Attention: Before you change any switch settings or move any jumpers, turn off the server; then,
disconnect all power cords and external cables. Read “Safety” on page v, this information will help you
work safely. 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 SW7 is Off.
While the server is turned off, move switch 6 on switch block SW7 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
This section explains the 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.
