Abstract:
1. A method for automatically configuring a Serial Attached SCSI (SAS) compliant device to properly receive and transmit signals to a connected device, comprising: detecting a first OOB signal transmitted from the connected device on a receive pin of the SAS compliant device; entering into a first crossover mode in which the receive pin of the SAS compliant device is switched to a different pin of the connected device if the first OOB signal transmitted from the connected device is not detected; turning off a transmit signal of the SAS compliant device when the internal connections are switched; listening for a second OOB signal transmitted from the connected device after switching during the first crossover mode; and entering into a second crossover mode if the second OOB signal is detected at the receive pin of the SAS compliant device.
