Power-on password:
If a power-on password is set, when you turn on the server, you must type the
power-on password to complete the system startup. You can use any combination
of6-20printable ASCII characters for the password.
When a power-on password is set, you can enable the Unattended Start mode, in
which the keyboard and mouse remain locked but the operating system can start.
You can unlock the keyboard and mouse by typing the power-on password.
If you forget the power-on password, you can regain access to the server in any of
the following ways:
v If an administrator password is set, type the administrator password at the
password prompt. Start the Setup utility and reset the power-on password.
v Remove the battery from the server, wait 30 seconds, and then reinstall it.
v Change the position of the power-on password switch (switch 4) on the system
board switch block (SW3) to bypass the power-on password check (see Table 2
on page 30 for more information).
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.
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.
