A SCSI Cables and Connectors
SCSI Connectors
MegaRAID Express 500 provides several different types of SCSI connectors. The
connectors are:
• one 68-pin high density internal connector
• one 68-pin ultra high density external connector
68-Pin High Density SCSI Internal Connector
The SCSI channel on the MegaRAID Express 500 Controller has a 68-pin high density
0.050 inch pitch unshielded connector.
This connector provides all signals needed to connect MegaRAID Express 500 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
• 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
