2. See “System Board Layout” on page H-5 to find the password jumper.
3. Move the password jumper to connect the center pin and the pin on the
opposite end of the connector.
4. Power-on the computer. The system senses the change in the position and
erases the password.
Note: It is necessary to move the jumper back to the previous position.
5. Remind the user to enter a new password when service is complete.
Administrator Password: The administrator password is used to restrict access
to the Configuration/Setup Utility program. If the administrator password is
activated, and you do not enter the administrator password, the configuration can
be viewed but not changed.
| Note: Type 6578 has the Enhanced Security mode feature. If the Enhanced
| Security mode is enabled and there is no password given, the computer
| acts as if Enhanced Security were disabled.
| If Enhanced Security is enabled and an administrator password is given, the
| administrator password must be entered to use the computer. If the
| administrator password is lost or forgotten, the system board in the
| computer must be replaced in order to regain access to the
| Configuration/Setup Utility program.
Administrator Password Control The administrator password is set in the Setup
Configuration. See “Service Processor Configuration / Setup Utility” on page H-8.
Operating System Password: An operating system password is very similar to a
power-on password and denies access to the computer by an unauthorized user
when the password is activated. The computer is unusable until the password is
entered and recognized by the computer.
Vital Product Data
Each computer has a unique vital product data (VPD) code stored in the nonvolatile
memory on the system board. After you replace the system board, the VPD must
be updated. To update the VPD, see “Flash (BIOS/VPD) Update Procedure” on
page 3-33.
Management Information Format (MIF)
Management Information Format (MIF) is a file used to maintain a list of the system
unit serial number along with all serialized components; for example: system
board, memory, and processor.
At the time of computer manufacture, the EPROM is loaded with the serial numbers
of the system and all major components. The customer will have access to the
MIF file through the DMI MIF Browser that is installed with the preload and is also
available on the SSCD provided with the system.
Example Scenario: As an example, a company called Retain-a-Group is a central
data warehouse offering serial number data management. Retain-a-Group acts as
a focal point to law enforcement. The customer has the option to purchase serial
number information and services from Retain-a-Group. It is the customer’s
responsibility to maintain the MIF file and to inform Retain-a-Group of any changes
to the file.
