(1) SCSI cable
Refer to Section 1.3 "Physical Requirements" and Section 1.4 "Electrical Requirements" of the
SCSI Physical Interface Specifications.
(2) Power cable
HDDs must be star-connected to the DC power supply (one to one connection) to reduce the
influence of load variations.
(3) DC ground
The DC ground cable must always be connected to the HDD because no fasten tab dedicated to SG is
provided with the HDD. Therefore, when SG and FG are connected in the system, it is necessary to
connect SG and FG at the power supply or to connect SG of the power supply to FG of the system.
