Step 8 Connect SCSI Cables
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:
Step Action
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.
