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 “Removing the
system battery” on page 209 for instructions for removing the battery.
v Clear CMOS data by using the clear CMOS jumper (see “System-board jumpers”
on page 28 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.
Clearing CMOS data does not affect the administrator password.

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.
