SCSI Connector
u
The SCSI connector uses MCBL102A and connects to J26 on the I/O expansion board. Refer to
the table “J26, MCBL102A, SCSI” on page 63 for the cable pinout.
u
Settings for mode select header, which sets SCSI ID, parity, and other drive functionality are
printed on the CD-ROM drive. Default SCSI ID for the drive is 4.
u
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.
u
The power connector uses MCBL085A power supply cable from the power distribution board.
See the table “J8, MCBL085A, SCSI Drive Power” on page 73 the for pinout.
u
InterServe 650, 660 and StudioZ RAX systems do not use an audio cable attached to the CD-ROM
drive. However, the drive’s audio playback can be used if an audio adapter is installed and
connected to the drive. The following table shows the audio connector pinout.
