Every Sun Ray Client contains a firmware module that handles the following items:
Power-on self test (POST)
Client initialization
Authentication
Low-level input and output, such as keyboard, mouse, and display information.
To accommodate customers with differing requirements for flexibility and security, the Sun Ray Client firmware can be used in two ways:
Default mode where the firmware uses the configuration
provided by the Sun Ray server's .parms
file.
Local configuration mode where the firmware uses the Sun Ray Client's local configuration that a user can update through a Graphical User Interface (GUI) tool, called the Sun Ray Local Configuration GUI or Configuration GUI (previously called the Pop-up GUI).
A Sun Ray Client's local configuration values are checked first during the Sun Ray Client initialization, so this mode enables users to individually configure a Sun Ray Client's behavior at the local level. To make the Configuration GUI available to users on Sun Ray Clients, you must specifically enable it with the utfwadm command.
