Connect SCSI cables to SCSI devices. MegaRAID Express 500 provides two SCSI
connectors: J11, the SCSI channel internal high-density 68-pin connector for Wide (16-
bit) SCSI and J13, the SCSI channel external ultra high-density 68-pin connector for
Wide (16-bit) SCSI.

Connect SCSI Devices Use the following procedure to connect SCSI devices:

1

Disable termination on any SCSI device that does not sit at the end of the
SCSI bus.

2

Configure all SCSI devices to supply TermPWR.

3

Set proper target IDs (TIDs) for all SCSI devices.

4

The cable length should not exceed three 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 LVD devices.

5

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