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
30)
•
cable assembly for converting from internal wide to internal non-wide SCSI connectors
