4. Power-on the computer. The system senses the change in the switch setting and
erases the password.
5. Set switch 3 back to the off position.
6. 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.
Administrator password control
The Administrator password is set in the Setup Configuration. Refer to “Setup Utility
program” on page 5.
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 93.
Alert on LAN2
Alert on LAN2 provides notification of changes in the computer, even when the
computer power is turned off. Working with DMI and Wake on LAN
®
technologies,
Alert on LAN2 helps to manage and monitor the hardware and software features of
the computer. Alert on LAN2 generates notifications to the server of these
occurrences:
• Computer disconnected from the network
• Computer unplugged from the power outlet
• All POST errors
• Operating system or POST hang condition
Alert on LAN2 events are configured to be Enabled or Disabled from the LAN server
only, and not from the computer. See the LAN administrator for configuration status
information.
Note:
Type 6866 has 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.
