Abstract
A method and apparatus for recovery from faults in a loop network () is provided. The loop network () has a plurality of ports () serially connected with means for bypassing the ports () from the loop network (). A control device () is provided with bypass control over at least one of the ports (). A host means () sends a command to the control device () at regular intervals and the control device () has a counter which restarts a time period at the receipt of each command. If the time period expires, the control device () activates the means for bypassing all the ports () under its control. The loop network () may have two loops () with at least some of the ports () common to both loops ().
