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:
Types 2254, 2256, 2257, 6336, 6337, 6339, 6341, 6342, 6346, 6347, 6438 have Enhanced
Security Mode. If Enhanced Security mode is enabled and there is no password given, the
computer will act as if Enhanced Security is 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. Refer to “Setup
Utility program” on page 10.
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 200.
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, riser card, memory, and processor).
At the time of computer manufacture, the EPROM will be loaded with the serial
numbers of the system and all major components. The customer will have access to
the MIF file via the DMI MIF Browser that is installed with the preload and is also
available on the SSCD that is provided with the system.
