the power-on password check. See “Resetting passwords” for additional
information.
Important: 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 on page vii. Do not change settings or move jumpers on any
system-board switch or jumper block that is not shown in this document.
Attention: In a dc power environment, only trained service personnel other than
IBM service technicians are authorized to connect or disconnect power to the dc
power supply. See the documentation that comes with each dc power supply.
Administrator password
If an administrator password is set, you must type the administrator password for
access to the full Configuration/Setup Utility menu. You can use any combination of
up to seven characters (A–Z, a–z, and 0–9) for the password.
Resetting passwords
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. If you forget the user
power-on password, you can move the power-on password override switch on the
system board to the On position to bypass the power-on password check. The
power-on password override switch is switch 5 on switch block SW2. The switch
location is shown in the following illustration.
