Passwords
From the User Security menu choice, you can set, change, and delete a power-on password and an
administrator password.
The User Security menu choice is on the full Setup utility menu only.
If you set only a power-on password, you must type the power-on password to complete the system startup
and to have access to the full Setup utility menu.
An administrator password is intended to be used by a system administrator; it limits access to the full Setup
utility menu. If you set only an administrator password, you do not have to type a password to complete the
system startup, but you must type the administrator password to access the Setup utility menu.
If you set a power-on password for a user and an administrator password for a system administrator, you
must type the power-on password to complete the system startup. A system administrator who types the
administrator password has access to the full Setup utility menu; the system administrator can give the user
authority to set, change, and delete the power-on password. A user who types the power-on password has
access to only the limited Setup utility menu; the user can set, change, and delete the power-on password, if
the system administrator has given the user that authority.
Power-on password
If a power-on password is set, when you turn on the server, you must type the power-on password to
complete the system startup. You can use any combination of 6 - 20 printable ASCII characters for the
password.
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:
• If an administrator password is set, type the administrator password at the password prompt. Start the
Setup utility and reset the power-on 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.
• Remove the battery from the server, wait 30 seconds, and then reinstall it.
