Cables
• The standard internal five connector wide SCSI cable includes (see
Figure 7-1):
− One wide SCSI 68-pin connector to connect to the wide
SCSI host adapter (A, Figure 7-1).
− Three wide-to-narrow adapters to connect to the narrow
CD-ROM drive and other narrow devices (B, Figure 7-1).
− One wide connector to connect the SCSI host adapter to
channel A of the storage backplane. A cable terminator is
supplied if this connector is not used to connect to the
storage backplane (C, Figure 7-1).
