Seagate ST34573N/W/WD/LW/WC/LC 사용자 설명서

Barracuda 9LP Installation Guide, Rev. E

[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] Low voltage differential (LVD) devices only (“LW” models).

Twisted pair cable should be used with differential transceivers.
