Medalist Pro Installation Guide, Rev. B 27
[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 8 inches (20.3 cm) apart (refer to SCSI EPI
T10/1143D specification).
[5] See ANSI T10/1302D specification for details.
