A serial attached SCSI (SAS) backplane and detection system thereof are provided. When a first SAS backplane is not serially connected to a second SAS backplane, a logic signal with first status value provided by a signal unit of first SAS backplane is output to a master control unit through a second pin. When the first SAS backplane is serially connected to the second SAS backplane, a logic signal with second status value provided by a signal unit of second SAS backplane is transmitted to a first pin of the first SAS backplane though a third pin of second SAS backplane and output to the master control unit through the second pin of first SAS backplane. Therefore, the master control unit determines whether the first SAS backplane is serially connected to the second SAS backplane according to the received logic signal with the first or the second status value.
