SCSI Connector
The audio connector uses MCBLZ630 and connects to J22 on the system board. Refer to Chapter
5 or 6 for the cable pinout.
The SCSI connector uses MCBL234A and connects to the riser card.
Settings for mode select header, which sets SCSI ID, parity, and other drive functionality are
printed on the CD-ROM drive.
Terminator resistors are installed in the terminator sockets only when active termination is
required. By default, these sockets are empty since termination is provided by the SCSI cable.
The power connector uses power supply cable P6 from the power supply. Refer to Chapter 10,
“Power Supply and Fans,” for the cable pinout.
