Table 4 Computer Setup—Security (continued)

NOTE: Computer Setup's "Apply Defaults and Exit" option is prohibited while a virtual appliance is installed.

●Virtual Appliance Configuration Interface (unlock/lock) Controls software access to the VA 3.0 configuration interfaces.

Smart Card BIOS Password Support (some models) (enable/disable) Allows the user to enable/ disable the Smart Card to be used in place of the Setup and Power-On Passwords. This setting requires additional initialization within ProtectTools® before this option will take effect.

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.
