password (see "Using the Setup Password" on page 38), the system accepts

your setup password as an alternate system password.

When the Password Status option is set to Unlocked, you have the option to leave the password security enabled or to disable the password security.

To leave the password security enabled:

Turn on or reboot your system by pressing <Ctrl><Alt><Del>.

Type your password and press <Enter>.

To disable the password security:

Turn on or reboot your system by pressing <Ctrl><Alt><Del>.

Type your password and press <Ctrl><Enter>.

When the Password Status option is set to Locked, whenever you turn on your system or reboot your system by pressing <Ctrl><Alt><Del>, type your password and press <Enter> at the prompt.

After you type the correct system password and press <Enter>, your system operates as usual.

If an incorrect system password is entered, the system displays a message and prompts you to re-enter your password. You have three attempts to enter the correct password. After the third unsuccessful attempt, the system displays an error message showing the number of unsuccessful attempts and that the system has halted and will shut down. This message can alert you to an unauthorized person attempting to use your system.

Even after you shut down and restart the system, the error message continues to be displayed until the correct password is entered.

NOTE: You can use the Password Status option in conjunction with the System Password and Setup Password

options to further protect your system from unauthorized changes.

Using the Setup Password

Assigning a Setup Password

You can assign (or change) a setup password only when the Setup Password option is set to Not Enabled. To assign a setup password, highlight the Setup Password option and press the <+> or <–> key. The system prompts you to enter and verify the password. If a character is illegal for password use, an error message appears.

NOTE: The setup password can be the same as the system password. If the two passwords are different, the setup

password can be used as an alternate system password. However, the system password cannot be used in place of the setup 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.

After you verify the password, the Setup Password setting changes to Enabled. The next time you enter the System Setup program, the system prompts you for the setup password.

A change to the Setup Password option becomes effective immediately (restarting the system is not required).

Operating With a Setup Password Enabled

If Setup Password is set to Enabled, you must enter the correct setup password before you can modify most of the System Setup options. When you start the System Setup program, the program prompts you to enter a password.

If you do not enter the correct password in three attempts, the system lets you view, but not modify, the System Setup screens—with the following exception: If System Password is not set to Enabled and is not locked through the Password Status option, you can assign a system password (however, you cannot disable or change an existing system password).

NOTE: You can use the Password Status option in conjunction with the Setup Password option to protect the

system password from unauthorized changes.

) and configure the tape drive according to the documentation that

came with the tape drive, based on the following guidelines:

Each device attached to a SCSI host adapter must have a unique SCSI ID number. (Narrow SCSI devices use IDs 0 to 7; wide SCSI devices use IDs from 0 to 15.) Set the drive’s SCSI ID to avoid conflicts with other devices on the SCSI bus. For the default SCSI ID setting, see the documentation provided with the drive.

NOTE: There is no requirement that SCSI ID numbers be assigned sequentially or that devices be attached to

the cable in order by ID number.

SCSI logic requires that the two devices at opposite ends of a SCSI chain be terminated and that

all devices in between be unterminated. Therefore, you enable the tape drive’s termination if it is the last device in a chain of devices (or sole device) connected to the SCSI controller.

Attach the three shoulder screws to the drive. See Figure 3-19.
