Chapter 2 - Installation Quick Start
2 If the drive has an IDE interface, connect the other end of the ribbon cable to its
associated Mux connector, insuring that pin 1 of the cable mates with pin 1 of the Mux
connector. See Figure 2-10.
3 Connect the power cable associated with the SBC to the disk drive ensuring that pin 1 of
the cable mates with pin 1 of the drive connector. The power cables are a Y-cable with a
small connector for a floppy disk drive and a large connector for a hard disk drive. See
Figure 2-11.
Note: The Y-cables are labeled from 1 to 9 on all three connectors of each cable. The power
cables are associated with the subsegments of the five segments labeled on the backplane. The
power cable for segment 1 is labeled 1. The two power cables associated with segment 3 are
labeled as subsegment 1 power cable being labeled as 4 and subsegment 2 power cable being
labeled as 5.

4 If you are cabling multiple drives, repeat steps 1-3 until complete. When you are finished,
slide the 8-bay disk drive chassis all the way into the MultiArray and tighten the back two
mounting screws and replace the two front mounting screws. If you are installing a drive
in the horizontal drive chassis, proceed to the next section. If your installation is
complete, proceed to the External Cabling section of this chapter.
