(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.
