Power-on password
If a power-on password is set, when you turn on the server, the system startup will
not be completed until you type the power-on password. You can use any
combination of between six and 20 printable ASCII characters for the password.
When a power-on password is set, you can enable the Unattended Start mode, in
which the keyboard and mouse remain locked but the operating system can start.
You can unlock the keyboard and mouse by typing the power-on password.
If you forget the power-on password, you can regain access to the server in any of
the following ways:
v If an administrator password is set, type the administrator password at the
password prompt. Start the Setup utility and reset the power-on password.
v Remove the battery from the server and then reinstall it. See the Problem
Determination and Service Guide on the IBM Documentation CD for instructions
for removing the battery.
v Change the position of the power-on password switch (enable switch 1 of the
system board switch block (SW4) to bypass the power-on password check (see
“System-board switches and jumpers” on page 30 for more information).
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 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 between six
and 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 Selection Menu program
The Boot Selection Menu is used to temporarily redefine the first startup device
without changing boot options or settings in the Setup utility.
To use the Boot Selection Menu program, complete the following steps:
1. Turn off the server.
2. Restart the server.
3. Press F12 (Select Boot Device). 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.
