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 can
type either 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.
• Remove the battery from the server, wait 30 seconds, and then reinstall it.
• Change the position of the power-on password switch (switch 4) on the system board switch block (SW3)
to bypass the power-on password check (see Table 4 “System board SW3 switch block definition” on
page 31 for more information).
