SCSI Cables and
Connectors
MegaRAID SCSI 320-1 provides several different types of SCSI
connectors. The connectors are:
· One 68-pin high density internal connector
· One 68-pin very high density external connector
A.1 68-Pin High-Density SCSI Internal Connector
The SCSI channel on the MegaRAID SCSI 320-1 controller has a 68-pin
high density 0.050 inch pitch unshielded connector.
This connector provides all signals needed to connect MegaRAID SCSI
320-1 to Wide SCSI devices. The following connector pinouts are
provided for both single-ended and differential primary bus (P-CABLE) as
specified in the SPI (SCSI Parallel Interface) documentation.
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
