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 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 switch (switch 6 on
switch block 1 on the system board) to bypass the power-on password check.
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
.
While the server is turned off, move the switch to the position opposite its current
position. You can then start the Configuration/Setup Utility program and reset the
power-on password. You do not need 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 Configuration/Setup Utility menu. You can use any combination of
up to seven characters (A–Z, a–z, and 0–9) for the password. The Administrator
Password choice is on the Configuration/Setup Utility menu only if an optional IBM
Remote Supervisor Adapter II SlimLine is installed.
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.
Remote-control password
If a remote-control password is set, you must type the remote-control password to
access the server remotely. You can use any combination of up to seven characters
(A–Z, a–z, and 0–9) for the password. You can specify the number of failed
attempts to enter the correct remote-control password that are allowed and the
duration that must elapse before another attempt is allowed. The Remote-Control
Password choice is on the Configuration/Setup Utility menu only if an optional IBM
Remote Supervisor Adapter II SlimLine is installed.
Using the ServerGuide Setup and Installation CD
The ServerGuide Setup and Installation CD includes an easy-to-use setup and
installation program that is designed for your IBM server. The ServerGuide program
detects the server model and hardware options that are installed and uses that
information during setup to configure the hardware. The ServerGuide program
simplifies operating-system installations by providing updated device drivers and, in
some cases, installing them automatically.
Note: The ServerGuide program works only with 32-bit Windows operating
systems.
