Step 1. Disconnect all power and data cables on the hard disk drive backplane that go to the storage
interposer or to connectors on the system board or optional storage tray. You might find it easier to
disconnect cables from the backplane if you disconnect them from the storage interposer first,
reconnecting them to the storage interposer after removing the backplane or installing a new one.
Other cables might also need to be removed from their retaining clips or moved to the side to
remove the backplane.
Step 2. Turn the tray right-side up.
Step 3. Remove the hard disk drive backplane.
