If a drive is already installed in the bracket, disconnect the DC power
cable and interface cable from the back of the drive before removing
the bracket from the chassis. To remove the old drive from the bracket,
remove the four screws that secure the drive in the bracket (see the
following figure).
4 Unpack the drive and prepare it for installation.
NOTICE: Ground yourself by touching an unpainted metal surface on the
back of the computer.
See the documentation that accompanied the drive to verify that the
drive is configured for your computer. Change any settings necessary
for your configuration.
5 Slide the drive into one of bracket bays, oriented so that the
connectors on the back of the drive will face the interior of the chassis
when the bracket is reinstalled (see the following figure).
