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.
