Remove the device in reverse order of the installation steps.
IMPORTANT:
„ To remove a cable from the signal connector, pull out the cable with
holding the pull-tab on the cable connector. Pulling out the cable
with holding the cable may make some pins bent and/or some
internal wires disconnected. This may cause a malfunction to
occur

If you leave the 5.25-inch device bay empty, install a dummy cover
on the bay for proper cooling and airflow. Installing a device in the
bay or covering the bay with a dummy cover protects the System
EMI integrity and cooling. When you install a drive, save the
dummy cover to reinstall if you should later remove the drive and
not reinstall one in the same bay.
