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.
