Step 6—Connect SCSI Cables

Connect the SCSI cables to SCSI devices, as shown in Figure 8-6. PERC 3/SC provides two SCSI connectors:

J11, the SCSI channel internal high-density 68-pin connector for Wide (16-bit) SCSI

J13, the SCSI channel external ultra high-density 68-pin connector for Wide (16-bit) SCSI

Make sure all cables are properly attached, and that the PERC 3/SC card is properly installed.

The cable length should not exceed 3 meters for Fast SCSI (10 MB/s) devices or single ended 1.5 meters for Ultra SCSI devices. The cable length can be up to 12 meters for low voltage differential (LVD) devices.

The cable length should not exceed six meters for non-Fast SCSI devices.
