SCSI Cables and

Connectors

The MegaRAID SCSI 320-2 provides several different types of SCSI connectors. The connectors are:

•Two 68-pin high density internal connectors

•Two 68-pin very high density external connectors

A.1 68-Pin High-Density SCSI Internal Connector

Each SCSI channel on the MegaRAID SCSI 320-2 controller has a 68-pin high density 0.050 inch pitch unshielded connector.

These connectors provide all signals needed to connect the MegaRAID SCSI 320-2 to Wide SCSI devices. The connector pinouts are for a single-ended primary bus (P-CABLE) as specified in SCSI-3 Parallel Interface X3T9.2, Project 885-D, revision 12b, dated July 2, 1993.

The cable assemblies that interface with the 68-pin connector are:

•Flat ribbon or twisted pair cable for connecting internal Wide SCSI devices

•Round shielded cable for connecting external Wide SCSI devices
