(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.
