Integrated SCSI–2 bus connector
An external connector for the integrated SCSI bus is located on the
rear panel of every AViiON 5500 and 550 series computer. Some
systems may include as many as four expansion SCSI buses; see the
next section for information about a SCSI expansion bus connector.
The integrated SCSI–2 bus port contains a 50–position, male
P&S–style connector. Figure A–5 shows the position numbering for
the connector.
