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 “Safety” on page vii. Do not change
settings or move jumpers on any system-board jumper blocks that are not
labelled in this document.
The clear CMOS jumper 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 forget the administrator password, you cannot reset the
password. 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 .
