Appendix A SCSI Cables and 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

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

30)

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