Dell™ PowerEdge™ Systems —
Installing the External Drive Bay
This document describes how to install the external drive bay assembly in your Dell
PowerEdge system. The drive bay assembly allows up to two 1-inch hard-disk drives
to be installed in the external drive bay using hard-disk drive carriers. SCSI connectors
are built into the drive bay assembly to enable easy installation and removal of the
drive carriers. The drive bay assembly is connected to one of the SCSI controllers on
the system board.
This document applies to kits with external drive bays holding up to two 1-inch hard-
disk drives in 5U and 7U height PowerEdge systems. It does not apply to external
drive bay kits holding a single 1-inch hard-disk drive.
NOTICE: Hot-pluggable drive installation and removal is not supported for
hard-disk drives installed in the external drive bay. Removing a drive while the
system is turned on will result in a loss of data.
Before You Begin
Only trained service technicians are authorized to install hard-disk drives in the sys-
tem's external drive bay. Refer to the safety instructions at the beginning of your
Installation and Troubleshooting Guide for important information about accessing the
interior of your system.
