A SCSI Cables and Connectors

SCSI Connectors

MegaRAID provides several different types of SCSI connectors for each channel. The connectors are:

•68-pin high density internal connectors

•68-pin ultra high density external connectors

68-Pin High Density SCSI Internal Connectors

Each of the SCSI channels on the MegaRAID has a 68-pin high density 0.050 inch pitch unshielded connector.

These connectors provide all signals needed to connect MegaRAID 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, date July 2, 1993.

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

•flat ribbon or twisted pair cable for connecting internal wide SCSI devices

•flat ribbon or twisted pair cable for connecting internal and external wide SCSI devices

•cable assembly for converting from internal wide SCSI connectors to internal non-wide (Type

2)connectors

•cable assembly for converting from internal wide to internal non-wide SCSI connectors (Type

•cable assembly for converting from internal wide to internal non-wide SCSI connectors
