Attention: Before you change any switch settings or move any jumpers, turn
off the server; then, disconnect all power cords and external cables. See the
safety information that begins on page vii. Do not change settings or move
jumpers on any system-board switch or jumper blocks that are not shown in this
document.
The default for all of the switches on switch block (SW4) is Off.
While the server is turned off, move switch 1 of the switch block (SW4) 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 - 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 program
The Boot Manager program 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 program, 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. If a
bootable USB mass storage device is installed, a submenu item ( USB
Key/Disk ) is displayed.
4. Use the Up arrow and Down arrow keys to select an item from the Boot
Selection 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
J29 jumper in the backup position (pins 2 and 3).
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 J29 jumper back to
the primary position (pins 1 and 2).
