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 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 SW3 is Off.
While the server is turned off, move switch 4 of the 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.
