A.2.2 The SCSI Interface

The SCSI interface conforms to ANSI X 3T10.11/1142. The SCSI interface operates as 16-bit, synchronous or asynchronous, SE or LVD, and supports Ultra160 SCSI protocols. Arbitration is supported for 8-bit (at lower SCSI speeds) and 16-bit. Active SE or LVD SCSI termination is provided automatically. SCSI termination power is supplied by the board.

Connector J3 is a 68-pin HD right angle connector that protrudes through the back panel bracket and is used for external connections. Connector J4 is a 68-pin HD right angle header used for internal connections.

Table A.4 and Table A.5 show the signal assignments for J4 and J3 respectively.
