Setup Security Level Provides a method to allow end-users limited access to change specified setup options, without
having to know the Setup Password.
This feature allows the administrator the flexibility to protect changes to essential setup options,
while allowing the user to view system settings and configure nonessential options. The administrator
specifies access rights to individual setup options on a case-by-case basis via the Setup Security
Level menu. By default, all setup options are assigned Setup Password, indicating the user must
enter the correct Setup Password during POST to make changes to any of the options. The
administrator may set individual items to None, indicating the user can make changes to the specified
options when setup has been accessed with invalid passwords. The choice, None, is replaced by
Power-On Password if a Power-On Password is enabled.
NOTE: Setup Browse Mode must be set to Enable in order for the user to enter Setup without
knowing the setup password.
