Supervisor and Hard Disk Passwords: The
supervisor password and the hard disk password (HDP)
are security features that are used to protect the system
and the hard disk data from unauthorized access. No
overriding capability is provided. If only a hard disk
password is set, obtaining permission from the password
owner to unlock the password is a prerequisite for running
diagnostic tests and performing service. If both supervisor
password and hard disk password are set, you can enter
Easy-Setup by pressing the Enter key or power-on
password at the supervisor password prompt. In this case,
the Password, Start up, and Initialize icons cannot be
selected.
See “Password Combinations (POP, HDP, PAP)” on
page 451 for more information about passwords.
Note: The supervisor password and hard disk password
cannot be replaced If they are forgotten. If the
customer forgets the supervisor password, the
system board must be replaced. If the customer
forgets the hard disk password, the hard disk drive
must be replaced.
Power Shutdown Switch: Thepower shutdown
switch resets the system regardless of the microcode
status and forces the power off. Use this push button to
power-off when power is not completely off or the
microcode is in a hung state.
See “Rear View” on page 504 for the power shutdown
switch.
