(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.
(4) External operator panel (MP model only)
The external operator panel is installed only when required for the system. When connection is not
required, leave open the following pins in the external operator panel connector of the IDD : Pins
21, 22 and pins 01 through 08 in CN2 and pins A1 through A12 in CN1.
