6 SCSI Backplane

6.1 Introduction

The SCSI backplane provides nine fan headers for the system fans, two SCSI SCA drive
connectors, and a power connector for the optional CDROM. This board is located between the
system fans and the front drive bays. The figure below depicts the layout of the SCSI backplane.
