If implemented, IEEE 1394 must meet the requirements defined in B2.2. Notably, externally accessible IEEE 1394 sockets are required when external access is provided. Internal-only IEEE 1394 implementations are also allowed.
Devices provided as expansion devices must be capable of being remotely managed so that control and Total Cost of Ownership (TCO) policies can be realized. For example, for any implementation of a floppy disk drive on a system, the drive must be capable of being remotely disabled as a boot selection and provisions must be made for locking.
Certain devices are not required to be capable of being remotely disabled, including the primary HDD, the network adapter, and any standard devices that use legacy connections, such as a keyboard or pointing device that uses a PS/2-compatible connection. However, it must be possible that permissions, policies, or other methods can be used to remotely manage capabilities such as hard disk access or to control end-user ability to change the MAC address or configuration settings for the network adapter.
