(1)

SCSI cable

See Section 1.3, “Physical Requirements”, and Section 1.4, “Electrical Requirements”, in
SCSI Physical Interface Specifications.

(2)

Power cable

IDDs 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 IDD because no fasten terminal
dedicated to SG is provided with the IDD.  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.
