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 on page vii. 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 (SW4) is Off.
While the server is turned off, move switch 1 of the switch block (SW4) 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 up to seven characters (A - Z,a-z,and0-9)forthepassword.
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.
