Power-on password:
If a power-on password is set, when you turn on the server, the system startup
will not be completed until you type the power-on password. You can use any
combination of 6 to 20 printable 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 6) on the system
board switch block (SW7) to bypass the power-on password check (see Table 3
on page 29 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 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 SW7 is Off.
