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 Configuration/Setup Utility program and reset the
power-on password.
v
Remove the server battery and then reinstall it. See the Option Installation Guide
for instructions for removing the battery.
v
Change the position of the power-on password override jumper (J22 on the
system board) to bypass the power-on password check (see the following
illustration).
BIOS boot backup (J21)
Password reset (J22)
Force update BMC (J48)
Attention: Before changing any switch settings or moving any jumpers, turn off
the server; then, disconnect all power cords and external cables. See the safety
information beginning on page v. Do not change settings or move jumpers on
any system-board switch or jumper blocks that are not shown in this document.
While the server is turned off, move the jumper on J22 to pin positions 2 and 3
(see previous illustration for jumper location). You can then start the
Configuration/Setup Utility program and reset the power-on password. You do not
have to return the jumper to the previous position.
The power-on password override 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 Configuration/Setup Utility menu. You can use any combination of
up to seven characters (A–Z, a–z, and 0–9) for the password.
Note: The Administrator Password choice is on the Configuration/Setup Utility
menu only if you installed the IBM Remote Supervisor Adapter II Slimline
option.
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 menu
The Boot Menu 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 Configuration/Setup utility program.
Complete the following steps to use the Boot Menu program:
