Passwords
From the System Security choice, you can set, change, and delete a power-on
password and an administrator password. The System Security choice is on the
full Configuration/Setup menu only.
If you set only a power-on password, you must type the power-on password to
complete the system startup, and you have access to the full Configuration/Setup
Utility menu.
An administrator password is intended to be used by a system administrator; it
limits access to the full Configuration/Setup Utility menu. If you set only an
administrator password, you do not have to type a password to complete the
system startup, but you must type the administrator password to access the
Configuration/Setup Utility menu.
If you set a power-on password for a user and an administrator password for a
system administrator, you can type either password to complete the system startup.
A system administrator who types the administrator password has access to the full
Configuration/Setup Utility menu; the system administrator can give the user
authority to set, change, and delete the power-on password. A user who types the
power-on password has access to only the limited Configuration/Setup Utility menu;
the user can set, change, and delete the power-on password, if the system
administrator has given the user that authority.
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 up to seven characters (A–Z, a–z, and 0–9) 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:
