v Remote Control Security Settings
Select this choice to set a remote-control password. When you set a
remote-control password, you can also set the number of failed attempts to enter
the correct remote-control password, and the duration before another attempt is
allowed.
For a list of supported options for your server, go to
http://www.ibm.com/pc/us/compat/ on the World Wide Web. To order an optional
Remote Supervisor Adapter, contact your IBM marketing representative or
authorized reseller.
Using passwords
The System Security choice appears only on the full Configuration/Setup Utility
menu. After you select this choice, you can implement two levels of password
protection: power-on password and administrator password. The administrator
password is available only if the optional IBM Remote Supervisor Adapter is
installed in your server.
Power-on password
After you set a power-on password, you can enable the Unattended Start mode.
This locks the keyboard and mouse but enables the operating system to start. The
keyboard and mouse remain locked until you type the correct password.
You can use any combination of up to seven characters (A–Z, a–z, and 0–9) for
your power-on password. Keep a record of your password in a secure place. When
a power-on password is set, POST is not completed until you type the password. If
you forget the power-on password, you can regain access to the server through one
of the following methods:
v If an administrator password is set, type the administrator password at the
power-on prompt. (If necessary, see “Administrator password” on page 21 for
details.) Start the Configuration/Setup Utility program and change the power-on
password.
v Remove the battery and then reinstall the battery (see the Option Installation
Guide on the IBM xSeries Documentation CD for instructions).
v Change the position of the power-on password override switch (switch 6 on
switch block 1) as described below to bypass the power-on password check. You
can then start the Configuration/Setup Utility program and change the power-on
password.
Notes:
1. Before changing any switch settings or moving any jumpers, turn off the
server; then, disconnect all power cords and external cables. (Review the
information in “Safety” on page v and “Turning off the server” on page 13.)
2. Any system-board switch or jumper blocks that are not shown in the
illustrations in this book are reserved.
Power-on
password override (switch 6)
Changing the position of this switch bypasses the power-on password
check the next time the server is powered on. You do not need to move
the switch back after the password is overridden. The default position is
Off. To bypass the power-on password check, move the switch to the
opposite position. Changing the position of this switch does not affect the
administrator password check if an administrator password is set.
