    Notes:
    • Beaconing - card's signal to other devices on the network that a hard error has occurred. The card can remove itself from the network and conduct self-tests to determine if it is causing the problem.
    • Hard error - a problem that requires removal of the source of the error or reconfiguration of the network before the network can resume reliable operation.
    • The card is open when it has established connection with other devices on the network.
    • A wire fault is an error caused by a break or a short circuit in the cable that connects the card to its access unit.
