Electronic device adaptable for fibre channel arbitrated loop and method for detecting wrong condition in FC-AL

摘要

Error detection in a fiber-channel arbitrated loop (FC-AL) is facilitated by incorporating certain error detection circuitry in FC-AL adapted electronic devices. Transmission circuitry is provided to transmit diagnostic frames during periods when the electronic device has no pending output transactions. Receiver circuitry is provided to perform CRC checking of each received frame.
