Token-Ring Table Terms and Definitions
Auto-removal The state in which a token-ring adapter port removes itself from
the network to perform self-tests to verify that is not the cause of
hard error. If the tests are successful, the port will reattach itself
to the network.
Beaconing The state that a token-ring adapter port enters after it has
detected a hard error. The error condition is reported to the other
devices on the network. Beaconing can result in the port
removing itself from the network (auto-removal) to determine
whether or not it is the cause of the hard error.
Hard error An error condition on a network that requires removing the source
of the error or reconfiguring the network before the network can
resume reliable operation.
Initialization The first step taken to prepare the port for use after the computer
has been booted. During initialization, the port runs a series of
internal self-diagnostic tests.
Open The state in which the port has established connection with other
devices on the ring.
Wire fault An error condition caused by a break or short circuit in the cable
segment that connects the port to its access unit, such as an IBM
8230 Token-Ring Network Controller Access Unit.
