3.2.2 The SCSI Interface
The SCSI interface conforms to ANSI X3T10.11/1142.
The SCSI interface operates as two 16-bit, SE or LVD channels, and
supports Fast, Ultra, Ultra2, and Ultra160 SCSI protocols. The interface
is made through connectors J2, J3, and J4 for Channel A and J5 for
Channel B.
J2 is a 68-pin high density right-angle connector for internal SCSI
connections to Channel A. J3 is a 50-pin high density right-angle
connector that protrudes through the ISA/EISA bracket for external
connections to Channel A. Also on Channel A is connector J4, which is
a 50-pin narrow (ribbon) connector for internal connections. Channel A
has autosensing, active SE SCSI termination.
J5 is a 68-pin high density latching right-angle connector for internal
SCSI connections to Channel B. Channel B has active, SE or LVD SCSI
termination that is always enabled.
SCSI TERMPWR is supplied by the board.
Tables 3.4, 3.5, 3.6,and3.7 document the signal assignments for J2, J3,
J4 and J5 respectively.
