Chapter 6: Advanced Chassis Setup
SCA Backplane
The SCSI drives plug into a SAF-TE compliant SCA backplane that provides
power, SCSI ID and bus termination. A RAID controller can be used with
the SCA backplane to provide data security. The operating system you use
must have RAID support to enable the hot-swap capability of the SCSI
drive.
The SCA SCSI backplane is already preconfigured; there are no
jumpers or switches.

Installing a Component in the 5.25" Drive Bays
1. Mounting the component in the drive carrier
A component such as an IDE hard drive or an additional SCSI drive that
can fit into a standard IDE drive bay can be mounted in the 5.25" drive bay.
The component should also be mounted in a drive carrier to simplify its
installation and removal from the chassis. The carrier also helps promote
proper airflow. For this reason, even an empty carrier without a component
installed must remain in the chassis. To add a component such as those
noted above, install a drive into the carrier with the printed circuit board side
toward the carrier so that the mounting holes align with those in the carrier.
Secure the drive to the carrier with the four screws.
