Intel® Server Chassis SC1400UP / Intel® Server Platform SR1425BK1-E 3.3.3 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.
