[1]For environments where all elements of the bus (cables, device inter- faces, environmental noise and other parameters) are controlled to be better than minimally required, it may be possible to extend the path length and device count.
[2]SCSI devices shall be within a stub length of the termination (.1 meter).
[3]Values specified by data rate shall apply even if a slower data rate is negotiated.
[4]Loads spaced at least eight inches (20.3 cm) apart (cables). (Refer to SCSI EPI T10/1143D specification.)
