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 “Safety” 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 (SW2) is Off.
While the server is turned off, move switch 3 of the switch block (SW2) 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.
