Figure 92. System-board switches, jumpers, and buttons
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.
While the server is turned off, move power-on password switch (switch 4) on the system board switch
block (SW3) 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.
Using the Boot Manager
The Boot Manager program is a built-in, menu-driven configuration utility program that you can use to
temporarily redefine the first startup device without changing settings in the Setup utility.
