Operational Environment A-7
A.2.2 The SCSI Interface
The SCSI interface operates as a 8-bit or 16-bit, synchronous or
asynchronous, differential bus, and supports SCSI-2 protocols and 16-bit
arbitration. The interface is made through connectors J2 and J3 for
Channel A. Channel B connectors are J5 and J6. Connectors J2 and J5
are 68-pin high density right-angle receptacles for internal connections.
Connectors J3 and J6 are 68-pin VHDCI right-angle receptacles that
protrude through the back panel bracket.
Active differential SCSI termination is provided automatically. SCSI
TERMPWR is also supplied by the board.
Table A.4 and Table A.5 show
the signal assignments for J2/J5, and J3/J6.
