Using Passwords; Power-On Password - IBM eserver xSeries 350 User Reference Manual

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.

Power-on password

After you set a power-on password, you can enable the unattended-start mode. This
locks the keyboard and mouse, but allows the system to start the operating system.
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. If you forget
the power-on password, you can regain access to the server through one of the
following methods:
•
•
•
Setting the password override jumper: When a power-on password is set, POST
does not complete until you type the password. If you forget the power-on password,
you can regain access to the server through either of the following methods:

IBM® xSeries 350: User's Reference
If an administrator password is set, type the administrator password at the
power-on prompt. Start the Configuration/Setup Utility program and change the
power-on password.
Change the position of the password override jumper as described in "Setting the
password override jumper".
Remove the battery and then install the battery.
Type the administrator password at the power-on prompt, if an administrator
password has been set. (If necessary, see "Administrator password" on page 19
for details.) Start the Configuration/Setup Utility program, and change the
power-on password.
Change the position of the jumper on J15 to bypass the power-on password check.
You can then start the Configuration/Setup Utility program and change the
power-on password.
Changing the position of the power-on password override jumper on J15
bypasses the power-on password check if the jumper has been moved since the
server was last powered on. You do not need to move the jumper back to the
default position after the password is overridden. The default position is a
jumper on pins 1 and 2.
Changing the position of this jumper does not affect the administrator password
check if an administrator password is set.
Note: Turn off the server, and disconnect all power cords before moving any
jumpers.
Attention: Jumpers J17 and J3 are located on the same jumper block as jumper
J15 on the system board. These jumpers are set to Disabled. Do not change the
settings on these jumpers. If you change the settings on these jumpers, the server
will fail.
