Applicable to: World-Wide

System Security
To control access to the server security features, such as adding passwords, securing diskette access, and defining
a system owner's name that displays during startup can be implemented:

To set, change, or delete a password:
1. Select System Security.
2. Select the password that you want to change.

The System Security choice appears only on the full Configuration/Setup menu.

After a power-on or administrator password is set, you must enter the password when you power-on the server.

(The passwords do not appear on the screen as you type them.)

Type of Password	Results
No password set	No password required to start system. User can access all choices on the Configuration/Setup utility program menu.
Power-on password only	User must enter password to complete the system startup. Power-on password provides access to all choices on the Configuration/Setup utility program menu.
Administrator password	User must enter password to complete the system startup. Administrator password provides access to all choices on the Configuration/Setup utility program menu.
Administrator and power-on password	User can enter either password to complete the system startup. Administrator password provides access to all choices on the Configuration/Setup utility program menu. 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. Power-on password provides access to a limited set of choices on the Configuration/Setup utility program menu. This might include changing or deleting the power-on password.

Administrator Password Menu: The administrator password (sometimes called a supervisor-level password) controls access to some features of the server, including the Configuration/Setup utility program.

Attention If an administrator password is set and then forgotten, it cannot be overridden or removed. You must replace the system board.

To set an administrator password:
1. Select Administrator Password on the System Security menu; then press Enter.

The Administrator Password menu appears.

2. Type the password in the Enter Administrator Password data field.

A password can contain any combination of up to seven alphanumeric characters (A Z, a z, and 0 9). Keep a record of the password in a secure place.

3. Move the cursor to the Enter Administrator Password Again data field and type the password again.

4. Select Set or Change Administrator Password to save the new password; then press Enter. The password becomes effective immediately.

Note A message appears if the two passwords do not match. If this happens, press Enter to cancel the request and return to the System Security menu.

To delete an administrator password:
1. Select Administrator Password on the System Security menu; then press Enter.

Following a warning, the Administrator Password menu appears.

2. Select Delete Administrator Password; then press Enter.

3. A confirmation window appears. Press Enter to delete the administrator password. Press Esc to return to the System Security menu.

To enable a user to change the power-on password:
1. Select Administrator Password on the System Security menu; then press Enter. The Administrator Password screen appears.

2. Select Power-on password changeable by user. Press the Left Arrow or Right Arrow key to toggle the entry to Yes.

When this choice is enabled, System Security appears on the limited Configuration/Setup menu. The System Security menu contains the Power-on Password choice.

Using the Power-on Password Menu: When a power-on password is set, you must enter a password each time you start the system.

To set a power-on password:
1. Select Power-on Password on the System Security menu; then press Enter. The Power-on Password menu appears.

2. Type the password in the Enter Power-on Password data field. You can use any combination of up to seven characters (A Z, a z, and 0 9) for the power-on password. Keep a record of the password in a secure place.

3. Move the cursor to the Enter Power-on Password Again data field and type the password again.

4. Select Set or Change Power-on Password to save the new password; then press Enter.

Note A message appears if the two passwords do not match. If this happens, press Esc to cancel the request and return to the System Security menu.

If you forget the power-on password, and an administrator password has been set, use the administrator password at the power-on prompt; then start the Configuration/Setup utility program and change the power-on password. If no administrator password has been set, you must move the Clear CMOS jumper to remove the power-on password, see "Removing an Unknown Power-on Password".

To delete a power-on password:
1. Select Power-on Password on the System Security menu; then press Enter. The Power-on Password menu appears.

2. Select Delete Power-on Password; then press Enter.

3. A confirmation window appears. Press Enter to delete the power-on password. Press Esc to cancel the request and return to the System Security menu.

To turn off the prompt for the power-on password:
1. Select Power-on Password on the System Security menu; then press Enter. The Power-On Password screen appears.

2. Select Password Prompt. Press the Left Arrow or Right Arrow key to toggle the entry to Off.

System Owner's Name: You can specify a system owner's name that displays during POST, each time the server is started. The system owner's name can only be removed or changed from the System Security menu; it is not affected by moving the Clear CMOS jumper. If you set an administrator password, only the administrator can set, change, or delete the system owner's name.

1. Select System Owners Name on the System Security screen, and press Enter. The System Owners Name screen appears.

2. Type the name in the Enter System Owners Name String data field. You can use any combination of up to 15 characters and spaces for the system owner's name.

3. Press the Down Arrow key to select the Set or Change System Owners Name data field.

4. Press Enter to set the name or change a previously defined name.

To delete the system owner's name, select Delete Stored System Owners Name and press Enter.

Restricting Access to Diskette Drives: The setting for the Secure Diskette Drives option controls who has access to the diskettes (user and administrator, or administrator only). The server comes with this feature set to Enable, so that both the user and administrator have access to diskette drives.

To change this setting so that the access to the diskette drives is disabled, select the System Security menu option and then select Secure Diskette Drives. Press the Left Arrow or Right Arrow key to toggle the entry to Disable in the Diskette Drive Access data field. If the administrator password is enabled, only the administrator can change this setting.

Start Options: Start options take effect when you start the server.

You can select keyboard operating characteristics, such as the keyboard speed. You can also specify whether the keyboard number lock starts on or off. You can also enable the server to run in disketteless and monitorless operation.

The server uses a startup sequence to determine the device from which the operating system loads. For example, you can define a startup sequence that checks for a startable diskette in the primary diskette drive, then checks the hard disk drive in bay 7, and then checks a network adapter.

You can enable a virus-detection test that checks for changes in the master boot record at start up. You can also choose to run POST in an enhanced mode or a quick mode.

Select Start Options, then use the Left Arrow and Right Arrow keys to advance through each data field.

The Start Options choice appears only on the full Configuration/Setup menu.

Advanced Setup: Select Advanced Setup to change values for advanced hardware features such as cache control and ROM shadowing.

A warning message displays above the choices on this menu, to alert you that the system may malfunction if these options are configured incorrectly. Follow the instructions on the screen carefully.

Use the Left Arrow and Right Arrow keys to advance through the options for the selected menu item.

The Advanced Setup choice appears only on the full Configuration/Setup menu.

Cache Control: Select this choice to define the microprocessor cache state as enabled or disabled. In addition, you can define the microprocessor cache type as write-back or write-through.

You can also enable or disable video BIOS caching, and define buffers for video and option ROM caching.

PCI Control: Select this choice to view the assigned interrupt requests (IRQs) for PCI adapters installed in the server, and for the SCSI and Ethernet controllers on the system board.

ROM Shadowing: Select this choice to enable ROM shadowing in specified areas. When these areas are enabled, the contents can be cached, using the Cache Control option.

Universal Serial Bus: Use this choice to enable the Universal Serial Bus and to set the clock speed for the USB devices. The documentation for the devices should specify the proper clock speed. If you are installing two USB devices, they should have the same clock speed.

Memory Settings: Use this choice to select the memory speed and the type of error detection.

The server supports 60 ns DIMMs. You can specify the type of error detection that the server uses as ECC or parity, or you can specify that no error correction is performed.
