Remove a storage interposer (lower tray)

The lower storage interposer is in the lower compute tray that is accessed from the front of the server. After removing the lower compute tray and fan cage, disconnect the RAID card from the storage interposer and lift it out of the way; then, remove the screw securing the storage interposer and remove the storage interposer from the compute tray.
