SCSI Backplane Connector Definitions

As a multi-functional board, several different connectors can be found on the SCSI backplane.
This section defines the purpose and pin-out associated with each connector.
3.3.3.1 Power Connector (Backplane to Power Supply Harness)
The SCSI backplane provides power to the three drive bays supporting up to three hard disk
drives and the slim-line drive bay supporting one floppy drive or CD-ROM drive. A 6-pin power
cable is routed from the power distribution board and plugs into a 2 x 3 shrouded plastic PC
power connector on the SCSI backplane. The following table shows the power connector
pinout.

Table 8. SCSI Backplane Power Connector Pinout (J1)

3.3.3.2 SCSI Connector (Backplane to SCSI add-in card)
A 68-pin SCSI cable is used to interface the SCSI backplane with an add-in PCI SCSI controller
installed on the PCI riser card.
