While the server is turned off, move switch 6 on the switch block SW7 to the On
position to enable the power-on password override. You can then start the Setup
utility and reset the power-on password. You do not have to return the switch to
the previous position.
The power-on password override switch does not affect the administrator
password.
Administrator password:
If an administrator password is set, you must type the administrator password for
access to the full Setup utility menu. You can use any combination of 6 to 20
printable ASCII characters for the password.
Attention:
If you set an administrator password and then forget it, there is no
way to change, override, or remove it. You must replace the system board.
Using the Boot Manager
The Boot Manager is a built-in, menu-driven configuration utility program that
you can use to temporarily redefine the first startup device without changing
settings in the Setup utility.
To use the Boot Manager, complete the following steps:
1.
Turn off the server.
2. Restart the server.
3. When the prompt <F12> Select Boot Device is displayed, press F12.
4. Use the Up arrow and Down arrow keys to select an item from the menu and
press Enter.
The next time the server starts, it returns to the startup sequence that is set in the
Setup utility.
Starting the backup server firmware
The system board contains a backup copy area for the server firmware. This is a
secondary copy of the server firmware that you update only during the process of
updating the server firmware. If the primary copy of the server firmware becomes
damaged, use this backup copy.
To force the server to start from the backup copy, turn off the server; then, place
the J71 jumper (UEFI boot recovery jumper) in the backup position (pins 2 and 3).
See “System-board switches, jumpers, and buttons” on page 28 for the location of
the UEFI boot recovery jumper (J71).
Use the backup copy of the server firmware until the primary copy is restored.
After the primary copy is restored, turn off the server; then, move the J71 jumper
back to the primary position (pins 1 and 2).
