SCSI Connectors

The PERC 3/DC and PERC 3/DCL adapter has two types of SCSI connectors:

•Two 68-pin high density internal connectors

•Two 68-pin external ultra-high-density connectors

Only one connector type can be used for the SCSI channel at any one time.

SCSI Termination

PERC 3/DC and PERC 3/DCL uses active termination on the SCSI bus conforming to SCSI-2 and SCSI-3 specifications. Termination enable/disable is automatic through cable detection.

SCSI Firmware

The PERC 3/DC and PERC 3/DCL firmware handles all RAID and SCSI command processing and supports the feature listed in Table 5-8.
