SCSI Backplane Option
This document describes the optional small computer system interface (SCSI) back-
plane for the Dell PowerEdge 6300 and 4x00 systems.
The 1 x 8 SCSI backplane provides hot-pluggable Ultra2/LVD SCSI connections for up
to eight 1-inch hard-disk drives in the system’s internal drive compartment. Except for
the added SCSI connections provided on the board, the 1 x 8 backplane is identical to
the 1 x 6 backplane in features and functionality (for example, the cable connectors on
both backplanes are identical). For a description of the SCSI backplane, refer to your
system User’s Guide and Installation and Troubleshooting Guide.
NOTE: Before you install the 1 x 8 backplane, verify that your system chassis supports
it. Check the back of your system for a label (located between the connectors and the
first power supply) that specifies that your chassis supports the 1 x 8 backplane. If you
do not find a label, you may not be able to use the 1 x 8 backplane in your system
chassis. Contact your Dell representative for further information and instructions.
Installing a SCSI Backplane
WARNING: The power supplies in this computer system produce high volt-
ages and energy hazards, which can cause bodily harm. Only trained
service technicians are authorized to remove the computer cover and
access any of the components inside the computer.
NOTE: You can use only 1-inch hard-disk drives with the 1 x 8 backplane. You
cannot use 1.6-inch hard-disk drives with the 1 x 8 backplane. To work with the
1 x 8 backplane, you need to convert the drive carriers to the 1-inch width by removing
the spacer insert that fastens to each carrier adjacent to the carrier release handle.
To replace a SCSI backplane board with a different backplane board, perform the fol-
lowing steps.
