Step 6—Select and Set Target IDs for SCSI Devices

Set target identifiers (TIDs) on the SCSI devices. Each device in a specific SCSI channel must have a unique TID in that channel. See the documentation for each SCSI device to set the TIDs. The PERC 3/DC or PERC 3/DCL controller automatically occupies TID 7 in the SCSI channel. 8-bit SCSI devices can use the TIDs from 0 to 6 only. 16-bit devices can use the TIDs from 0 to 15. The arbitration priority for a SCSI device depends on its TID.

Step 7—Connect SCSI Cables

Connect SCSI cables to SCSI devices. PERC 3/DC or PERC 3/DCL provides internal SCSI connectors, J4 and J5, which are the SCSI channel internal high-density 68-pin connectors for Wide (16-bit) SCSI. PERC 3/DC or PERC 3/DCL also provides two external SCSI connectors: J7 and J15, the SCSI channel external ultra high-density 68-pin connectors for Wide (16-bit) SCSI. Make sure pin 1 on the card is connected to pin 1 of the cable.
