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.
• Change the position of the power-on password switch (enable switch 2 of the system board switch
block (SW1) to bypass the password check (see "System-board switches and jumpers" on page 27
for more information).
Attention: Before you change any switch settings or move any jumpers, turn off the server; then,
disconnect all power cords and external cables. See the safety information that begins "Safety" on page
v. Do not change settings or move jumpers on any system-board switch or jumper blocks that are
not shown in this document.
The default for all of the switches on switch block SW1 is Off.
While the server is turned off, move switch 2 of the switch block SW1 to the On position to enable the
power-on password override. You can then start the Setup utility and reset the power-on password. You
do not have 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 Setup
utility menu. You can use any combination of 6 to 20 printable ASCII characters for the 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.
